Voiced by: Aki Toyosaki (Japanese), Jamie Marchi (English)
A rookie goddess of healing, who is tasked with saving Gaeabrande.
- Absolute Cleavage: Her dress invokes this; it seems to be the norm where she comes from.
- Affectionate Nickname: Everyone just calls her "Rista", for short.
- Aren't You Going to Ravish Me?:
- When Seiya states that he has one condition before helping Rista, he takes his off his shirt. Rista, who is sitting on the bed, imagines a romantic encounter while very quietly stating how a god and a human can't have a relationship. She then gets annoyed when it turns out the request is for him to work out until he's ready.
- When she finds out that Seiya snuck into her room to take 100 of her hairs to craft another powerful sword, she demands to know if he did "this and that" to her while she was asleep. When he makes it clear that he didn't, she becomes upset.
- Biting the Handkerchief: Rista does this after Seiya leaves her in the Roseguard castle to rest, thinking that she's inferior to medicinal herbs.
- Blatant Lies: Annoyed at a tailor's sarcastic tone and ridiculous swimsuit offers, Rista, without hesitation, tells her that Seiya is her boyfriend. That's not currently correct though, as romantic relationship is a taboo in the Divine Realm. This is subverted once you realize that Rista is the reincarnation of Seiya's lover.
- Boring, but Practical: Her healing magic is slower than high-tier medicinal herbs, but herbs can't re-attach lost limbs while she can do so, even with her powers weakened.
- Butt-Monkey: Seiya compares her to a medicinal herb and due to her power being nerfed in the mortal realms, she actually does end up less powerful than the strongest healing items. Seiya also tends to remove her hair without permission in order to use it as a crafting ingredient.
- Chekhov's Gunman: It's revealed that if a hero dies while trying to save a world, they'll simply return where they came from without any memories of their time in that world. This sets up a major reveal later.
- Clingy Jealous Girl: She gets jealous when she catches Seiya in bed with Valkyrie, not realizing that this is a way for the Valkyrie to teach Seiya how to use Valhalla's Gate.
- Cloudcuckoolander's Minder: Almost everything that Seiya does weird will be rejected or rebutted by her:
- Seiya has a weird habit or Running Gag of wanting spares for his weapons and equipment. She's there to make sure that they don't spend too much money.
- Due to being overly cautious, Seiya is mostly stoic and doesn't easily trust strangers. This makes him forget how to converse politely. Rista is there to scold him for his rudeness or to ask their inquiries in a more polite manner in his behalf.
- When Seiya repeatedly slaps Rosalie (in self-defense), Rista decries his lack of "feminism". Once they return to the Divine Realm, she tells him to stop doing that.
- Covert Pervert: She may try to keep up the appearance of a respectable goddess, but it's blatantly clear she wants to jump Seiya despite the rules.
- Crouching Moron, Hidden Badass: Despite going through a number of frustrating and humiliating situations, her healing is actually very powerful when she's not limited by the gods' rules. After Seiya's first use of Valhalla's Gate, Rista manages to heal him so he can survive the backlash. Keep in mind that Valkyrie had to buff herself to max stats in order to survive the recoil of that technique. In the Ixphoria arc, she turns out to be an Instant Expert at anti-curse techniques and kills one of the enemy generals with a light spell. Even when weakened due to the gods' rules, she can heal severed limbs.
- Distracted by the Sexy: Seiya drives her mad with his personality, but she can't help but get hot and bothered when he is shirtless or when she's close to him.
- Double Entendre: Says this innuendo after a tailor offered her to buy underwear that would expose the crotch of her "boyfriend" Seiya:If Seiya wears this, his elephant will be fully visible.
- Dull Eyes of Unhappiness: After she sees Seiya and Valkyrie naked in bed, which makes him learn a Destruction Art skill, she becomes overly jealous, desperate and shocked, to the point that her eyes are drawn in this way.
- Female Gaze: Most of her first impressions with Seiya are about being stunned with his appearance or muscular build. In particular, Rista barged in the room without knocking, only to catch sight of his six-pack abs.
- Freudian Slip:
- Rista just can't resist blurting out her perverted thoughts about Seiya even in a state of emergency, when Aria feared that Mitis might sexually harass him:I can't let this one-in-ten-billion-people level genius get kicked out because he got in bed with a goddess!! If it has to be a goddess, why not me... Wait, that's not what I wanted to say!
- Rista accidentally blurted out that the Divine Realm's shops are better than the clothing shop in Gaeabrande. This annoys the female shopkeeper to the point where she sarcastically mocks Rista by offering her ridiculous swimwear that are too risqué.
- Rista just can't resist blurting out her perverted thoughts about Seiya even in a state of emergency, when Aria feared that Mitis might sexually harass him:
- Gratuitous English: In the Japanese version, she says "Oh, six pack!" in a stunned state when she sees Seiya's abs and "Oh, sexy!" when Seiya comes out from the shower.
- Has a Type: She likes tall, muscle toned men with dark hair. Seiya fits this to a T. The reason why is because she subconsciously remembers that she was his lover in her previous life.
- She describes Aria as the ideal goddess and regularly visits her for advice.
- To a lesser extent, she gains more faith in Seiya when his preparations allow him to defeat several impossibly difficult foes.
- Heroic BSoD: She becomes depressed after Seiya's supposed death from saving Gaeabrande, to the point where she lacks her usual cheerful personality once she returns to the Divine Realm, as she locks herself in her room for days, and leaves her hair in a messy state. Fortunately, all of the other deities try to raise her spirits once again. She finally breaks out of her depression once Ishtar reveals that Seiya is still alive, he's just sent back to Earth and can be summoned once again.
- Hot God: She's pretty cute and buxom, with her outfit leaving little to the imagination.
- Imagine Spot: She easily fell for Seiya's looks, and also easily misinterprets his requests as romantic advances. Cue some of Rista's imaginations about having to kiss him... until she remembers that romance between gods and mortals are forbidden.
- Innocently Insensitive:
- Rista points out that Aria only failed to save one world, but Aria reminds her that the world is all its residents have.
- When Rista tries to convince Seiya to recruit the dragonkin duo, he states they wouldn't be much help in combat. Rista then states that they can be used as key items to get past any obstacle that requires their lineage, but the duo are offended to be considered "items."
- Lovable Sex Maniac: Her perverted thoughts about Seiya rise to its peak once she decides to buy underwear for Seiya that will expose his crotch.
- Meaningful Name: Her name sounds an awful lot like "Restart", which is fitting, since that's basically what happened to her when she lost her memories and became a goddess.
- Meta Girl: Most of her Inner Monologue comments on the absurd tactics or tropes that Seiya used recently.
- Ms. Fanservice: She's this thanks to her outfit showing her cleavage.
- Mundane Utility: She makes a doll out of her hair just so she can give it to Seiya as a synthesis material.
- New Meat: She's only saved a few low-difficulty worlds, and is considered inexperienced for a goddess.
- Nice Job Breaking It, Hero!: When attempting to change the location of the portal in the Divine Realm, she accidentally allows a werewolf demon to go through the portal. The werewolf then inflicts a confusion ailment on Seiya, causing the hero to regress back to his reckless ways.
- Noodle Incident: She mentions that she once summoned a Martian as a hero for a low difficulty world and had to get them up to speed with the situation.
- Offscreen Moment of Awesome: She managed to save a few worlds before receiving the mission to save Gaeabrande. Some of her summoned heroes were unfamiliar with Isekai and JRPG mechanics, but she still managed to teach them enough to save those worlds.
- The Pig-Pen: Downplayed. Other characters often claim she has a sour body odor. This actually saves her in the Ixphoria arc, where a demon refuses to eat her because of her odor.
- Punny Name: If it isn't obvious enough, "Ristarte" is just the Engrish pronunciation of the word "Restart".
- Reincarnation: Combined with Deity of Human Origin. She's the reincarnation of Princess Tiana, Seiya's lover from Ixphoria.
- Screw the Rules, I'm Doing What's Right!: After learning of Seiya's and her past, she willingly disobeys the Divine Realm's rules to save Seiya.
- Slapstick Knows No Gender: When some silly screwball moment happens, she's often on the receiving end of it.
- Stripperiffic: Her outfit is very revealing, which Seiya lampshades early on. Rista protests that her magic lets other people see her dressed more modestly.
- Supporting Protagonist: She's the main viewpoint character, but due to laws restricting the gods in mortal realms, her summoned hero, Seiya, drives more of the plot.
- Tears of Joy: This is her reaction when she finds out she's allowed to summon Seiya again after Gaeabrande's Demon Lord is defeated.
- Tempting Fate: In the first manga volume's short story, Rista is angered by an archangel who criticized her lack of progress. In response, she yells "I'll take any A- or S-ranked world you throw at me!" She soon gets assigned to the S-Ranked world, Gaeabrande.
- Tsundere: She has a crush on Seiya, but at the same time, is exasperated by his cautious personality and rude behavior.
- Underestimating Badassery:
- Her first impression of Seiya was the result of this. Rista thought that he was a coward when he was just being cautious. When she thought that he is backing away from saving Edona, he just needed some time to level-grind. And when she thought that he couldn't take out Chaos Machina's bull form in his current state, it was when she realized that Seiya was just faking his real, higher stats.
- She initially believes the tactics she used in low difficulty worlds, such as level grinding in a weak area, will work against the demons of Gaeabrande and that Seiya's cautiousness is overkill. She's proven wrong when the demons of Gaeabrande turn out to be wise to the tactics that defeated their brethren in other worlds.
- Unishment: For the "crime" of using her goddess abilities to directly interfere with the final battle between Seiya and Gaeabrande's Demon Lord, Rista is sentenced to save the SS-ranked world Ixphoria, the original world she lived as a mortal. In addition, she is told that since the Demon Lord's Chain Destruction was destroyed in the final battle, she is free to summon Seiya once again to aid her.
- Vapor Wear: It's quite obvious from a glance that her outfit doesn't have any form of breast support beyond her top. This becomes a detriment when she ends up getting dragged along by Seiya at high speeds in order to quickly get somewhere, resulting in her breasts popping out.
- Victoria's Secret Compartment: She places a piece of chalk for summoning circles there in the anime.
- White Magician Girl: Downplayed. She specializes in healing and usually means well, but she can also be petty when arguing with Seiya. There's a justification for this as well. Before she became the Goddess of Healing, she was the healer in Seiya's party back in Ixphoria.
- Wild Take: Rista's exaggerated facial expressions would qualify.
Voiced by: Yuichiro Umehara (Japanese), Anthony Bowling (English)
The titular cautious hero, who takes excessive precautions in his quest despite his high stat growth.
- The Ace: The exact reason Rista chose him for S-ranked world Gaeabrande. His baseline stats were far higher than the other potential heroes, he's an Instant Expert that learns the skills from some of the most powerful gods in the the Divine Realm in days, he always comes out on top due to his Crazy-Prepared nature and has multiple goddess falling for him. Even in Ixphoria, he was stated by Aria to always win despite being underleveled and never having a plan due to his natural talent as a fighter.
- Ain't Too Proud to Beg: He even begged the Demon Lord of Ixphoria not to kill Tiana and their unborn baby.
- Always Save the Girl: When given the choice, he'll prioritize saving his friends over the world. He passes up on Igzasion in favor of saving Elulu from her sacrifice, despite how doing so means he loses the only weapon that can kill the Demon Lord.
- Attack Reflector: Counter Break is a destruction technique that reflects the damage back at the attacker. In this case, when Seiya lost his arm, this ability allowed him to also cut off Wohlks' arm without the latter realizing it.
- Automatic Crossbows: Technically it's a magic bow, but Seiya fires his magic bow at Beel Bub's flies so quickly that it's essentially this. Since his arrows are flying much faster than the ones used by Rosalie's archers, the normally fast flies have no time to react before dropping dead out of the sky as Seiya shoots them all down.
- Awesome, but Impractical: His Meteor Strike spell is capable of destroying entire armies just one cast, but its capacity for incredible destruction means it can't be used anywhere else other than an open plain far away from civilization. Seiya never uses it again after wiping out Deathmagla's undead army for this reason.
- Badass Baritone: Has a deep, strong voice to go with his power and serious demeanor courtesy of Yuichiro Umehara.
- Badass Cape: He used to wear a red cape in his previous life on Ixphoria.
- Berserk Button: He doesn't take kindly to those who harm children. The first two enemy generals find this out the hard way when they taunt Seiya by threatening to harm a child, or actually torturing them in Mash's case.
- Big "NO!": Screams this when the Demon Lord of Ixphoria is about to eat Tiana and their unborn baby.
- Bishie Sparkle: From Rista's point of view, he is sometimes shown with this, signifying her crush on him.
- The Blacksmith: In his efforts to be as prepared for any eventuality as he can, he uses his Combine skill to create weapons, armor, and magical accessories using whatever he can get his hands on, especially if the materials are high quality (the hair of Rista, a goddess, being a commonly used one). Often veers into Ultimate Blacksmith, as he has a keen eye for taking said high quality materials and making the best equipment that could ever be made out of what he has on hand at the time.
- Boring, but Practical: His first method of Level Grinding and preparing himself to fight Chaos Machina again is to simply exercise in his room. Sure enough, even Rista is surprised when he did gain some levels and skills just by doing this mundane task instead of the typical way of gaining EXP in an RPG-Mechanics Verse, which is killing monsters.
- Boxing Lessons for Superman: He insists on learning as many techniques from the gods as he can, becoming skilled at swordsmanship, archery, and destruction techniques in the process. This is because he's worried that he'll still be weaker than the stronger demons at his level cap, meaning he needs to learn additional skills to compensate.
- Brutal Honesty: The man never minces his words regardless of how insulting they could be, even when addressing gods and royalty. Someone's offended? Tough break.
- Buffy Speak: Seiya calls the Transform Automatic Garuda skill as "turn into birds and come back, boom".
- Cast from Lifespan: Valhalla's Gate is cast in exchange of one's own life. The user could survive if they have maxed stats though. Valhalla's Gate Another takes his life as payment and not even a fully powered healing goddess can stop that.
- Catchphrase: When he feels ready to take on the next part of his quest, he'll say "perfectly prepared." His catchphrase used to be "gonna be okay" until Ixphoria's Demon Lord made the situation not okay.
- Chaste Hero: Rista and Adenela fell in love with him (much more in the latter's case), but Seiya just nonchalantly dismisses Rista's advances and outright reject's Adenela's cake. This was averted in Ixphoria, where he was in a relationship with Tiana.
- Chick Magnet: Rista even puts a lampshade on this as she calls Seiya a "Goddess-Killer" after realizing that Adenela fell in love with him without Seiya even realizing it.
- Colony Drop: He can use a spell called Meteor Strike to summon a meteor capable of wiping out tens of thousands of enemies. He also has enough MP reserves to spam it all day.
- Combat Sadomasochist: Way back in the past, even if there's a hole in his chest and when he had only 2 HP left, he was still thrilled and happy to charge towards the enemy.
- The Comically Serious: Most of the humor in the series is derived from Seiya's completely blank, serious personality being at odds to the ridiculousness around him (especially Rista's reactions).
- He's a strong believer in being overleveled against all foes and tends to stock more armor and items than he needs.
- After knowing that there are beings like Rista who can scan a hero's status parameters, he decides to use the Fake Out skill in order to fake his parameters in case the enemies also have a scanning ability like Rista. He's proven right when Chaos Machina does read his stats mid-fight.
- Cruel to Be Kind: He intentionally pushes his allies away and refuses their help, since he doesn't want to risk them dying in battle. Aria later reveals to Rista that she summoned Seiya save Ixphoria 100 years back. Unfortunately, he was reckless and charged into battle, hoping things worked out. It does until they defeat the Demon Lord, who turns out to have a second life, and kills the exhausted party by eating them, including Tiana, Seiya's healer and lover who was pregnant at the time she was eaten. Though neither he, nor Rista, who is the reincarnation of Tiana, remember anything from Ixphoria, his extreme guilt at not planning ahead and preparing for contingencies carried over and triggered his "overly cautious" status.
- Dangerous Forbidden Technique: In the final battle in Gaeabrande, Seiya reveals that he has an even stronger version of Valhalla's Gate called Valhalla's Gate Another that creates a larger gate capable of withstanding Gaeabrande's Demon Lord's final attack, which was said by Rista to have twice the power needed to end the world. However, the cost is Seiya's life, which causes Seiya's body to break apart at such a rate that even Rista's full healing powers can't stop.
- Dark and Troubled Past: He had a wife, who was pregnant, in the previous world he was summoned, Ixphoria. He was very headstrong and basically bulldozed his way to the Demon Lord. He killed the Demon Lord without realizing that he had another life; cue the Demon Lord annihilating his entire party, which consisted of his friends and his wife. After Colt and Aria are eaten, Seiya literally begs the Demon Lord not to kill Tiana. However, the Demon Lord ignores him completely and proceeds to tear the baby from his wife's womb and eat it, along with his wife afterward. Seiya was sent back to Japan, forgetting everything that happened. However, the cautious personality was engraved into his soul. The goddess who summoned him this time, Rista, is his wife's reincarnation.
- Death of a Thousand Cuts: The Gunshot Sword skill that he learned from Adenela is a rapid-fire series of stabs and slashes that evoke the speed of firearms.
- Destructive Savior: His tactic of burning the enemies' remains tends to result in property damage due to the scale of his fire spells.
- Disappears into Light: He vanishes into blue light just as his body can no longer take the punishment for summoning two Valhalla's Gates.
- Dishing Out Dirt: He uses the class change system in Ixphoria to change his main element to earth, allowing him to create snake golems and manipulate the ground to create passageways.
- Dissonant Serenity: He can be calm during situations where an ordinary person would panic, or his demeanor wouldn't fit in the gravity of the situation. Rista also puts some Lampshade Hanging on these scenes to put an emphasis on his unexpected reactions:
- He quickly counters and slaps Rosalie's face while keeping his usual calm and stoic face. Rista then decries his "lack of feminism".
- While patting Adenela's head in order to calm her down, Seiya calls her an "eyesore" and that she should leave. Adenela happily agreed, because she's that just in love with Seiya despite him having said mean things to her.
- Doom Magnet: Played for laughs when he's convinced he's become one due to holding onto a good luck charm given to him by Nina in Edona, which he thinks is a cursed item that attracts high-level enemies due to Chaos Machina ambushing him soon after. He decides to hold onto it anyway because it's easier for his enemies to come to him. Keep in mind this is all over a charm made by a small child.
- Double Tap: Seiya burns his enemies' corpses just to ensure that they are dead.
- Dual Wielding: Uses two Dragon Killer swords when he had to quickly defeat the Great Mother of Dragons.
- Establishing Character Moment: As soon as Seiya arrives, he reacts with immediate suspicion towards Rista and her claims, and then outright refuses to step foot in Gaeabrande until he's spent a week working out to level grind in safety.
- Flaming Sword: His Phoenix Overdrive skill gives this, which he uses to kill Chaos Machina.
- Flight: He has the Flight ability and can travel in air faster than Rista, but not as fast as Beel Bub. He loses Flight in Ixphoria, due to that world having different rules and available abilities.
- Fling a Light into the Future: He did this to himself after failing at Ixphoria by leaving a message on the Properties screen.
- Foil: Seiya's cautiousness is in contrast to Rosalie's recklessness. But when his backstory is revealed, this gets subverted and Elulu even lampshades that Seiya's old personality is like Rosalie's.
- When he says "Properties," it's seemingly for no reason other than not trusting Rista. It's because he left a message for himself on said screen, which warned him to always be prepared, after what happened in Ixphoria.
- Volume 1's afterword describes two types of players: the more casual player who plays through the story without leveling much and the cautious player who overprepares. Seiya is an obvious parody of the latter type of player, but Ishtar reveals that he used to be a comically impatient and reckless hero who never grinds, resulting in his death in Ixphoria, making him a dark parody of the former type of player.
- Seiya outright hates Rosalie's recklessness. There is a deep-seated reason for this: It reminds him of his past, reckless self.
- Just after being defeated, Wohlks wonders if Seiya has faced death countless times before, possibly the reason why he's so cautious. He's right, that happened way back in Ixphoria.
- Freudian Excuse: Seiya's tendency to use There Is No Kill Like Overkill by repeating blowing up the ashes and corpses of the Demon Lord's minions at first seems comical due to his nature of being overly cautious. However, this came about because when he was in Ixphoria 100 years prior, his lack of planning and gathering information ahead of time meant he didn't know that the Demon Lord of that world had a second life, which revived him and let him kill off Seiya's exhausted party who barely defeated him the first time around. Consequently, this carried over when his "Overly Cautious" status showed up the next time he was summoned in Gaeabrande.
- Genre Savvy:
- Stemming from his overly cautious personality, Seiya at least tries to make some sense in explaining his decisions. Like choosing to teleport outside of Edona instead of the town center, as it would give him a chance for a sneak attack against Chaos Machina. Otherwise, the demon would just execute her hostage on the spot if she saw the protagonists teleporting nearby.
- When faced against Crossed Thanatos, an opponent that he cannot defeat head-on, Seiya runs across the Divine Realm in order to bait it and find someone capable of killing the monster. Fortunately, Valkyrie is there. In real-life MMO video game strategy, what Seiya does is called "kiting".
- Godzilla Threshold: Seiya has to learn Valhalla's Gate from Valkyrie due to a number of circumstances; he has already reached the Level Cap and can no longer improve his stats, and he lost both the Infinity +1 Sword and Infinity+1 Armor that would've made him stand a chance against the Demon Lord of Gaeabrande. At that point, he's already willing to risk his life in order to save that world.
- Good Old Fisticuffs: Though he usually uses a sword, or magic if he has time to cast it, he also trained how to fight unarmed, telling Deathmagla that his sword could get stolen, break, or just be ineffective against his current opponent.
- Gratuitous English: In the Japanese dub, his catchphrase is "ready perfectly". In his past life in Ixphoria, his catchphrase was "gonna be okay".
- Heroes Prefer Swords: Wields a sword as his go-to melee weapon.
- Heroic RRoD: Seiya slept for three days straight due to exhaustion from fighting Wohlks.
- Heroic Sacrifice: In order to kill Gaeabrande's Demon Lord, Seiya uses Valhalla's Gate twice, which results in his body disintegrating. Fortunately, the effects of Chain Destruction go away after the Demon Lord's death, allowing Seiya's real soul to survive.
- I Am Not Left-Handed: His favorite tactic is to appear weaker than his opponent to analyze their fighting style, then reveal his true power and overwhelm them.
- I Hate Past Me: It's strongly implied his rough attitude towards Rosalie is due to her resembling his past personality.
- I Was Just Passing Through: He claims he only saved Elulu from being sacrificed because he needs her to carry his stuff, but doing so means he's taking a huge risk due to lacking Igzasion. The fact that he's willing to compromise on his philosophy for Elulu shows that he cares more than he lets on.
- I Work Alone: He doesn't want his allies to fight alongside him because he fears that they could die. It's due to being traumatized from seeing his party get killed in his previous summoning. This is also the reason why he initially dismissed Mash and Elulu's offers of joining his party. Finally, Ishtar explains this to Rista, when narrating his backstory:Ishtar: Ryuuguin Seiya knew that the Demon Lord might kill you... That's why he went alone.
- Indy Ploy: Deconstructed. During his first summoning in Ixphoria, he rushed to all the enemy bosses without a strategy in mind and preferred to come up with tactics on the fly. This worked until he ran into the Demon Lord and had no way to deal with the latter's self-revival ability.
- Ineffectual Loner: He prefers to fight by himself in order to prevent casualties on his side, due to his guilt in failing to save his party in Ixphoria. His solo attempt against Gaeabrande's Demon Lord would have failed if Rista didn't follow him, since he wouldn't be able to cast Valhalla's Gate again without her healing powers.
- Instant Expert: He has a knack for learning new skills quickly, as shown by how he learns combat skills from the gods in a matter of days and gets to the point of rivaling some of his teachers. In Ixphoria, he learns how to perform class change on himself after someone does it for him once. He even materializes a fire bow right at the moment when Elulu just spoke the instructions.
- Item Crafting: Once he learned the Combine skill, he has a habit of forging new weapons and stat-changing accessories. These can also be enhanced with synthesis materials, like the hair strands of his companions.
- Jerk with a Heart of Gold: He's very insulting towards his allies, is suspicious of every new person he meets, and can come off as callous to others' feelings, but he's firmly dedicated to protecting his friends and saving the world, in that order. At the end of the first volume, he chooses to save Elulu despite losing the opportunity to gain Igzasion. Near the end of the first arc, it's revealed that he's cautious more for others' sakes than his own, due to his past recklessness getting his party killed and dooming the people of Ixphoria.
- Jerkass Has a Point:
- When Seiya refuses to stop training to go save Edona from Chaos Machina, Rista reprimands him for being a coward. Seiya points out that if he tries to save one town before he's ready and gets himself killed, then that puts the entire world at risk from the loss of their hero.
- Seiya had every right to call out Rosalie for going into battle against Beel Bub without any strategy, thus getting her soldiers killed in the process.
- Know When to Fold 'Em: He retreats with Rista once he realized that Chaos Machina is stronger than him during their first encounter. This is played with in that his actual stats are higher than Chaos Machina's displayed stats, but he realizes that she could be hiding her true power too. He also tries this when Crossed Thanatos first appears. Unfortunately for them, Crossed Thanatos simply chases them into the Divine Realm, and wreaks havoc for a while as none of the gods are able to stop it until Valkyrie is forced to step in.
- Leeroy Jenkins: During his previous life on Ixphoria, he didn't want to train, he just wanted to push forward. Somehow, he manages to win battles through luck and some talent.
- Level Grinding: The reason why he locks himself for training is to ensure that he will have higher stats than his opponents. At first, he uses the Fake Out skill to make his parameters lower than the real values, so that his opponents would underestimate him, when in reality, Seiya has the upper hand.
- Literally Shattered Lives: The toll for casting Valhalla's Gate Another is so severe that the wounds in his body begin to form cracks all over him, slowly killing him as his limbs disappear.
- Magic Knight: He can also learn various elemental spells, as well as channeling magic through his weapon.
- Major Injury Underreaction: Despite his dislike of taking even the slightest bit of damage, he has high pain tolerance. When Emperor Roseguard cuts his arm off, Seiya calmly activates a technique to mirror that damage onto the emperor's matching arm.
- Master Swordsman: After training with Cerceus and Adenela, he becomes skilled enough with a sword to adapt several of his techniques to Dual Wielding.
- Mook Horror Show: Seiya's enemies can grow quite terrified of him once he neutralizes any potential threats they possessed. Especially if he takes out a lot of them at once.
- Mr. Fanservice: The manga and anime trailer feature many shots of him working out while shirtless, and he's ripped in each one.
- Mundane Utility:
- Without their knowledge, Seiya gathers the hair strands of his companions (especially Rista) so that he could use them as synthesis material in forging new equipment with his Combine skill. Surprisingly, the results come with additional benefits depending on the person's hair. He speculates that the items will be of good quality when mixed with Rista's hair (one is a Platinum Sword), Mash's and Elulu's hairs helped forge the Dragon Killer sword since they belong to the dragonkin.
- Even though he isn't dealing damage at that point, Seiya kept on using "Gunshot Sword" against the Dragon Elder in order to push her off the ledge and make her die from falling.
- Seiya sees Mash and Elulu as his personal inventory carriers. After he defeats Beel Bub and the demon flies, he commands Elulu to buff Mash with Haste so that he can quickly carry the flies' corpses into a mound to be incinerated.
- My Greatest Failure: In his first summon, he rushed to save Ixphoria, which resulted him in being underleveled and lacking in information to finish Ixphoria's Demon Lord. He was too weak to stop the Demon Lord from eating his party in front of him before the Demon Lord ate his wife Tiana and their unborn baby. He deeply regrets this failure to the point where he becomes more cautious despite losing his memories.
- My Greatest Second Chance: Before getting killed by Ixphoria's Demon Lord, he left himself a message in his "Properties" window telling himself to be more cautious so he can save the next world to which he's summoned, along with any friends he makes there. He succeeds in saving the next world, Gaeabrande, though his real second chance arrives when he's resummoned to Ixphoria.
- Never Be Hurt Again: His subconscious only had his cautious personality left over after the mind wipe, meaning his constant pushing away people and extreme pragmatism is a result of not wanting to go through the same tragedy he experienced in Ixphoria.
- New Game+: The closest explanation for why Seiya has the "Overly Cautious" personality even at Level 1. He has already been summoned before in an attempt to save another world. He may have lost his memories of his past adventures, but the trait of being paranoid and cautious became ingrained in him due to the guilt of failing to save Ixphoria.
- Nice Job Breaking It, Hero!: Due to his overly cautious nature, Seiya made sure to pulverize Chaos Machina's remains to make sure that she won't regenerate. After casting Hell's Fire and Maximum Inferno repeatedly despite the others' protests, he accidentally sets Edona on fire, with the townspeople who previously praised him as a hero now demanding him to leave.
- The Nicknamer:
- Calls both Rista and Valkyrie "exhibitionists" after looking at their outfits. Both goddesses took offense to this.
- Calls Mash as "mushroom" or "organic mushroom".
- Calls Rista as "inferior herb woman" after her healing powers lost against a shopkeeper's herbal medicine.
- Not Quite Dead: After Seiya disappears into light from paying the toll of summoning two Valhalla's Gates, his friends mourned for him, thinking that he's truly dead. This wasn't the case as Ishtar revealed that the effects of Chain Destruction vanished as soon as Seiya summoned the second gate, and that his soul is perfectly safe, he's just sent back to Earth, and Rista can summon him again.
- O.O.C. Is Serious Business:
- After training with Valkyrie, Seiya doesn't state that he's "perfectly prepared." This is because he knows that his chances of beating Gaeabrande's Demon Lord are slim and that he plans on sacrificing himself to win. It also applies before he attempted to fight Eraser Kaiser. Fortunately, Wohlks was the one who killed Kaiser. Finally, in the next battle, Seiya never mentioned this when he figts Wohlks himself, and it shows that he had a hard time in their fight.
- Seiya shouting "Stop! You'll die!" with a worried expression and tone different from his usual stoic demeanor when his allies try to assist him in fighting Wohlks.
- At the end of Episode 10, Seiya tells the party that they should take some time for R&R, which is unusual for a training maniac like him. This is so he can leave to fight the Demon Lord by himself while everyone else is relaxing in the city.
- In Episode 12, after defeating the Demon Lord at the cost of his life, Seiya finally drops his cold front and thanks his party for their help.
- One-Man Army: He's so powerful that he can wipe out entire armies by himself. Early on in his adventure, he faces off against Deathmagla's 10,000 strong army of undead soldiers. He opts to throw a meteor that kills them all. And a second one, just to be safe.
- Out of Character: After Rista finds out that he faked the ultimate sword Igzasion, Seiya whispers "Gonna be okay" to himself in a worried tone.
- Overshadowed by Awesome: While Seiya normally battles the tougher opponents, after defeating Beel Bub, he tells Mash and Elulu it's their turn to shine and show off some of the new skills they got after training with Ariadoa. Thinking they'd finally get a chance to fight something,Seiya instead kills all the remaining flies by shooting at them very quickly with his bow. He then asks Elulu to use her Haste buff on Mash, and has Mash collect all the dead bodies so he can incinerate them all at once.
- Percussive Maintenance: Invoked. When he loses his memories during the Ixphoria arc, he hits his head against his jail bars, believing that he can fix himself like a broken TV. Fortunately, this method succeeds in restoring his memories.
- Playing with Fire: He specializes in fire elemental magic, though this means his aptitude for ice magic is low to compensate. He gets around this by making an accessory that allows him to use ice magic.
- Pragmatic Hero: When he learns that Chaos Machina set a time limit for him to return before she kills Nina's father, he insists on training until the last minute in order to maximize his chances of victory despite how heartless that seems. His reasoning is that if he fights her too soon, he'll lose and put Gaeabrande's entire population in jeopardy.
- Properly Paranoid: Despite the title claiming he's overly cautious, the demons are crafty and powerful enough to warrant his countermeasures. This is shown when the first demon general attacked him while he was traveling in a low-level plain, which would have resulted in his death if he didn't take several days to exercise in the gods' realm beforehand in the off-chance that he encounters a strong enemy in a weak area. When visiting the Dragons' Den, he correctly anticipates that he'll need to prepare to fight against its residents, and prepares an anti-dragon weapon that allows him to breach the Great Mother's defenses. His suspicion towards Emperor Roseguard is also warranted, and he correctly guesses that the emperor made a deal with the Demon Lord out of frustration towards his aging body.
- Real Men Hate Sugar: Going by his disgusted response both times people offered him cake, he doesn't care much for sweets.
- Screaming Warrior: When using Valhalla Thrust to push Gaeabrande's Demon Lord into Valhalla's Gate, Seiya screams at the top of his lungs.
- Shed Armor, Gain Speed: Before fighting Wohlks, Seiya gets serious by dropping all his accessories and arm braces on the floor in order to attack faster.
- Smug Super: Subverted. Due to his recklessness and devil-may-care attitude, Seiya's expression was mostly smug in the past. Then a tragedy happened during the final fight that changed his overall expression to The Stoic Seiya whom we knew from the start.
- Stereotype Flip: Rista expects most Japanese to be familiar with Isekai tropes due to the popularity of that genre in their country. To her surprise, Seiya isn't familiar with such tropes, as shown when he doesn't recognize a slime as the typical weak fantasy monster. Despite this, he's very creative about using his JRPG abilities.
- Stock Light-Novel Hero: A hilarious parody. Rista chooses to summon Seiya because he has some of the highest stats of any potential hero. Seiya is also a dark-haired, handsome hunk with a chiseled body and stoic persona. From the moment he appears, she lusts over him, and eventually, he gains the admiration of several other goddesses within the divine realm. However, he is The Paranoiac that won't do anything unless he is "perfectly prepared". He will spend weeks at a time doing nothing but training or working out until he has maxed out every single skill available, synthesizes the most powerful weapons as well as backups of those weapons and backups to the backups, buys hundreds of helpful items in bulk, and treats every single person he meets with complete suspicion and caution, including his own party members and Rista herself. And it's a good thing, because the villains of this world are just as savvy and prepared.
- Strong and Skilled: He's considered an exceptional hero due to his high stats and ability to learn new skills quickly. However, he's Weak, but Skilled compared to Gaeabrande's Demon Lord and Emperor Roseguard, since he cannot surpass their stats despite hitting the level cap, forcing him to rely on creative tactics to come out on top.
- Talented, but Trained: While Seiya is able to learn many skills by leveling up or seeing the skill used once, he trains under the gods so he can learn abilities he wouldn't normally have.
- There Is No Kill Like Overkill: He always blasts an enemy's corpse into oblivion with his fire magic and Atomic Split Slash, just in case they can come back From a Single Cell. Considering Ixphoria's Demon Lord defeated him by coming back to life from his upper body, Seiya has a point in doing this.
- A Tragedy of Impulsiveness: When Aria summoned him to Ixphoria, Seiya tried to defeat the demon army as quickly as possible so that the people of the world won't have to suffer longer than necessary. While he has noble intentions, his lack of preparation gets him and his party killed by Ixphoria's Demon Lord.
- Uniqueness Value: Seiya is viewed a rare hero, or a "one-in-ten-billion people" genius by Rista due to his overpowered stats even at Level 1.
- We Have Reserves: Defied. He refuses to bring Roseguard's troops with him to fight the undead army because he doesn't want them to risk their lives for nothing. He chews out Rosalie for sending her soldiers to their deaths in battles they have no hope of winning.
- Weapon of X-Slaying: He forged the Dragon Killer swords which help in slaying dragons. This is due to his suspicions of possibly having to defeat a dragon in their village. He's right, since the Great Mother of Dragons picked a fight with his party.
- When He Smiles: Before dying, he finally gives a heartfelt smile upon realizing that Rista is the reincarnation of his lover from a previous life and he got to see her one last time.
- Willfully Weak: One of, if not the first ability he learns is one that hides his true level and stats, which he keeps a secret even from Rista. It's only against Chaos Machina that he finally reveals his true strength.
- Wistful Amnesia: He doesn't remember his journey in Ixphoria, but he still feels subconscious regret over failing to save that world, which is why he became overly cautious.
- Would Hit a Girl:
- He throws Rista at a wall head-first hard enough for her to bounce to quickly get her off of him after landing on top of him due to their hasty retreat to the Divine Realm so he can immediately start working out some more, and conks her over the head when she's about to teleport him directly to Edona for his rematch with Chaos Machina, insisting on being teleported further out instead.
- He slaps Princess Rosalie when she insists on marching herself and her army into a hopeless battle with flying insectoid demons. He slaps her again when she refuses to reconcile with her father, who went through a Death Equals Redemption situation.

