Amaterasu

In General

• Badass Crew: Amaterasu undoubtedly becomes this as the series goes. By the second arc of the plot, they can take on a Physical God and win.
• Battle Harem: The main female cast of Amaterasu becomes Kizuna's harem since they all derive power from his Eros, but it only becomes possible when each HHG develops genuine affection for him.
• Everybody Has Lots of Sex: By necessity. Heart Hybrid is essentially foreplay which is done to heal the HHGs and restore their energy levels. Climax Hybrid is the next stage, requiring much more sexual acts. It gives each HHG a massive surge in power and unlocks their hidden "Immoral Weapon". At the end of the series the cast discover the Ecstasy Hybrid, which requires them to actually have sex. This one puts them on the same level as a Physical God.
• Multinational Team: Kizuna and Hayuru are Japanese, Yurishia is American, Silvia is British, Aine is unknown due to her Mysterious Past. It's later confirmed that she comes from another dimension.
• True Companions: Aine, Hayura and Yurishia weren’t very close when first introduced, but thanks to Kizuna’s arrival, Amaterasu fully becomes a united team.

Kizuna Hida

Captain Kizuna Hida

The central protagonist of the story. He was implanted with the first Heart Hybrid Gear (HHG) core called 'Eros' as a child in an experiment conducted by his mother. However since men have a low compatibility with HHG, his armor has low offensive capabilities. His primary function is to perform Heart Hybrid with his teammates to restore their Hybrid Count. If he also achieves Climax Hybrid Kizuna’s Eros temporally copies the abilities of the HHG of his partner. If the partner has a HHG of the 'Ros' series, they will also gain access to their Immoral Weapons.

