    Willem Kmetsch 

Willem Kmetsch
Voiced by: Ryohei Arai (Japanese), Micah Solusod (English)

The last human alive, and officially one of the caretakers of the weapons storehouse. He develops a life similar to that of 500 years ago, caring for children, before realizing that the children are weapons. He strives to prevent the deaths of the children by teaching them the correct way of using their dug weapons.

  • Accidental Pervert: The first time it happened both him and Chtholly are the offenders, where the montage of their first meeting includes walking in on an Ambiguous Gender Frogger in the bath. Then it was with Phyra (see her Berserk Button below), though no one could really fault him with this one since he didn't have any clue why she was offended in the first place until she explained. The third time was him unintentionally touching the now conscious Elq's chest in the fifth volume.
  • The Ace: Among the Quasi-Braves. In his pursuit to become a full Brave, Willem mastered various arts and techniques, including weapon maintenance, which allowed him to stand in the front lines of battle. He is definitely seen as this by the army in the present, even if he can't fight at his fullest anymore.
    • Broken Ace: Of course, no matter how hard he trained, his efforts were always never enough to become a full Regal Brave like he's always wanted. That, and there's his Survivor's Guilt of being the only human left when all his old friends and previous family died many, many years beforehand...
  • Adaptational Heroism: Downplayed example in that while both his LN and anime incarnations retain his essential kind and heroic nature, the anime toned down some of his crasser moments to make him less of a Jerkass than his light novel self who had way less tact than his anime counterpart.
  • Almighty Janitor:
    • Though skilled and powerful from what amounts to be the level-grinding he did to be where he was back when he was still in his prime, Willem's rank as a Quasi-Brave means he is of significantly lower standing compared to the supposedly more monstrous Regal Braves when the humans still flourished the lands. Considering how strong Willem is in the present even though he's a Dented Iron incapable of using his Venenum for a few minutes lest it risks killing him, it says a lot about how powerful the emnetwihts were back in the day.
    • Also his current job as co-caretaker of the Warehouse. As Technical Officer, he doesn't actually have any true ranking in the military, and all his job amounts to is just for the Guardian Wings Military to have a representative at the facility (per an agreement between the Guard and the Orlandri Federation). Souwong lampshades this that with the skills that Willem has, they are not going to be put to any use at the Warehouse.
  • Always a Bigger Fish: Elpis unleashed a wave of Aurora on Island 11 for a "demonstration" of their weapons. Unfortunately for them, a much more powerful Beast, Shiantor (a.k.a. Willem), is in the city as well, making short work of Elpis' weapons.
  • And I Must Scream: The petrification that he undergoes after defeating Ebon Candle took longer than Willem thought (that, and Willem is getting petrified from the feet up), and he even had to strike up an awkward conversation with Ebo while it's still taking effect. In the end Ebo has succumbed to his injuries faster than Willem's own petrification, to his mild annoyance.
  • And Then John Was a Zombie: He starts turning into a Beast at the end of volume 4.
  • Anger Born of Worry: He gets angry at Chtholly for using venenum to save Almita from falling from the 2nd floor, because he knows that doing so would only further deteriorate Chtholly's mental state.
  • Arson, Murder, and Jaywalking: His request to the Sage is for Chtholly to retire from the front lines (excusing it as "research" on Willem's part) and to raise the Warehouse's grocery budget. The second bit was excised from the anime.
  • Arbitrary Skepticism: Amusingly, in spite of Willem growing up in a medieval fantasy setting, he was under the belief that trolls are merely mythical creatures until he meets one in person. That person being Nygglatho in the present day.
  • Be Careful What You Wish For: In the past his primary goal was to become a regal brave. He gets his wish at the end of the light novels. All it took was the loss of nearly everyone he cared about and the sacrifice of his own future for the sake of others.
  • Berserk Button: Getting Mistaken for Pedophile.
  • Big Brother Instinct: Both in the past and in the present. Being the eldest person both times probably helps.
  • Bishōnen Line: By the series epilogue, Willem is apparently able to completely control his Beast side, allowing him to return home to the Warehouse without endangering anyone. That he doesn't raise any alarms (and Nygglatho recognizes him in their reunion) also implies that he kept his human form.
  • Boring, but Practical: His ability to tune swords is nowhere near as exciting as some of the abilities his former comrades possessed. In the present day, however, it’s an invaluable skill with the potential to turn the tide of the war against the Beasts.
  • Brain Bleach: Apparently, seeing the contents of a Reptrace lunchbox causes him to nearly throw up.
  • Brick Joke: Gets crushed underneath Chtholly during their first meeting when he tries to break her fall and Pannibal who was trying to assault him on two separate occasions. Internally, Chtholly hopes Willem is not into that sort of thing. The novel ends with Willem saving Ryehl in a manner that mirrors both of his first encounters with the two girls.
  • Cartwright Curse: He’s a walking example of this trope. In the past he had some major Ship Tease with Lillia and Almaria. Unfortunately, Lillia is turned into a brain dead husk by Elq’s Mind Rape while Almaria transforms into an Eldritch Abomination that Willem is forced to personally kill. He tries to avert this with Chtholly only to watch helplessly as she sacrifices her life in order to save his. Even a female adventurer that develops a crush on him in Volume 4 ends up dying horribly.
  • Cassandra Truth:
    • Both Nygglatho and Limeskin have difficulty believing that Willem is friends with the Great Sage.
    • When a fellow Plantagenista crew member cautioned him about laying his hands on a Dug Weapon, Willem assures him that he knows what he's doing, because he is an Emnetwiht. The crew member doesn't believe him, and thinks Willem is just being delusional.
  • Change the Uncomfortable Subject: When Lakhesh starts treating Willem like he's an actual father to her and her sisters, Willem was flattered. But then she started wondering who she would call her mother, Willem completely ignores the rest of her words (in the anime, he softly pushes Lakesh out of the kitchen), just as she mentions Nyglattho and Chtholly...
    • It also happens happens when he’s describing the different kinds of barrier worlds created by demons to Nephren. He almost ends up telling her about the time he was captured by a succubus, before realizing that particular story wasn’t exactly PG. He quickly changes the subject much to Nephren’s dismay.
  • Chick Magnet: Has more than his fair share of female admirers in both the past and present. Unlike most examples of this trope he is perfectly aware of this.
  • Children Raise You: He spent his time after being resurrected having Survivor's Guilt with nary a care what he wants to do with the rest of his life. It was upon meeting the Fairies and becoming their "father" that Willem finds a new purpose.
  • Crazy Jealous Guy: One way to interpret his hostility towards Ted's infatuation with Almaria.
  • Cosmic Plaything: The guy has tragedy following him at every turn.
  • Covered in Scars: His body still carries the marks of injuries he sustained back when he still fought as a Quasi-Brave in the front lines.
  • Covert Pervert: Downplayed, in that it doesn't crop up much. When seeing a statue of Règles Aile's Great Sage that Willem may or may not have recognized yet as his old friend Souwong he mentions that he can't appreciate statues of men; women, on the other hand, are another story. In the anime he pretends to invoke the image of a molester when asking Chtholly if she needed more of his "special massage". And then there's Chtholly (Ren in the anime) sensing that there are naughty thoughts coming from Willem's head when hearing Rhan's suggestive moans while being massaged. The novels also have a dream Willem had where he was invited to a drinking session with the Emperor, Nils and Navrutri, who are all showing off their respective romantic misadventures; after one drink Willem started bragging about his own experiences, dropping several girls' names before finally waking up.
  • Create Your Own Villain: He invokes this trope on himself near the end of the light novel. By unleashing his beast side and attacking the Leprechauns he allowed them regain their purpose as the guardians of Règles Aile by defeating him. This foiled the plans of the group that was planning to dismantle the Warehouse and seize the fairies there.
  • Dangerous Forbidden Technique: Due to his injuries he is unable to use any of his old abilities without putting himself at serious risk of death. This also happens when he taps into his Beast side, as accessing those powers causes him to succumb to his bestial instincts within minutes.
  • Dark and Troubled Past: Was a former Quasi-Brave who couldn’t become a full Brave. That, and the fact that his adopted family from his previous life as well as the rest of the human race are now dead in spite of his promise of returning to them...
  • Dead Man Walking The extent of his injuries in the past before being frozen in time should be enough for him to literally die, but he keeps going. His likelihood of dying increases whenever he tries to exert himself in battle.
  • Deadpan Snarker: He makes witty remarks sometimes with a straight face on the whole time.
  • Death Seeker: Chtholly surmises that the reason he's itching for a fight whenever the opportunity rises is because he's this. He later admits that she was right and that he was intentionally trying to get himself killed during the battle on the Plantagenista.
  • Declaration of Protection: Towards Chtholly, promising to make her happy for as long as he lived. He fails. He also extends this to the rest of the girls in the Warehouse.
  • Dented Iron: While he was shown as a capable soldier in the past, in the present, the numerous injuries and curses Willem accumulated during the war against the Visitors back when the humans were still around have clearly taken their toll on his body. At most, he can only fight at about a maximum of a few minutes before collapsing.
  • Despair Event Horizon: Goes through a massive one following Chtholly’s death. He gets a bit better in volume 4 only to break once again when Almaria disappears and the beasts start destroying Gomag. It gets to the point where he’s openly musing about how nice it would be to be torn apart by beasts. By the end of the volume he’s come out of it, not due to any personal growth, but because he’s been possessed by an Eldritch Abomination and can only feel joy at returning “home” to the ashen wastes.
  • Despair Speech: He gives one to Rhan, where he openly admits to being a Failure Hero who could never save those closest to him.
  • Detect Evil: Willem mentions that his training as a Quasi-Brave allowed him to feel any sense of malice around him.
  • Did You Just Have Tea With Cthulhu: It’s unclear how, but he somehow managed to open a dialogue with Shiantor; a reality warping Eldritch Abomination whose thought process was so alien even a Visitor admitted that they couldn’t comprehend it. It probably helped that Willem was also a Beast by that point, or more accurately realized he was a Beast all along. At the very least he was able to understand the Beast’s anger at losing its former home, which no doubt gave them some common ground during their ten year discussion.
  • Did You Just Punch Out Cthulhu?: Despite his lack of natural talent he managed to defeat Eboncandle through sheer tenacity. He lost most of his abilities as a result so this might also count as Broke Your Arm Punching Out Cthulhu. Still, this doesn’t stop him from defeating Shiantor in volume 4 with nothing but an improvised dug weapon cobbled together with his maintenance skill. Also possibly subverted as the beast merely decides to use him as a host once he killed its previous one.
  • Diving Save: Performs one on the final episode to save Nephren from falling to her death.
  • Expy:
    • His relationships to the girls in the Warehouse becomes rather similar to that of Papa Nier, whilst his relationship with Chtholly resembles that of Brother Nier and Kaine. His beast form, as well as the way said form is killed is also similar to the Shadowlord from the same game.
    • His physical appearance has also led to many people seeing a resemblance between him and Guren Ichinose.
    • He shares many similarities with Wilhelm van Astrea. Their names and backgrounds sound almost identical. Both were talentless swordsmen who sought to surpass a Red Haired Heroine through sheer effort. The difference is Wilhelm succeeded with Theresa, while Willem failed with Lillia due to the war with the Visitors.
  • Face–Monster Turn: After he awakens his Beast side he’s overcome with an intense desire to “cleanse” the planet of all non Beast life and restore the “beautiful ashen plains” of the primordial world.
  • Failure Hero: The loss of his family and comrades from 500 years ago clearly weigh on him in the present day.
  • Finger Gun/This Banana is Armed: He brandishes a finger gun against the Annihilation Knights and appears to knock them out with it. In reality, the gesture was disguising the fact that he was flicking coins at his assailants with his other hand at high speed.
  • Fish out of Temporal Water: He still obviously has some trouble adjusting to the present era after being frozen for 500 years.
    • This is most obvious when it comes to culture and entertainment. Movies just confuse him, especially when all the actors are Lizardfolk, and he can never bring himself to enjoy the cinema. His confusion isn’t too surprising considering that the printing press was considered a recent invention back in his time.
  • Forced to Watch: In the anime at least, Willem is completely conscious but his body has, by that point, succumbed from numerous injuries. Thus he can only lie on the ground and watch as Chtholly protects him and Nephren from the Timmere.
  • Friend to All Children: Is great with kids, as shown with how he handles the little girls in the Warehouse in the present day and how much the kids from his orphanage in the past adored him. That saying, he's pretty bad when handling women who are around his age, as seen with his first meeting with Almaria in the light novels in a flashback.
  • From Nobody to Nightmare: He truly was a nobody with no special traits to set him apart from your average human. Yet, through sheer force of effort he managed to become one of humanity’s strongest warriors and even defeated a literal god in a one on one fight.
  • Happily Adopted: A mutual case, where he takes the role of the Fairies' surrogate father at the same time that they started seeing him in a similar light.
  • Heartbroken Badass: First, he loses Almaria and Lillia after he was petrified for more than five hundred years without ever getting to say goodbye to either of them. Then he loses Chtholly, the very person he swore to protect and make happy, immediately after he declared that he would marry her only for her to sacrifice herself to save both him and Nephren from the Timere, dying in the process. Yeah, the guy has it rough.
  • Heroic BSoD: His reaction to finding out the truth about the 17 Beasts.
  • Heroic Suicide: He tries to kill himself after he starts turning into a Beast. He eventually succeeds when he intentionally activates Seniorious’s death curse after he’s stabbed with the sword.
  • A Hero to His Hometown: Willem was viewed as a legendary hero by his fellow humans 500 years ago. For other races, however, “heroes” like Willem were legendary monsters who committed countless atrocities. Even 500 years after the extinction of humanity stories are still told about the horrifying actions of the dreaded Emnetwiht. Due to this prejudice, Willem unsurprisingly decides to keep his identity secret from all but a few people after he’s unfrozen. The nature of his Heroic Sacrifice at the end of the light novel also ensures that most of the public will remember him as a Beast who attacked Règles Aile; with only a few people knowing the true reason behind his actions.
  • House Husband: Essentially his job at the Warehouse. He, together with Nyglattho, takes care of the facility and all the fairies within, while waiting for the older fairy soldiers to come home.
  • I Ain't Got Time to Bleed: He completely ignores the many serious injuries he sustained during the airship battle. Even after briefly passing out from blood loss, he still gets back up, determined to at least save someone. He didn’t care if he died anyway. By that point he’d completely given up any hope of living and was just looking for a heroic death.
  • I Choose to Stay:
    • Both Lillia and Nyglattho believe that if someone simply asked Willem to stay by their side, he would not turn them down.
    • At the end of the light novel he’s sealed away by Seniorious after merging with Shiantor. Nils shows up in Willem’s new afterlife and offers to separate him from the beast, which would allow Willem to become a Visitor and leave the dying world behind. Willem politely declines, saying that his beast side was a part of his being that he couldn’t just abandon. He now understood that the Beasts were only trying to reclaim the home that they’d lost to the Visitors millennia ago. So rather than leave with Nils, he decides to use his new perspective to find a way to make peace with the 17 Beasts. The epilogue implies that he might have succeeded.
  • I Got a Rock: For the snowfall festival in Episode 9, he receives a scrubbing brush from Phyracorlybia due to his treatment of her in Episode 5 (see Berserk Button in her section of this page for more details). On the other hand, the Leprechauns who accompanied him in that episode were given fine dresses.
  • I Let Gwen Stacy Die: His inability to save Chtholly haunts him for the remainder of the series.
  • Imaginary Love Triangle: Willem briefly thought that Chtholly seeing Nygglatho as competition for Willem's heart was merely in the younger girl's head, but when Nygglatho reveals she does see Willem in a romantic light, Willem responded poorly.
  • Imagine Spot:
    • He has a brief one in the novels about Chtholly hooking up with a Goblin, and ponders out loud that Grick may not be a bad choice. Nygglatho, who was discussing Willem's stance on romance, was not amused that he suddenly brought Grick up out of the blue.
    • A darker one occurs in the anime where because of his knowledge of the Beasts' true nature, he pictures the Timmere he's fighting as some random people from his past.
  • Insecure Love Interest: The reason he initially has trouble reciprocating Chtholly's feelings is that he thinks he doesn't deserve a girl like her.
  • Interspecies Romance: He falls in love with Chtholly, a leprechaun. Considering he’s the last living human, this trope is a given.
  • I Owe You My Life: The reason why he owes Grick money. Grick found him and depetrified him.
  • I Take Offense to That Last One!: Nyglattho once described him as a desperate and awkward father. Willem wants her to take back the first two descriptions, but not the father part.
  • I "Uh" You, Too: While there's no arguing that they are an Official Couple by that point, when Chtholly tells Willem that she doesn't want to wait for him at the Warehouse while he goes to the surface, she doesn't want to stay apart from him anymore so she joined the expedition. Willem actually tells her the exact same thing, and Chtholly had to double back and try to confirm that it's not a proposal.
  • I Will Wait for You: He extracts a promise from Chtholly to survive the battle on the 15th island. He nearly breaks down when he learns that the Guardian Wings Military lost the battle, thinking Chtholly and the other Fairies did not survive (although they show up unharmed shortly afterward).
  • Jack-of-All-Stats: Mastered numerous abilities while he was a brave. However, his lack of talent prevented him from going as far as some of his comrades.
  • Jerk with a Heart of Gold: Has his caustic moments where he will outright refuse to help someone in desperate need even when they're begging him right to his face. But his heart is in the right place and he will usually end up helping them in the end anyway.
  • Kiss of Distraction: His kiss to Chtholly's forehead could also be a way to catch the latter off-guard so Willem can finally massage her.
  • Last of His Kind: Having been depetrified, Willem is the last surviving pure Emnetwiht.
  • Let's Get Dangerous!: The Timere that attacked the cabin he and Chtholly were staying in on episode 11 should've seen it coming when Willem was pissed off...
  • Love Confession: Gives an indirect one to Chtholly near the end of episode 10, asking her to marry him.
  • Likes Older Women: When interviewed by the younger girls during his first night in the Warehouse, one of the questions involved his type of all things. Willem's answer spread like wildfire to the rest of the Warehouse, with the last person to hear about it apparently being Chtholly. This is the reason why Chtholly is convinced Nyglattho is competition for her.
  • Made of Iron: It’s a miracle he can even function after all the injuries he’s taken.
  • The Mentor: Serves as this to Chtholly, Ithea, and Nephren in the ways of combat, teaching the girls how to wield and maintain their Carillons properly as well as some other techniques in combat, effectively making them better fighters in the battlefield than before.
  • Mismatched Eyes: Gains a golden right eye after he absorbed Shiantor and reverted back to being a Beast himself.
  • Nice Guy: For all his faults and blunt behavior, he's still this overall, a very selfless individual who dreamed of becoming a Brave because it would give him the power to save and protect people.
  • Nitro Boost: One of his abilities, which he calls "Demolishing Nightingale Dash", that allows him to quicken his movements. Notably, he has no qualms using it just to embrace Chtholly by surprise after thinking she died during the battle for the 15th island.
  • Noodle Incident:
    • He apparently had a run-in with a succubus at some point in the past. The details are left up to the audience's imagination.
    • According to Rhan, who wasn't at the Warehouse during Willem's tenure, a few new pointers (apart from the ones she already knows) have been added to the "Bathing Rules" merely because of Willem's presence.
  • No Sense of Personal Space:
    • Willem tells himself that, had he survived his battle with Ebon Candle, once he returns home he'll grab all the kids in the orphanage in a bear hug and cover them with kisses. They would call Willem creepy for it, but he wouldn't care.
    • He tends to embrace Chtholly tightly whenever he breaks down. While Chtholly was usually flustered by these gestures (especially when one of those instances occurred in the middle of Guardian Wings Military's HQ with a sizable audience), the last time it happened she decided to wing it and hug him back.
  • Only Mostly Dead: Due to merging with Shiantor he’s effectively immortal. Not even Seniorious can permanently kill him and he eventually recovers from his death-like state.
  • Overshadowed by Awesome: No matter how hard he trained he just couldn’t match his old comrades in certain departments. Ironically, some of his fellow braves saw him as a Living Legend because of this lack of natural talent.
  • Pals with Jesus: He ends up looking after Elq in volume 5 after Nils seals his memories.
  • Paper-Thin Disguise: Defied. In his first few days in the present, Willem once considered putting on fake animal ears, horns, etc. that would hide his status as a markless, let alone an Emnetwiht, but he discarded them because it only made him look silly.
  • Parental Substitute: Originally to the orphans from his home 500 years ago, who also called him "Father", and now to the young Leprechauns/Fairies from the warehouse.
  • The Promise: Willem promised Almeria that he would return home to their orphanage after his battle with the Visitors, so in exchange, and to show her he was serious about it, he asks her to make him butter cake when he comes home. Needless to say, he wasn't able to keep it. Later, Chtholly makes him promise the same thing, albeit in reverse: he would make her butter cake after her battle with the Beasts during the events of episode 4. Unlike before however, both parties got to keep their promise this time.
  • Really 700 Years Old: Willem was turned to stone 500 years ago, due to the numerous curses he accumulated fighting a 'Guardian'.
  • Red Baron: As a Quasi-Brave, he was known as the Black Agate Swordsmaster for his skills in combat.
  • Refusal of the Call: The Sage wanted to enlist Willem on a mission to forcibly take back the surface from the Beasts, but Willem, who is no longer in any shape to fight, declines.
  • Running Gag:
    • According to other characters, Willem can make some strange expressions that would often scare them.
    • In his internal monologues, he often makes a mental note to punch someone later for something they did. It's implied (especially with the end of Episode 5 of the anime) that he's followed through with those "promises".
    • Willem will flick his fingers against the forehead of any of the girls in the Warehouse whenever they say something inappropriate. Not even Chtholly and Ithea are safe from this.
  • Screw the Rules, I Have Connections!: Invoked, where he believes the Great Sage would answer his request for Chtholly to retire and live a normal life from here on out, thinking that the Sage would like the idea of Willem being indebted to him again. The ones who actually heard this request, Limeskin and Nyglattho, were rather skeptical of Willem's relationship with the Sage. It's implied the Sage did comply with his request anyway, it's just that Chtholly chooses to use her newfound freedom by simply spending more time with Willem.
  • Sealed Badass in a Can: His not quite dead corpse was at some point sealed in a coffin-like container and shipped to a secret warehouse on Island 38, where Feodor eventually finds him.
  • Shell-Shocked Veteran: The loss of everyone he once knew has left him an emotional wreck. Episode 4 implies that he has some sort of PTSD because of this.
  • Skewed Priorities: Nygglatho accuses him of this after he removes a talisman from Seniorious, a legendary weapon, and planned to use it to prevent Collon from getting nightmares while she was suffering from a cold.
  • Spanner in the Works: His presence in Corna di Luce completely ruins the Elpis Mercantile Federation’s carefully crafted plan to seize the Warehouse. He even lampshades this. Ironically, he wouldn’t even have been there if wasn’t for their overzealous salvage crews.
  • Spirit Advisor: After Feodor makes contact with his corpse a visage of Willem starts to haunt the imp.
  • Sink-or-Swim Mentor: He doesn’t hold back in his final battle against the girls, even telling them that he planned on killing them if they lost. If they couldn’t defeat him, then the Warehouse would almost certainly be shut down. Death by his hands was infinitely preferable to what Elpis was planning on doing to them. He was dead serious too; as he didn’t hesitate to break Ithea’s spine with one of his attacks, permanently crippling her in the process.
  • Suicide by Cop: Allows Lakhesh to stab him with Seniorious after fully reverting back to a Beast while still being fully conscious of what was happening around him to ensure that the Leprechauns were seen as heroes who save everyone from the dangerous Beast, i.e. him, to the public eye. Also counts as Heroic Suicide.
  • Super-Powered Evil Side: La Chanteuse becomes this to him after volume 4. At best he can control its powers for five minutes, after which he’ll be completely taken over by the beast. Oddly enough he manages to come to an understanding with the beast while they’re both sealed with Seniorious’ hex.
  • Supreme Chef: Since he's one of the oldest in the orphanage, it makes sense for him to learn to cook for the other orphans; eventually, however, he defers the position of house cook to Almaria, who he considers the better cook. In the present day, this skill is what finally earns him the affection of most of the younger fairies after an initial rough start.
  • Survivor's Guilt: Realizing that he was the only living emnetwiht left after having been frozen in stone for several centuries has clearly been eating up inside him all this time. It’s even somewhat implied that he was considering suicide prior to his arrival at the Warehouse.
  • Sympathy for the Devil: He begins to empathize with the 17 Beasts after he learns the truth about them.
  • Taken for Granite: Was petrified after his final battle with Ebon and remained frozen until Nygglatho and her crew found him in the same state centuries later when all the humans have died out. It happens again at the end of the light novel series, but this time, under different circumstances and at his own behest.
  • Token Human: He’s the only human currently alive in the present day setting.
  • Tomato in the Mirror: Since he's an Emnetwiht too, it means that he's also a Beast just like the rest of his not-quite-extinct race.
  • Tragic Hero: A position he shares with Chtholly and something he seems to agree with. All he wanted was to protect the ones he loved and make them happy but including the time he was still a Quasi Brave, he believes he couldn't accomplish even that in spite of his talents. The fact that he’s eventually able to activate Seniorious, a sword which can only be used by those who can never find happiness in their lives, speaks volumes about the amount of shit he’s gone through.
  • Worf Had the Flu: As a Quasi-Brave, he's capable of many incredible feats mostly unseen by the citizens of Règles Aile. Sadly, all the curses cast on Willem 500 years ago took a toll on his body, and he can't use those abilities without risk to himself anymore.
  • "World of Cardboard" Speech: Gives a rather heartfelt one to Nils Foreigner during their last meeting where he tells his old mentor that he’s learned to let go of the past and accept his new life.
  • Would Hurt a Child: While it’s more of a Mercy Kill, he kills several of the fairies that Elpis was using to power its new weapon. They were too far gone in enroachment to be saved anyway.
  • Your Approval Fills Me with Shame: Willem felt nothing but contempt for the hilariously wicked smile that the Gremlin First Officer flashes at him when Chtholly (mistaken by the First Officer to be Willem's "secretary") introduces herself so she could join the Plantagenista expedition.