The Goddess of Sealing, who saved over three hundred worlds.
- The Ace: She's one of the most experienced goddesses, as shown by her track record of saving hundreds of worlds. Even Valkyrie, who looks down on most other deities, respects her. Her experience is shown when she advises Seiya to take advantage of the Divine Realm to train under other deities and when she figures out how to make Mash and Elulu stronger.
- Buxom Is Better: One of the first things we learn about her, courtesy of Rista bringing attention to it, is that she has G-cup sized breasts, which Rista expresses some envy towards.
- Cool Big Sis: She has this dynamic with Rista as she's very kind and protective of her.
- Eaten Alive: Her fate at the end of her failed quest to save Ixphoria, courtesy of the local Demon Lord.
- Foreshadowing: There are some suspicious stuff that hints Aria's connection to Seiya:
- Aria spills the tea she's holding, as if she is very surprised to see Seiya face-to-face again.
- She speaks in a very casual tone to Seiya and addresses him on a first-name basis when she interrupts the ruckus between him and Valkyrie. Of course, Seiya is curious and wary about this casualness since they haven't met yet. He's wrong though, as they have already met before.
- Rista wonders why Aria can be calm about any situation regarding Seiya and seemingly knows about him more when in fact, the former has been with him for longer. Aria panics briefly, stating that it's because Rista tells stories about him a lot. What Rista doesn't know is that Aria is the first goddess who summoned Seiya before she did.
- She seems too emotional whenever Rista talks about Seiya, as if she's trying to distance herself from him. A Wham Shot even shows Aria crying when she realized that Seiya went to face the Demon Lord of Gaeabrande by himself. This is due to regret, or a fear that Seiya might die again.
- Ignored Expert: She advised Seiya to visit a faraway village to gather information on Ixphoria's Demon Lord. In his haste, Seiya had the party go straight to the Demon Lord, resulting in their demise when they're unprepared for the enemy's self-revival skill.
- Mentor Archetype: She teaches Elulu some Status Buff abilities, and helps Mash in unlocking his dragon form.
- A Million Is a Statistic: Defied. Aria is ashamed of failing to save a single world, since that world is all the residents had, and now they're doomed to suffering under the rule of the Demon Lord.
- Mundane Utility: Her power over seals can be used to unlock doors.
- My Greatest Failure: Her failure to save the B-ranked world of Ixphoria weighs heavily on her. She tries to talk Ishtar into sending her back during Rista's sentencing in the latter's place, but is denied the opportunity.
- My Greatest Second Chance: Her efforts to assist Seiya and Rista can be seen as this, since Seiya was the hero she originally summoned to Ixphoria, while Rista is the reincarnation of one of her companions from that world.