---

• Accidental Pervert: Thanks to his sister.
• Age-Gap Romance: With his sister, Reiri, who's his parental surrogate and technically old enough to be his aunt. Despite being blood related and 10 years younger, Kizuna admits that he's sexually attracted to her. She eventually becomes one of his main partners for Climax Hybrid and by the end of the series, he has unprotected sex with her on an almost daily basis.
• Ambiguously Absent Parent: His mother is a very important character in the series, but his father is never even mentioned.
• Audience Surrogate: He is a New Transfer Student, making him the main target for exposition about Ataraxia and the conflict with the AU.
• Babies Ever After: By the epilogue he has a daughter and a son born to Grabel and Zelshione respectively, and he impregnates Reiri.
• Barrier Warrior: Heart Hybrid Gears can only show their true potential when they are installed in females. However, because males can't use them to their full strength, their Hybrid Count is consumed slower, so they can keep their barriers up for longer. So whenever Kizuna is not fighting with his Power Copying ability, he is usually acting as a living shield for his teammates. However, he later shows that those barriers can also be used offensively, as show with his There Is No Kill Like Overkill method to defeat Clayda.
• The Big Damn Kiss: With Aine at the end of volume 6.
• Big Sister Attraction: Made explicit by the narration of the volume 13 epilogue chapter, during the scene when he and Reiri are having sex in the command center's conference room. It states that he's physically and emotionally attracted to her, and that the only time Kizuna feels he can be completely honest about his body's desires is during his Climax Hybrid sessions with her.
• Big Sister Worship: Kizuna idolized Reiri when he was a child. In the present he keeps it to himself most of the time, but the admiration is still there.
• Brother–Sister Incest: In volume 5 Kizuna ends up doing Climax Hybrid with his sister Reiri because there's literally nobody else left. It happens a second time in volume 8, because the process to create an Immoral Weapon for Eros requires a supply of magic power from "an existence that is close to Kizuna." And then a third time in volume 10, this time to install a Core in Reiri. By the time of the Harem Hybrid, they have become so comfortable with doing sexual things with each other they only remember such a thing is supposed to be a taboo when their mother points out.
  • In the epilogue of Volume 13, He engages in Ecstasy Hybrids with her during his free time. The narration points out that Kizuna gives in to his urges more easily with Reiri.
• Calling the Old Woman Out: He gives one on Nayuta, but she is unfazed.
• Chick Magnet: Kizuna's harem never stops growing.
• Combat Pragmatist: Kizuna may be a Nice Guy, but that doesn't mean he won't play dirty to win.
• Dark Is Not Evil: His suit of armor looks dark and he is the main hero of the story.
• David vs. Goliath: The climactic battle of volume 6, where Kizuna battles against Aine. True to the myth, Kizuna wins.
• Determinator: Even when he is fighting opponents clearly stronger than him, like Grabel, Zelshione, or Aine, Kizuna does not give up.
• Did You Just Punch Out Cthulhu?: With the help of Aine and Grace, Kizuna manages to defeat his mother after she became a (incomplete) Physical God. This ultimately becomes the main plot of the next major arc of the novel: Kizuna and his Battle Harem have to defeat the four Deus Ex Machina, a group of Physical God that created the world they live in.
• Did You Just Romance Cthulhu?: Kizuna has done Climax Hybrid with every Physical God he defeated, excluding Thanatos.
• The Dreaded: To the people of the Batlantis Empire after they witness him subduing Grabel and then rampaging violently in the Colosseum. They even start calling him "The Demon King of Lemuria".
• Embarrassing Nickname: Demon King Eros. Obviously he was not happy to find out this nickname his classmates gave him.
• Extreme Libido: While not to the same extent as Reiri, Kazuna's sex drive increases as his harem increases. By the final volume, he engages in full-on orgies with the women of Amateratsu that last for hours on end.
• Guile Hero: Best demonstrated in volume 6. Facing an enemy much stronger than you? Lie through your teeth to mislead her and strike where she is not expecting!
• The Heart: He is the one that helped the girls when they were in their lowest moments and thus changed Amaterasu into a solid team of True Companions.
• The Hero: He is the one that leads Amaterasu as they finally achieve important victories against the AU.
• Heroic Willpower: He manages to resist Zelshione's hypnosis.
• Meaningful Name: His name can be mean "no injury", but can also means "bonds", which one of the chapters name is "Bonds".
• Marry Them All: He has well over 2 dozen women interested in him, two of which give birth to his children (Grabel and Zelshione), yet he takes on Aine, Yurishia, Hayuru, Silvia, and Reiri as his wives due to them being in love with him for him as a person rather than an object of lust. It helps that he loves them all as well.
• Multi-Way Sex: Several of those happen in the last stretch of the series when most of the girls have made peace with the fact that it's necessary to win, but the standout example is the huge orgy that happens in Volume 12, referred to as "Harem Hybrid".
