The Admirabilis

    In General 
  • Deal with the Devil: They chose to become mindless slaves on the moon to avoid starving to death.
  • Made a Slave: Currently, the majority of the Admirabilis are held captive on the Moon eating Moon dust most of the time. In addition, they've (mostly) been brainwashed to be compliant. Perhaps averted, since the Lunarians claim they came to the moon willingly during a famine but passed on the story poorly to their descendants.
  • No Party Like a Donner Party: In particularly horrible times of famine, the Lunarians noted that the Admirabilis resorted to eating their own young in order to satiate themselves.
  • One-Gender Race: Downplayed. According to the 11th volume's special booklet, female Admirabilis outnumber the males by a ratio of 1000 to 1. They's explosive breeders like many fish species, so they don't necessarily need many males as long as they take care of the rare few well.
  • Our Mermaids Are Different: They're humanoid sea creatures in the water with a very human torso and face but a more fishy tail, but on the surface they're depicted as giant slugs.
  • Out of Focus: Of the three races, they are the least focused on and generally have the least amount of important representatives in the story overall. The last time they were seen in a major way was during the post-Winter arc.
  • Undying Loyalty: Thanks to Phos freeing Aculeatus and helping Ventricosus, and due to carrying the scent of the Ruler, the entire race adores Phos and sees the Gem as a legendary hero. They are ready and willing to help the Gem with any plan, including getting rid of their own shells even if the newer descendants have them decidedly attached to their flesh.
  • Voluntary Shapeshifter: Can take on more human-like forms when in the ocean.
  • We Are as Mayflies: They may not be humans, but they're the closest of the three races to being Humanity. They have genders, reproduce, and have an extraordinarily short lifespan compared to the nigh immortal Lustrous and Lunarians. Phos has to learn this the hard way when they discover Variegatus in Ventricosus' place as King.



Voiced by: Chiwa Saito (Japanese), Luci Christian (English)

The King of the Admirabilis, who manages to strike a deal to free herself and her brother from the Moon People.

  • All Women Are Lustful: She openly lusts over Master Kongo by calling him a "hunk."
  • Attack of the 50-Foot Whatever: Her giant slug form.
  • Baleful Polymorph: Converted into a giant mindless slug to work for the Moon People.
  • Brainwashed and Crazy: At the beginning, when used by the Moon People. Subverted when we later find out that she was the only one they could not brainwash.
  • Brother–Sister Incest: Implied, given Variegatus reigns over a small colony of Admirabilis after the time skip and she and Aculaetus were the last Admirabilis left on Earth.
  • Buxom Is Better: Clearly seems to believe so, though Phos finds her breasts vulgar.
  • Clothing Appendage: Her dress is part of her body.
  • Doomed Hometown: The Moon People wiped out all the Admirabilis.
  • Healing Factor: Her head gets split open during her initial fight with the Gems, but she quickly heals from the damage.
  • Heel–Face Turn: By the beginning of the story she betrays Phos while striking a deal and trying to recover her brother from the Moon People, but eventually regrets her actions and saves him.
  • Heel Realization: Which prompts her to stop her brother against Phos, since she knows they would be the same as the Moon People.
  • Incest Is Relative: It's implied that she and Aculeatus reproduced together, given the lack of any other male Admirabilis.
  • Killed Offscreen: Not killed, but is long dead by the time Phos wakes up and eventually meets her descendant.
  • Last of His Kind: The last of the Rulers. That is, until she has children and descendants.
  • Made a Slave: Like all her species, by the Moon People.
  • Mr. Exposition: Explains the story about the three species, the world and the humans to Phos.
  • My Greatest Failure: According to Variegatus, she regretted tricking Phos during her whole life and until her death.
  • Red Baron: The Ruler Of Shells.
  • Pimped-Out Dress: In her more human-like form.
  • Removable Shell: She is a slug that grows a shell.
  • Requisite Royal Regalia: While they aren't clothes but more like part of her body, they resemble a fancy queen dress.
  • Ridiculously Cute Critter: Her dehydrated slug form is this, even for most of the gems.
  • She Is the King: Despite looking obviously female, she's still considered the King of the Admirabilis.
  • Sole Survivor: Along with her brother.
  • The Good King: If Variegatus words about her are true.



Voiced by: Yuko Sanpei (Japanese), Maggie Flecknoe (English)

The younger brother of Ventricosus, and a warrior. Also captured and brainwashed by the Moon People.