The Great Goddess in charge of all the others.
- Big Good: She's the leader of the gods and gives them the information they need to save various worlds.
- Cool Old Lady: Her physical appearance looks a good deal more elderly than the other gods, and she's one of the kindest and wisest people amoung the whole cast.
- Ms. Exposition: Ishtar narrates Seiya's true personality to Rista, Mash and Elulu, that he doesn't want to see his allies die, and why he pushes people away so that they wouldn't join him in battle, she later reveals his backstory in Ixphoria via a flashback sequence.
- Not So Above It All: She openly suggests to Rista that the latter should take a bath, as she bluntly tells her that she smells like vinegar. This is right after Seiya mocked Rista's body odor.
- The Omniscient: She's aware of everything that occurs in every world, and is described as all-knowing.
- Reasonable Authority Figure: She's willing to push the limits of the gods' non-interference rules so that Rista and Seiya can save Gaeabrande. When Rista breaks the rules by using her full healing powers to help Seiya, Ishtar takes into consideration that she did succeed in her mission. Instead of taking away Rista's godhood, Ishtar orders her to save Ixphoria without using her healing powers, but also allows Seiya to be summoned again. Additionally, she wasn't the one who set the healing restriction on Rista, and later petitions the three highest ranking gods to lift that restriction, due to how Ixphoria's demons have Chain Destruction.
- Religious and Mythological Theme Naming: Her name is taken from the Babylonian Goddess of fertility.
- Sink-or-Swim Mentor: The first volume of the manga has an easily missed short story on the back cover explaining that Ishtar is the one who assigned Rista to Gaeabrande. Nominally, her reason is to motivate Rista, who became complacent after saving five worlds. While explaining her reasons, Ishtar glances over at a list of summonable heroes, implying that she chose Gaeabrande knowing that Rista would summon Seiya.
- Top God: Subverted. She's the leader of all the deities in the Divine Realm and is considered the highest ranking one, but Valkyrie is the strongest in terms of combat ability. Later, it turns out she ranks lower than Brahma, Nemesil, and Chronoa.