• New Transfer Student: His sister uses her authority to enroll him in Ataraxia.
• Nice Guy: Cares deeply for his teammates and always does his best to help with any problems they might have. Later volumes show that he also doesn’t hold grudges against former enemies.
• No Range Like Point-Blank Range: Part of his overkill method for defeating Clayda. He also defeats Nayuta by firing Aine's BFG at point-blank range.
• Official Couple: With Aine. Albeit in practice he sort of is in a Polyamory relationship with his harem, as he still needs to perform Ecstasy Hybrid with them.
• One-Steve Limit: Subverted. Zelshione and Grabel name their respective son and daughter after him.
• Overranked Soldier: After his first actual battle, he is immediately granted the rank of Captain. Justified, because he is the only one who can recharge the girls' Hybrid Gears.
• Negated Moment of Awesome: As Grabel is delivering a huge Curb-Stomp Battle to his teammates, Kizuna takes a stand despite his injuries, rushes to take this new opponent head on… and gets blown away so easily even Grabel is surprised. Although he got his revenge on her later.
• Parental Abandonment: His mother kicked him out of her lab once she found a better experiment subject.
• Parental Incest: The reinstallation of Kizuna’s Eros requires him to do Climax Hybrid with Nayuta. He doesn't like the idea at all, but his mother does not give him a choice. She even gets Reiri to join them for a Connective Hybrid!
• Polyamory: He eventually weds all the women of Amateratsu, though Reiri holds the distinction as his Top Wife. Grabel and Zelshione would also be among his harem had they not gone back to their worlds and both give birth to his son and daughter respectively.
• Power Copying: Eros can use the normal abilities of a Hybrid Gear after Kizuna helps its wearer achieve a Climax Hybrid. And if he achieves a Connective Hybrid, he can use the abilities of both his partners at the same time.
• Real Men Wear Pink: Different Heart Hybrid Gears release luminescence of different colors after Climax Hybrid. Eros is pink.
• Red Baron: Played for Laughs, his classmates have nicknamed him Demon King Eros. Played Straight when the people from the Batlantis Empire start calling him "The Demon King of Lemuria".
• Secret-Keeper: His sister informs him that the "-ros" series of Hybrid Gears will kill their pilots if their Hybrid Count reaches zero, and he agrees to keep it a secret from the other members of Amaterasu.
• Sex God: His sex drive increases over the course of the story. By the time of Volume 13 he becomes amazing with sex to the point he is able to have Threesomes, Foursomes, and later numerous orgies for hours on end. the women he takes on as his wives: Aine, Yurishia, Hayuru, Silvia, and Reiri are all amazed by his sex drive.
• Sleeping with the Boss: Reiri is the Captain of Ataraxia's military, which makes her his commanding officer. But that isn't the only "service" she's interested in, which is why she gives him days off so he can service her.
• There Is No Kill Like Overkill: How he defeats Clayda, one of the Quartum: He overloads his magic gun with magical power and fires it from point-blank range, after surrounding her body with his barriers so that the impact from the blast together with the excess of magic power will bounce back at her.
• Unequal Pairing: Kizuna has to keep his relationship with Reiri a secret, because she's his commanding officer which is a breach of protocol that could potentially cost Reiri her job and risk Kizuna being expelled. There's also the age difference to consider, in addition to the incestuous aspect, with Reiri being old enough to technically be his aunt.
• Unresolved Sexual Tension: With Aine. It becomes clear as the series goes that the two have strong feelings for each other, with the other girls in his harem even commenting on how Aine is the obvious lead in the dispute for Kizuna's heart. Alas, they never get the chance to talk and solve the tension thanks to all the fighting going on around them. It finally gets solved at the end of the series, with the two confessing their love for each other and having sex together.
• Weak, but Skilled: The main reason Kizuna was able to defeat Aine. He planned the entire battle beforehand, waited for the right moment to attack and destroy her strongest weapon and outright lied to her through a fake Badass Boast to mislead her. Being a huge Determinator also helped.
• "Well Done, Son" Guy: The poor guy desperately wants his mother's affections and approval, even after she flat out tells him she no longer needs him. At first. He drops whatever love he had for her after learning that she's a Well-Intentioned Extremist who is willing to let humans die for the sake of her experiments.
  • Though he does somewhat fall back into this trope during the second half of the story. After spending time with his mother when she became a Physical Goddess and the leader of the group, he starts to reconnect with her. By the very end, just before Nayuta passes on, she offers him a genuine praise at how well he has done. Upon hearing this, he was unable to stop himself from crying.
• Wholesome Crossdresser:
  • Because the humans that live in Batlantis are an One-Gender Race, Kizuna has to cross-dress to infiltrate among them.
  • He does it again when he has to perform Climax Hybrid with Valdy, who has trouble dealing with men.