    Chtholly Nota Seniorious 

Chtholly Nota Seniorious
Voiced by: Azusa Tadokoro (Japanese), Amber Lee Connors (English)

The first leprechaun Willem meets, and the main female character for the first half of the story.

  • A-Cup Angst: The manga has a short omake where she’s shown going into a blind rage after Ithea tries to reveal her cup size to Willem.
  • Adam and Eve Plot: One of the reasons Nyglattho pitched toward Chtholly about why the latter would start training to be Willem's bride: he is the last emnetwiht, and thus he should settle down and start repopulating with a fellow markless so his race could prosper again.
  • Adorkable: Whenever she tries her hardest to catch Willem's eye only to fall short nearly every time.
    • Also, her hidden sweet tooth. Willem points out that Chtholly not wanting her sisters (especially the younger ones) to see her enjoy sweets only makes her look more childish than she wanted.
  • Arson, Murder, and Jaywalking: When Willem embraces her by surprise in the middle of Guardian Wings HQ, Chtholly complains that her spine will break, she'll suffocate, or, "worst" of all, die of embarrassment.
  • Backup from Otherworld: Willem apparently hears Chtholly calling out like she was there to join him in his "dying" moments, although he immediately dismissed it that it might have been just a hallucination.
  • Big Damn Heroes: Saves Willem and Nephren from a bunch of Timere in the final episode even as her memories of both of them are nearly completely gone at this point, at the cost of her own life.
  • Big Sister Instinct: Naturally, as the oldest leprechaun in the Warehouse, she has this towards the younger girls. Despite risking further mental deterioration from using her Venenum, Chtholly didn't hesitate at all at activating it to save Almita from getting hurt or worse from falling over from the second floor.
  • Butterfly of Death and Rebirth: Butterflies are her most common motif, not only because of her wings but also due to the transformation she undergoes over the course of the series. Much like a butterfly her life is short but beautiful. Her eventual Reincarnation as Ryehl begins the cycle of death and rebirth once more.
  • Character Shilling: In the anime, she became the object of admiration by most of the Plantaganista crew, although it's justified since she used her home skills (cooking, cleaning, etc.) to take care of them. These admirers even tell Willem that he better make sure he makes Chtholly happy, to his chagrin. And then there's Rhan and Nopht, who have so far have an issue trusting Willem, yet they are only willing to help him if it was for Chtholly's sake.
  • Child Soldier: She was born and raised to be a weapon against the Beasts, and she's been fighting them since her childhood. At the time of the series, she's only 15 years old.
  • Clingy Jealous Girl: Whenever she thinks Willem is getting a little too friendly with other girls, especially whenever Nyglattho, Nephren, and during their escort mission on the surface, Rhantolk, are concerned.
  • Cool Big Sis: As the eldest Fairy in the Warehouse, she's this to the younger girls there.
  • Crippling Overspecialization: Ithea points out that Chtholly may have been improving as a cook, but the dishes she makes caters to only one specific individual, to the detriment of the rest of the Warehouse.
  • Cruel and Unusual Death: Her body got torn apart by a combination of the Timere viciously attacking her and her overusing her Venenum when she saved Willem and Nephren. When her corpse was brought home to Nyglattho, the novels describe the state of her body as being so mangled with injuries, she was barely recognizable.
  • Curtains Match the Window: Has blue hair and blue eyes. This doesn't change even for a bit when Encroachment fully sets in, giving her a full head of red hair with red eyes to match.
  • Death of Personality: As Encroachment had begun to set in on Chtholly, bits and pieces of her memories and identity have slowly been deteriorating, effectively killing off the person who was once called "Chtholly Nota Seniorious".
  • Determinator: She's a girl with a persistent streak, though she's less hot-blooded about it than most. Best seen when she fought off the Timere in the last episode despite being fatally injured and having nearly all of her memories gone in the process before eventually dying.
  • "Do It Yourself" Theme Tune: Her VA sings the anime's opening theme song.
  • Doomed Protagonist: The anime's Cold Open spoils it, but her fate's been sealed the moment Encroachment began to set in.
  • Dying as Yourself: Her very last act as Chtholly amid her Encroachment completely destroying her memories and personality was saving Willem and Nephren at the cost of her own life.
  • Dying Moment of Awesome: She took out ALL of the Timere in the area she, Willem, and Nephren were in all by herself before she eventually succumbs to her injuries.
  • Edible Theme Naming: Her reincarnation is christened Marshmallow by Tiat and the other Fairies before she could be given a proper name. A fellow newborn Fairy like her meanwhile is called Apple.
  • Everyone Can See It: Her crush on Willem. Even Willem's not privy to this. Eventually, she doesn't even bother to hide it anymore.
  • Expository Hairstyle Change: As her encroachment sets in, her hair progressively changes from blue to red, representing her personality being subsumed by Elq's. The reason encroachment has a visible effect on Chtholly's appearance, unlike other leprechauns, is because Chtholly inherited a significantly large portion of Elq's soul.
  • Fan Disservice: The anime's opening features a nude Chtholly...bleeding horribly from a large wound in her body and getting frozen in ice from the feet up. While nothing of the sort actually happens to her in the anime, Chtholly's condition in that scene mirrors that of Elq's own state.
  • First Kiss: Willem kisses her on the lips after she falls into a coma for a second time. Not long after that she dies saving his life.
  • Foil: The so-called "happiest girl in the world" to Lillia, the "unhappiest girl in the world". She parallels Lillia in that they're both wielders of Seniorious, are both in love with Willem, and are both resigned to their tragic fates. However, their main difference lies in how they respond to their tragic situations. While Lillia hides her true emotions behind a facade of mischievousness, pride, and hot-blooded yet aloof exterior, Chtholly is much more open about her feelings, leading her to eventually find the happiness she and Lillia both sought in their lives with Willem. And while Chtholly eventually does die, she's much more successful in reaching her goals than Lillia was, who failed. Considering what we learn later on, it's heavily implied that Elq may have purposely made Chtholly this way, as part of her curiosity and desire to learn more about Lillia and how she felt when they first met.
  • Forgotten First Meeting: In episode 8 Willem realizes that she’s completely forgotten their first meeting due to the effects of encroachment.
  • Freakiness Shame: Once her hair starts to turn red, she's naturally self-conscious about it and attempts to hide it with her Nice Hat. Willem is not bothered by it at all, and even calls it pretty.
  • Freak Out: At the beginning of Episode 3, when she wakes up and remembers the embarrassing moments she's experienced the previous night (opening up a little to Willem, then the massage...).
  • Go Out with a Smile: Smiles at Willem shortly before dying.
  • Heroic Sacrifice: Dies near the end of the series, saving her friend and the person she loves from the Timere, after coming to terms that the life she once lived was a happy one in spite of her tragic fate.
  • Holding Hands: She tries grabbing Willem's hand a couple of times as a romantic gesture, but before she could eventually muster up the courage, Willem himself beats her to it.
  • Humanity Ensues: The more often a given piece of Elq's soul reincarnates into a leprechaun, the more biologically human each successive incarnation of that piece becomes as its connection to Elq weakens. It is implied that this is the reason Chtholly expressed beliefs that ran counter to the general Not Afraid to Die sentiment of leprechauns, stopped qualifying as a leprechaun biologically, and why she left behind a corpse upon her death.
  • Identity Amnesia: As the series goes on, Chtholly's personality is slowly being eroded with that of Elq's, and she slowly starts to forget who she is.
  • Imagine Spot: After Willem proposes to her, Chtholly tries to picture what her married life would be like, complete with an older Willem (she could only imagine him growing facial hair) and three kids.
  • Just a Kid: She tends to receive this treatment from Willem, much to her annoyance.
  • Living Emotional Crutch: To Willem, as he admits that she became his new reason to live after so many things that have happened to him at this point.
  • Loss of Identity: As a leprechaun, she is fated to eventually lose all remnants of her original identity and will eventually be subsumed by the Visitor Elq Hrqstn's personality, replacing her own.
  • The Lost Lenore: Her death and Willem's subsequent failure of saving her in volume 3 has affected him more than he lets on in volume 4 onward. When asked what kind of girl Willem would want to be with for life, the first person that flashed in his mind was Chtholly, saddening him.
  • Love Confession: In the novels, this occurs during the tour Phyra gives the heroes in Corna Di Luce (specifically, during their visit to the Well of Wishes and just before getting "ambushed" by the Annihilation Knights). It literally came out of nowhere that Willem was stunned and failed to get a proper response in time.
  • Meaningful Name: Her name is likely a reference to Cthylla, one of Cthulhu's offspring in eldritch mythology. In Lovecraftian lore Cthylla is supposed to reawaken Cthulhu in the event of his death. This mirrors Chtholly's role in Elq's eventual resurrection. Similarly, her implied reincarnation, Ryehl, get's her name from the sunken city of R'lyeh, the place where Cthulhu and his hordes sleep.
  • Meet Cute: No matter the hijinks they've been through together in that short time, Chtholly's and Willem's first meeting holds a special place for both of them.
  • Memento Macguffin: The blue pendant she's almost always seen wearing around her neck formerly belonged to a Leprechaun she looked up to when she was a child and who died a couple of years prior to the story.
  • Mondegreen: In their first encounter, Chtholly mistakes that Elq was looking for someone called "Jadeebo", when Elq was actually referring to her two missing Poteau, Jade Nail and Ebon Candle.
  • Nice Girl: Is very kind to strangers and is very caring to her "family" in the Warehouse. Even when she's being a Tsundere towards Willem she's still as nice as you can get.
  • Nice Hat: During her first meeting with Willem, he gives her a hat to conceal the fact that she is a featureless. She cherishes the hat very much.
  • Nice Job Breaking It, Hero!: Her Heroic Sacrifice decimated the Timere to the point where they could no longer threaten the islands for the foreseeable future. Unfortunately, this meant the Warehouse no longer had a purpose, with many in the military calling for it to be dismantled. This played right into the hands of the Elpis Mercantile Federation, which sought the fairies for its own horrific weapons program. Though in all fairness the conspiracy to take over the Warehouse was years in the making, so Chtholly’s actions more than likely just sped up their timetable.
  • No Body Left Behind: Inverted. Unlike other leprechauns, who dissolve into particles of light upon death, Chtholly leaves behind a corpse upon her death because she no longer qualified as a leprechaun biologically.
  • Not Afraid to Die: As a weapon meant to fight against the Beasts, she has been taught to just accept the fact that she would inevitably die one day in the battlefield against them, and thus, like the rest of the kids, sees no point in worrying about her injuries too much. However, her goal of making lots of happy memories before the inevitable happens seems to run counter to this belief of hers, especially after she meets Willem.
  • Not Helping Your Case: When Ithea and Nephren tried asking Chtholly about Willem's "special treatment", Chtholly's flustered refusal to divulge anything only further piqued their curiosity.
  • Not Quite Human: After her hair begins to turn red, Nygglatho medically examines her and concludes that apart from nothing being wrong with her, she doesn't even qualify as a leprechaun anymore.
  • One-Woman Army: While it eventually caused her death, she managed to completely wipe out the Timere surrounding her, Willem and Nephren all on her own without any help. She decimated them so badly that any Timere attacks after that would not happen again for very long periods of time.
  • Power Gives You Wings: Her Venenum takes the form of large blue butterfly wings behind her back.
  • The Power of Love: It was her promise to Willem (and just the thought of seeing him again) which gave Chtholly the resolve to survive the battle for the 15th island. Her sisters also speculate that it was also what allowed her to wake up from her first Encroachment-induced coma, although Ithea adds that she might have paid a terrible price for it.
  • Rapunzel Hair: Her hair extends variously from her waist to her mid-thighs in different pieces of official artwork.
  • Red Eyes, Take Warning: As Encroachment begins to set in, and with the visions from Elq growing in frequent intensity, her eyes begin to glow an ominous crimson red. Unlike most examples of this trope however, Chtholly isn't particularly dangerous to anyone but herself at this state.
  • Reincarnation: The final volume heavily implies that Ryehl, the little girl introduced in the epilogue, is Chtholly's reincarnation.
  • Replacement Goldfish: For Willem, Chtholly served as an analogue and a reminder of the two people he loved but couldn't protect the most from his past: Almaria - who shares Ctholly's motherly tendencies and close familial bond with Willem, and Lillia - Seniorious's original wielder and Willem's most trusted comrade and Implied Love Interest.
  • Retirony: She does get to retire from the front lines, however, by accompanying Willem to the surface on a mission, she still winds up dying anyway. For further irony, she's the only Fairy casualty of the mission. The other Fairies, who are all still active soldiers, managed to survive.
  • Rule of Symbolism: In order to save Chtholly, Willem goes on a mission to the surface to find the Dug Weapon Lapidemsibilus. Since Leprechauns seem to get their surnames from their Dug Weapons, it makes kind of sense for Willem to ask her to marry him when he actually finds it.
  • Secret Keeper: For Ithea after she reveals that the "Ithea" speaking to her right now was not the Ithea she knew from 2 years before. A heartwarming conversation between the two followed after they bond together during the night. Chtholly keeps her promise of not telling anybody about this secret in the end because she took it to the grave with her.
  • Sexy Secretary: After being allowed to retire, some members of the Guardian Wings Military started labelling her as Willem's assistant/secretary (which, to most of the soldiers with dirtier thoughts, also meant they are lovers). Willem seems to be the only one upset about it, while Chtholly doesn't mind the image at all, since she doesn't want to keep their relationship secret anyway.
  • She Is Not My Girlfriend: Defied. In the anime, while shopping at Island 49, a Frogman baker mistakes Chtholly and Willem to be newlyweds and offers them his sweets for a discount. Before Willem could correct him, however, Chtholly happily accepts being called his wife and the discount, to Willem's chagrin.
  • Smitten Teenage Girl: Towards Willem during their first meeting, wanting to experience what romantic love is before she would inevitably die in the front lines. It eventually evolves into genuine love the closer they grow together.
  • Star-Crossed Lovers: She is this with Willem, as she has to fight in a war against the Beasts which may very well kill her. Even if she doesn't die in battle, encroachment will eventually set in, replacing her personality and sense of self with that of Elq's, thus deleting any feelings she might have for Willem in the process.
  • Supreme Chef: She eventually becomes this through her attempts at invoking Through His Stomach.
  • Sweet Tooth: Like the rest of the girls in the Warehouse, she's one, though she'd rather not let anyone especially the little ones see her binge eating sweet stuff in public.
  • Theseus' Ship Paradox: At the end of Episode 9, with more than half of her memories gone and her sense of self being gradually replaced by Elq's due to her encroachment, she ponders if she can even be called "Chtholly" at that point.
  • Through His Stomach: She starts hogging the kitchen in Episode 7 to prepare dishes for Willem. Ithea even remarks that she is trying to invoke this trope.
  • Tomato in the Mirror: All human-sized leprechauns are actually shards of the last visitor, Elq Harkstein.
  • Too Happy to Live: She even lampshades that the only time she was ever really happy was before her death.
  • Tsundere: To Willem. At least at first.
  • You Gotta Have Blue Hair: Willem often describes it as being the same color as the sky.