A god known as the Divine Blade.
- Break the Badass: Despite being a Master Swordsman, constantly training and losing against Seiya causes him to become traumatized to the point of hating swords.
- Chekhov's Gunman: Because of him, we learn that some gods were once humans that ascended and lost their memories of their mortal lives. This sets up The Reveal later on.
- Heroic Second Wind: Played with. He instantly regains his pre-Seiya personality after he scans Mash when being requested to be his instructor.
- Jerk with a Heart of Gold: Rista notes that it's scummy of him to only get his motivation back when the next person to be trained by him, Mash, is far weaker than him. That said, he's still willing to take the time to help the protagonists, even when it means training Seiya to surpass him again in the Ixphoria arc. He also gives Rista a cake to console her when she's grieving over Seiya's sacrifice.
- Master Swordsman: He's the god who's an expert in swordsmanship... That is, until Cerceus got traumatized after Seiya turned out to be stronger than him. And then, it turns out even Adenela is better than him.
- Mentor Archetype: Was one of Seiya's first mentors and sparring partner among the Gods and Goddesses. Cerceus later became the mentor to help Mash level up early on.
- Red Baron: The Divine Blade.
- Reincarnation: According to Ishtar, Cerceus was once a human who went through some kind of trauma, which explains why he lost his confidence after training Seiya.
- Supreme Chef: Following his experiences with Seiya, he decided to take up baking as a hobby in order to be as far from swords as possible. Going by the cake we see, he actually got pretty good, even if none of Seiya's party wanted it.
- Training from Hell: His training was supposed to be this for Seiya, but the latter insisted on continuing the training despite surpassing his teacher, turning the hell back on Cerceus.
- Worf Had the Flu: Deities aren't allowed to use their full power against humans, even when training. As a result, Seiya surpasses him in a matter of days.