  • Aloof Big Brother: For Ventricosus.
  • Attack of the 50-Foot Whatever: As the giant mindless slug, he is even bigger than his sister.
  • Baleful Polymorph: Converted into a giant mindless slug to work for the Moon People.
  • Big Eater: According to Ventricosus. The smell of food is enough to make him recover his sanity for a while.
  • Blood Knight: Again, according to Ventricosus. He shows to be an incredible fighter himself.
  • Brainwashed and Crazy: Turned into a giant mindless slug, although he gets better and attacks his captors in return.
  • Brother–Sister Incest: Implied, given Variegatus reigns over a small colony of Admirabilis after the time skip and he and Ventricosus were the last Admirabilis left on Earth.
  • Combat Tentacles: In both forms he fights like this, and the tentacles themselves pack quite the punching power.
  • Curb-Stomp Battle: His battle against the Moon People is this. It probably helps that he was angered by years of enslavement.
  • Doomed Hometown: The Moon People wiped out all the Admirabilis.
  • Fantastic Racism: Against the Moon People, with good reason.
  • Killed Offscreen: Not killed, but is long dead by the time Phos wakes up and eventually meets his descendant.
  • Last of His Kind: The last of the Rulers.
  • Made a Slave: Like most of his species.
  • Removable Shell: He is an octupus that grows a shell.
  • The Sociopath: Doesn't seem to have the same moral compass that his sister has and if not for her he could have hurt Phos too.
  • Sole Survivor: Along with Ventricosus.
  • Tall, Dark, and Handsome: Verily so.



Ventricosus' descendant, and the fifth Ruler of the Admirabilis.

  • Accidental Misnaming: Refers to Phos as Pozpopilizliz, as that is how their name passed over when the legend got told and retold.
  • All Women Are Lustful: Calls all the Lustrous beautiful, similar to how Ventricosus lusted over Sensei.
  • And Another Thing...: Used when saying goodbye to Phos, she stops two times and comes back: first to tell them about the Humans—the legend Phos was seeking to hear—and then to tell them that she wishes to go to the Moon, which makes Phos realize that's what Lapis Lazuli wanted them to do.
  • Motor Mouth: She is really talkative.
  • Ridiculously Cute Critter: Like Ventricosus, except she is a nudibranch.
  • Requisite Royal Regalia: Her body looks like a pimped out dress and has an overall princess-like appearance.
  • Sketchy Successor: She was told she lacked the wits the older elders had, so it's possible her people saw her like this.


The Lunarians

Single Sunspot Types

    In General 

Lunarians In General

A species bent on capturing the gems. They come in two models, old models that disappear after being cut down and new models that try to capture gems using weapons crafted from their fragments after it. They are the main source of concern during the story.