Aine Chidorigafuchi

Princess Aine Chidorigafuchi (born Ainess Sinclavia)

A prominent member of Amaterasu. Aine is a mysterious girl who has no memory of her childhood. Her HHG is called 'Zeros' one of the 'Ros' series. It's incredibly fast, but has no weapons, so Aine fights using her bare fists. Her Immoral Weapon is a very powerful particle cannon called "Pulverizer".

---

• The Ace: All her experience fighting with her bare fists means that she is easily the best fighter in the series in terms of close-range combat. Awakening her Immoral Weapon means that now she also has a devastating weapon to use if she ever needs to fight at distance. And that's assuming she won't simply destroy everything in an instant with her Forbidden Weapon.
• Anti-Magic: Her Forbidden Weapon, Code Breaker, deactivates all magic in an area, including other HHG.
• BFG: Aine's Zeros can gain access to the Immoral Weapon "Pulverizer", which functions as a man-portable Wave-Motion Gun.
• Big "NO!": After Genesis is destroyed.
• Cain and Abel: The Abel to Grace's Cain, especially when the latter is going through a Sanity Slippage.
• Close-Range Combatant: Before Kizuna arrived, Aine didn't have any long-range weapon. Even after getting an Immoral Weapon from him, she still has to fight mostly in close-range, as an Immoral Weapon can only be used temporally. It's not until she awakens her Forbidden Weapon that she gains a reliable option for long-range combat.
• Conflicting Loyalty: After remembering that she is a princess of the Batlantis Empire and more importantly, that her home world is going to be destroyed if they stop stealing magic power from the humans of Lemuria. Aine tries her best to find a solution that would benefit both sides, but she can't really decide which world she belongs to and the inner conflict stops her from making any real progress until Kizuna beats some sense into her again.
• Cool Big Sis: To her little sister Grace, at least when they were younger
• Deuteragonist: After Kizuna, she is the most important character in the story. Becomes even more obvious after she recovers her memories and goes back to Batlantis. For 2 whole volumes the narration keeps switching between following Kizuna's adventure and telling the story of Aine's identity crisis.
• Extreme Doormat: Aine goes through a period of identity crisis after recovering her memories, and as a result of that she ends up doing whatever Grace or Zelshione tells her she should do.
• First Girl Wins: Subverted twice.
  • While Aine is the first girl Kizuna meets after arriving at Ataraxia, he had already spent years growing up with his big sister Reiri. Thus, making Reiri the actual "first" girl.
  • Also, despite being the one he ultimately gives his virginity to, the one he most often has sex with is his sister, Reiri. Which causes Aine and the rest of the harem to complain that she's monopolizing him, since he has a responsibility to perform Climax Hybrid with them too.
• Friendless Background: Aine has no memories from her first 10 years of life, and she spent most of her life after that as a test subject in Nayuta’s lab, so she has no friends. Even after joining Amaterasu, she kept herself distant from her teammates. Kizuna’s arrival finally changed that.
• Good Old Fisticuffs: Zeros has no weapons, so Aine fights using her fists. This leads to her being Overshadowed by Awesome, since she needs to defeat Mecha-Mooks one by one, while Hayuru and Yurishia can use their weapons to slaughter them en masse. It's the main reason she wishes to get her Immoral Weapon as fast as possible.
• Heroic Willpower: When Zelshione hypnotizes her into attacking Kizuna, she is able to wake herself up in time.
• Holy Halo: A halo appears on her back when she activates Code Breaker.
• I Just Want to Be Badass: Since Aine doesn't remember anything from before she was taken in by Dr. Nayuta, she feels that using a Hybrid Gear is the only thing she can do. As a result, she really hates how her teammates are always overshadowing her, and is constantly pushing herself more than it’s healthy for her body. Kizuna helps her get over it.
• Inferiority Superiority Complex: She likes to boast about being the World Strongest Woman but in reality she is just trying to hide how insecure she is about her record as a Heart Hybrid Gear pilot, due to her always getting overshadowed by Yurishia and Hayuru. She gets better, thanks to Kizuna teaching her to value herself as more than just a Heart Hybrid Gear pilot.
• Leeroy Jenkins: A side effect of her extreme I Just Want to Be Badass attitude. Aine usually rushes into battle without any consideration for strategy or her own well-being. She gets over it with Kizuna’s help.