The Goddess of Fire.
- Fiery Redhead: Elulu suspects Hestiaca is an example, due to the latter's red hair and association with fire. This turns out to be averted, since she's a calm and friendly goddess.
- Flat Character: She's only introduced to try and help Elulu with fire magic. As such, Hestiaca has a minimal amount of screentime compared to the other named deities since she doesn't personally train Seiya in any way, and her training with Elulu is short-lived.
- Mentor Archetype: She tries to teach Elulu fire magic, but this doesn't last long because it turns out Elulu doesn't have much aptitude for this type of magic.
- Religious and Mythological Theme Naming: She's named after Hestia, the Greek Goddess of the Hearth.

The Goddess of Destruction.
- Ambiguously Bi: She shows an interest in grabbing the breasts of other goddesses, but she is also found naked in bed with Seiya stating how much of a man he is.
- Cast from Lifespan: Valhalla's Gate is cast in exchange of one's own life. The user could survive if they have maxed out stats, though.
- Chained by Fashion: As opposed to the gowns that the other goddesses wear, Valkyrie wears chains in a way similar to a sarashi.
- Combat Sadomasochist: When the backlash of Valhalla's Gate leaves her in a puddle of her own blood, she enjoys the pain.
- Dangerous Forbidden Technique: Valhalla's Gate traps an enemy in a gate that is supposed to completely destroy them. The backlash is so great that she needs to have maxed out stats in order to survive. It's possible to summon another gate in case the enemy survives the first one, but the user will be shattered to the point where Rista's healing magic isn't enough to save them.
- Destroyer Deity: Her title.
- Everyone Has Standards: She's disturbed when Rista shows that she made a doll of her own hair for Seiya. However, Valkyrie doesn't know that Seiya is able to use Rista's hair as synthesis ingredients.
- Face Palm Of Doom: Her Shattered Break skill involves crushing her opponent's head. It doesn't work on Crossed Thanatos.
- Godzilla Threshold: Crossed Thanatos is such a rare threat due to being a Nigh Invulnerable foe, that Valkyrie requests Ishtar to max her stats just so that she can use Valhalla's Gate.
- Hidden Depths: It turns out she enjoys drawing, and at one point, is seen making an oil painting of the Divine Realm.
- Iron Maiden: Her Valhalla's Gate skill is basically this. It's a creepy, towering mechanical torture device that can trap the target inside.
- Jerk with a Heart of Gold: She's normally a prime example of a Jerkass God, since she often threatens deities and heroes that annoy her and has a habit of groping her female colleagues. However, Valkyrie does gain enough respect for Seiya to teach him Valhalla's Gate and is touched by his determination to save Gaeabrande. She also tells Rista that she'd like to paint her picture someday after Gaeabrande's Demon Lord is defeated.
- Mentor Archetype: She teaches Seiya Valhalla's Gate.
- Religious and Mythological Theme Naming: Her name, and the name of her iconic skill, Valhalla's Gate, are based from Norse mythology terms.
- Required Secondary Powers: Valhalla's Gate takes a major physical toll on the user, which is why she requests a buff from Ishtar that maxes all her stats to 9999999 and her HP at 99999999, allowing her to survive the backlash.
- Stripperiffic: Her outfit exposes a lot of skin, which is one of the reasons why Seiya calls her an "exhibitionist".
- Summon Bigger Fish: Seiya utilizes this after he, along with many other gods and goddesses, are unable to defeat Crossed Thanatos, who followed them into the Divine Realm. He gets Valkyrie involved not by asking nicely, since he figured she wouldn't, but by dodging an attack by Crossed Thanatos, which hits and destroys the painting Valkyrie was working on at the moment. Despite this, even Valkyrie is forced to use a Dangerous Forbidden Technique which also deals massive damage to herself and would've been fatal had a human of used it.
- Terrible Artist: She's not very good at drawing despite her interest in it. We see a painting of Aria in her room in Episode 9... at least, what appears to be Aria.
- Too Kinky to Torture: After utilizing her Limit Break attack that was also Cast from Lifespan to defeat Crossed Thanatos, Valkyrie starts spurting blood all over her body. Rista is more creeped out that Valkyrie mentioned she could get used to this pain, than the fact that she was spraying blood all over the place.
- World's Strongest Man: She's the strongest deity in terms of combat.

The Goddess of War.
- Affectionate Gesture to the Head: Headpats are all it takes for Seiya to calm Adenela back when she was just going berserk earlier.
- Battle Aura: Her body can be engulfed with a dark-red burning aura when she was about to kill Seiya for rejecting her.
- Big Damn Heroes: She saves Seiya and Rista when they're about to be killed by a werewolf that invaded the Divine Realm.
- Contralto of Danger: Her voice is normally quite deep and breathy, but it'll switch to a squeaky high once she's in lovey-dovey mode.
- Creepy Basement: Her room is themed after one; it's dimly lit by a skull-shaped lamp giving off a sallow green light.
- Creepy Good: Messy hair, lives in the dark, creepy smile and keeps laughing at random times, but she is still a heroic goddess.
- Creepy Shadowed Undereyes: Her eyelids have a darker pigmentation underneath.
- Crush Blush: Evident after her first training session with Seiya, everytime she or others mention his name.
- Expressive Hair: The curls in her hair twist into hearts when she forgives Seiya, and do so again to a lesser extent when she sees Seiya again when he's running away from Crossed Thanatos.
- Flash Step: She can move short distances in the blink of an eye, as demonstrated when the protagonists first met her. Only Seiya is able to track her movements.
- The Glomp: Throws herself to Seiya and hugs him just before his group is about to leave.
- Laughing Mad: She tends to randomly giggle while speaking. She drops it in lovey-dovey mode though.
- Legacy Character: During the Ixphoria arc, it's revealed that she's actually the second Goddess of War. The previous goddess, Zeth, was imprisoned within a well after she attempted to rebel against the Divine Realm.
- Looks Like Cesare: Much more attractive than the usual example, but otherwise hits all the hallmarks.
- Love at First Sight: Downplayed. Adenela didn't have strong feelings for Seiya when they first met, but she did fall for him right after their first training session, complete with Adenela finally learning how to groom herself in three days just to impress Seiya.
- Master Swordswoman: She's better at swordplay and martial arts in general than Cerceus, to the point of knowing a sword skill that unleashes near-simultaneous slashes in multiple directions.
- Mentor Archetype: She's one of the deities whom Seiya trained with in order to learn a new ability.
- Messy Hair: Typically, her hair is matted and disheveled, with two strands even resembling horns, but she fixes it up (along with the rest of her appearance) after gaining feelings for Seiya.
- Nightmare Face: Likes to pull these off in her Woman Scorned mode. Variants include the Ghostly Gape, Glowing Eyes of Doom, and the Slasher Smile.
- Pet the Dog: She tries to console Rista after Seiya sacrifices himself to kill Gaeabrande's Demon Lord.
- Room Full of Crazy: Her room is filled with the word "kill" after Seiya rejected her and her cake.
- She Cleans Up Nicely: She normally looks unkempt until she decides to straighten her hair and wear proper clothes to look good in front of Seiya. It doesn't last long, though.
- Simultaneous Blade Spam: Her signature Eternal Sword technique, which requires abnormal limb rotation beyond a normal human's ability.
- Sugar-and-Ice Personality: She's a dark, isolated and gloomy girl, but is actually rather nice once you get to know her. In fact, after she falls head over heels for Seiya, she briefly drops the dark and gloomy look to appear more attractive to him.
- Woman Scorned: Subverted. When Seiya rejects her, she vents her anger on a nearby statue. The next time they meet, she's about to attack him with her sword, but he caresses her hair, causing her to instantly forgive him. Aria also claims that Adenela doesn't really have it in her to kill Seiya.
- The Worf Effect: She's unable to damage Crossed Thanatos, who is immune to most attacks.