  • Affably Evil: Even if they appear nice and outright polite in being cooperative with any potential allies, make no mistake, with only a few exceptions, they are all spoiled to a fault, bored out of their minds, and only in it for themselves and perfectly fine with backstabbing their allies if they don't get what they want from a deal.
  • And I Must Scream: They have been trapped in limbo for millennia and being completely immortal, incapable of escaping it on their own. Much to their dismay and desperation.
  • The Archer: Their normal equipment.
  • Assimilation Plot: Unknown, but according to the legends the Admirabilis and Sensei tell this is their reason for being. They are the spirit of humanity, willing to regain their flesh and bone. In reality, that's not the case. All they want to do is pass on. Even if it would entail the complete annihilation of the human race to do so.
  • The Bard: Many of them do not carry weapons, but music instruments to cheer for the ones who do.
  • Barred from the Afterlife: They are the last souls of humanity, who need prayers to achieve Nirvana.
  • The Beastmaster: Towards the captured Admirabilis.
  • Big Bad: The main concern for the Gems during the story.
  • Bizarre Alien Biology: Phos later discovers they communicate by whistling on Earth. The sound itself doesn't come from their mouths, which are always closed, but from an almost invisible hole located on their necks. They also seem to be made of clouds and dissolve only to regenerate on the Moon, which makes sense given that they are really disembodied souls.
  • Blade on a Stick: Some of their weapons.
  • But What About the Astronauts?: They die, but leave behind facilities that the souls of humanity can use.
  • Death Seeker: Ultimately revealed to be their motive. They are the souls of humanity that just want to pass to the other side, and Kongou is not allowing them to.
  • Dissonant Serenity: They have two modes: blankly smiling (on Earth) and disturbingly upbeat (on the Moon).
  • Flying on a Cloud: They all travel like that.
  • Greed: They are described and shown to be greedy. Sensei even makes mention of them sometimes stealing Gems because they like their color, as he warns Phos.
  • The Hedonist: Being the lowest scum of humanity, they live and breathe for their own desires, but with the punishment of eternity grinding them down, all they got left desiring is a release from it all. Even when the most promising opportunity to finally pass on presents itself, they would rather spend it still clinging to their shallow forms of amusement and entertainments until the end comes for them.
  • Hero Killer: During the story they capture Antarcticite, Ghost Quartz and most of Phos. Before the start of it, they at least have captured nine other gems.
  • Holy Halo: The main figure always has one.
  • Immortality: Is it revealed that none of the Moon People struck down by the gems ever died; instead, they take some time and respawn in the Moon. When killed on the Moon they just respawn instantly.
  • I Cannot Self-Terminate: Their main deal. Aechmea explains that they cannot pass onto the afterlife if Sensei doesn't pray for them, but something is keeping him from doing it.
  • I Shall Taunt You: In capturing the Gems and decorating the Moon with their pieces, the Prince at least is hoping it spurs Sensei into finally doing the job they're supposed to be doing; helping the mutated dregs of humanity pass on.
  • "It" Is Dehumanizing: None of them see Sensei as an actual sentient being, but rather the tool that he's allegedly built to be. He's always referred to as a "tool" or a "machine" by them, particularly by the Prince, even if they acknowledge that the Gems hold sentimental significance to him.
  • Lazy Bum: They do little to nothing on the Moon, preferring to have fun and complain about their problems rather than really working towards their goals. Since they don't have high aspirations and take siestas almost all day, they aren't likely to take harder or longer work—which is the real reason why they don't just do night raids on the Gems.
  • Letting Her Hair Down: Subverted. The sundries (the basic unit) let their hair down after every capturing mission, when it's time to relax.
  • Lost Technology: What they posses is this to the gems, in a way, but subverted with the sole exception of the ability to make the hexagonal diamonds that Sensei is made of.
  • Lunacy: Averted. They live on the Moon, but only attack by day. They are apparently part of a union that demanded they be given time off at night.
  • Monochromatic Eyes: All blank, at least when on Earth.
  • Moon Rabbit: While not noticeable when they have their hair tied down, all the Moon People have rabbit ears, referencing this idea. Aechmea's outburst in Chapter 71 implies they're probably more like horns, or are wisps that can be whatever fits their mood.
  • Necessarily Evil: Thousands and thousands of years waiting for your torturing human desires to disappear don't do wonders on your morality.
  • Neutral Evil: Being the "absolute scum of humanity", they will only act in accordance to their own self-interests. Regardless of how much suffering they inflict on other species, they're too bored to actually find any amusement from it, to the point that they're willing to kill everything related to humanity, but not out of spite or malice, but to end that boredom.
  • Oh, Crap!: Once Phos appears alive and well after being captured they all get a massive reaction of this.
  • Our Souls Are Different: Revealed to be a conglomeration of mutated human souls seeking release and paradise (Nirvana).
  • Perpetual Smiler: All of them. Always. Averted when they are actually on the moon, where they can show a greater range of emotion.
  • Prophet Eyes: They have those while in the land, probably as part of the technology that allows them to battle in the hostile environment.
  • Put Them All Out of My Misery: In chapter 80, Aechmea reveals that Sensei's prayers will affect everything descended from humanity, whether they want to pass on or not. The Lunarians are effectively making the choice for species by trying to force Sensei to pray.
  • Puzzle Boss: The new types, who always come with a new trick to surprise and catch the gems.
  • Solid Clouds: As both them and the Gems can stand in them.
  • Technologically Advanced Foe: Their capabilities — the sunspots they appear from, the clouds they ride on, and the weaponry they use — are all the product of advanced technology and industry, of which the Lustrous have only seen the barest tip of.
  • Theme Naming: All their names end with an "a" (Aechmea, Cicada, Quieta, Barbata).
  • The Stoic: The buff Lunarians are like this. Cicada is an exception.
  • Super-Persistent Predator: They just wont stop coming for the gems. Justified, since they are immortal and any injury delivered to them is just a temporary setback. Eventually, they do stop for 220 years in a makeshift "truce" due to having a bunch of live gems keeping them occupied and amusement on the moon instead.
  • Valley Girl: Hilariously, they seem to talk like this once they are able to. The Prince describes it as them forcing themselves to remain happy despite their inability to pass on to the afterlife.
  • The Voiceless: None of them ever talk. When Phos finally manages to strangle one and ask it enough questions, their pupils come back and they only manage to make a "fu" sound before getting slaughtered by the Amethyst twins. It is eventually revealed that is not that they can't talk, they just don't do it on the Earth since the air on the planet is poisonous/uncomfortable for them.
  • War for Fun and Profit: According to Ventriculous, this is the case with them as per they retain the humanity lust for battle and anxiety for having more. Proven false as their reason for the warfare is nothing but a halfhearted effort to kill their boredom and find a way to die for real, through forcing Sensei's hand with their warfare.
  • Weird Trade Union: They have one that demanded that their work hours be limited to daytime.
  • Who Wants to Live Forever?: The only one of the three species that really adheres to this rule. They've been going through the motions over and over so many times that it's starting to become tiresome for them.
  • Wretched Hive: The Luanrians we see were originally the lowest community of the six Moons, made up of the souls of humans that had once been criminals, deviants, and undesirables. They spent their days tearing each other apart and melding together until Aechmea came into their lives.
  • Zerg Rush: They're individually very weak and not hard to disperse. Generally, the only thing going for them is lots and lots of long-distance weaponry.