    Fairy Warehouse 

Voiced by: Kikuko Inoue (Japanese), Jamie Marchi (English)

A troll who is the other caretaker at the Fairy Warehouse. She seems to love the idea of eating Willem.

  • The Ageless: Trolls are extremely long-lived and age much slower than other races. So even after a ten year time skip Nygglatho hasn’t aged a day appearance wise.
  • Beware the Nice Ones: She’s implied to have put more than a few people in the ground for threatening the Warehouse.
  • Brick Joke: One the reasons she gives for liking Willem is because she thinks he’d be able to handle her father if he ever goes on a drunken rampage. Later on Willem meets Nygglatho’s father, who tells Willem he quit drinking because his daughter kept complaining about said rampages.
  • Cute Little Fangs: Those teeth are one of the few indicators she's a troll.
  • The Dreaded: The light novels reveal that she has this reputation to the surrounding town near the Warehouse. Apparently, Willem's concerns about her cannibalistic tendencies weren't limited to only him in the past...
    • Volume 5 reveals and demonstrates just why she's this trope in said town and it is awesome.
    • The suspiciously timed death of a certain orc representing the Elpis Mercantile Federation may or may not have something to do with her.
  • Everyone Has Standards: Like almost everyone else in the Warehouse, she is a Willem/Chtholly Shipper on Deck. However, after Chtholly wakes up from her first Encroachment-induced coma, Nygglatho kicks Willem out of the infirmary when he wanted to stay by Chtholly's side as she goes back to sleep.
  • First Girl Wins: Chronologically she’s the first female character Willem meets after he’s unfrozen and she’s the one to finally welcome him home in the epilogue. The fact that he’s specifically shown reuniting with her, after she expressed romantic interest in him, strongly hints at a future relationship between the two of them.
  • Hospital Hottie: Besides her regular duties, Nygglatho also serves as the Warehouse’s nurse. In her nurse outfit she certainly lives up to the trope.
  • I Am A Humanitarian: Trolls are known to eat humanoids.
  • Important Haircut: Nygglatho cuts off and shortens her hair in a ceremony that mourns over the news of Chtholly's loss. While we aren't shown her doing this in the anime, we do see the aftermath.
  • I Want My Beloved to Be Happy: When told that Chtholly actually sees her as competition for Willem, Nygglatho neither laughs nor is offended by the suggestion, simply understanding Chtholly's feelings, with her next lines to Willem heavily implying that she wouldn't mind it if she had a man like him as her partner for life. Willem soundly rejects her and she merely accepts it.
  • Lecherous Licking: She does this to Willem in Episode 2 to tease him.
  • Mama Bear: Cares for and is protective of her young charges.
  • Maybe Ever After: When she confesses to Willem she admits that she wouldn’t mind settling down with him in another five or ten years. The fact that Willem finally does return to the Warehouse after a ten year time skip strongly hints that they may have ended up together in the end.
  • Meido: She's more of a caretaker than an actual maid, but she does dress the part.
  • My Friends... and Zoidberg: In a way that doesn't actually offend her, since she is addressed as the only non-Fairy denizen of the Warehouse aside from Willem himself.
  • Muscles Are Meaningless: She's of average build, but she's strong enough to lift up an orc more than twice her size with one hand and completely trash more of them without exhausting herself to the point of destroying the building around them nearly completely.
  • My Beloved Smother: She loves giving long bear hugs to the children under her care. Unfortunately, her embraces are strong enough to snap an actual bear’s spine.
  • Noodle Incident:
    • A run-in with a local Orc Gang known as "Black Fur", which is one of the primary reasons why she's The Dreaded. It being a Riddle for the Ages was actually invoked by Willem that he doesn't want to hear the whole story.
    • Nygglatho actually had a promising career at the Orlandry Merchants Guild, until she got on the bad side of one of its higher-ups. As a result, she was assigned to the Warehouse ever since. This was actually exploited by the Elpis Federation in order to try to get her on their side, or, failing that, just (attempt to) eliminate her.
  • One Degree of Separation: In Volume 5 she spends a lot of time worrying about Willem’s whereabouts after she hears he might still be alive. Little does she know that Willem is currently on the same island as her and working at her father’s inn no less. It’s a shame she doesn’t visit home more often.
  • Parental Substitute: Just like Willem, she's basically the Warehouse Fairies' own surrogate mother.
  • Running Gag: To Nyglattho's chagrin, Willem will never let her live down her appetite and tastes.
  • Shipper on Deck: In spite of her own feelings, she is fully supportive of Willem and Chtholly's relationship, even encouraging the latter to undergo "bride training".
  • Ship Tease: It’s very easy to pick up on the “subtext” of her desire to eat Willem. Chtholly clearly views her as her main rival for Willem’s affection. Nygglatho later confirms that she does have feelings for Willem, but prioritizes Chtholly’s happiness over her own. Still, she tells Willem that she wouldn’t mind settling down with him in 5 or 10 years time. She’s also the one to welcome Willem home after the 10 year time skip in the epilogue...
  • Silk Hiding Steel: She's beautiful, caring, and motherly...and a troll who can literally manhandle larger humanoids with ease.
  • Stepford Smiler: She keeps up a cheerful demeanor for the sake of the girls, even though she knows that she’ll probably have to send them off to die one day.
  • Supreme Chef: Is noted to be a great cook and is said to be unrivaled whenever meat is the main dish being served on the table...
  • Team Mom: Trolling aside, she's this to compliment Willem's Team Dad.
  • Troll: Often teases Willem, and threatens the children who do not do as they are told with being eaten. Bonus points for being a literal troll.
  • Underestimating Badassery: Thugs from the Elpis Federation knew that they were being sent to put a troll out of their way of taking over the Leprechauns' warehouse, but didn't even think that she could actually easily overpower them.
  • Waif-Fu: Easily manhandles orcs and other beings when they threatened her and the leprechauns.

Ithea Myse Valgulious/ Formerly "Nasania Will Pacem" (Past Life)
Voiced by: Machico (Japanese), Brittney Karbowski (English)

One of the older fairies at the Fairy Warehouse. She is partnered with the Dug Weapon,'Valgulious.'

  • The Atoner: The "current Ithea" who took over the "original Ithea" wanted to make amends to the original by continuing to live the life the "original Ithea" had without letting anybody else know.
  • Belated Backstory: The details about Ithea’s past life are only vaguely hinted at in the original light novel. The sequel eventually reveals that she’s actually Nansania Will Pacem.
  • Cat Girl: Subverted. Her hair merely looks like cat ears (Though she can still wiggle them). Her friend and fellow Leprechaun Nephren can brush her hair into this shape.
  • Chekhov's Gunman: When she tells Rhantolk about her encroachment she also mentions that she wielded the dug weapon Pacem in her previous life. This detail becomes relevant in the sequel Suka Moka.
  • Cry Cute: The first time was during episode 9 when she and Chtholly had a Friendship Moment with each other. The second time was when she was mourning over the loss of her two closest friends, Chtholly and Nephren, the former of which was confirmed dead while the latter is missing in the final episode.
  • Cute Little Fangs: Like with her cat ear-shaped hairstyle, it's part and parcel of her cat motif.
  • Dark and Troubled Past: In her past life Nansania lived through some of the worst events in the floating islands’ history before dying in a nightmarish battle with her former best friend. And this was all before she replaced the previous Ithea.
  • Dead Person Impersonation: In a way. The "original Ithea's" personality had already been completely subsumed after she experienced encroachment two years prior to the events of the story, so the "current Ithea", out of guilt, decided to read up on all of Ithea's diaries to effectively become her again, hoping to make up for the loss of the original's identity. Until she told Chtholly this, no one actually caught on to it.
  • Death of Personality: The original Ithea had already been long gone, thanks to Encroachment.
  • Death Seeker: She initially considered suicide after she replaced the original Ithea, but decided against it. Later on she still shows a notable lack of concern for her own life, especially after Chtholly’s death.
  • Foreshadowing:
    • During a routine health checkup the doctor recommends not pushing herself in combat, because her degraded physical state means that she can no longer recover from serious injuries. Not long after that Ithea is permanently crippled.
    • Chtholly figures out that Ithea has already undergone Encroachment since she knows a lot about the subject, and eventually confronts Ithea about it.
  • The Gadfly: She enjoys teasing others, particularly Willem and Chtholly.
  • Game-Breaking Injury: The final battle of the series leaves her permanently wheelchair bound.
  • Imaginary Love Triangle: She mistakes a somber moment between Willem and herself for him coming on to her, and even thinks there's a romantic atmosphere. Willem had to remind her that the two of them are not alone, carrying a fatigued Chtholly on his back, so Ithea changes her mind and thinks that a love triangle is about to ensue between them when Chtholly wakes up.
  • Irony: She is unconcerned with the possibility of dying in combat to the point of being a Death Seeker. Contrary to her expectations, however, she ends up permanently crippled and is forced into retirement; ensuring that she’ll likely outlive most of her fellow fairies.
  • Mood Whiplash: When the three Fairy Soldiers are discussing their first impressions of Willem, it becomes serious when Ithea suddenly asks Chtholly how many days she has left...and then snaps right back to a melancholy mood when Ithea ponders if it's enough time for Chtholly to pursue a relationship with Willem.
  • Older Than They Look: She originally died when she was 18 years old in her previous life and has been living as “Ithea” for the past four years. So technically she’s 22 but presumably continues to act like a 14-year-old girl in order to keep up her facade.
  • Power Gives You Wings: Like Chtholly and Nephren, her Venenum takes the form of giant butterfly wings that allow her to fly, hers being a golden orange in color.
  • Rapunzel Hair: In the sequel novels when she's older her hair reaches up to her legs.
  • Romantic Wingman: For Chtholly, encouraging the girl to be more forward with her feelings for Willem.
  • She's All Grown Up: In Suka Moka.
  • Shipper on Deck: The most vocal supporter for Willem x Chtholly, even acting as Chtholly's wingman at times for her. Chtholly actually invoked this in Ithea, claiming that, once they return from the battle for the 15th island and Chtholly confronts Willem with her feelings, she expected Ithea to have her back and support Chtholly all the way, which she does.
  • Stepford Smiler: Never puts down her smile to keep up her facade. She even lampshades it herself.
    Ithea: A cheery busybody who kept sticking her nose in other people's business but never revealed her own true feelings. That's the kind of girl Ithea Myse Valgulious was.
  • Survivor's Guilt: Starts to show shades of it when both Chtholly and Nephren are declared KIA.
  • Thinks Like a Romance Novel: In the Light Novels, she is a huge fan of romantic novels, explaining why Ithea is so well-versed in romantic clichés. However, hearing the title of one of her favorite works, Willem plans to confiscate them because he believes they are inappropriate for her age. It is later revealed that the "original Ithea" is in fact an aspiring novelist, further explaining this Hidden Depths aspect to the "current" Ithea.
  • The Un-Reveal: For the anime at least. The "current" Ithea finishes her confession to Chtholly with asking the latter if she wants to know her true name. Chtholly tells Ithea that her true name doesn't matter, because to her, Ithea is still Ithea regardless of Encroachment.
  • Verbal Tic: Tends to add "-su" before she ends her sentences in the original Japanese dub.
  • Zettai Ryouiki: Wears a Grade A with her usual outfit and her military uniform.

Nephren Ruq Insania
Voiced by: Akari Uehara (Japanese), Alexis Tipton (English)

One of the older fairies at the Fairy Warehouse. She was partnered with the Dug Weapon,'Insania.'

  • The Ageless: After becoming a half-Beast. Even after five years have passed between the ending of Suka Suka and the beginning of Suka Moka, Nephren hasn't aged a day compared to the other Warehouse leprechauns.
  • Badass Bookworm: Usually spends her free time reading.
  • Brainwashed: Odette used her cursed eyes on Nephren at some point after Island 2 was attacked. It is currently unknown what she plans to use Nephren for.
  • The Bus Came Back: She eventually returns in the fifth volume of the sequel.
  • Clingy Jealous Girl: She literally clings to Willem after he hugged Chtholly in episode 4. She also makes it damn clear to Elq that she’s the only one who can snuggle up next to Willem.
  • Comforting Comforter: A rare example where she uses herself as the blanket for Willem to warm him up whenever they both go to bed. And it's not limited to sleeping on top of his body either.
  • Covert Pervert: She really wanted Willem to tell her about the time he fought a succubus. Then there’s her favorite method of getting Willem’s attention: pinching him in the rear.
  • Cuteness Proximity: Towards a newly-revived Elq.
  • Deuteragonist: Following Chtholly's death at the end of volume 3 where the anime ended, she ascends to this status in volumes 4 and 5 in the light novel series as she gets a heaping ton of focus and development in said volumes next to Willem.
  • Emotionless Girl: Tries to play herself off as this, but subverted in that she has emotions, she just doesn't show them often.
  • Eyepatch of Power: Wears one in the fifth volume to cover her now golden left eye to keep her Beast half in check.
  • Girlish Pigtails: To emphasize her youth and the fact that she's the youngest of the older leprechauns.
  • Half-Human Hybrid: After she and Willem absorb Shiantor, she's effectively become half-Beast.
  • I Want My Beloved to Be Happy: She realizes that although it would be very easy to revive Willem, doing so would only result in him returning as a beast. Even though she herself is now also part beast, she knows that Willem would not want to be brought back as something that could threaten his loved ones. So in spite of her strong desire to be with him, she opts to keep him in his deathlike state rather than cause him unnecessary suffering.
  • In-Series Nickname: Ren.
  • Irony: She was born as a leprechaun fated to die at an early age fighting against the 17 Beasts. Which makes it bitterly ironic when, she becomes an immortal half-beast.
  • Little Miss Badass: She's the shortest and the youngest of the Fairy Soldiers (i.e., the older Fairies in the Warehouse), but she can fight just as well as her comrades can.
  • Living Emotional Crutch: Like Chtholly, she's this to Willem, promising to always be by his side so "he wouldn't break".
  • Mismatched Eyes: After becoming half-Beast, Nephren now has a golden left eye.
  • Mistaken for Romance: More than one character has come to the conclusion that her attachment to Willem is not so platonic after all. The light novel leaves things pretty ambiguous. There are some hints that she harbors a one-sided crush on Willem, but she never admits this.
  • Mystical White Hair: Her hair is a shade of white despite being only around Ithea and Chtholly's age. Justified as she's a leprechaun like they are.
  • Normally, I Would Be Dead Now: She is unsure how an average fairy like herself managed to survive everything that happened in volumes 3 and 4.
  • Not So Above It All: See Clingy Jealous Girl and Covert Pervert. Also, showing awkwardness when Nopht starts talking about Chtholly like she has passed away just as Chtholly walks up to Nopht.
  • Not So Stoic: Starts to show a more vulnerable side as the series progresses. It really shows when she reunites with Willem in volume 5. She's practically crying tears of joy.
  • Older Than They Look: She still looks the same as she'd been in Suka Suka during Suka Moka's events despite five years having passed between the two series. It's likely a result of her becoming immortal after being turned into a half-Beast in the ending of Suka Suka's 4th volume.
  • O.O.C. Is Serious Business: When Ren calls Willem out on what she believes is him shirking from his promise to Chtholly, she says it outright that she will also get mad at him herself.
  • Power Gives You Wings: Like her two friends before her, her Venenum takes the form of a pair of butterfly wings, with hers being colored violet and lavender.
  • The Promise: An ailing Almaria extracts a promise from Ren to watch over Willem, a request that Ren intends to keep, no matter the consequences.
  • Put on a Bus: She’s absent for most of the sequel.
  • Red Eyes, Take Warning: In the final two episodes, her eyes begin to glow red just like Chtholly as Encroachment is beginning to take its effect on her. It and its aftereffects disappear completely however after Chtholly reverses it, taking it with her to her grave.
  • Spanner in the Works: Her appearance 500 years in the past is Willem’s first clue that he’s trapped in a Lotus-Eater Machine. Indeed it’s likely that Shiantor unintentionally trapped her in its illusion while targeting Willem. If it weren’t for that Willem might have easily fallen for the temptation of becoming permanently trapped in a delusion of his former life.
  • The Stoic: Rarely emotes and is always displaying a calm and unemotional demeanor.
  • Sugar-and-Ice Personality: She rarely displays any outward emotion.
  • Superpowered Evil Side: Her half-Beast nature is basically this to her as, whenever she opens her golden left eye, she'd hear voices in her head ceaselessly encouraging her to destroy.
  • Synchronization: She was somehow able to sense Willem's Heroic Suicide even though she's on the 2nd island and he's on the 11th. This may have something to do with how they are both possessed by Shiantor.
  • Two Beings, One Body: After her and Willem's encounter with the beast Shiantor.
  • Undying Loyalty: She rivals Chtholly in this, but she's very attached to Willem in a platonic manner and is usually seen being by his side most of the time.
  • When She Smiles: No one comments on it much, but she's pretty adorable when she flashes a smile, especially when you take into account that she's The Stoic one in her team.
  • You Can't Go Home Again: After becoming half-Beast, Nephren can no longer return to the Warehouse in fear of what might happen should anyone outside Nyglattho and a few others know that a Beast is being allowed to live in one of the islands.
  • You Remind Me of X: After attracting the admiration of most of the boys from Willem's orphanage, Ren compares their energy to that of Collon's.