The Goddess of the Bow.
- Adaptational Villainy: In the web novel, she was exiled for "sexually eating" one of the heroes she summoned. In the Yen Press light novel translation, she kidnapped and raped multiple heroes.
- Black Comedy Rape: Attempts this with both Seiya and Mash.
- Brick Joke: She moves on all fours and crawls like a spider just as she reveals her horny side in the forest. By the end of the Gaeabrande arc, Mitis sneaked to the central area of the Divine Realm, but once Aria ordered her to go back to the forest, she crawls like a spider again on the way out.
- Dirty Old Woman: A nymphomaniac goddess who has a fetish for mortals who naturally she's hundreds of years older than at least. When she can't get her hands on Seiya, she then targets Mash saying that she's "perfectly fine with a shota."
- Double Entendre: Sexual innuendos go along with her perverted and masochistic trait:Mitis: I'm being pierced by something thick and long!Elulu: What is Mitis-sama saying!?
- Erotic Eating: After she witnessed Seiya calming down an enraged Adenela, Mitis sensually licks an apple before biting it.
- Foil: To Adenela:
- Adenela likes to dress messily with dark clothes, and her hair is a messy purple. Mitis is immaculately dressed in a white dress with straight white hair.
- Adenela is a Master Swordswoman, Mitis is a master of the bow.
- Adenela appears creepy and unhinged, but is actually quite nice. Mitis appears prim and proper, but is actually an unhinged nymphomaniac.
- Both Adenela and Mitis gain feelings towards Seiya. Adenela harbors love, albeit unrealistic and despite being rejected, can't bring herself to harm him. Mitis only feels lust and has no problem raping him for her own pleasure.
- Improbable Aiming Skills: She shoots all three of Seiya's firebirds with one arrow.
- Interplay of Sex and Violence: She orgasms when Seiya manages to pin her to a tree with five consecutive arrows. Rista had to quickly transport Mash and Elulu to Gaeabrande to prevent them from seeing.
- Lovable Sex Maniac: Averted due to the consequences. Aria states that she's a horny goddess who sexually "ate" a hero she summoned. Since relationships between deities and humans are forbidden, Ishtar exiled her to a forest in the Divine Realm. Aria implies the humans in the relationships would be punished too, which is bad for the imperiled worlds if their heroes are involved in these relationships.
- Mentor Archetype: She teaches Seiya some archery abilities.
- Nightmare Face: In the anime, she gains red sclera and pointy teeth when she reveals her true horny colors.
- Token Evil Teammate: She's one of the deities who mentors Seiya, but she turns out not to be as benevolent as she first appears. Despite being exiled for starting a relationship with a hero, she never learned her lesson at all, and planned to rape Seiya (and later Mash) at the end of their training. Fortunately, Seiya prevents this with his newfound archery skills, but this event does show why even the kind and understanding Aria considers Mitis to be a terrible goddess. The token part is subverted when the Ixphoria arc introduces a second Goddess of War, Zeth, who was exiled into a well for rebelling against the other gods.

A young dragonkin warrior, who becomes one of Seiya's inventory carriers.
- Break the Badass: Combined with Break the Haughty due to his initial overconfidence in trying to fight Deathmagla. After being tortured by Deathmagla, Mash is traumatized to the point where he can't fight. Fortunately, witnessing Seiya defeat Deathmagla reignites his fighting spirit.
- Defiant to the End: When Deathmagla cuts the cloth binding Mash's mouth shut, he expected Mash to beg for his life. Instead Mash realizes just how insanely powerful Seiya was, and encourages him to save the world in his place. Deathmagla isn't too pleased about that, though he doesn't get much time to actually kill Mash as Seiya immediately jumps into action to save him.
- Face Death with Dignity: When Deathmagla captures him and is about to kill him, Mash asks Seiya to save the world in his place. Fortunately, Seiya turns out to have a skill that can cut through the fabric of space, allowing him to save Mash despite being in a different location.
- Hero-Worshipper: He's initially hostile to Seiya due to the latter rejecting the dragonkin duo as companions. After Seiya saves him and invites him to carry his bags, Mash does a 180 and becomes one of Seiya's most loyal followers. He also adopts Seiya's cautious methodology in order to emulate him.
- Human Pack Mule: He and Elulu spend most of the journey carrying Seiya's inventory.
- Imagine Spot: Mash has some lewd visual thoughts when a naked Mitis is about to pounce on him.
- Mundane Utility: He gains the ability to transform into a Dragonewt and later into a huge dragon. Seiya remarks that this means he can carry more stuff.
- Overshadowed by Awesome: Despite his power ups throughout the journey, he's still far weaker than the higher tier threats in the demon army. Though his stats are surprisingly high for his level, as shown by how his level 21 stats are about a third of Seiya's level 99 stats and mostly surpasses Seiya's level 51 stats, which suggests Mash could become stronger than Seiya with enough leveling.
- Passing the Torch: Seiya's last words to him is telling him that with the Demon Lord and Four Heavenly Kings dead, Mash is now the strongest being on Gaeabrande thus it's his responsibility to protect it. In Mash's last meeting with Rista, he makes it clear he plans on protecting the world that Seiya saved.
- Took a Level in Badass: After training with Cerseus and unlocking his dragon form, he ends up becoming one of the strongest beings in Gaeabrande.
- Weredragon: Thanks to his dragonkin nature, Mash can transform into a dragonewt and later got upgraded into a dragon form.
- World's Strongest Man: At the end of the Gaeabrande arc with the Demon Lord, the four Heavenly Kings and Seiya all dead, Mash is the strongest being on Gaeabrande.

A young dragonkin mage, who also becomes one of Seiya's inventory carriers.
- Heroic BSoD: Played for Laughs when she briefly becomes depressed after Seiya quickly learned the fire bow skill that Elulu thought was difficult and complex. She spends the next few scenes wanting to do nothing else but eat sweets.
- Hesitant Sacrifice: The Dragon Mother intended for her to be sacrificed to create the sword, Igzasion. Elulu goes along with it, but admits she still wants to live and continue traveling with the party. Fortunately, Seiya prevents her sacrifice, though he makes sure not to tell her or Mash that he failed to obtain the sword, otherwise they'd feel guilty.
- Human Pack Mule: She and Mash spend most of the journey carrying Seiya's inventory.
- The Load: She initially thinks of herself as useless because she couldn't improve in fire magic, but this is subverted when she learns how to cast support magic, which Seiya notes allowed him to barely win against Emperor Roseguard.
- Nice Girl: She's the most kindhearted member of the Gaeabrande party. Even when she's upset that Seiya rejected her and Mash, she doesn't direct hostility towards him like Mash.
- Playing with Fire: She originally tried mastering fire magic, but Hestiaca reveals she didn't have much talent for it.
- Support Party Member: She turns out to be talented in auxiliary magic, and can cast spells to slow or hasten targets.
Great Mother of Dragons
Voiced by: Masako Katsuki (Japanese)
The leader of the dragonewts.
- Crazy-Prepared: She already expected the party to oppose Elulu's sacrifice, so she had her citizens lace the party's food with paralytics and gave Elulu a Death Sentence Necklace that kills her within a time limit. Seiya states she wasn't cautious enough and that she should have activated her Ultimate Wall during the banquet to prevent any opportunity for Seiya to damage her wings.
- Death by Irony: She dies the same way she intended to kill Elulu: falling into the pit and getting turned into a sword.
- Disney Villain Death: Seiya defeats her by making her fall into the same abyss she was going to use to sacrifice Elulu. He also damaged her wings before that to ensure she can't fly out.
- Foil: She shares Seiya's belief that being cautious is necessary to save the world. Unlike Seiya, who is willing to compromise on caution in order to save his friends, she's willing to sacrifice an innocent girl to ensure victory.
- Motive Decay: Despite wanting to create Igzasion for Seiya to use, she becomes so enraged at his opposition to her plans that she tries to kill him with her fire breath attack, despite how doing so would leave no one capable of using Igzasion to kill the Demon Lord.
- Named by the Adaptation: The anime names her Leviae, despite how the web and light novels don't give her a name even in her status window.
- One-Winged Angel: She normally appears as a normal-sized dragonewt, but can transform into a massive dragon.
- Redemption Rejection: Seiya offers her to surrender because she's not part of the demon army, but she refuses and continues with her plan to sacrifice Elulu.
- Ring-Out Boss: How she meets her end. She's invincible while using Ultimate Wall, but not unmovable. This proves to be fatal as Seiya is pushing her towards pit that will kill her should she fall in.
- Slipping a Mickey: She throws a great feast for the heroes while preparing Elulu for her planned sacrifice, with some children handing them cookies they baked. Later when they start having doubts about wanting to lose Elulu, both Mash and Ristarte fall to the ground, unable to move due to their tampered drink and cookies from earlier. Seiya is unaffected because he never drank any of that same drink, and reveals that he threw up the cookies shortly after eating them.
- Stone Wall: Her strategy is to tank Seiya's attacks using her damage resistance passives and Ultimate Wall skill until Elulu dies from the Death Sentence Necklace, since she's no match for him in offense or speed. Her resilience is made more impressive by the revelation that Seiya is already at the level cap. Lampshaded by Seiya, who compares her to a Nurikabe, a wall-like yōkai.
- Villain Has a Point: Her insistence on creating Igzasion makes sense when the Demon Lord turns out to be able to tank all of Seiya's weapons other than Valhalla Blade.
- Well-Intentioned Extremist: Her status screen describes her as self-righteous and she'll do anything to ensure the fall of the Demon Lord. Her plan is for Elulu to absorb energy from the human world and eventually sacrifice her to make Igzasion. She also executed Elulu and Mash's families for opposing this plan.