    Prince Aechmea 

Prince Aechmea / Enma Kubera
The Prince

A person who is considered to be the Lunarians' leader. So far not much about him is known.

  • 100% Adoration Rating: The Lunarians outright love Aechmea and the effort he takes to free them all from their eternal torment, making him their unquestioned leader by approval.
  • Affably Evil: Gives vibes of this. He doesn't seem to have a real problem with Phos, he even greets them and is willing to answer their questions. On the other hand, he also grinds gems into powder for decorative purposes.
  • Authority Equals Asskicking: Manages to easily handle and defeat the already very strong Phos when he tries.
  • Beauty Mark: Under his eye.
  • BFS: Wields one in battle.
  • Big Bad: Being the leader of the Moon People, he should be the main antagonist for the story. However by the time Phos gets to talk with him it's clear (from his perspective) it's actually Kongou-Sensei the one who is causing most concern in the story. That said, it's entirely possible Prince didn't tell Phos the entire truth regarding that matter.
  • Bishōnen: If he even has a gender, although he decisively looks manlier than the other Moon People.
  • Can't Hold His Liquor: The other Moon People comment on how easily he gets drunk.
  • The Chessmaster: His specialty is directing his people and his allies into whatever situation he deems the most necessary for them to pass on. His partnership with Phos and some of the Lustrous has barely any benefits for the Gems, especially with all of the secrets he deliberately withholds from them. Chapter 88 reveals he planned a good chunk of Phos' life, observing them since as early as the first chapter, to make a human to activate Sensei.
  • Coat Cape: Wears his suit like this when receiving the Gems that willingly go to the Moon.
  • Dissonant Serenity: Replies to Phos rampage with a deadpan "Wow.", and doesn't seem impressed at all even when he is being cut in half.
  • Embarrassing First Name: He doesn't like being called by his name or even having one. It turns out Aechmea isn't his real name, but rather a name that the remaining Lunarians call him. His real name is Enma.
  • Even Evil Has Standards:
    • He refuses to disguise Cairngorm as Antarcticite, refusing to compromise Cairngorm's identity in this way.
    • He refused to pass on to the afterlife despite qualifying because he wanted to care for the lowest of the low Lunarians, those who were imprisoned on the smallest moon and refused access to Adamant while he still functioned.
  • Everyone Calls Him "Barkeep": All of his subjects call him Prince, but he assures Phos that it's not his name, but a title.
  • Evil Counterpart: To Sensei. He fulfills Sensei's role of the leader of their respective races, and prioritizes their well being over the rest of the humanity subspecies. However, while Sensei is usually unwilling to hurt anyone to keep the Lustrous safe, Aechmea regularly plays dirty in order to accomplish his goals.
  • Exact Words: He says the captured Gems are "All around". In his defense, he is not wrong.
  • From Nobody to Nightmare: His origins were as a humble office clerk. However, once all the "worthy" Lunarians had passed on to the afterlife, he remained behind to try to help those left imprisoned on the smallest moon, and as a result became the leader of the Lunarians.
  • Go-Karting with Bowser: The first thing he does after defeating Phos and showing them the bodies of their entire species? Invite them for a tour and a fancy dinner. Played with in that he is actually trying to negotiate with the gems.
  • Happily Married: To Cairngorm, as seen after the 220 year time skip.
  • Huge Guy, Tiny Gem: Has this dynamic with most Gems he comes into contact with, but especially Cairngorm, with him being a good two or three heads taller than them.
  • Interspecies Romance: With Cairngorm, a gem.
  • The Leader: For his kind, the others seem to look up to him.
  • Lean and Mean: He is lean compared to Sensei, although not if compared with the rest of the gems. As for the mean part, one of the first things he did upon meeting Phos was to grind a piece of fake Antarc into dust right in front of their eyes.
  • Man of Wealth and Taste: Once it's night, he changes his Buddhist attire for a white suit. He also dines on lotus petals and seems to have impeccable manners.
  • Meaningful Name: His true name, Enma, is a reference to the Japanese version of the Buddhist King of the dead Yama. Like Yama, the Prince is in charge of what's basically Lunarian Hell, Kubera.
  • Mr. Exposition: Regarding the Moon People, Kongou, the Humans, and other things he tells Phos when they meet. He's also the primary reader authority on the backstory of the Admirabilis and what is affecting the Gems.
  • Not So Different: Just like Phos before their transformation being the useless "scrap" of the Gems, the Prince thinks that he and his people are the "scrap/dregs/trash" of humanity, due to all of their efforts to spur Sensei into action failing.
  • Not So Stoic: He's furious when he talks to Cairngorm after the night raid on Sensei's school; he looked more like an Oni than a human. Phos also mentioned he once blew out a wall when he was mad.
  • Sickeningly Sweethearts: With Cairngorm.
  • Villain in a White Suit: Is the Big Bad and wears entirely white suits. He also has the impeccable manners and affable front associated with the trope.
  • Villains Never Lie: For all of the atrocities Aechmea has committed over millennia, he has never once lied about his people's intentions nor the overall situation. Now hiding and manipulating that information is a different story.
  • Voluntary Shapeshifter: Can take on different looks at will.
  • Well-Intentioned Extremist: He wants every Lunarian to be able to pass on to the afterlife. Unfortunately, the only way to do so is for Adamant to pray for them, which will result in the destruction of all life regardless of whether they want to enter the afterlife.
  • You Gotta Have Blue Hair: Ichikawa's colored artbook depicts him with pink hair. This is unusual even for Lunarians; Barbata is shown to have normal brown hair.