Rhantolk Ytri Historia
Voiced by: Kazusa Aranami (Japanese), Leah Clark (English)

  • A-Cup Angst: While she isn't flat by any means, she was annoyed when Ithea implicitly pointed out that Rhan wasn't endowed with enough flesh around a certain area in her body while her eyes casually glanced at Rhan's chest.
  • Adorkable: Underneath her cool exterior lies an awkward dork whose internal thoughts are unbecoming of someone of her demeanor. Most prominent in volume 5 where the readers get to see things from her point of view.
  • Always Someone Better: After returning from her journey, she feels everything she does is overshadowed by Willem's achievements.
  • Badass Bookworm: Is always seen reading books during her spare time, and could even crudely translate Emnetwiht writing - a lost language as of the series' timeline - on her own with no outside help. Being one of the Fairy Weapons in the story, she's also capable of putting up a fight against the Beasts with her own Carillon, Historia.
  • Does This Remind You of Anything?: Her...moans while Willem's giving her his special massage to alleviate her pressure points from venenum poisoning are pretty highly suggestive. The music in the background really doesn't help her case.
  • Hypocritical Humor: Calls Willem's massage "fishy"...coming from the girl who had the dodgiest reaction to it so far.
  • Ice Queen: Towards Willem, being the girl who took the longest to warm up to him even by just a little, mostly due in part of him being an Emnetwiht.
  • In-Series Nickname: Rhan.
  • Lady of War: Her movements are noticeably more refined in combat compared to the other Leprechauns. Appropriately enough, her Historia is roughly in the shape of a rapier.
  • Meaningful Name: Her last name is reflective of her general interest in the history of the world.
  • Power Gives You Wings: Like with the others before her, her Venenum takes the form of purplish-blue butterfly wings on her back.
  • Proper Lady: Of the Leprechauns seen so far, she is the most ladylike, with her mannerisms having a touch of elegance and grace in them.
  • Red Oni, Blue Oni: The blue to Nopht's red, being the calmer and quieter of the two. Amusingly, her hair is blue while Nopht is a redhead.
  • Secret Keeper: Ithea eventually confides with Rhan about her own Encroachment.
  • She's All Grown Up: She grows to become a beautiful young woman in Suka Moka.
  • The Stoic: While much more expressive than the quieter Nephren, Rhantolk is nonetheless very calm and introverted, rarely raising her voice even when angry.
    • Not So Stoic: Her Big Sister Instinct was on when Willem was performing his special Venenum massage on Nopht, immediately demanding that Willem unhand her even though he wasn't doing anything remotely harmful to her. Of course, when it's her turn afterwards...
  • Tomboy and Girly Girl: Is the girly girl to Nopht's tomboy, being the more feminine of the two.
  • Vitriolic Best Buds: It's only briefly mentioned in passing in the light novels, but she monologues that while she didn't always get along well or particularly like Chtholly all that much, she did care for her a lot.
  • You Are Better Than You Think You Are: She tries to comfort Willem after his Despair Speech by telling him that although he couldn’t save Chtholly, he at least was able to make her short life meaningful.
  • Younger Than They Look: In spite of her cool demeanor and figure, she's actually Chtholly's one-year junior instead of the other way around.

Nopht Keh Desperatio / Nopht Caro Oracion
Voiced by: Inori Minase (Japanese), Felecia Angelle (English)

  • Big Sister Instinct: She can be very protective of her younger “sisters”.
    • She attacks Willem during their first meeting because she mistakenly assumed he was a creepy pedophile trying to perv on Nephren.
    • A far less humorous example is when she almost kills Feodor in a fit of rage for "abducting" Lakhesh. In this case she was also mistaken, though she didn’t realize her error till after Lakhesh showed up and beat the shit out of her.
  • Boyish Short Hair: See her image to the right. It's easy to mistake her for a boy when you're unaware that all Leprechauns are always female. She eventually grows it out.
  • Chekhov's Gun: Her Carillon Desperatio is a "kinslayer-type" weapon, meaning that it was made specifically to kill off the wielder's same kin. Willem finding nothing wrong with it despite Nopht using it against Beasts and not Emnetwihts as it was supposed to be used against is the final confirmation Willem needed to confirm that the Beasts were indeed the humans.
  • Dynamic Entry: Nopht "introduces" herself to Willem by dive-kicking him from the back. Nopht remains standing on top of Willem as he lay sprawled face-first on the ground for a while.
  • Girliness Upgrade: While she still has a tomboyish streak, she's developed a much more female figure in the sequel. With her long hair and well defined "assets" no one is going to be mistaking her for a boy anytime soon.
  • Hot-Blooded: Has an impulsive streak and is much more gung-ho when it comes to fighting.
  • Lightning Bruiser: Her first onscreen fight against the Beasts shows her to be a terrifyingly fast fighter on the field, taking out a gigantic Timere in a few mere seconds in a series of fast slashes. When Feodor fights her he is barely able to keep up with her movements due to that speed.
  • My God, You Are Serious: She initially laughs at Feodor’s claim that he only wants to help the Leprechauns by preventing the military from using them as weapons. She stops when she realizes that he’s dead serious.
  • Please Don't Leave Me: Gives a variation of this to Chtholly just as she's fully succumbed to Encroachment and is about to jump off the ship with Desperatio in hand to save Willem and Nephren. Nopht tries to plead with Chtholly not to go out and fight anymore as she no longer qualified as a Leprechaun and that the rest of them can fight her share, but Chtholly still goes off after a final farewell to Nopht anyway.
  • Power Gives You Wings: Just like her Fairy comrades, Nopht's Venenum takes the form of red butterfly wings.
  • Red Oni, Blue Oni: The red to Rhantolk's blue, being the more boisterous and impulsive one between the two. Interestingly, Nopht's hair is red while Rhan's hair is blue.
  • Right Behind Me: In their reunion on the surface, Nopht asks Ren about Chtholly, thinking she died on the battle for the 15th island as predicted, and immediately gets startled when the girl in question calls her name. Chtholly winds up chasing after Nopht (the latter thinking she's seeing a ghost) trying to explain what really happened until they exhausted themselves.
  • She's All Grown Up: While just as tomboyish as ever, Nopht grows to have a more feminine figure in the sequel series, Suka Moka
  • The Squadette: Being the most tomboyish of the Leprechauns shown so far added with her being a member of the military just like the other Fairy Soldiers, she's this. In the epilogue, even though the Fairies are now allowed to live normal lives, Nopht still chooses to enlist in the military.
  • Tomboy and Girly Girl: The tomboy to Rhantolk's girly girl.
  • Vitriolic Best Buds: She has a short line where she admits that she and Chtholly didn't always see eye to eye, but like Rhan, ultimately did care for Chtholly's well-being and happiness, as seen when she mourns over Chtholly's supposed death from volume 2's battle before Chtholly herself shows up right behind her. At the end of the anime, she even rants about Chtholly's death in the aftermath of volume 3's climactic battle, not understanding, or at least, not accepting, Chtholly's decision and final speech to her after Nopht pleads for her not to march to her death.
  • What Happened to the Mouse?: She loses Desperatio after Chtholly uses it during her Heroic Sacrifice. Somehow Desperatio is never found again even though it was explicitly stated that Chtholly's corpse was safely returned home. Without her Dug Weapon, Nopht was forced into retirement ever since.
  • Worf Had the Flu:
    • Nopht may have had a better chance in stopping Chtholly from performing her Heroic Sacrifice if it weren't for the many injuries she sustained during the airship battle.
    • In Volume 5, because of the loss of Desperatio, Nopht has to stay behind the Warehouse and look after the younger Fairies and thus is left out of the final battle of Suka Suka.

    Younger Leprechauns 

Pannibal Nox Katena
Voiced by: Yurika Kubo (Japanese), Sarah Wiedenheft (English)

A young purple-haired Leprechaun and the second one Willem meets. She is a minor character at first, but becomes one of the main characters in Suka Moka.

Tiat Siba Ignareo
Voiced by: Tomomi Mizuma (Japanese), Lara Woodhull (English)
A young green-haired Leprechaun who lives at the Fairy Warehouse. She is a minor character in Suka Suka, but becomes one of the main characters in Suka Moka

  • Adorkable: This is usually the result whenever she geeks out over movie trivia. It even applies in-universe when she sees a sign at the Lovers' Staircase that read "No Rolling!", and she screams like she reached her Despair Event Horizon. Nearby onlookers are amused by her reaction.
  • Afraid of Needles: She vehemently denies it while there are tears in her eyes after her medical check-up though.
  • All Girls Want Bad Boys: Her Love Interest has some rather dubious morals and beliefs.
  • Always Second Best: She lags behind her peers in nearly every category in spite of her desire to become a legendary fairy soldier. This has led to her developing something of an inferiority complex in the sequel.
  • Anger Born of Worry: Feodor is frequently on the receiving end of this.
  • Ascended Extra: She becomes the main heroine of the sequel series, Suka Moka, set a couple of years after the ending of Suka Suka following Chtholly's death.
  • Bait-and-Switch: In the sequel readers are initially inclined to believe that her role in the story will be very similar to Chtholly’s. In reality, Lakhesh ends up inheriting Chtholly’s mantle of Tragic Hero.
  • Big Sister Instinct: As the oldest of the children in the Warehouse, she takes care of the younger leprechauns whenever either Nyglattho or any of the fairy soldiers (i.e., the older leprechauns) are absent.
  • Big Sister Worship: Towards Chtholly. Deconstructed in the sequel where it’s shown that this mindset has led to more than a few negative traits.
  • Break the Cutie: The events of Suka Suka and the ensuing 5 year Time Skip have left a noticeable impact on her. Much like Chtholly, she’s resigned to an inevitable death when Feodor first encounters her.
  • Broken Bird: She’s a far cry from her carefree younger self at the start of Suka Moka.
  • Contrasting Sequel Main Character: Despite her many obvious similarities with Chtholly, Tiat actually turns out to be a quite different character. Unlike Chtholly, Tiat actually wants to be a Tragic Hero, but can’t due to being The Unchosen One. This desire actually puts her closer in character to Willem during his quasi brave years.
  • Child Soldier: She became a fairy soldier when she was only ten years old.
  • Cry Cute: She has a tendency to tear up while looking absolutely adorable.
  • A Day in the Limelight: Most of episode 4 centers around her and Willem.
  • Death Seeker: She definitely shows signs of this in the sequel.
  • Does This Remind You of Anything?: When Feodor first meets her, she’s sitting on a ledge with a depressed look on her face. The implications aren’t lost on him.
  • Don't You Dare Pity Me!: She reacts harshly to Feodor’s suggestion that the Leprechauns deserve better than their current lot.
  • Et Tu, Brute?: Finding out that Feodor had betrayed the military was bad enough for her. However, this was nothing compared to the Heroic BSoD she went through after she discovered that Lakhesh was aiding him.
  • Fake-Out Make-Out: Her First Kiss happens, because she was trying to help Feodor avoid being spotted by a patrol. They just so happened to be in front of Corna Di Luce’s most famous romantic landmark, so they end up embracing like the many other pairs of young lovers in the plaza. Their fake embrace quickly turns into a real one and they end up passionately kissing in the heat of the moment.
  • Fangirl: A big one for romantic movies. Her reaction when she and Willem toured around Corna di Luce, the site of many movies, can be summed up to "Squee!".
  • Freudian Excuse: Her cynical outlook in the sequel isn’t too surprising considering what happened to Willem and Chtholly. Tiat greatly looked up to Chtholly and she died an extremely tragic death. Willem was the closest thing she ever had to a father and she ended up being one of his unwilling executioners after he turned into a Beast.
    • This likely explains why she’s such a huge Shipper on Deck for Feodor and Lakhesh, because she sees them as possible replacements for Willem and Chtholly. She strongly encourages Feodor to move to the Warehouse with Lakhesh once everything is finished on Island 38; suggesting that she wants them to fill the roles once held by the afformentioned individuals.
  • Generation Xerox: Chtholly tells Willem that Tiat's dedication to look out for the younger Leprechauns reminded Chtholly of herself back when she was taking care of Tiat.
  • I Just Want to Be Special: Her primary goal in life is to grow up to be a legendary fairy soldier like Chtholly. Ironically she’s at best an average fairy with an unexceptional dug weapon. Willem thinks this is a good thing, because average people don’t meet tragic fates.
  • I Meant to Do That: Despite Feodor’s warnings she falls off a ledge and into a retaining pond. After he drags her out she insists that she was just trying to go for a swim.
  • Implied Love Interest: Feodor is unable to give a yes or no answer when asked if he was romantically involved with her.
  • Inadequate Inheritor: Much of Tiat’s insecurity comes from her perceived failure to live up to Chtholly’s legacy.
  • Inferiority Superiority Complex: Her goal of becoming a legendary fairy soldier has led to her developing a crippling inferiority complex in the sequel due to her lack of natural ability.
  • Insecure Love Interest: Her feelings of inferiority are one of the reasons why she’s slow to admit that she’s fallen in love with Feodor.
  • I "Uh" You, Too: Her promise to “arrest” Feodor following their ecounter at the Great Sage’s statue sounded awfully like a Love Confession.
  • Just a Kid: She hates being treated like a kid, especially after she becomes a full fledged fairy soldier.
  • Marked to Die: Tiat is revealed to be originally slated to die and disposed of, by opening her Fairy Gate during the Battle with Croyance at the end of Suka Moka Chapter 1. She survives of course.
  • Match Maker Crush: She initially wants to set Feodor up with Lakhesh, because Lakhesh is the only one of the four fairies not scheduled to die in the upcoming battle with Croyance. She hopes that Feodor will help Lakhesh fill the void left by her friends’ inevitable deaths. Needless to say, she soon starts to fall for Feodor as well, quickly turning the whole affair into a Love Triangle.
  • Memento Macguffin: After Chtholly's death, she's seen wearing on her person the same blue pendant Chtholly used to wear on herself, which just so happened to also be a memento from a senpai Chtholly looked up to when she was younger. This can also be seen as Chtholly passing on the torch to Tiat as Tiat herself becomes the main heroine of the sequel light novel series years later following Chtholly's death.
  • Not So Different: Both she and Feodor grew up idolizing an older sibling figure, who helped shape their respective world views. Their feelings of inadequacy at living up to the ideals of those figures has led to both of them developing extremely negative views of themselves.
  • Pint-Sized Powerhouse: Once she's given the Carillon Ignareo, as shown when she used it against a transformed Willem in volume 5.
  • Power Gives You Wings: Her venenum takes the form of light green butterfly wings.
  • O.O.C. Is Serious Business: Tiat is a bit of a Tsundere, which makes it odd that she didn’t slap Feodor after he kisses her in the middle of a public plaza. Instead she playfully pokes him on the chest, suggesting that she was more open to their brief romantic encounter than he thought.
  • Running Gag: On more than one occasion she trips and falls off the roof of the abandoned theatre on Island 38.
  • Sacred First Kiss: Feodor feels guilty about “stealing” this milestone from her in order to save his own skin. Tiat actually doesn’t seem too upset by this.
  • She's All Grown Up: She’s a teenager by the start of Suka Moka.
  • Ship Tease: With Feodor.
  • Slap-Slap-Kiss: Due to Feodor’s status as a borderline Villain Protagonist, she often finds herself at odds with him. This doesn’t stop her from developing romantic feelings for him. In fact she seems determined to use their relationship to steer Feodor down a less extreme path.
  • Spanner in the Works: A lighter, almost-comical example than most, but Tiat's excitement at seeing Chtholly awake again (after thinking that the latter completely succumbed to Encroachment) ruins Chtholly's attempts to eavesdrop on Willem pouring his heart out (thinking he failed to deliver on his promise to her).
  • Suspiciously Similar Substitute: For Chtholly.
  • Suspiciously Specific Denial: Loves doing this every time she either screws up or when a "weakness" of hers comes to light.
  • The Triple: After the incident with Phyra, Tiat is just as angry at Willem as her seniors were: while with Chtholly, Nephren and Ithea it was because of an apparent slight Willem didn't even know, Tiat is angry...because she didn't get to see more of Corna di Luce.
  • Tsundere: She’s definitely more of a Tsundere than Chtholly ever was. It also doesn’t help that she and Feodor butt heads much more than Chtholly and Willem ever did.
  • Uncanny Valley: In the sequel, she is described as having almost doll-like features that make one question if she’s even alive. It’s enough to seriously unsettle Feodor. Fortunately, she manages to liven up a bit when he starts talking to her.
  • The Unchosen One: This is the reason why she can only use a low-level dug weapon.
  • Underestimating Badassery: Averted. She came fully geared up for battle when she first confronted Feodor about his true allegiances. She just wasn’t expecting him to disarm her using one of Willem’s fighting techniques. She recovered just in time for Lakhesh to show up...and promptly side with Feodor.
  • Walking Spoiler: Her outfit in Suka Moka essentially spoils the fact that Chtholly dies at some point in the original series.
  • You Gotta Have Blue Hair: Green in her case.