The dragonewt guarding the entrance to the Dragon Village.
- Nice Guy: Despite Seiya making him teleport a small lizard out of paranoia, Lagos takes it well and compliments the hero for his caution. He's also thankful that the party saved Elulu from being sacrificed and he only warns the party to leave because many other dragonewts are angry at Seiya for killing their leader.
- Token Good Teammate: He's one of the few dragonewts who disagreed with sacrificing Elulu, though he couldn't voice his opinion because the others would execute him for it.
Princess Rosalie Roseguard
Voiced by: Yumiri Hanamori (Japanese), Madeleine Morris (English)
A princess of the empire who is in charge of Olga Fortress.
- Alliterative Name: Rosalie Roseguard.
- Armor-Piercing Slap: What she tries to do Seiya after insulting her. Instead, he blocks her and slaps her right back. And she tries to do this several times until her face is swollen.
- Break the Haughty: She gets slapped by Seiya, nearly killed by Beel Bub, and witnesses her father falling to villainy. By the end of the Gaeabrande arc, she's become much more levelheaded.
- Brick Joke: Every time Seiya calls Rosalie a dog, her mouth does turn like a dog's soon after, including the fangs! The name-calling happens twice, first after slapping some sense into her, and after he rescued her from Beel Bub. After Eraser Kaiser is defeated, he does subtly piss off Rosalie without calling her a dog, but she's still drawn with fangs when angered.
- Complaining About Rescues They Don't Like: After Seiya saves her from Beel Bub, she calls him a coward for using sniping and trickery to win rather than direct combat.
- Cry Cute: She cries as her face gets swollen from Seiya's repeated slapping.
- Due to the Dead: She is first introduced praying in the Field of Blades where her comrades recently died.
- Foil: Seiya's cautiousness is in contrast to Rosalie's recklessness.
- General Failure: Seiya lays the blame of her soldiers' death at her feet, claiming it was her recklessness that killed them all.
- Hero-Worshipper: She idolizes her father as the strongest man in Gaeabrande and the paragon of heroism and chivalry.
- Honor Before Reason: She believes a true hero will play fair and and straightfoward, causing her to rush in recklessly. Too bad literally no one else in Gaeabrande thinks the same way she does.
- Jerkass Has a Point: Combined with Hypocrite Has a Point. She claims that the gods, who live safely due to their immortality and godly realm, wouldn't be able to fully comprehend the perils that mortals face. There is some truth to her words, since the gods prioritize following their rules despite that getting in the way of saving the world. Rista also didn't fully understand the weight of saving the world at the beginning of the story. Seiya admits she has a point, but tells her that she doesn't have much room to talk about respecting life after she recklessly marched her troops into battle with the insect army, causing many to be needlessly killed.
- Leeroy Jenkins: Her strategy to defeat Beel Bub's insect army is to invade their hive, despite their overwhelming speed and aerial advantage against humans. Seiya points out that this approach is the reason why so many of her forces were already killed by the insects.
- Luckily, My Shield Will Protect Me: Rosalie has a Light Protection skill that grants a barrier around her to protect while she's climbing up the demon flies' nest. It's not of any use against Beel Bub.
- Not So Different: When the party sees a vision of Seiya's past, they muse that he used to be just as reckless as Rosalie. This may explain why Seiya chafes with her more than his other detractors.
- Overshadowed by Awesome: Her stats are numerically superior to Chaos Machina's true form's, which is pretty impressive for a mere human at level 23 and suggests she will match her father and Seiya once she's gotten stronger. Unfortunately, they're all four digits at the point in the story when everyone is boasting stats of five or six digits.
- Parting Words Regret: Defied by Seiya, who convinces her to talk to her father as he dies.
- Pretty Princess Powerhouse: A princess who fights on the front lines against the demons. Unfortunately, this is the one time when it's probably better the princess doesn't take command thanks to her lack of strategic skills.
- Royals Who Actually Do Something: She is the princess of her nation and leads an army against the demon forces.
- Took a Level in Kindness: After Seiya gets her to reconcile with her father, she becomes more appreciative of him.
- You Gotta Have Blue Hair: She has blue hair.
Emperor Wohlks Roseguard
Voiced by: Tetsuo Kaneo (Japanese), Juri Kimura (Japanese, child), Yuuki Ono (Japanese, demonkin)
The emperor of Roseguard, and Rosalie's father.
- Adaptational Badass: In the web and light novels, he fought defensively against Eraser Kaiser in order to learn and counter the latter's fighting style. In the anime, he kills Kaiser immediately.
- Adaptive Ability: The longer he fights against an enemy, the more his stats increase due to his passive skill, Evolve Attack. It's unknown if these stat increases are permanent.
- Always Someone Better: He discovered the Demon Lord was much stronger than him, and came to worship him because of it.
- Authority Equals Asskicking: He is the emperor of Roseguard as well as its best warrior.
- Bare-Handed Blade Block: Wohlks tries this to protect himself against Seiya's Phoenix Thrust, it failed miserably.
- Broken Pedestal: Rosalie is angry to learn of his betrayal, and almost refuses to console him as he dies until Seiya slaps her again.
- Catchphrase: "Accustomed. I've already adapted to this too." Used in combat after he's finished analyzing an opponent's technique and is about to turn the tables.
- Climax Boss: He's fought right before The Reveal, and he's the first opponent Seiya couldn't beat in a straight fight.
- Deal with the Devil: He became depressed over his aging body, leading him to sell out to the Demon Lord in exchange for demonic powers.
- Death Equals Redemption: As he dies, he apologizes to Rosalie and pats her on the head, telling her that he loves her.
- The Dragon: He's the Demon King's last ally after Eraser Kaiser's death, and he's the one given the duty of killing Rista and Seiya permanantly with the God Eater.
- Fallen Hero: He's Gaeabrande's top native warrior and the ruler of the Roseguard Empire, one of the main lines of defense against the Demon Lord. Which makes it all the more shocking that he joined the demons.
- Feeling Their Age: As an 80-year-old man, he's not as strong as he used to be, something he's frustrated about. It's part of the reason he sold out to the Demon Lord.
- Famous Last Words: "Rosalie... I love you."
- Green-Eyed Monster: Besides his grief over his aging body, his second reason for joining the Demon Lord is because he's jealous that Seiya gets to be the hero who fights the Demon Lord while he's relegated to support at best.
- Knight of Cerebus: Once he is revealed as a villain. His fight with Seiya is played completely seriously. Right after he appears, we get The Reveal about Seiya's past.
- Light 'em Up: Uses primarly light based attacks. He switches to Casting a Shadow versions after he turns into a demon.
- Long-Haired Pretty Boy: What he looks like after taking a substance that turned him into a demonkin, something that resembles an adult man in his prime.
- Major Injury Underreaction: After he and Seiya take off each others' arms, he's more worried about losing his sword than bleeding out.
- Master Swordsman: During his battle with Seiya, he overwhelms the latter in swordplay and only loses because Seiya reflected damage onto his arm via a destruction technique. Notably, Seiya is already buffed to be much faster than Wohlks, had taken off his training weights to double his speed on top of that, and was taught swordplay by the gods, but still lost in a straight fight.
- Power-Up Food: A substance given by the Demon Lord allowed Wohlks to turn into a demonkin, boosting his stats, while giving him the physique of an adult man.
- Red Eyes, Take Warning: His eye color changes from blue to red after he becomes a demon.
- Underestimating Badassery: He thinks Seiya, being from a more peaceful world, has lower pain tolerance and would fold as soon as he receives a major injury. He's proven wrong when Seiya continues fighting despite losing an arm.
- Villainous Valor: Even after becoming a demon, his status still lists his personality as "valiant," which is shown by how he doesn't falter in his battle with Seiya despite losing his arm and his weapon.
- Weapon of X-Slaying: He wields the God Eater, a weapon based on the Demon Lord's Chain Destruction, which can permanently kill deities and heroes. He uses this when he reveals his true colors to the protagonists and Rosalie, threatening to kill them.
- World's Best Warrior: He's the greatest human warrior on Gaeabrande, as shown by how he easily defeated Eraser Kaiser, a demon general. After becoming a demon, he's stronger and more skilled than even Seiya.
Voiced by: Keiji Fujiwara (Japanese)
The leader of the demon army, who is said to be invincible if not faced with Igzasion.
- Anti-Magic: He established an anti-magic field around his castle to prevent the hero from simply nuking him with a powerful spell. This doesn't negate Valhalla's Gate, since that skill isn't considered magic.
- Arc Villain: He's the one responsible for the demon attacks in Gaeabrande, but he isn't the Big Bad of the overall series because he's only active in one world.
- Authority Equals Asskicking: Is the leader of the demon army and the strongest entity on Gaeabrande. Even outside of his One-Winged Angel form, he's immune to every attack by Seiya except for Valhalla's Gate, and even then he nearly breaks out of it forcing Seiya to use a second one on him.
- Dem Bones: Even when reduced to a skeleton, he's still able to move.
- Determinator: He succeeds in escaping one Valhalla's Gate despite being reduced to a skeleton and being hit in the face by Valhalla Blade. Fortunately, he ends up too weakened to survive another gate.
- Early-Bird Cameo: His silhoutte can be seen at the end of episode 6 alongside Eraser Kaiser after they finished constructing Chain Destruction.
- Generic Doomsday Villain: His motivations and backstory are never explained and he receives even less characterization than all his minions.
- Genre Savvy: He uses Chain Destruction in an attempt to kill the real souls of any hero or god who opposes him, preventing them from ever returning to impede him and acting as a deterrent against further divine interference.
- Hero Killer: Is said to be invincible and can only be harmed by the sword Igzasion. After Seiya's fight with Emperor Rosegaurd, it is made very clear he has little chance of beating the Demon Lord. Even with Rista's help, Seiya dies in the fight.
- Holy Burns Evil: Igzasion is able to harm him because of the immense sacred energy inside it.
- Maou the Demon King: A very generic example to boot.
- Multi-Armed and Dangerous: Like Eraser Kaiser, he has multiple arms, allowing him to hold open the doors of Valhalla's Gate while fighting against Seiya at the same time.
- Nigh-Invulnerability: Only the holy sword Igzasion can harm him as seen in his final fight with Seiya. The blades of Valhalla's Gate are the only other thing able to harm him.
- No Name Given: Unlike the Demon Lord of Ixphoria, Artemaeus, his name is never revealed.
- No One Could Survive That!: Despite Valhalla's Gate being touted as a skill that can destroy anything, including beings who can defy the laws of reality, the Demon Lord manages to barely escape one gate.
- One-Winged Angel: He can transform from his humanoid form to his true form as a multi-armed demon.
- Poor Communication Kills: He failed to tell Eraser Kaiser that Emperor Roseguard had secretly defected to their side. Wohlks kills Eraser Kaiser to keep up the deception until he could kill Seiya and Rista with a surprise attack.
- Taking You with Me: He has the ability to destroy the entire world with his Judgement Zero skill, and only uses it when Seiya reduces him to a skeleton. Rista states the skill has enough energy to destroy the world twice.
- We Hardly Knew Ye: Despite the build up and hype he receives throughout the story, he makes his proper appearance only at the end of a fight between him and Seiya right before he dies. We don't even get to see his stat sheet like most of the other villains!