  • Accidental Misnaming: Initially fails to pronounce Phos's name, though he later gets it right.
  • Badass Adorable: He's a friendly dizty man out of combat, but within it he's vicious, tossing aside attacking gems like they're minor inconveniences.
  • Bruiser with a Soft Center: He is a muscular, tall Lunarian who is great at fighting. Besides that he seems to be pretty incompetent and warms up to Phos almost instantly.
  • Cool Mask: Wears a terrifying oni-like mask when in combat.
  • The Ditz: An airhead.
  • Dub Name Change: The English translation of the manga refers to him as Cicada (his initial name was Semi).
  • Dumb Blonde: He's been portrayed as a blond in full color Ichikawa art and as noted, he's pretty dumb.
  • Four-Star Badass: Apparently a General, although the Prince notes Lunarians tend to use words whose meaning they don't really know. As for the badass part, he is capable of keeping five gems at bay with no effort, Bort being one of them.
  • Freudian Slip: His very first appearance has him having a case of this, revealing that Prince sent him to observe the Gem. Given the situation, Phos doesn't mind.
  • Huge Guy, Tiny Girl: When hanging out with Phos.
  • Improbable Weapon User: Wields a Vajra for combat.
    • Later uses a spear that has a rebreather-like construction on the end so he can talk to Phos in Earth's atmosphere and stab Phos at the same time.
  • Let's Get Dangerous!: He is surprisingly competent as a warrior, even managing to give Bort trouble.
  • Lima Syndrome: He obviously got way more attached to Phos than the other gems, to the point he returns to the land solely to be sure that Phos is doing fine out of worry.
    • When other gems go to the moon and then want to go on a mission back on Earth, he's adamant about going to protect them even if they are traveling at night, a time when Lunarians never mount attacks.
  • Super Strength: Enough to send four gems flying in one swing. And even then it's clear he wasn't fighting seriously.