Collon Rin Purgatrio
Voiced by: Hina Kino (Japanese), Kristi Rothrock (English)
A young pink-haired Leprechaun who lives at the Fairy Warehouse. She is a minor character at first, but becomes one of the main characters in Suka Moka.

  • Break the Cutie: She turns into a sobbing wreck after Lakhesh declares her utter hatred for her former sisters and promptly deserts the military.
  • Genki Girl: She's a very hyperactive kid whose cheerfulness defines her.
  • Innocently Insensitive: In spite of Lakish's warnings, she blabs about Willem and Ren "sleeping together", which instantly upsets Chtholly.
  • Marked to Die: Collon is revealed to be originally slated to die and be disposed of, by opening her Fairy Gate during the Battle with Croyance at the end of Suka Moka Chapter 1. She survives of course.
  • Muscles Are Meaningless: During training, she easily manhandles soldiers from the 5th Division in spite of her small stature.
  • No Sense of Personal Space: She loves to jump on Willem's back and lock her arms and legs around him. It was commented on by others that her weight alone was painful enough for him. She does the same thing to Feodor Jessman causing him to scream out in pain until Lakhesh saves him.
  • Please Don't Leave Me: Pannibal initially tries to go after Lakhesh following the latter’s desertion. Collon, not wanting to be left alone after the traumatic incident they’d just witnessed, stops her from leaving.
  • Rapunzel Hair
  • Rose-Haired Sweetie: Has pink hair and is very friendly.
  • Saved by Canon: She’s mentioned in Suka Suka’s epilogue, which takes place five years after the events of Suka Moka. This means that she’s the only one of the four main female characters who will definitely survive the sequel.
  • She's All Grown Up: In Suka Moka

Lakhesh Nyx Seniorious
Voiced by: Manaka Ishimi (Japanese), Jill Harris (English)
A young orange-haired Leprechaun who lives at the Fairy Warehouse. She is a minor character at first, but becomes one of the main characters in Suka Moka.
  • The Ace: Lakhesh easily outclasses her peers in terms of raw ability.
  • All Just a Dream: The EX sidestory's Framing Device is implied to be a dream Lakhesh had while lying next to Seniorious.
  • Apologizes a Lot: Even if it isn't her fault in the first place.
  • Became Their Own Anti Thesis: Her personality does a complete 180 after Elba takes over. Although Elba and Lakhesh may look the same, with the former even continuing to use the latter’s name, their personalities could not be more different.
  • Beware the Nice Ones: She’s one of the sweetest girls you’ll ever meet. But DO NOT get on her bad side. Nopht found this out the hard way.
  • Break the Cutie: Lakhesh suffers many breaking moments over the course of the two novels series. Her first act as Fairy Soldier is to kill the man who, even if for a short time, she happily called her father. That she inherited Seniorious means that it is only the first of the tragedies she's going to face in the future. Then in Suka Moka, she not only goes through Mental Disintegration, she gets her body hijacked by her past life and she ends up being controlled by Vincra: The Fourteenth Beast.
  • Brooding Boy, Gentle Girl: She's one of the few people Feodor is actually willing to open up to.
  • Chekhov's Gunman: Her first day as a fairy soldier is also the day of the attack on Corna di Luce. Her unexpected arrival with Seniorious is the only reason the fairies are able to win against Willem.
  • Child Soldier: She became a full fairy soldier at age nine and was forced into combat on her first day.
  • Contrived Coincidence:
    • In order to act against the Elpis Federation's attempts of seizing power, Nyglattho was issued with a summons to come to Corna di Luce with several fairy soldiers for a secret meeting. Nyglattho had to think up an excuse for them to show up on the island without attracting too much attention, and Lakhesh comes up and tells her about her dream (the symptom that indicates a Fairy is ready to be tuned into a soldier), giving them a good cover story for coming to the island after all.
    • Apart from the Dug Weapons that have registered users, Nyglattho also brought one weapon without a master yet. That very weapon would actually be what Lakesh would be compatible with (especially compared to Tiat, who was described as having taken a long time to find a compatible weapon). Unfortunately, for Lakesh, that weapon happens to be Seniorious.
  • Cosmic Plaything: Her entire life spirals into tragedy after she becomes the user of Seniorious.
  • Cry Cute: Might as well be her default expression.
  • Death of Personality: Her personality fragments due to venenum overuse. Those fragments mix together with memories of her past life as Elba to form a new identity. While it’s clear that Lakhesh isn’t completely gone, Elba now appears to be the dominant personality in their body.
  • Deuteragonist: She arguably shares the role of main heroine with Tiat in Suka Moka.
  • Doom Magnet: Clearly the universe has had it out for Lakhesh ever since she became the user of Seniorious. Where Lakhesh goes, disaster and tragedy typically follows.
  • Expository Hairstyle Change: Elba notably ditches Lakhesh’s side ponytail when she takes over the latter’s body. Her new look not only symbolizes her new personality, but also Elba’s lack of her former self’s childlike innocence.
  • Grand Theft Me: Her body gets taken over by Elba in volume 3 of the sequel. Though Elba didn’t technically steal it; she just moved into the void left by Lakhesh’s former personality.
  • Irony: She’s the only fairy in the Island 38 group not scheduled to die in the upcoming battle with Croyance. It is therefore bitterly ironic that the person known as ”Lakhesh Nyx Seniorious” is the first to “die” due to her venenum induced Death of Personality.
  • Mistaken for Romance: More than one character comes to the conclusion that she and Feodor are a couple. One of those people is Lakhesh herself after her body gets taken over by Elba. The “new” Lakhesh becomes convinced that her own feelings for Feodor stem from the “original” Lakhesh. This leads to an awkward moment between the two when she attempts to continue what she sees as their former relationship.
  • O.O.C. Is Serious Business: She’s normally a soft-spoken shy girl. Which is why you know things have gotten bad when she gets PISSED. It happens in Suka Moka and it’s not just some little blowup either. At one point she PHYSICALLY ASSAULTS Collon and rips out a clump of her hair, forcing Pannibal to step in and prevent her from doing worse. It’s one of the first signs that she’s no longer “Lakhesh”.
  • Pint-Sized Powerhouse: After she gains Seniorious as her weapon. She's also the one who got to deal the "killing blow" to a transformed Willem.
  • Staking the Loved One: She’s forced to stab Willem with Seniorious in a Mercy Kill in the climax of Volume 5.
  • She's All Grown Up: Like the other girls she’s a teenager by the start of Suka Moka.
  • Ship Tease: She has a considerable amount with Feodor in the sequel.
  • Shrinking Violet: Is the most soft-spoken of the named younger leprechauns and is the shyest to boot.
  • Split Personality: Her personality fragments due to encroachment, causing memories of her past life as Elba to resurface.
  • Thinks Like a Romance Novel: After going to see a romantic movie she expresses a desire to also be in love one day.
  • Walking Spoiler: Knowing her last name spoils the fact that she receives Seniorious as her weapon after Chtholly's 'death'.

    Island 38 

Feodor Jessman

An ambitious young Imp serving as a 4th Grade Officer in the 5th Division of the Guardian Wings Military.

  • Anti-Hero: On the surface, he's a very self-serving individual who will do anything for his own personal gain. However, he does have a heroic side to him that he seldom acknowledges.
  • Arson, Murder, and Jaywalking: During his time on Island 38 he sneaks into restricted areas, steals the most powerful dug weapon in the military's arsenal, and skips training in order to go buy donuts.
  • Awesome, but Impractical: His cursed eyes are pretty damn impressive when they actually work; allowing him to effectively bend the target to his will. Unfortunately, it only has a ten percent success rate and only works on races that are closely related to humans. Not to mention all the other myriad requirements for its successful use.
  • Becoming the Mask: Intitially he only wants to get close to the Leprechauns so that he can manipulate them into aiding his plans. However, he eventually comes to care for the girls and begins to focus his efforts on saving them.
  • Berserk Button: When Pannibal threatens to reveal his various illegal activities he ends up going into an almost animal like rage in which he nearly considers murdering her to keep his secret safe.
  • Boomerang Bigot: He has a very negative view on disfeatured races in spite of being one himself.
  • Byronic Hero: Feodor is a classic example of this trope. He is an extremely cunning and charismatic individual, who also has deep personal flaws that he struggles with. His beliefs are far outside “mainstream” society, but he remains committed to them nonetheless. He is also more than willing to carry out immoral acts to achieve his goals, which he believes are for the greater good.
  • Consummate Liar: Lying comes very easily to him and he’s more than willing to tell half truths to avoid difficult situations.
  • Contrasting Sequel Main Character: Is the complete opposite of Willem in terms of background. He comes from a noble family and has lived on the islands his entire life, unlike his predecessor who grew up in a poor orphanage 500 years ago. He also lacks many of Willem's moral scruples and is much more self-serving.
  • Covert Pervert: Being tasked with looking after a group of teenagedgirls puts an obvious strain on his model soldier facade. His internal dialogue makes it blatantly obvious that he’s lying when he says that he has no interest in them sexually. Of course when it comes to his love of Cat Girls he completely averts this trope and openly admits to preferring women with cat features. Even Nax Selzel is slightly creeped out by this.
  • Crouching Moron, Hidden Badass: He normally acts like a craven imp who wants nothing more than to save his own hide. This all serves to hide the fact that he’s an extremely skilled fighter who can easily take on opponents much stronger than himself.
  • Dark and Troubled Past: He’s from the Elpis Mercantile Federation and lost most of his family when their experiments with the 17 Beasts destroyed Island 13. To make matters worse, his own brother in law was the one responsible for that incident. The aftermath of this helped shape Feodor's cynical nature and led to his radical desire to change the world; even if that means tearing it out of the sky.
  • Dead Person Conversation: He has a number of rather unpleasant conversations with Willem after he finds their corpse.
  • Deuteragonist: Is the main male character of Suka Moka.
  • Did You Just Have Tea With Cthulhu: Not many people would attempt to strike a deal with one of the 17 Beasts. Fortunately the Beast in question was Willem, who wasn’t aiming for any kind Faustian Bargain.
  • Ensign Newbie: He’s fresh from the academy and hasn’t served in the military for very long. This only puts him in further contrast with Willem, who is much more experienced due to his time as a Child Soldier.
  • Guile Hero: Imps aren’t exactly known for their physical strength, which often forces him to rely on trickery to even the odds in a fight.
  • Gut Feeling: He can tell almost instantly that Tiat has some serious emotional issues when he first sees her.
  • Has a Type: He admits to having a preference for Cat Girls.
  • Insecure Love Interest: He believes that a person as sinful as himself doesn't deserve a girl's love.
  • Interspecies Romance: He was at one point engaged to a Cat Girl "Marguerite Medicis." He also seems fine with fairies in spite of his initial discomfort around Tiat
  • I Didn't Mean to Turn You On: He did not anticipate that Elba would develop a sexual attraction to him after he used his cursed eyes to brainwash her.
  • Jerk with a Heart of Gold: His instinctive reaction to seeing someone struggling with personal problems is to walk the other way. Yet for some reason he still stops to talk to Tiat after he sees her on the ledge.
  • Love Triangle: Both Tiat and Elba develop romantic feelings for him. The addition of his former fiancée Marguerite makes things even more complicated.
  • More Than Mind Control: Imps have an ability that makes targeted individuals very open to suggestion. Due to centuries of intermixing with other races, however, it’s lost most of its effectiveness. Feodor can only barely use this ability under limited circumstances and he mostly uses other means to manipulate people instead.
  • Mr. Exposition: He has a tendency to go on long-winded monologues about various subjects. For example, his attempt to warn Tiat about the steam vent she was sitting next to leads to a lecture about the town’s history. By the time he gets around to telling her about the vent, she’d already been blasted into a nearby water tank.
  • Mystical White Hair: If it weren’t for his unusual hair and eye color you’d easily mistake him for a human at first glance.
  • Not So Different: Oddly enough he’s rather similar to Willem in his desire to protect the Leprechauns. Both of them want to make Règles Aile aware of how much they owe the fairies by creating a major crisis. The only difference is that Feodor’s plan is on a much larger scale than Willem's.
  • Our Demons Are Different: Like trolls, imps evolved a very humanlike appearance to hide among the Emnetwiht in the distant past.
  • Parental Substitute: Ryehl clearly sees him as one. She even calls him “father” while tearfully begging him not to leave Island 38.
  • Perfectly Arranged Marriage: He was supposed to end up in one of these. His family tried to set him up with a fiancé when he was only ten. Though initially sceptical, he found himself infatuated with his even younger fiancé and began to look forward to their set-piece romantic encounters. Seven years later it’s apparent that something went wrong because he is still very much single.
  • Princely Young Man: He has the looks and arrogance you’d expect out of a young aristocrat.
  • Psychic Link: His cursed eyes work by forming one of these with the target. This link puts an enourmous strain on him and can potentially kill him if he doesn’t cut it by killing the other person. Naturally, this puts Feodor in a major dilemma when he starts falling in love with one of the people he’s linked to.
  • Rage Against the Reflection: He punches a mirror in volume 4 after Willem mocks him from the other side.
  • Reassigned to Antarctica: He’s part of the Guardian Wings Military’s 5th Division, which is regarded as a dumping ground for troublesome soldiers.
  • Replacement Goldfish: It’s pretty clear that some of the Leprechauns see him as a potential replacement for Willem. Tiat even asks him if he’d consider moving to the Warehouse once everything is over.
  • Stepford Smiler: Very few of his smiles are genuine.
  • Then Let Me Be Evil: Imps have been demonized for as long as they can remember, first by humans and then by just about every other race. It’s no surprise then that Feodor believes that his entire race is tainted by evil, which is why he is more than willing to carry out evil actions for the greater good.
  • Used to Be a Sweet Kid: It’s very obvious that he Took a Level in Cynic following his first appearance in Suka Moka’s prologue.
  • Weak, but Skilled: He makes up for his race’s lack of physical strength with a number of techniques designed to level the playing field.
  • Well-Intentioned Extremist: His actions arguably push him into Villain Protagonist territory. In any other series he likely would be considered the villain. However, the situation in Règles Aile is so desperate that his plan might be their best chance of survival.
  • We Have Become Complacent: He believes that Règles Aile has become blind to the true dangers of the 17 Beasts. Pushing all of the burdens of battle onto the leprechauns has also robbed the people of their ability to fight back against the Beasts. His primary goal is to make Règles Aile aware of its vulnerability before it’s too late.

Nax Selzel

Feodor’s friend and fellow soldier from the 5th Divison.

  • Bishounen: If Lyell wasn’t such a ghost town he’d probably have no trouble picking up girls with his looks.
  • The Casanova: Girls are his main interest.
  • Double Reverse Quadruple Agent: His true loyalties are a mystery, especially given his tendency to work for the highest bidder. Odette seems to be his current employer and it’s hinted that his work for her has to do with more than just money.
  • Knowledge Broker: He often deals with sensitive knowledge.
  • The Mole: He assists Feodor with his information gathering campaign.
  • Romantic Wingman: He is more than happy to encourage Feodor’s romantic endeavors.
  • Subordinate Excuse: He jokes that Feodor’s new female subordinates will soon be fawning over him due to this trope.
  • Well-Intentioned Extremist: He’s one of the few people aware of Feodor’s true plans. He shares Feodor’s belief that Règles Aile is doomed unless drastic action is taken.
  • Winged Humanoid: His race’s most distinguishing feature is a pair of large wings on their backs.

Elba Affa Muresmaurea

A fairy who died in a civil war 30 years before Suka Moka.

  • Anti-Hero: She’s the only fairy ever known to have rebelled against the military.
  • Aren't You Going to Ravish Me?: She casually suggests that Feodor could have his way with her if he wanted. Feodor is rather shocked by this brazen proposal.
  • Brainwashed: Downplayed example. Feodor is forced to use his cursed eyes on her after she tries to kill him. However, their goals for the most part align and she doesn’t seem to mind being under his control.
  • Berserk Button
    • In her past life she developed an intense hatred for her fellow Leprechauns to the point where she attacks Collon and Pannibal on sight.
    • She will kick your ass if you lay a finger on Feodor.
  • Betty and Veronica: She’s the Veronica to Tiat’s Betty and Feodor’s Archie.
  • Curb-Stomp Battle: Her wartime experience allows her to easily thrash Tiat and even Nopht in a fight.
  • Dark and Troubled Past: During the civil war she was ordered to target an airship only to find out afterwards that it was full of civilian refugees. Her anger at being used like this led to her defection and eventual fight to the death against Nasania.
  • Defector from Decadence: She defected from the Guardian Wings Military during the civil war out of anger from how they callously used fairies as weapons. This later leads to her assisting Jessman following her reincarnation.
  • Devoted to You: Feodor is forced to use his cursed eyes on her after she mistakes him for an enemy and tries to strangle him. It works a bit too well because she falls madly in love with him as a result.
  • Foil: To Ithea. Both are fairies that took over someone else’s body after encroachment. Unlike Ithea, however, Elba does not even attempt to resume the life of her former self. The “new” Ithea dedicated her entire existence to living out the life of the “old” Ithea. In contrast, Elba could not be more different personality wise from Lakhesh and immediately ditches any semblance of Lakhesh’s identity when she takes over. Their relationship with the main female character in their respective stories also differs drastically. Ithea is a supportive friend and Shipper on Deck for Chtholly. Elba, on the other hand, sees Tiat as an enemy and is clearly her main love rival. Furthermore, it is heavily implied in the sequel that Ithea is actually the reincarnation of Elba’s friend turned enemy Nasania, making their status as foils to one another even more apparent.
  • Identity Amnesia: She initially has very little memory of either of her previous lives.
  • Reincarnation: Lakhesh is her present day reincarnation, who she eventually replaces following the former’s enroachment.
  • Sexy Backless Outfit: She wears one of these while hiding out at the safe house. It only serves to further contrast her with Lakhesh, who was easily the most conservatively dressed Leprechaun.
  • She Cleans Up Nicely: She looks very alluring when she actually dresses up.
  • Shell-Shocked Veteran: Her experiences in the war left a major impact on her. When she first wakes up she immediately tries to attack Collon and Pannibal after mistaking them for enemies. She later tries to strangle Feodor when he runs into her, forcing him to use his eyes to bring her under control.
  • Split Personality: Her present day personality is a mix of Elba and whatever is left of Lakhesh.
  • Violently Protective Girlfriend: Elba is VERY protective of Feodor, which is why she beats the shit out of Nopht after the other fairy attacked him.
  • Walking Spoiler: Her replacement of Lakhesh is one of the biggest twists in the sequel.
  • We Used to Be Friends: She was once close friends with Nasania until differences in belief put them on opposite sides of the civil war.