• Line-of-Sight Name: She was named Chidorigafuchi because that's the name of the canal where she was found.
• The Mirror Shows Your True Self: In episode 7, Aine has a strange dream where she's wearing nothing but a tiara and a completely transparent dress, but her reflection depicts her in her combat suit. Turns out to be Foreshadowing to her status as a princess of the Batlantis Empire and the identity crisis she will go through when she discovers this.
• My Hero, Zero: Her Heart Hybrid Gear is Zeros.
• Mysterious Past: Aine has no memory of her past before being taken in by Dr. Nayuta Hida as a test subject for the Hybrid Gear technology. At the end of Volume 4, she is revealed to be Aines Sinclavia, Princess of the Batlantis Empire.
• No Social Skills: It's hard to have those when as far as you remember you spend your whole life locked inside a lab. Before Kizuna arrived, most of Aine's "social interactions" consisted of her either boasting her skills or snarking at people.
• Official Couple: With Kizuna. Although from the point of view of the others, she is just the Top Wife. But she doesn't plan to let them have their way.
• One-Man Army: After she recovers her memories and awakens Code Breaker. The first thing she does with it is to wipe out an entire fleet and disarm every fighter in the city.
• Potty Emergency: Aine has one in Episode 12, complete with Potty Dance. But thanks to Kizuna, she doesn't make it...
• Power Dyes Your Hair: The hair of the members of the royal family of the Batlantis Empire, including Aine, turns pink after they come in contact with large amounts of magic power. Since the amount of magic power in the air of Batlantis is much higher than in "Lemuria", their hair permanently turns pink if they live there long enough.
• Puppet King: A complicated example. Grace fully plans on giving Aine her title of Empress and all the power that comes with it, but due to her insecurities and a bit of an identity crisis, Aine mostly just goes along with whatever Grace or Zelshione tells her to do, and overall doesn't look like someone who actually has power.
• Really Royalty Reveal: The reveal that Aine is a princess coincides with the reveal that Zeros was hiding a Story-Breaker Power.
• Reluctant Fanservice Girl: When she becomes Empress of Batlantis, she becomes very embarrassed by the really skimpy royal uniform.
• Riddle for the Ages: It is never really explained how or why she was sent to Lemuria as a child and lost her memories.
• Shout-Out: The halo that appears on her back when Code Breaker is activated, coupled with the mostly white color scheme of her HHG makes her look like an anthropomorphized Stargazer Gundam. But what Code Breaker actually does turns it into a Magitek version of the Moonlight Butterfly.
• Smug Super: She's one of the strongest characters in the series and won't let you forget it. Its kind of a Double Subversion. It's soon made clear that Aine suffers from the Inferiority Superiority Complex, but while Kizuna helped her get over it, he also gave her access to the very powerful Immoral Weapon. So Aine's boasting became justified, but only after it became more subdued and less unhealthy.
• Story-Breaker Power: Zeros can use a Forbidden Weapon called Code Breaker that can deconstruct any type of Magitek, be it a Heart Hybrid Gear or one of the Mecha-Mooks. If Aine had not lost all of her memories, there wouldn't have been much of a plot.
• Top Wife: How the other girls see her position. Although she doesn't mind polygamy, she still won't let the other girls have full control over Kizuna.
• Unishment: When the portal between the worlds is about to close forever, Grace realizes she will be miserable without Kizuna. So Grace quickly pulls a coup d'état to regain her title as Empress, with the official reason being that Aine showed weakness by crying in public, making her unworthy, then sentences Aine to be exiled from Batlantis. Everyone realizes what Grace is doing and Aine happily goes through the portal to be with Kizuna.
• Unresolved Sexual Tension: With Kizuna. It becomes increasingly obvious as the series goes that the two have strong feelings for each other, but they never get the chance to talk about their relationship thanks to all the conflicts they are dragged into. It eventually gets resolved in the last volume when they defeated the last of the Deus Ex Machina and have Their First Time.
• Walking Spoiler: A good section of the plot can't be talked about without revealing that she's a princess of the Batlantis Empire.