The Prince's personal fashion designer.
  • Easily Impressed: Loves the gems at first sight and immediately starts making them outfits.
  • Fashion Designer: Designs the Prince's clothes and begins to design for the gems as well.
  • Meganekko: A bespectacled and sweet fashion designer.
  • Nice Guy: The sweetest of the Lunarians so far, rivaling Cicada.
  • Non-Standard Character Design: Unlike most of the tall, elegant Lunarians she is noticeably short and squat with nearly cartoonish proportions.
  • The Short Guy with Glasses: Visibly much shorter and pudgier than the rest of the elegant and tall Lunarians and a genius in fashion design.
  • Unlimited Wardrobe: Discussed in relation to the Prince. Since the Moon People are immortal, she says she's designed the Prince plenty of clothes and has had nothing more to do for thousands of years, so she fell into a creative rut before the gems come along.


A researcher that works with data on dusted gems.
  • The Everyman: The most "human" of the Lunarians, commenting on what gender the Gems are supposed to be, the meandering nature of Phos' plans, and the creepy undertones of his leader's wedding.
  • Hidden Depths: He likes to cook way more than he does researching, as we see during Prince's wedding reception.
  • Meaningful Name: In some languages, Barbata means "the bearded one". He sports a small goatee.
  • The Mentor: Serves as one for the Moon Gems, particularly Amethyst 84, as they become accustomed to Lunarian technology. He essentially replaces Kongou's role in their lives, with them even calling him Sensei.
  • Nice Guy: Apologizes to Phos when he must give them a Sadistic Choice, showing sympathy for their situation, and is the only Lunarian to show concern about Phos's welfare when Phos is shattered by the Earth gems.

    The Moon Princess (spoiler) 
See Cairngorm.

Double Sunspot Type



The first Double Sunspot to appear, a giant six armed creature that fights Bort, Phos, Diamond and Alexandrite. He was also Kongou-Sensei's pet.

  • Ascend to a Higher Plane of Existence: His eventual demise. And probably, being from the Moon, exactly what he wanted.
  • Attack of the 50-Foot Whatever: Shiro, by all accounts, is one of the biggest Lunarians that the Lustrous ever laid eyes upon.
  • Baleful Polymorph: He is actually a dog from back when Humanity used to live, and one that Kongou loved at that. He ended up unable to reach the Other World and took on the Shiro form after landing on the Moon.
  • Bare-Handed Blade Block: Pulls this move on Diamond without even looking.
  • Cloud Cuckoolander: As he acts like a dog. He gets struck on his own sunspot during his first onscreen fight and is put down just by Sensei telling him to sit.
  • Cool Pet: Apparently Sensei's.
  • Curb-Stomp Battle: One of his halves is in the receiving end of it against Red Alex.
  • Cuteness Proximity: Bort, Diamond and Yellow Diamond all react like this when encountering his smaller forms. Rutile, not so much.
  • Eyes Do Not Belong There: Has six eyes on his face and his copies grow eyes in very different places.
  • Finger Poke of Doom: Does one in the most nonchalant manner possible on a blocking Dia, which sent the poor Gem flying into the ceiling like a marble.
  • Fluffy the Terrible: Shiro is considered a very commonplace name for dogs, and is usually the equivalent to a name like "Fluffy" or "Snowy" in Japanese. This guy is a monster in size and in skill, by contrast. Not so much in his true form.
  • Ghostly Goals: To get permission from his owner to pass on.
  • Handshake Substitute: When encountering Kongou, they both fist bump.
  • Immortality: Splits when cut down.
  • Knight of Cerebus: As far as fights in the series go, as he is one of the first enemies to have a lengthy fight, especially against Diamond, and overall gives the gems far more trouble than the average Moon People.
  • Little Bit Beastly: One of his more divided forms looks humanoid, but with fur and several eyes.
  • Me's a Crowd: Can split into different beings when cut. Eventually there are hundreds of him, though his power also divides and so they are inoffensive.
  • Multiarmed And Dangerous: Has four to six arms depending on his shape.
  • Old Friend: Was Sensei's pet back when he was a dog.
  • Pokémon Speak: Played with. For the Gems, his "Woof" barking noise sounds like this, as none of them have ever seen a dog before. Because of this Phos just names him "the Woofwoof".
  • Prehensile Tail: Which he uses to fight.
  • Ridiculously Cute Critter: His smaller, three eyed dog form.
  • Sniff Sniff Nom: He is seen sniffing Sensei's robes in one scene. Just like a dog would do with his owner's clothes after a long time separation.
  • Stealthy Colossus: For something of his stature, he displays shocking degrees of stealth, capable of vanishing as into thin air on occasion.