    Emnetwiht Braves 

Lillia Asplay
Voiced by: Rina Sato (Japanese)

A Regal Brave, former wielder of Seniorious, who worked with Willem in the past.

  • The Ace: She's a Regal Brave. That's all that needs to be said.
  • Betty and Veronica: In the past, she was the Veronica to Almaria’s Betty and Willem’s Archie.
  • Born Lucky: Subverted. She seems like this at first. However, Seniorious only picks those with an extremely tragic background. Underneath her prideful exterior, she’s an emotional wreck.
  • Cosmic Plaything: The self-described unhappiest girl in the world was no stranger to despair.
  • Cruel to Be Kind: The light novels reveal that the main reason Willem isn't a Regal Brave like she is despite all his talents is because she actively prevented him from becoming one, knowing how tragic the life of a Regal Brave is firsthand and wanting Willem to be happy because so many people loved him.
  • Dark and Troubled Past: Heavily implied with some of her dialogue in the light novel as well as with how Seniorious chooses its wielders. Her EX side story reveals some of that past.
  • A Day in the Limelight: She gets her own side story in EX, which focuses on her time as a brave.
  • Dramatic Irony: She performs a Heroic Sacrifice so that Willem could return home to his family, unaware of the fact that he’d already been frozen and would never see his family again.
  • Everyone Can See It: Her feelings for Willem were pretty apparent to most of her comrades.
  • Failure Hero: She sacrificed everything to protect humanity. It was sadly not enough to change humanity’s fate in the end. What makes it worse is that the events that led to humanity’s extinction were completely outside of her control.
  • Foil: To Chtholly. Both girls were wielders of Seniorious who ultimately developed romantic feelings for Willem. However, Lillia chose to bury those feelings under a layer of scorn out of fear that they would prevent her from doing her duty, making herself miserable in the process. Chtholly on the other hand openly admits her feelings for Willem and tries to pursue a future with him. Both sacrifice themselves to protect Willem, but only Chtholly’s sacrifice has any meaning. Unlike, Lillia, she dies knowing that she was loved by the person she loved most and in doing so saved the lives of countless others. In contrast, Lillia never gets the chance to be happy with Willem due to her own choices and ultimately fails to save anyone.
  • Heroic Sacrifice: Decided to be the one who would kill Elq in an effort to protect Willem.
  • The Lost Lenore: Willem regards her as yet another one of the people he failed to protect in the past.
  • Not So Above It All: She, Willem and Souwong at one point fight over cookies Almaria made like they were little kids (which, back then, might apply to Souwong only).
  • The Power of Love: Finishes off Elq so that Willem won't have to.
  • Red-Headed Heroine: She's hot-blooded, a very skilled Regal Brave, and loves teasing Willem.
  • Senseless Sacrifice: Her ultimately killing Elq did nothing to stop Willem from fighting in the war, and it inevitably ended with him being frozen in stone following his battle with Ebon Candle, never to be seen again until more than 500 years later. The revelation about the emnetwihts' true nature only further cemented the pointlessness of her actions, proving that she is the tragic heroine worthy of wielding Seniorious, the blade that chooses only those who can never meet happiness in their lives.
  • She Cleans Up Nicely: Wore a red dress in EX volume and looked completely regal while wearing it.
  • Ship Tease: Has a considerable amount with Willem. She openly admitted to having romantic feelings for him and it’s strongly hinted that Willem secretly felt the same.
  • Spell My Name with an "S": The official site spells her name as Lillia, but the anime shows it on-screen as Lilya.
  • Stepford Smiler: She puts on an air of arrogance around Willem and their comrades and can be quite mischievous, but take in the fact that the prerequisite to wielding Seniorious in combat and to qualify as a Regal Brave is to be someone whose life was tragic up until the present and she's definitely this.
  • There Are No Coincidences: Lillia always knew that Nils was so elusive that he can never be found no matter how hard she or Willem tried. Then, following a lead on her mission to hunt for the leader of True World, Lillia inexplicably runs into Nils seemingly by accident. She immediately puts two and two together and nonchalantly asks him about it. Nils actually didn't say anything, but the expression on his face confirmed Lillia's suspicions.
  • Tsundere: Acts this way towards Willem. She intentionally treats Willem badly despite her romantic feeling towards him, because acting on those feelings would interfere with her ability to be a Regal Brave.
  • What Happened to the Mouse?: She survived her encounter with Elq, but the mental damage left her essentially braindead. She was last known to be recovering in the Imperial Capitol. Since this place was one of the first to be overrun by the 17 Beasts she in all likelihood was either killed or turned into a Beast.
  • Why Can't I Hate You?: As much as she tried, she could never bring herself to hate Willem and even ended up falling for him.
  • Would Hurt a Child: Lillia killed Elq, who appears as a child, to complete her mission of defeating the Visitors.


One of the braves who worked with Willem in the past.
  • The Casanova: His romantic exploits rival his achievements as a brave.
  • Chekhov's Gun:
    • Willem's trip to the surface in Volume 3 involves finding the Dug Weapon Lapidemsibilus, belonging to his old comrade Navrutri, mentioned a couple of times previously in Willem's flashbacks.
    • Willem briefly questions how Navrutri's Kalliyon could have winded up in Gomag, since he's not even a local. Volume 4 reveals that Navrutri had his last stand against the awakening Beasts in True World's headquarters underneath Willem's orphanage.
  • Cruel and Unusual Death: He slowly bleeds to death from the many injuries he sustained fighting the Aurora. Due to his sword’s ability he remains fully conscious through all of it. His last expression is of complete agony due to the pain of his wounds and the knowledge that his mission had failed.
  • Early-Bird Cameo: Appears in one of Elq's flashbacks picking up an unconscious Lillia in the penultimate episode of the anime, one volume before he is officially introduced in the light novels.
  • Hidden Depths: Who would have expected a man with so many vices to have such strong religious beliefs.
  • Intergenerational Friendship: He's described as being in his thirties, but he seems to have camaraderie with both Willem and the other Braves on one end, as well as Nils and (if one of Willem's dreams are to be believed) the Emperor on the other.
  • Impaled with Extreme Prejudice: He is impaled multiple times by the Aurora. By the time Willem finds him he's a bloody mess with only his sword's special ability keeping him conscious.
  • The Mole: Is actually a spy for the moderate faction of True World.
  • Off Screen Moment Of Awesome: Willem finds him next to a mountain of dead Aurora corpses. Unfortunately, he didn’t emerge unscathed and ends up dying due to his many injuries shortly afterwards.
  • Right for the Wrong Reasons: He quickly sees through Willem’s cover story about how he ended up in Gomag after being declared dead and that there is more to the story than Willem simply waking up in the orphanage following the battle. What he doesn’t realize is that Willem was frozen for 500 years and only recently had stumbled into a barrier world created by the first beast. Navrutri and the other residents of the world think they’re living in the present. In reality, their souls have been stuck in a Lotus-Eater Machine for 500 years, with no one realizing any time has passed.

Souwong Kandel
Click here to see his younger self 
Voiced by: Mugihito (Present) and Mutsumi Tamura (Younger) (Japanese), Charles Campbell (English)

A skilled magician who fought alongside Willem 500 years ago, Souwong fought and lost against a visitor, but cast a spell on himself before dying, preventing his death. When the beasts emerged, he led the survivors onto the flying islands.

  • The Archmage: The only known mage in the setting and is quite the influential person among the people in the present day.
  • Back from the Dead: He was killed by Jade Nail during the war with the Visitors, but managed to place a delayed revival spell on himself just before his death. He eventually came back to life as a barrowwhit.
  • Barrier Maiden: He and Ebon Candle use their combined power to keep Règles Aile afloat and away from the threat of most of the Beasts.
  • Been There, Shaped History: He was originally one of Willem’s comrades in the war against the Visitors. Later, after the 17 Beasts emerged, he helped create the floating islands and played a major role in rebuilding civilization. Since then, he’s been the unofficial leader of Règles Aile for all of its 500-year history.
  • Big Brother Worship: Looked up to Willem when he was younger and even admits in the present day that he always saw him as a surrogate older brother figure.
  • Big Good: Most of Règles Aile views him as a legendary figure responsible for saving civilization.
  • Bishounen: When he was younger. It was even stated in-story that his face would probably earn him the attraction of many young girls if they weren't locked in a war with the Visitors.
  • Body Horror: Has a large gaping magical hole in his body where his heart used to be, which allows him to become effectively immortal.
  • Chekhov's Gun: Souwong told Willem he used a type of magic to try to find Willem 500 years ago by detecting his heartbeat, and Souwong only gave up because his search turned up empty (Willem had to point out that he was petrified the whole time, so he doesn't have a heart to speak of then). At the end of Volume 3 (as well as the end of the anime), Souwong uses that magic again, and he discovers that Willem (and Nephren) are still alive.
  • Child Prodigy: He was only twelve when he fought alongside Willem and the rest of the Braves during the war with the Visitors as their magician, and yet, he could already cast very powerful and advanced spells at that age, most especially the curse he used to cheat death with.
  • Costume Porn: A dandy who loves his white mantles. He was teased for it by his friends.
  • Deus Exit Machina: His absence in Chanteuse's barrier world is lampshaded in that Willem needed Souwong's vast knowledge in order to make sense of the situation. Too bad that at the time frame of the barrier world, Souwong is Only Mostly Dead (or comatose, that other characters thought).
  • Embarrassing Nickname: He seemingly doesn't like his Red Baron, although this might be because of how Willem makes fun of him for it.
  • Enemy Mine: The threat of the 17 Beasts was enough for him to work together with Ebon Candle, one of mankind’s mortal enemies, in order to save the surviving races.
  • King Incognito: Spends a portion of Volume 5 in Corna di Luce, occasionally walking into town and even runs into Rhan in the process; the latter doesn't recognize him at first, even though there's a statue dedicated to Souwong somewhere in the same city.
  • I Was Quite the Looker: In his character art, and the one flashback we've seen of him when Willem was still a Quasi-Brave, Souwong was a pretty-looking blonde young man back in his youth. So pretty that Almaria apparently mistook him for a girl.
  • Not So Above It All: Reverts to acting like a bratty kid throughout most of his reunion with Willem.
  • Not So Different: His plan to retake the surface is driven by a nostalgic desire to reclaim a lost past. This is, ironically, the same thing that motivated the 17 Beasts to destroy all life on the surface in the first place.
  • Not Quite Human: Because of the curse he used to extend his life, he remarks that he does not qualify as human any more. It's even reflected in his character bio in the official website where he's listed as a "barrowwhit" for his race as opposed to his younger self who's still classified as an emnetwiht.
  • Odd Friendship: He only has two real friends in the present. One of them is Ebon Candle, a talking skull/former nemesis. The other is Willem who, while still technically older, now looks MUCH younger than his former comrade due to his petrification.
  • Really 700 Years Old: He's younger than Willem, but like him, he's over 500 years old.
  • Red Baron: Like Willem, he was known among the Braves as the Magus of the Polar Star.
  • Running Gag: His assistants are always intimidated when he speaks to them, even though he doesn't mean to.
  • Saying Too Much: Suwong's indifference to the Fairies is one of the things that clued Willem in on the fact that he and Ebo are the ones who created them. Ebo had already figured it out before Suwong would that Willem has now built an attachment to the Fairies, and also knew that Willem is going to get angry at them.
  • The Slow Path: Willem spent 500 years petrified, while Souwong spent those same 500 years rebuilding civilization with the survivors of the Beasts. By the time the two friends meet again, Willem is still (appearance-wise) a young man while Souwong is now an old codger.
  • Tsundere: The first time he reunites with Willem after a long 500 years of thinking the latter died, he accidentally spits out that he cried buckets of tears for him following Willem's climactic battle with Ebon Candle...then quickly denies it and pretends that he didn't miss him the least during his disappearance after all those years.
    Souwong: Give me back the tears I shed that day!
    Willem: Hm? You cried for me?
  • We Have Reserves: A sympathetic version than most, where he sees the Fairies as expendable weapons that must be sacrificed for the sake of everyone else living in Règles Aile. Willem nearly punches his lights out for this. He later admits that he’s not particularly proud of this strategy.
  • The Worf Effect: It really shows just how powerful Elq’s Guardians were when one of them killed humanity’s most talented mage with barely any effort. This makes Willem’s victory over Ebon Candle even more impressive and is probably why Souwong admits that even with 500 years of experience he’s probably still no match for his former comrade.

Literal visitors to the world, who could not find their way back to their homes. As they were immortal and could not die unless in their homeland, most of them broke their souls to live on the land without harming other inhabitants.

Elq Hrqstn

Voiced by: Hikari Okada (Japanese), Monica Rial (English)

The last of the visitors, a young redheaded child who remained in a barrier and was protected by three guardians.

  • Adorable Abomination: She looks like a normal child, but there’s a very good reason why she was kept in total isolation for most of her life. Lillia’s mind was completely destroyed simply by being in Elq’s presence for a few minutes.
  • Catchphrase: Often says that girls who fall in love with Willem have “bad taste”. Examples include Lillia, Chtholly, Nephren, and maybe herself.
  • Children Are Innocent: Does not understand the concepts of death, pain, or suffering, and is more inquisitive about Lilla's suffering.
  • Clingy Jealous Girl: She claims that Willem is too “promiscuous” around older women.
  • Cloudcuckoolander: Due to her poor social skills she often gives off this impression. When Willem first meets her he assumes that she’s just some weird girl who is trying to hit on him in the middle of a freaking apocalypse.
  • Creepy Monotone: The anime adds this aspect to her whenever Chtholly is experiencing her Encroachment.
  • Eldritch Abomination: She’s a lot more adorable than most examples. Unfortunately, this doesn’t stop her from inflicting Mind Rape on ordinary humans through her mere presence. There’s also the fact that she exists in a deathlike slumber beneath a ruined city much like a certain Great Old One. Combined with Chtholly’s Meaningful Name this effectively makes her Suka Suka’s version of Cthulhu.
  • I Choose to Stay: She opts to stick around the dying world for a bit longer rather than leave on the Visitor’s starship at the end of the light novel.
  • Immortal Immaturity: Acts like a child despite being one of the oldest characters in the series.
  • Mind Rape: Just by asking an innocent question, she has this effect on Lillia.
  • Moment Killer: Chtholly's Imagine Spot of a married life with Willem was cut off by a vision of Elq rolling on the floor laughing at her, causing Chtholly to snap at Elq subconsciously.
  • Only Mostly Dead: While her body is dead because she was stabbed by Seniorious, which automatically marks anyone wounded by it as "dead", her nature as a Visitor allows her consciousness to still endure and communicate with others. Thus, she retains some degree of influence over the world via the leprechauns.
  • Older Than They Look: The child-like version of her that Chtholly first meets is actually just an astral projection created when Elq dreams. Her main soul fragment continued to age even after her “death”, so she now has the appearance of a 15-year-old girl. It gets confusing when she reunites with her old body which hadn’t aged a day in 500 years.
  • Pieces of God: The leprechauns are all this to her, as following her death, a curse was used with the intent of finely grinding her soul into powder fragments to maintain the curse on humanity. It failed and instead shattered half of her soul into pebble-sized pieces, with each piece reincarnating into a leprechaun. The other half remains in Elq's corpse and contains her consciousness.
  • Please Don't Leave Me: Elq put Chtholly into a coma for a second time to save her mind before her Encroachment completely takes over. When Chtholly requests to wake up once more (to save Willem and Ren from the Timmere), Elq reluctantly complies, and would rather have Chtholly stay with her, since she knows she will never see Chtholly again.
  • Precocious Crush: Her guardians seem to think she has one of these on Willem. Of course she’s older than humanity itself, so the precocious part might be a bit of a stretch.
  • Psychic Link: She possesses one with every leprechaun, allowing her to see and experience things through their eyes. She uses this to communicate directly with Chtholly during the latter's encroachment.
  • Rapunzel Hair: Her hair is longer than she is tall.
  • Seeing Through Another's Eyes: She can see and experience everything from all leprechauns past and present, and can review every moment of their lives at her leisure. This is because each leprechaun is a living incarnation of a piece of her soul.
  • Taken for Granite: Lillia stabs her with a hex using Seniorious's power that petrifies the victim into being encased into a block of ice. The curse is so powerful that despite more than 500 years passing after her "death", she's still perfectly frozen and intact after all those years.
  • Unwitting Instigator of Doom: After meeting Lillia she wanted to be just like the brave. This included Lillia’s Tragic Hero background and predisposition towards Heroic Sacrifice. Unfortunately, this desire also influenced the behavior of the Leprechauns formed from her soul. This resulted in countless generations of fairies sacrificing themselves in battle, because that’s what Lillia would have done. Chtholly was the only one to manage to break from this cycle, though she still ultimately died.
  • Vague Age: In Chtholly's visions she appears to be under 10. However, her actual soul fragment appears to be 15 in Shiantor's barrier world. To make things even more confusing, that fragment later gets reunited with her old body, which is still childlike.
  • Walking Spoiler: Knowing a substantial amount about her spoils the backstory of the plot as well as the nature of the leprechauns.
  • What Does She See in Him?: While she appreciates his Nice Guy attitude, Elq doesn't quite get how Chtholly and Lillia would fall for a guy like Willem, since Elq isn't as impressed with him as they were.
  • Wound That Will Not Heal: Lillia's stab wound is still present on her corpse's chest, though it's noticeably absent whenever she converses with Chtholly in her visions.
  • You Remind Me of X: When Willem first meets her in the barrier world he can’t help but get the feeling he’s met her before. Her red hair reminded him specifically of Chtholly which isn’t surprising because Chtholly’s encroachment also meant that she was physically turning into Elq. And technically he has met her because every Leprechaun is a fragment of her soul.