Yurishia Farandole

Yurishia Farandole

A beautiful young woman who was once the Ace of the American team of HHG users, 'Masters' before shifting to Ataraxia and becoming part of Amaterasu. Her HHG is called 'Cross' another of the 'Ros' series. Yurishia is a specialist at long range combat, but ironically her Immoral Weapon "Cross Head" has a range of only one meter despite its devastating power.

---

• Ascended Fangirl: When she was a child, Yurishia liked to read superhero comics. Naturally, when she discovered Heart Hybrid Gear and managed to become the pilot of one, she felt like a childhood dream had come true.
• Beam Spam: Yurishia's Hybrid Gear can deliver these by firing her particle cannons and the "Differential Frames" on her shoulders at the same time. And boy, does she loves delivering those.
• Big-Breast Pride: Yurishia usually doesn't boast about her breast size... unless she is teasing her teammates or trying to seduce Kizuna, that is. Then she fully embraces this trope.
• BFG: Her Immoral Weapon, "Cross Head."
• Brainwashed and Crazy: Twice. First she is brainwashed by Zelshione and made to attack Kizuna. Several volumes later, she gets brainwashed by Osiris into believing she is her daughter.
• Broken Pedestal: For Scarlett. The girl used to idolize her. Until that one mission where Yurishia send her and the other Masters into a battle against an A-class enemy while she took care of an army of small fries. And then she showed up right on time to finish the weakened A-class and received all the glory. The fact that she refused to explain her actions didn't help.
• Covert Pervert: Yurishia looks and acts the part of a Proper Lady, in public, because it's what's expected of her. But she's secretly a masochist, who's heavy into S&M. It's subverted by volume 10, when she drops the facade by wearing the dog collar Kizuna gave her in public, as proof of his ownership of her.
• Dual Wielding: With two particle cannons.
• Happiness in Slavery: By her own admission^note during the volume 13 epilogue chapter, once she finally becomes Kizuna's pet/sex slave.
• Identical Stranger: She looks just like Osiris's long dead daughter, Isis. This causes problems.
• Inconsistent Spelling: Her Hybrid Gear is either Cross or Kuros.
• Interplay of Sex and Violence: Yurisha is a masochist and a sexual submissive, who derives pleasure from Kizuna "punishing" her through BDSM. She also gets off on verbal abuse, so she begs him to bully her and says that the welts he leaves on her backside are proof that she belongs to him. Just as she achieves orgasm, she loudly proclaims that she wants everyone to know that she's his slave.
• Kissing Under the Influence: Not kissing, but something to the same effect. During the climax of volume 7 Yurishia and Hayuru are seen intensely groping each other thanks to the aphrodisiac effect of Kizuna's Connective Hybrid with Aine and Grace. There isn't any other scene in the series that implies they are anything but straight.
• Long-Range Fighter: Naturally, as Cross is only equipped with guns. Scarlett was in total disbelief when Yurishia told her that her Immoral Weapon only had a range of one meter.
• Onee-sama: They are both American, but the relationship she had with Scarlett before things went sour fits this trope very well. Scarlett saw her as a role model while Yurishia saw the younger girl as someone she had to guide and protect. Which is what lead to her "betraying" Scarlett during that fateful mission.
• Phenotype Stereotype: She is blond, blue-eyed, and the American Hybrid Gear ace.
• Proper Lady : Played for Drama, a flashback in Volume 9 revealed that Yurishia's parents raised her to become one, ignoring what she actually wanted for herself and leaving her pretty dissatisfied with her life.
  "Since she was a child, beautiful and cute, a sweet image was demanded from her. Girlish, like a princess, become a lady, that was what was wanted from her."
• Rescue Romance: Starts falling for Kizuna after he risked his life to save her on their very first mission together.
• Rebuilt Pedestal: Turns out that the A-class enemy showing up in the place Yurishia sent the Masters to was just a sad coincidence. She was worried that Scarlett's missiles would hit the city if she missed her shots, so she lied by saying that the enemies had changed direction to ensure that Scarlett wouldn't have to take part of this battle. When she discovered that an A-class enemy really appeared there, she disobeyed orders to go rescue her teammates even though she was exhausted from taking an entire squad by herself. Scarlett can barely hold back her tears when she discovers this.
• Sex Slave: Her innermost desire is to be owned and sexually used by Kizuna for his pleasure. She gets her wish during their Ecstasy Climax session during the volume 13 epilogue chapter.
• Shoulder Cannon: The "Differential Frames" of her Hybrid Gear stand right above her shoulders, and they can act either as thrusters or as particle cannons.
• Tomboy: She was this in her childhood, preferring superhero comics over fairytales and liking to play shooting games. Her parents didn't approve, as they were trying to raise her to be a Proper Lady.