    The Pieces 

The Pieces

The second Double Sunspots to appear. They look like Shogi pieces.

  • Animate Inanimate Object: They are board game pieces come to life. Their existence seems to follow the idea about objects held dear receiving a soul after 100 years or more (tsukumogami).
  • Ascend to a Higher Plane of Existence: Like Shiro, Kongou releases the pieces at the end and they disappear into nothingness. They look happy and teary eyed about it.
  • Ghostly Goals: To be played with one last time by their owner.
  • Gradual Grinder: Their method of fighting. They take small fragments and shoot them at the gems, then taking more fragments from the ruptures, and shooting themselves again, and so on. With this method they eventually set up a situation on which Phos, Caigorm, Peridot and Sphene are all incapacitated and near captured.
  • Happy Fun Ball: They look like some inoffensive pieces of a Board Game but are quite adept at fighting the gems.
  • Psychological Combat: As part of their strategy, they use specific fragments that are from the captured partners of the gems they face, in order to confuse and bait them.
  • Schmuck Bait: They attract the gems by showing them fragments of their lost partners and then shooting them at them
  • Wrecked Weapon: They break both Bort and Tourmaline's swords. In response, the latter shocks them with electricity while the former just cuts them up with their own hair.
  • Zerg Rush: Basically how they manage to defeat the bigger and stronger gems.

Triple Sunspot Type



The first and only Triple Sunspot to appear yet, a silent doctor-like figure that unnerves everyone.

  • An Arm and a Leg: Has a leg missing and replaced with another flowery decoration.
  • Anti-Climax: She appears in such a way that it seems she is about to trash the gems. She stands up and... Does nothing. Her visage however is enough to temporarily break Sensei's calm demeanor.
  • Ambiguous Gender: Being a Lunarian, it probably has no gender whatsoever, but it's later revealed to have been a woman—specifically, an imitation of the human woman that created Kongou.
  • Badass Labcoat: Signifying that she probably was an investigator, though much can't be said.
  • The Faceless: Her face is covered by a flower-like thing.
  • Half the Man He Used to Be: How Phos puts her down.
  • Identical Stranger: Implied to be one to a person Kongou-Sensei knew, most likely a human professor. Later confirmed to be a copy of his creator.
  • The Quiet One: If she can even talk.
  • Knight of Cerebus: Manages to be this while doing absolutely nothing as she entirely kicks Phos suspicions about Kongou-Sensei which in turn makes him go to the Moon.
  • Light Is Not Good: Is entirely white and shines, but it comes from the Moon and it's definitively an enemy.
  • Mystical White Hair: Has it.
  • Nothing Is Scarier: She can move, as she stood up after falling from her sunspot, but prefers to just wait until being cut down. Her attitude unnerves Zircon and even Bort, whose hands are shaking when the gem prepares to strike her down. The reveal that she is a copy of Kongou's creator makes it obvious that she works exactly like the Main Figures from the vessels that attack the gems, which just stand there until cut down.
  • Peek-a-Bangs: Her hair covers half her face and would cover an eye, if she had one to.


    The First Machine 
The machine made by humans before Kongou. Considered his "Brother" by the Lunarians.
  • A.I. Is a Crapshoot: According to Barbata, the machine purposefully miscalculated the trajectory of an incoming meteorite in an attempt to rid the world of humans, as it thought that Humanity was not fit to be the apex predators. The remaining humans at the time dismantled it once they realize what happened.
    The Ice Floes 
Whispers heard under the ice during Winter, from human souls of dregs and sinners that inhabit the ice.
  • Jerk with a Heart of Gold: They have encouraged bad behaviour from the gems, such as tempting Phos into putting their arms in the ice (and breaking them off when Phos fell in) and tempting Cairngorm to suicide, but they also showed concern for Phos when Phos began to be overwhelmed by their whispers.
  • Become a Real Boy: They all remember what it was like to be human, and sometimes call upon the Lunarians in the hopes that they can be human again.
  • Was Once a Man: They're what's left of humanity after their genetic data got scattered into the waters.


How well does it match the trope?