Ebon Candle (Ebo)

Voiced by: Takashi Matsuyama (Japanese), Jeremy Inman (English)

One of the guardians who protect Elq, Ebo was defeated by Willem many years ago. As a result of his injuries, his reincarnation is incomplete, and he now takes the form of a talking skull.

  • Battle Aura: In their reunion, Ebo exhibits a dark, ominous glow as he prepares to take revenge on Willem...but when the latter turns down the challenge, Ebo sags and shuts down his aura in disappointment.
  • Barrier Maiden: He and Souwong use their combined power to keep Règles Aile afloat and away from the threat of most of the Beasts. Ebo brags that he contributes 4/5s of the magical power.
  • But for Me, It Was Tuesday: A variant. Willem does recognize Ebon Candle after 5 centuries (and the latter having been reduced to a talking skull). What really annoyed Ebo, however, was that Willem never realized that he was the reason Ebo is in that state in the first place.
  • Came Back Wrong: Due to being injured by Willem and going into hibernation, he takes the form of a talking skull, as opposed to the colossal rock-like behemoth he was centuries ago.
  • Expecting Someone Taller: Since Willem remembered fighting him as a gigantic monstrosity before he was petrified, Ebon's current appearance as a talking skull missing the rest of his body caught Willem by surprise.
  • Expy: His original armored form had a very Forerunner-like design. He even wielded a weapon similar to Halo’s iconic energy sword. For a servant of the extraterrestrial Visitors, the Sci-fi look isn’t all too surprising.
  • Freeze-Frame Bonus: The anime very briefly shows a skull emerging from Ebo's burning remains, slightly hinting at what he's reduced to when he shows up later in the series.
  • I Was Quite the Looker: He was a badass armored Goliath before Willem burned his body to a crisp.
  • Misplaced Vegetation: Most likely because of his power, his home in the 2nd island is filled with plant life from all over the four seasons.
  • Ocular Gushers: Once he's finally reunited with Elq and Carmine Lake near the end of the novels, Ebo couldn't control his own emotions.
  • Odd Friendship: They have to tolerate each other for 500 years working together to protect Règles Aile, but by the time Willem meets them again, Suwong and Ebon Candle have veered into Vitriolic Best Buds territory.
  • Traitor Shot: In the anime, while Souwong was telling Willem about his theories on the Beasts' origins, the scene focuses on Ebo a couple of times giving Souwong a dubious look while keeping silent the whole time. As a servant to the Visitors, Ebo would most likely know the truth about the Beasts, and that look he's giving Souwong is because the latter is withholding such information from Willem on purpose, something that Ebo calls him out on after Willem leaves.
  • Worf Had the Flu: Once reunited, Carma gets on Ebo's case because it was his job to restore the Visitors' starship. Ebo had been busy protecting Règles Aile with Souwong that he didn't have the time (or power) to do so.
  • Worthy Opponent: Sees Willem as one. Willem doesn't quite reciprocate the gesture though.

Jade Nail

The second of the three guardians who protected Elq.
  • Always a Bigger Fish: He was the only Guardian to remain undefeated by the Braves. Which makes it all the more shocking to find out that something did him in.
  • The Cameo: He never showed up in the novel or the anime, yet the latter features a crude (perhaps inaccurate) picture of all three Poteau/Guardians in the ruins of Gomag. Jade Nail's illustration looked downright demonic.
  • Curb-Stomp Battle: He easily defeated Souwong and Emissa when they tried to challenge him.
  • Dead All Along: Someone, or something, killed him at some point in the past. Later in Suka Moka Volume 6, it is revealed that he was killed by Helva T. Lontis, the girl who would eventually become Vincra the Fourteenth Beast.
  • Hero Killer: He killed Souwong and Emissa, though the former managed to revive himself later.
  • The Man Behind the Man: Nils speculates that he, rather than Elq, was the one to order humanity’s extermination. This is most likely true, given that Elq was apparently kept in the dark about the actions her guardians took in her name. Confirmed in Suka Moka Volume 6 where its revealed that he was the one who proposed it to the other two Poteau.
  • No Good Deed Goes Unpunished: At the end of the Visitor-Human War he was faced by a human army seeking to end the war once and for all. Realizing that the entire conflict was pointless now that Elq was dead, he made an offer to the human forces. Humanity was already on the verge of devolving into the 17 Beasts, so Jade Nail offered turn his would be enemies into Imps to avoid that fate. Unfortunately, this only led to bitter infighting in the human camp that resulted in the deaths of all but one of the members of the army. The sole survivor, by this point already beginning to transform into the 14th Beast, spent their last moments of humanity cursing Jade Nail out of spite for the deaths of their comrades.
  • Schmuck Bait: He died with the expectation that Ebon Candle would inevitably attempt to revive him. Someone else apparently realized this as well. That’s why they placed a second curse on his corpse and used it to seal an unknown Beast inside. The inevitable revival attempt released this dormant Beast; after which all contact was lost with Island 2.
  • Well-Intentioned Extremist: In order to protect Elq and prevent the world’s destruction he was prepared to exterminate the entire human race.
  • What Happened to the Mouse?: It's never revealed what happened to him following that battle. It turns out he was killed by the 14th Beast.

Carmine Lake (Carma)

The last of the guardians who protected Elq. Shaped like a fish, she later attached herself to Nephren.
  • Early-Bird Cameo: Her old form shows up in a potentially exaggerated human propaganda poster in the anime before her actual introduction to the story.
  • The Gadfly: Never shuts up. Made worse by the fact that the only person who can usually see her is her host.
  • I Was Quite the Looker: She claims that her present day form is a far cry from how she originally looked. Judging by her appearance in the human propaganda poster, she was once a massive eastern style dragon.
  • Irony: The most talkative character in the series ends up stuck together with Nephren of all people.
  • No Indoor Voice: A consequence of her only being able to be heard by her host. Unfortunately Willem can hear her due to both him and Nephren possessing part of Shiantor. This results in him getting blown back by a suddenly shouting flying fish ranting about his various faults.
  • Parental Substitute: To Elq. Notably, she has the most motherly attitude towards her compared to her fellow Poteau.
  • Shipper on Deck: She initially thinks Elq’s interest in Willem is romantic in nature and seems more than willing to encourage such a pairing. Later, she also seems to be one for Nephren and Willem, even going on an epic rant against the now amnesiac Willem for forgetting the girl. Of course Nephren technically is Elq, so she probably has no problem shipping both of them with Willem.

    Other Characters 

Grick Graycrack

Voiced by: Shigeru Chiba (Japanese), Bryan Massey (English)
A Goblin friend of Willem who gets him the job of Weapons caretaker.

  • Adventurer Archaeologist: Grick works as a salvager, who goes down to the surface to hunt for relics, weapons and other items, at the risk of being killed by the beasts.
  • Alliterative Name: Grick Graycrack.
  • Declaration of Protection: To Nephren during the events of Volume 5, making it his personal mission to safely escort her back to the Warehouse. He probably believes that it was what Willem would have wanted.
  • Face of a Thug: He's a Goblin; Willem knew him for such a long time (practically since Willem's "resurrection") yet he still couldn't comprehend that Grick is actually a Nice Guy.
  • Fire-Forged Friends: During the mission to the surface (one of the critical moments of Volume 3) Grick has repeatedly butted heads with the Gremlin First Officer. After barely escaping a mass Timmere attack with their lives, however, the two of them seem to have started tolerating one another. By Volume 5, they're still working together, and the First Officer doesn't take Grick's advice for granted anymore.
  • Mistaken for Pedophile: Willem jokes that as long as he's around, Grick will never get his hands on any of the girls.
  • Noodle Incident: He's actually a former member of the Guardian Wings Military (if only for less than a year), per Buronny's background check on Grick. Whatever happened that made him leave the military (especially since Grick chose the life of a salvager which in these times is just as dangerous as a soldier's), he's not telling.
  • Oh, Crap!: His reaction when he realizes Elpis has recalled all of its merchants from island 11. Not long after that, they release a swarm of captured Aurora onto the island to aid in their coup effort.
  • Our Goblins Are Different: He's a level-headed individual who shows a great deal of concern for others. These traits are rarely associated with goblins in other works.
  • Secret Keeper: He and his expedition team found a petrified Willem, quite possibly the biggest archaeological find in Règles Aile's history. But, when Willem found out he's the Last of His Kind, he requests that he be kept under wraps.
  • Shipper on Deck: Subtle, but its implied one other reason he got Willem the job of Warehouse caretaker is to arrange a reunion between Willem and Nyglattho. That's what Willem thinks anyway since Grick never mentioned that Nyglattho was the one looking for a new co-worker.
  • Shoot the Shaggy Dog: He saves a soldier’s life during the attack on the ground expedition’s camp. That same soldier’s corpse can later be seen during the Timere attack on the Plantagenista. Bonus points for the soldier being a literal shaggy dog.
  • Younger Than They Look: Despite acting like he's older, he's actually only 15, younger than Willem and making him the same age as Chtholly.

Officer Limeskin
Voiced by: Jurota Kosugi (Japanese), Christopher Sabat (English)

The Lizardfolk in charge of the Leprechauns. Well-respected by other soldiers.

  • Batman Gambit: When Willem refuses Limeskin's request to help Phyra, Limeskin instead opts to pass the request to Chtholly. Limeskin knew that Willem would never leave any of the girls with such a burden, so he winds up having to take responsibility for their sake anyway.
  • The Chains of Commanding: When the Timmere threat appears to have ceased indefinitely, if it were up to him, the Leprechauns would have been allowed to retire and live normal lives from here on. Unfortunately, his own higher-ups rejected his suggestion.
  • Cultured Warrior: He has an almost poetic way of speaking that can sometimes be difficult for others to understand.
  • A Father to His Men:
    • Implied, as he values the Leprechauns' lives over uncertain victory by honouring Chtholly's wish to live instead of taking herself and the Timere out in the battle to reclaim one of the islands that was taken over.
    • When the Saxifraga expedition is compromised, one of the first things he wants to know are the whereabouts and well-being of the two Fairies aboard, Rhan and Nopht.
  • Honorary Uncle: Of Phyracorlybia.
  • Large and in Charge: He's big and his size emphasizes how he's in command of his fleet.
  • Not So Above It All: Willem's reputation as being "into little girls" was a result of Limeskin's report.
  • An Officer and a Gentleman: He's actually quite philosophical and poetic in spite of his huge stature and position in the military.
  • Reality Ensues: He's the commanding officer in charge of the defense of the 15th Island, and it was his decision to sink the island. Because of such a responsibility, he was placed under house arrest for a brief time.
  • Reasonable Authority Figure: Accepts the new way of fighting beasts suggested by Willem, and would rather sink the island being attacked than taking the risk of a suicide explosion.
  • Reptiles Are Abhorrent: Subverted. He's one of the nicest characters in the story.
  • Screw the Rules, I Make Them!: After the battle of the 15th island Limeskin permits the Fairies to use communication crystals so they can contact their family back at the Warehouse.
  • Vague Age: To the point that Willem himself couldn't tell how old Limeskin really is. It came as a surprise for Willem that Limeskin had a daughter.

Buronny Maxi

The rabbitfolk who arranges for Willem Kmetsch to meet with the Great Sage, Souwong Kandel. He is also a member of the Guardian Wings Military Police.

  • Benevolent Conspiracy: As shady as he might seem, he’s still staunchly dedicated to protecting Règles Aile. This is why he secretly works with a number of prominent members of the government and military in order to stop the growing conspiracy against the Warehouse.
  • Contrived Coincidence: He issued a summons to Willem to learn more about the latter's skills and immediately thought that it is something to be consulted with the Great Sage. Apparently, Buronny might not even be aware he's actually arranging a meeting between two old friends.
  • Mistaken for Pedophile: His intel tells him Willem has a thing for young girls. Suffice to say his sources were a bit inaccurate.
  • Mr. Exposition: Gives some pretty big info dumps on the political situation of Règles Aile.
  • Secret Police: He’s a member of the military police who frequently engages in secretive work.

Phyracorlybia Dorio
Voiced by: Honoka Inoue (Japanese), Tia Ballard (English)

A Lycanthrope and an inhabitant of island 58.

  • The Bait: She is unwittingly used in this manner by Willem, as he directs her to take him to a secluded and confined location in order to draw out the Annihilation Knights.
  • Berserk Button: She did not appreciate Willem using her as The Bait and also touching her abdomen when they first met, as her race considers it an intimate part of the body.
  • Brainless Beauty: She never questioned why Willem would ask her to lead them to a secluded part of town after she told him that her family was being targeted by terrorists.
  • Chekhov's Gunman: Her father becomes an important figure in the allied movement against the Elpis Federation in Volume 5.
  • In-Series Nickname: Phyra.
  • Nice Hat: Is always seen wearing a bonnet on her head.
  • Proper Lady: Acts the part more so than even Rhan, the most lady-like of the Leprechauns shown so far.
  • Schmuck Bait: She was the bait.
  • Tranquil Fury: At one point during her tour of Corna di Luce, Willem's party starts a conversation and decide to ignore her when Phyra wanted to take them to a good eating place. Phyra proceeds to frighten all four of them (including Ren) with merely her tone of voice.

Nils Didek Foreigner

The caretaker of the orphanage Willem and Almaria lived in who also happened to be Willem and Lillia's teacher in the Arts that turned them into the skilled Braves they were known as when the Emnetwihts were still around.
  • The Alcoholic: Nils is drunk more often than not. Willem considers it to be his least distinguished trait. Subverted when it’s revealed that Nils physically can’t get drunk due to his Visitor biology; implying that he was faking his alcohol dependency.
  • Alien Among Us: Nils is eventually revealed to be an extraterrestrial Visitor who disguised himself as a human.
  • Ambiguously Evil: As the leader of True World (and a Visitor for that matter), it was hard to figure out what his true motivations are. The fact that Willem never found out about his allegiance (whether in the past or in the present) also had something to do with this being a mystery.
  • But Now I Must Go: He can only use his Reality Warper abilities six times on a world before he has to depart for another one. He uses his final one to help Willem one last time and leaves shortly afterwards.
  • Chivalrous Pervert: If there's one other thing apart from swordsmanship that Willem took after his surrogate father, it was to treat women with kindness and respect.
  • Crouching Moron, Hidden Badass: At first glance, he appears nothing more than an alchoholic old man. However, he also happens to be a retired Regal Brave who is easily one of the most skilled fighters in the series. His public drunkenness is implied to be nothing more than a facade to hide his many behind the scenes activities.
  • Cruel to Be Kind: He makes it abundantly clear that he doesn’t think Willem is qualified to be a brave. Nothing would make him happier than for Willem to give up his heroic aspirations and try to live a normal life. The life of a brave is nothing but hardship and suffering. After all that he’s been through Willem now understands that his old master only wanted to save him from this fate.
  • Deus Exit Machina: It was stated that his disappearance prevented True World from giving Elq's corpse a thorough examination. If True World could have furthered their studies, then perhaps they might have prevented humanity from reverting back into Beasts.
  • Dirty Old Man: According to both of his pupils.
  • Master Swordsman: His swordplay is the only thing Willem will ever remark about him in a positive light.
  • Meaningful Name: His name hints at his true nature as a visitor.
  • The Mentor: To both Lillia and Willem. It was his lessons that turned them into the badasses they were later known for in life.
  • My Greatest Failure: He thinks that he should have done more to convince Willem to live a normal life rather than pursue his heroic fantasies. His decision to seal Willem’s memories is largely due to his desire to give his foster son one more chance to live a peaceful life.
  • Mysterious Past: His past is one big mystery. Almost nothing is known about his life prior to becoming a brave. Later it’s revealed that he’s a Visitor who founded True World a century before Willem’s time. His origins also differ from Elq and the other Visitors; he apparently came from a different home world and arrived separately from the original 10 Visitors.
  • Oh, Crap!: This is Nils' reaction when Lillia confronted him with his true allegiance as the leader of True World. In fact, his very expression was what convinced Lillia in the first place.
  • Parental Substitute: He should be one to Willem and the rest of the orphans in his orphanage but he's rarely ever home and it was up to Willem and Almaria to take care of the kids there.
  • Physical God: Revealed to be a Visitor similar to Elq but with different origins and goals.
  • Really 700 Years Old: Doesn't look like he's aged a day in present-time Règles Aile. Judging by how long he’s known Jade Nail it’s quite possible he’s the oldest character in the series.
  • Reality Warper: His curse casting abilities are unparalleled, with Carma even remarking that such abilities could easily be used to erase entire concepts from existence or change the very nature of one’s being. Apparently, he can only use these powers a limited number of times on a world before he has to leave.
  • Retired Badass: He used to be a Regal Brave before retiring to run an orphanage. It’s all the more impressive when you consider the fact that the position of Regal Brave is all but implied to be a death sentence for anyone that takes it.
  • Tragic Hero: Heavily implied. He was a previous holder of Seniorious. One character suggested that both Nils and Lillia fight for similar reasons. This might also explain his reluctance to train Willem; he didn’t want his foster son going down the same path.
  • Underestimating Badassery: None of his charges (including and especially Willem) believes his claims that he was once a Regal Brave.
  • Vague Age: Trying to guess his age is a futile endeavor. Lillia swears he hasn’t aged a day since she met him and even looks younger somehow. This is probably due to him being a Visitor.
  • Well-Intentioned Extremist: He founded True World with the intent of stopping the coming destruction of the world. Unfortunately, some of its members were a bit too radical and their actions resulted in the entire organization being labelled as an evil cult.

Almaria Duffner (The Daughter)
Voiced by: Satomi Sato (Japanese), Bryn Apprill (English)

One of the oldest children of the orphanage Willem comes from, who made a promise with Willem to wait for his return.