Hayuru Himekawa

Hayuru Himekawa

A member of both Amaterasu and the morals committee, Hayuru has a very harsh and strict personality. Her HHG is called 'Neros', another of the 'Ros' series. Her weapons are a Katana and 8 Attack Drones shaped like blades. Her Immoral Weapon is a huge double bladed sword called "Gladius".

---

• Absurdly Sharp Blade: Her Immoral Weapon named Gladius. The narration of the novels implies that it doesn't cut the enemy, the blade cuts space itself to bisect the target into two.
• A-Cup Angst: While Hayuru is not an A-Cup, she feels insecure about her bust size because both Aine and Yurishia are bigger than her.
• Alliterative Name: Hayuru Himekawa.
• Attack Drone: Hayuru's Hybrid Gear Neros has the unimaginatively named "Blades," which fly around and slice opponents to pieces.
• Beneath the Mask:
  • The command center's 'Love Room' projects each HHG's inner kink to make it easier for Kizuna to perform Climax Hybrid with them. In Hayuru's case, it reveals that she secretly has a catgirl cosplay fetish, which she hadn't been aware of.
  • Hayuru is also submissive during Climax Hybrid sessions and eventually becomes Kizuna's pet. A fact which sparks a minor rivalry between her and Yurishia, who prides herself on being Kizuna's sex slave. In volume 10, Yurishia openly wears a dog collar around her neck as proof that Kizuna owns her, which causes Hayuru to become jealous.
• BFS: Neros' Immoral Weapon is "Gladius", which is zweihander-type blade powerful enough to simultaneously split each of a Tri-Head's magitech dragon in two.
• Butt-Monkey: She becomes a literal example once Aine and the other Heart Gears find out that Hayryu gets off on anal sex and foreplay. They tease her by reminding her that she has no chance of winning the contest since she can't get pregnant "that way".
• Casual Kink: She secretly likes pretending to be a catgirl, complete with meowing and making cat paw gestures. The Love Room even gives her cat ears and a tail attached to anal beads to increase her body's sensitivity.
• Katanas Are Just Better: Neros is equipped with one. Fitting, as she's the Japanese ace.
• Kissing Under the Influence: Not kissing, but something to the same effect. During the climax of volume 7 Hayuru and Yurishia are seen intensely groping each other thanks to the aphrodisiac effect of Kizuna's Connective Hybrid with Aine and Grace. There isn't any other scene in the series that implies they are anything but straight.
• The Lancer: To Kizuna's The Hero during the second story arc. With both Aine and Yurishia disappeared, Hayuru becomes Kizuna's main partner in battle.
• Last-Name Basis: Notably, she is the only one among Kizuna's teammates that he doesn't call by the first name. This changes after she complains about it in Volume 8.
• Law of Chromatic Superiority: Kind of subverted. Hayuru has a red Heart Hybrid Gear and is introduced as "Japan's ace", but while she is indeed strong, the other girls are just as strong as her.
• Love Confession: She confesses her love to Kizuna in volume 10.
• My Greatest Failure: During the second invasion, Hayuru was escorting refugees bound for the Tokyo Mega Float when the magitech weapon "Tri-Head" attacked. The attack knocked Hayuru unconscious and caused the deaths of a lot of refugees, including a little girl that she had sworn to protect.
• Nice Job Breaking It, Hero: Her attempt at defeating Aldea and the Tri-Head by herself ends with her getting captured and the rest of Amaterasu having to perform a very risky operation to save her.
• Non-Indicative Name: No, her Heart Hybrid Gear has nothing to do with historical figures or with the color black, why do you ask?
• The Rival: As previously noted, she and Yurishia are both sexually submissive and wish to become Kizuna's pets. Except Yurishia one-ups her by openly wearing a dog collar as proof that she's Kizuna's possession.
• Sour Prude: Unfortunately for her, she lives in a world where most of the problems can be solved directly or indirectly by Deus Sex Machina.
• Tsundere: Towards Kizuna. At first she was a strong Type A but after getting closer to him she started showing him more of her kinder side and less of her harsher side.