The first and weakest of the demon generals.
- Ax-Crazy: When she speaks, she often repeats her words with a Slasher Smile on her face. Later, she takes joy in killing a random villager and gushes over their blood.
- BFS: Her weapon is a very large sword.
- Body Horror: After stabbing herself with her own sword, hands burst out of the wound, before the rest of her body becomes a massive winged bull-like demon.
- Boobs of Steel: Subverted. While she is pretty powerful, she's actually the weakest of the Demon Generals.
- Does Not Like Shoes: Due to having goat hooves, she doesn't wear shoes.
- Genre Savvy: Realizes that keeping tabs on a low-level area would allow her to kill any would-be heroes before they can pose a threat. Only Seiya's Crazy Preparedness saves him in the end.
- Growing Muscles Sequence: Her Release form has her bulking up a considerable amount.
- Hostage Situation: When Seiya and Rista flee to the Divine Realm, she takes the residents of Edona hostage and threatens to kill one every ten minutes if they don't come back.
- Impossible Hourglass Figure: Her first form is incredibly curvaceous, with large breasts and a small waist with wide hips and thick thighs, and it is even exaggerated with her Release form.
- Jump Scare: She causes one for Rista, who when using a crystal ball, is momentarily under the impression that she's aware. It also doesn't help that it's a bit too much of a close-up.
- Kick the Dog: She shortens the time for Seiya and Rista to return before she kills the next hostage, and nearly kills a man in front of his daughter.
- Knight of Cerebus: The story starts out lighthearted and treats Seiya's cautiousness as a gag. However, the situation becomes dire when she arrives, as not only is she a credible threat to the hero, she's also an example of how ruthless and sadistic the demons can be, as shown by how she takes Edona hostage. Despite Seiya curbstomping her in the end, her actions establish that the mission to save Gaeabrande is not to be taken lightly, and she sets the pace for the other demon generals' vileness.
- One-Winged Angel: When Seiya proves to be a match for her normal and Release forms, she transforms into a gigantic bullish demon with more than three times her original stats. Fortunately, it turns out Seiya was hiding his true strength too.
- Starter Villain: She's the first general encountered by Seiya and has the lowest stats, even in her bull form.
- Stripperiffic: Her outfit leaves very little to the imagination.
- Underestimating Badassery: She thought that she was still way above Seiya's stats when he returned. What she didn't realize was that Seiya faked his own stats, which prompts her to transform into her bull form. But even then, Seiya still had some tricks up his sleeve, such as Phoenix Drive, an advanced skill that one would not expect at his current level.
- Warm-Up Boss: She serves as this. Notably, she's the only enemy in Gaeabrande that Seiya beats just by using more raw power rather than a specific tactic.

A demon general who specializes in creating and controlling monsters.
- Armchair Military: He prefers to let his army of monsters fight on his behalf.
- Crazy-Prepared: He analyzed how Seiya was able to defeat Chaos Machina, so he makes Dark Firus immune to fire, which is Seiya's magic specialty. Unfortunately for him, Seiya has bracelets that can convert his fire magic into another element.
- Explain, Explain... Oh, Crap!: He learns the hard way that he shouldn't have revealed how to exploit the weakness of Dark Firus after Seiya does just that by taking advantage of the information in order to defeat the summon.
- Extra Eyes: He has a third eye on his forehead.
- Kick the Dog: He tortures and attempts to kill Mash in order to get back at Seiya, who destroyed his undead army. There was no practical reason to do so, as he simply wanted Seiya to be racked with guilt.
- Killed Offscreen: After Dark Firus is destroyed, he's last seen cowering before Seiya as Rista takes Mash away, before a Smash Cut to outside his castle, where his screams startle the birds.
- Mad Scientist: His forte is creating and upgrading all kinds of monsters to be much stronger than they normally are.
- No-Sell: He summons Dark Firus, a fire monster designed specifically to nullify physical attacks, as well as all the elements Seiya can use. It can only be damaged by using Oscillatory Wave, a pugilist skill, to upset its molecular structure before hitting it with ice magic. Fortunately, Deathmagla gloats about all these weaknesses believing Seiya won't be able to use the necessary skills, only to be proven wrong.
- Stupid Evil: He sends a magic mirror to Seiya so that the latter can watch him kill Mash. He doesn't realize doing so allows a very pissed off Seiya to track him down and cut him with a very long-ranged skill. He also commits the classic error of Explaining Your Powers to the Enemy.

A high-ranking insect demon who specializes in speed and aerial combat.
- Almighty Janitor: He's not one of the four generals, but he's still a deadly enough opponent that Seiya had to go back to the Divine Realm to train.
- Ax-Crazy: He and his minions' favorite tactic is to grab humans, fly to deadly heights, and drop them on the ground while bragging about the ensuing gore.
- Bring It: He tells Seiya to take his shot at him, and he won't bother moving until after Seiya has fired all his arrows at him. He more than proves his boast by dodging seven conescutive arrows effortlessly.
- Deadly Euphemism: His "reverse fireworks". Where he and his minions grab people, flies them as high as possible, and then drop them so they splat on the ground.
- Didn't See That Coming: He correctly analyzes where and how Seiya is going to attack him and dodges with ease. The one thing he didn't expect was Seiya's arrows turning around mid-flight when he wasn't paying attention.
- Flash Step: He can dodge arrows at fast speeds to the point where he looks like he's teleporting.
- Fragile Speedster: His agility stat is 487562, allowing him to dodge Seiya's arrows easily. However, his HP is only 18963 and his other stats are in the quadruple digits despite being at level 76, meaning he dies easily if he's actually hit.
- Home Field Advantage: He's unbeatable in the air thanks to his incredible speed. It doesn't even matter that the rest of his stats are crap, since his speed more than compensates for everything.
- I Know You Know I Know: Beel Bub can analyze on the spot the different possibilities on how a hero can counter him in mid-air. While holding her hostage, Rosalie accidentally reveals that Seiya trained to counter him. He then guesses that Seiya will snipe him from a distance, so Beel Bub flies up above the skies with Rosalie before attempting to drop her.
- In the Back: He thinks he can easily kill Seiya in aerial combat due to his speed. While he manages to dodge a volley of arrows from Seiya, he didn't expect the arrows to return and attack him from behind.
- Religious and Mythological Theme Naming: His name sounds similar to Beelzebub, a demon who is also heavily associated with flies.
- Unhand Them, Villain!: When Rista demands that he lets Rosalie go, he agrees by attempting to throw her towards the ground at a speed such that Rista can't catch her. Fortunately, Seiya shoots his arm off before he can do so.

The third general Seiya encounters.
- Bait-and-Switch Boss: The bait to Crossed Thanatos's boss.
- Beneath Suspicion: He's the dwarf shopkeeper of Izale Village, and flies under the party's radar the first time they meet him because he lacks any distinguishing features.
- Chekhov's Gunman: He is first seen as the shopkeeper in Izale Village whom Seiya's party brought torches from.
- Crazy-Prepared: By summoning an adamantoise, he destroyed the legendary adamantite armor and the town where it was located even before Seiya and his party arrived.
- Enemy Summoner: He summons an adamantoise to destroy the adamantite armor, preventing Seiya from maximizing his defenses. He then summons Crossed Thanatos, a Nigh Invulnerable foe who can follow the party back to the Divine Realm.
- Faux Affably Evil: He's calm and polite towards the party, and doesn't act different from when he was a friendly shopkeeper. However, Rista notes that there's madness lurking beneath his small smile, and he's willing to kill his village and loved ones to support the Demon Lord.
- Kill the Ones You Love: He sacrifices his family, and then himself, to summon Crossed Thanatos. He claims his family accepted their deaths.
- Know When to Fold 'Em: He knew he stood absolutely no chance fighting Seiya directly, so he sacrificed himself and his family to summon something that could.
- The Unfought: He's never directly fought, since he sacrifices his life to summon Crossed Thanatos.
A being Kilkapul refers to as the "ultra god of death."
- Bait-and-Switch Boss: The boss to Kilkapul's bait.
- Creepy Cool Crosses: It wields a large black cross as a weapon.
- Dimensional Traveler: Crossed Thanatos enters the Divine Realm on its own, following Seiya's party.
- The Grim Reaper: Is a mysterious hooded figure that is referred to as the god of death. But instead of a scythe, it wields a large cross.
- Humanoid Abomination: More so than most humanoid demons. The party states it doesn't follow the rules of the world and any attempts to use Scan on it reveals a bunch of random characters in place of normal stat values. Worse yet, Seiya states that it doesn't have the Fake Out skill, which means the garbled strings are actually its real stats.
- In the Hood: It looks like a shadowy humanoid wearing a hooded robe.
- Light Is Not Good: Its cloak is entirely white, but it's the god of death summoned by Kilkapul.
- Nigh Invulnerable: Any attempt to destroy it physically or magically will result in it splitting itself and regenerating. Only Valhalla's Gate is capable of permanently killing it.
- Religious and Mythological Theme Naming: In Greek mythology, Thanatos is the personification of death.
- Self-Duplication: It can split and duplicate itself whenever someone attempts to cut it. Unlike most examples of this though, it never stays that way, as the duplicates always merge back with the real one a short time afterward.
- Skull for a Head: The few times its face is shown, it has the appearance of a skull with grey skin, with its mouth being just a small line and its only facial feature being a giant black hole where its eyes should be.
- The Speechless: It cannot speak at all.

The fourth and final demon general.
- Adaptational Wimp: In the anime adaptation, he doesn't even get a chance to properly fight before he's unceremoniously killed off.
- Blood Knight: He's initially disappointed that he has to fight the elderly Emperor Roseguard, but is pleased when his opponent turns out to be stronger than he looks.
- Early-Bird Cameo: His silhouette can be seen at the end of episode 6 alongside the Demon Lord after they finished constructing Chain Destruction.
- Locked Out of the Loop: Apparently, the Demon Lord never told him that Emperor Roseguard was on their side.
- Multi-Armed and Dangerous: He has a different weapon in each of his six arms.
- The Unfought: Seiya never gets to fight him since he's fought and killed by Emperor Roseguard. Instead, he gets to fight the even more powerful demonic Emperor Roseguard.
- We Hardly Knew Ye: He's mentioned once by Kilkapul, but gets little screentime before he's killed by Emperor Roseguard.
- The Worf Effect: Stat-wise, he's supposed to be the strongest of the demon generals, but is easily defeated by Emperor Roseguard to establish that the latter is Gaeabrande's strongest human.