  • Affectionate Nickname: Willem lovingly refers to her as "Al".
  • And I Must Scream: She appears to be somewhat aware of the fact that she’s now a Beast, even if she prefers to pretend that everything is normal and Willem will one day return to her.
  • Betty and Veronica: She was the Betty to Lillia's Veronica and Willem's Archie in the past.
  • Clingy Jealous Girl: Is very suspicious of any girl she sees as getting too close to Willem.
  • Cool Big Sis: To the younger orphans.
  • The Dog Was the Mastermind: Willem spends the majority of volume 4 trying to discover the identity of the barrier world’s creator. Little did he know that she was right in front of him for most of the arc. It’s ironic that the architect of volume 4's conflict was the person Willem trusted most in his previous life.
  • Eldritch Abomination: Her Beast form is bizarre even by the standards of the 17 Beasts. It's unclear if the thing Willem sees in the barrier world is even Shiantor's true form or just some twisted manifestation of Almaria's psyche.
  • From Nobody to Nightmare: No one would have expected Willem's innocent childhood friend to one day become the most terrifying member of the 17 Beasts.
  • Gaslighting: She tries to do this to Willem in volume 4. Unlike most versions of this trope she doesn’t do much to interfere with Willem’s sense of normalcy, because she wants him to lower his guard and fall into the same delusion as all the other souls she’s trapped.
  • Happily Adopted: Sort of. She became the happy nice girl we see her in Willem's flashbacks after Nils and Willem took her in.
  • I Want My Beloved to Be Happy: While shocked when Willem told her that he has finally proposed marriage to someone, she immediately cheers up and tells Willem to one day bring his betrothed home so Almaria "would tease her to the best of her ability". Willem even believes that, if they had actually met, Almaria and Chtholly would have gotten along easily.
  • I Will Wait for You: Never stopped waiting for Willem to return home even after being turned into a beast.
  • The Lost Lenore: Willem loved Almaria dearly and she would always be the first thing Willem would think of whenever he'd reminisce his past in bittersweet moments.
  • My Girl Back Home: Willem tried to visit her whenever he was given time off from his duties as a Quasi-brave.
  • Nice Girl: She's very sweet and kind to everyone she knows and whenever he thinks about her, Willem reminisces about her very fondly.
  • Parental Neglect: Her father effectively abandoned her emotionally, and eventually literally after her mother died.
  • Patient Childhood Love Interest: Her last conversation with Willem before he went off to war strongly hints at this. She sounded almost disappointed that he asked for butter cake rather than proposing to her. This trope is later taken to a nightmarish extreme when she becomes Shiantor; with her constructing a fantasy world from thousands of trapped souls all so she could one day make Willem a PERMANENT resident of her fake Gomag.
  • Promotion to Parent: Takes care of the younger children at the orphanage.
  • The Reveal: One of the biggest reveals in the series is that she’s the Lamenting First Beast. This doesn’t occur in the anime version, likely because the author thought the series would be much shorter when they first wrote the light novel.
  • Supreme Chef: The light novels reveal she was one. Given that she's effectively "the mother" in her and Willem's orphanage despite the light novels referring to her as "the daughter" before her name was revealed, it makes sense that she should be one.
  • Team Mom: She's the oldest of the orphans next to Willem and is usually the one who took care of them in his and Nils's stead at home.
  • Tomato Surprise: The end of volume 1 reveals that she's Shiantor the Lamenting First Beast. This revelation about her in the first volume is one huge Foreshadowing for one of the series' biggest twists in later volumes.
  • Tragic Villain: All she ever wanted was for Willem to return home. This hopeful delusion led to her trapping thousands of souls in a recreation of Gomag for over 500 years after she became the First Beast. Willem finally snaps her out of this by admitting he couldn't keep his promise, allowing her to pass on peacefully.
  • Walking Spoiler: The Reveal about her and Shiantor being one and the same is a major hint that the Beasts were once human.
  • Yaoi Fangirl: Volume 4 heavily implies that she wouldn't mind it if Willem and Souwong got together. Or she just mistook Souwong for a girl, which wouldn’t be surprising given how Souwong used to look.

Theodore Brickroad

A level 8 Adventurer from Gomag and Willem's self-described "friend".

  • Be Careful What You Wish For: Lampshaded. He tells Willem that he always wanted to become more “dangerous” in order to impress Almaria, but he never thought that would involve him turning into a Beast.
  • Butt-Monkey: Willem treats him as little more than a pest, even outright ignoring him at times.
  • Chekhov's Gunman: In the barrier world, it was Ted who eventually allowed Willem and Elq to meet, having taken the latter to the orphanage during the awakening of the Beasts.
  • Early-Bird Cameo: He’s mentioned by name in the prologue of the first volume, but doesn’t get properly introduced until the fourth volume.
  • Hopeless Suitor: Is infatuated with Almaria. Unfortunately, her "father" is not so fond of him, and Almaria has her eyes set on someone else.
  • My Friends... and Zoidberg: Willem often describes Ted in this manner.
  • Not So Different: His feelings of inferiority towards Willem aren’t all that different from Willem’s feelings towards his fellow Braves.
  • Offscreen Moment of Awesome: Despite his low-level rank he managed to somehow retrieve a Carillon for Willem in a town that had already been overrun by Beasts.
  • Perpetual Smiler: He never lets up his stupid grin, even after realizing he's begun turning into a beast.
  • I'm Standing Right Here: Willem tends to intentionally ignore Ted during conversations.
  • What You Are in the Dark: The only reason he became an adventurer was so that he could impress Almaria. Yet when the 17 Beasts start destroying Gomag he puts the lives of others ahead of his own safety. Although he eventually starts turning into a Beast himself, his actions give Willem and Nephren a fighting chance. In the end even Willem admits that he underestimated the guy.
  • Zombie Infectee: He begins to hear a nostalgic song and see visions of an ashen world shortly after delivering the Carillon to Willem. He opts to spend his last moments getting as far away from the orphanage as possible so he won't threaten the others when he turns into a beast.

Marguerite Medicis

A young girl from an aristocratic family who is engaged to Feodor Jessman.

  • Because You Were Nice to Me: For most of her life she was scorned by her family for her mixed ancestry, so when Feodor showed her genuine kindness in their first meeting it was enough for her to start falling in love.
  • Cat Girl: She has a few catlike features due to some Beastfolk ancestry in her family's past that manifested in her generation.
  • Childhood Marriage Promise: She was engaged to Feodor when she was younger.
  • Half-Breed Discrimination: Her family saw her mixed ancestry as an embarrassment and kept her isolated from society for most of her life.
  • Insecure Love Interest: Even after discovering that Feodor also survived the destruction of Island 13 she still tries to avoid officially reuniting with him. This is partly due to her feeling responsible for the accidental release of Croyance on Island 38 during the festival.
  • Irony: Feodor notes the irony of the fact that she's ashamed of having animal features in a world in which humanlike races are looked down upon by society.
  • Little Bit Beastly: She has cat ears and a tail despite both her parents being disfeatured.
  • Sheltered Aristocrat: She initially knows little about the outside world due to her sheltered upbringing.
  • Took a Level in Badass: She now works as an assassin, a far cry from her former lifestyle.
  • Unwitting Instigator of Doom: One of her missions goes south, which leads to a sample of Croyance being unintentionally released on Island 38. In the confusion Apple is swallowed up by the Beast, causing her to unwittingly self-destruct. Feodor and Ryehl are almost killed in the ensuing blast; only being saved by Lakhesh’s extreme Venenum overuse. That overuse, in turn, causes Lakhesh’s personality to fragment, further increasing the toll of the attack.
  • You No Take Candle: She has an extremely odd manner of speaking.

    The 17 Beasts (HEAVY SPOILERS!) 
The 17 Beasts who ravaged the surface lands and drove the surviving species to the Floating Islands Règles Aile after the Emnetwihts' extinction. They continue to dwell in the surface lands and constantly terrorize any and all who attempt to explore what remained of the surface. Noteworthy here is that the "17" in their collective name doesn't refer to them being only seventeen in number, but to the fact that there are 17 types of Beasts out there, all of whom are massive in sizes and shapes.
  • Always a Bigger Fish: They are undoubtedly the biggest fish in the series. When they first appeared many of the stronger races tried to hold their own against the Beasts. All of them were wiped out in less time than it took for them to exterminate humanity.
  • Always Chaotic Evil: Subverted. It’s implied that they’re actually peaceful by nature and that they just wish to be left alone. However, the Visitors disturbed their serene lifestyle when they altered the world for their own ends. As a result the Beasts developed a burning hatred for all other kinds of life and they now instinctively attack anything that’s not a Beast on sight.
  • And I Must Scream: If Shiantor is anything, it's possible that some of the Beasts still retain some semblance of their memories and humanity from the time they still lived as emnetwihts, though they're now mostly driven by their monstrous instincts.
  • Berserk Button: Anything that’s not beast, ash, or sand must be destroyed.
  • Bizarre Alien Biology: They’re not life forms in the conventional sense. They apparently don’t need food and are effectively immortal.
  • Bizarre Alien Psychology: Their thought process is completely incomprehensible to other forms of life. As a result any form of communication with them is next to impossible. Willem decides to give it a try anyway and is implied to have succeeded.
  • The Dreaded:
    • Shiantor the Lamenting First Beast is this as it is the most powerful Beast known to be recorded. In fact, not one person has survived a single encounter with this particular Beast and whenever its presence is somewhere in the area, the army is advised to avoid it.
    • Vincra the 14th Beast would probably rival Shiantor in terms of dread if it wasn’t for the fact that most information about it is highly classified. It’s ability to corrupt the minds of those it comes into contact with makes it especially dangerous. Even fairies, the Island’s one effective defense against Beasts, can easily be brought under its control. The elaborate “tuning” process all fairies undergo when they come of age is actually just a means of ensuring that they’re incompatible with the sword the Beast is currently sealed in. Otherwise, they risk having a repeat of the infamous Night of Mornēn Incident, where the Beast’s malevolent will took over a young fairy ,Elba, and caused an outbreak of homicidal insanity that led to the destruction of an entire island.
  • Eldritch Abomination: All of them.
  • Expy:
    • Their backstory and origin is very similar to the Shades, in that in spite of monstrous appearances, their origin is much more human then one would expect.
    • They have a number of similarities with the Shoggoths from H.P. Lovecraft’s “At the Mountains of Madness”. Notably their relation to the Visitors is similar to the one between the Shoggoths and the Elder Things. In both cases an advanced extraterrestrial civilization used an initially non-sentient race to build a new world for them to inhabit. The Shoggoths eventually gained intelligence and revolted against the Elder Ones, much in the same way the Beasts became aware of what the Visitors has done to their world and subsequently went on to destroy anything associated with the extraterrestrials. Shoggoths are also implied to be the origin of all life on earth; similar to how the Beasts were used to create the various races in Suka Suka. Given the many references to Lovecraft in Kareno’s books, these similarities might be intentional.
  • Hidden Depths: In their natural habitat they are surprisingly docile. Nephren hypothesizes that their hostility to other life forms is due to them disturbing this natural tranquility.
  • Horde of Alien Locusts: Vast swarms of these creatures seemingly came out of nowhere 500 years ago and bulldozed anything that stood in their way. Though from their perspective they were only pushing back the “real” invaders that had infested their former home.
  • Hostile Terraforming: Once the Beasts enter an area they immediately start killing off all non-Beast life and begin transforming the environment into an ashen desert.
  • It Can Think: There are several times in the series where the Beasts show signs intelligence. Most notably they have shown the ability to work together and maybe even strategize. There are even some Beasts like Shiantor and Vincra that may have even retained some of their former human intelligence.
  • Man-Eating Plant: The Timere are gigantic plant-like abominations who kill and devour anything they lay their eyes on.
  • Names to Run Away from Really Fast: Hearing any one of their names is enough to strike fear into the hearts of Règles Aile’s citizens. How fast and how far you need to run depends on the Beast.
  • Not Evil, Just Misunderstood: At first glance they appear to be nothing more than mindless monsters that destroy without rhyme or reason. However, Willem eventually learns their true motivations after awakening his beast side. They are simply trying to reclaim their former home, making them Not So Different from the other races. Unfortunately, due to their different nature they are incapable of recognizing the suffering caused by the “reclamation” of their home. Willem resolves to rectify this by finding a way to communicate with the Beasts and forge some sort of understanding with them. The ending implies that he might have succeeded.
  • Not Quite Flight: Why the Timere are the only Beasts to watch out for in Règles Aile. They can split off parts of themselves and release them into the air, and those pieces can reach the islands then grow into new Timere.
  • Run or Die: Running is usually the only option when dealing with the Beasts. Especially Shiantor.
  • Tomato in the Mirror: They were formerly known as the human race.
  • Tragic Villain: It's later revealed that they were turned into humans against their will by the Visitors. They were actually the original inhabitants of the planet. The barren wasteland that now covers the surface is actually a recreation of that primordial world. The pain of losing that home has twisted them into the violent monsters they are in the present.
  • You Are Number 6: In casual conversations, the Beasts are simply referred to by number.

Chanteuse: The First Beast Who Laments At The Moon / Almaria Duffner / "Shiantor" (Fan Translated Name)

  • And I Must Scream: La Chanteuse still retain some semblance of its memories and humanity from the time it was Almaria Duffner.
  • The Dreaded: La Chanteuse is this, as it is the most powerful Beast ever recorded. In fact, not one person has survived a single encounter with this particular Beast and whenever its presence is somewhere in the area, the army is advised to avoid it.
  • Dream World: La Chanteuse has the ability to create illusions and dream worlds to lull its prey into a false sense of security. Almaria Duffner used this ability to recreate Gomag city using the memories of all the souls that she had entrapped within her.
  • Eldritch Abomination: Its Beast form which is of a massive black crystal pillar with Almaria's body coming out of the centre of it is bizarre even by the standards of the 17 Beasts. What's worst is that one can see the dried-up corpses and souls of the people trapped within it. Even Willem can't tell if the thing he sees in the barrier world is even Shiantor’s true form or just some twisted manifestation of Almaria’s psyche.
  • Enthralling Siren: Chanteuse is basically this, as it uses its song to lure in its prey before trapping them and devouring them into its dream world.
  • It Can Think: It has been implied over several times throughout the series that La Chanteuse has still maintained some semblance of its former mind as Almaria Duffner.
  • Meaningful Name: La Chanteuse means "The Songstress" in French which refers to Chanteuse's ability to draw in its prey with its song.
  • Single Specimen Species: La Chanteuse is the only one of its kind. It is a solitary beast who pines for a certain someone Willem to come back to it.

  • Super-Powered Evil Side: La Chanteuse becomes this to Willem and Nephren after volume 4. Nephren can tolerate hers, however, Willem at best can only control its powers for five minutes, after which he’ll be completely taken over by the beast. Oddly enough he manages to come to an understanding with the beast while they’re both sealed with Seniorious’ hex.
  • Took a Level in Kindness: By the time of Suka Moka it has mellowed out a great deal thanks to Willem's influence and is willing to help out Feodor for Willem's sake.
  • Walking Spoiler: La Chanteuse's real name is revealed via foreshadowing in the last episode of the anime series, as the title of the book that Rhantolk was reading is titled "La Chanteuse" which means "The Songstress" in French.

  • It Can Think: They have shown the ability to prioritize particularly dangerous targets and work together with other members of their kind to destroy them.
  • Spike Shooter: At first glance, it looks like a big snake, however instead of scales, it has countless needles growing out of the surface of its body, it also has no head or tail.
  • Flechette Storm: Because of its needles, Aurora can bombard a target with them in a spam attack to annihilate its enemies.
  • Zerg Rush: Aurora are the weakest type of Beast seen so far. However, they also happen to be the most numerous type. If they are faced with a particularly tough opponent they’re not afraid to call up other members of their kind and overwhelm them with raw numbers.

Legitimitate: The Fourth Beast Who Twists As Its Swallows

  • Hyper-Awareness: Legitimitates are blind creatures who can sense their prey just by hearing or sensing the vibrational waves made from the voices, sounds and movements that they make.
  • I Work Alone: Legitimitates tend to live away from their own species.

Materno: The Fifth Beast Who Spreads Out Widely

  • Acid Pool: Materno attacks by melting everything into a clear blue liquid.
  • Small Role, Big Impact: This Beast has so far only been mentioned a few times in Suka Moka. However, its destruction of Elpis plays a major role in Feodor's backstory.

Timere: The Sixth Beast Who Hides Deeply

  • Man-Eating Plant: The Timere are gigantic plant-like abominations who kill and devour anything they lay their eyes on. They are similar to dandelions in that they can release spores on the wind.
  • Marathon Boss: A non-video game example, the Timere that invaded the 15th Island which took the Guardian Wings nearly half a month to deal with, and was even then only defeated by Limeskin choosing to sink the island.
  • Not Quite Flight: Why the Timere are the only Beasts to watch out for in Règles Aile. They can split off parts of themselves and release them into the air, and those pieces can reach the islands then grow into new Timere.

Croyance: The Eleventh Beast Who Remains Rooted

  • Crystal Landscape This is what Island 39 turned into after it was devoured by Croyance.
  • Eldritch Abomination: Croyance takes the form of a mass of constantly growing black crystals. It “assimilates and gets bigger with each thing it touches” and “proceeds to absorb and assimilate any shock to it.”
  • Mighty Glacier: This Beast moves at a glacial pace as it absorbs its surroundings. However, it makes up for this by being all but immune to physical attacks. Reports from battles with this Beast make it damn clear that nothing the military has in their conventional arsenal can put a scratch on it.
  • Silicon-Based Life: In Suka Moka, Croyance is described to be a huge black crystal which slowly assimilates everything in its path.
  • You Will Be Assimilated: Croyance's main method of attack is to assimilate everything in its path. It will also absorb anything that tries to attack it and once it starts absorbing someone, it won't let go. The only way to save someone is to amputate the trapped limb. Additionally, it also has trouble assimilating rock and other natural plant life.

Vincra: The Fourteenth Beast Who Binds Brightly

  • Brainwashed and Crazy: Vincra has the ability to control the minds of others and turn them into its insane puppets.
  • Greater-Scope Villain: Vincra is either directly or indirectly responsible for much of the suffering in Suka Moka.
  • It Can Think: Several times throughout Suka Moka it has been shown that Vincra may have even retained some of its former human intelligence.
  • Karmic Death: Vincra wouldn’t even have existed if wasn’t for Helva’s refusal to become an Imp, which resulted in her reverting to her Beast form like the rest of humanity. It is therefore fitting that the Beast’s reign of terror was ultimately brought to a close by a lowly Imp.
  • Revenge Before Reason: Jade Nail offered to turn Helva into an Imp so she wouldn’t devolve into a Beast like the rest of her species. She refused, opting to continue the pointless conflict between humans and Visitors. This only resulted in Jade Nail’s death and her own transformation into the 14th Beast. Both of these events would cause untold suffering later down the road.
  • Was Once a Man: It is revealed in Suka Moka Volume 6 that Vincra was originally a young Ementwiht quasi-brave girl named Helva T. Lontis who was the former owner of Mornēn until she started turning into a Beast. Her last act as a human was to kill Jade Nail, the Poteau who started the war with the Ementwihts

How well does it match the trope?