Silvia Silkcut

Silvia Silkcut

A transfer student from Great Britain and Kizuna's direct subordinate. She is a candidate to become part of Amaterasu in the future. Her family was left behind in London when the AU invaded, so now she is training in Ataraxia to obtain a HHG and rescue her country. Kizuna eventually installs the final 'Ros' series core, 'Taros' within her.

---

• A-Cup Angst: In the final volume, she complains that the breasts of all the other girls in Kizuna's harem have gotten even bigger as they aged, but she looks exactly the same. He assures her that she is still beautiful.
• Alliterative Name: Silvia Silkcut.
• Badass Adorable: Once she gets her own HHG she quickly proves herself to be a even stronger fighter than the other members of Amaterasu, thanks to Kizuna's Eros allowing a new installation process that greatly raises the basic specs of a HHG.
• Beware the Nice Ones: Silvia is probably the nicest girl in the cast, but that doesn't mean she is a pushover in a fight. After all, her Heart Hybrid Gear is a Mini-Mecha that is just as powerful as it is big.
• Big Damn Heroes: Arrives in the battlefield for her first battle right on time to save Amaterasu from being crushed by Ragrus.
• Blue Blood: Silvia comes from a family of former nobles.
• Child Prodigy: The girl isn't even in high school yet and she is already one of the top candidates to become the next Hybrid Gear pilot in Ataraxia.
• The Cutie: She's essentially their equivalent of Chiyo Mihama: an adorable child prodigy whom Kizuna and the others fawn over. Which is why Kizuna often rewards her with pats on the head, or by ruffling her hair.
• Doomed Hometown: London was taken over by the army of the AU before the series started. Well, this actually happened with pretty much every country in the world, but Silvia is the only character that explicitly uses this trope as her motivation.
• Fille Fatale: Once she joins the harem, she does her best to seduce Kizuna and enjoys performing Heart Hybrid and Climax Hybrid. The other members of his harem realize they cannot underestimate this little girl.
• Little Miss Badass: Silvia is the living proof that being small does not mean being weak.
• Mini-Mecha: Silvia's Heart Hybrid Gear—Taros—can be considered as one.
• My God, What Have I Done?: How Silvia reacts when she discovers that the damage Ragrus received from their battle left her amnesiac. This is the final blow that convinces her, Yurishia and Hayuru that they are not living in a world of Black-and-White Morality.
• The Pollyanna: Her parents were still in London when the AU army invaded, and she has no way of knowing if they are safe. She still does her best to keep smiling every day and hopes to become a Hybrid Gear pilot so that she can personally save her homeland.
• Small Girl, Big Gun: More accurately, a small girl with a Mini-Mecha.
• Sixth Ranger: She officially joins Amaterasu only after they already went through many battles and become an united team.
• Supreme Chef: The meals she cooks for Kizuna are all delicious.
• Sympathy for the Devil: Ragrus proved herself to be a pretty horrible person when they fought, but Silvia still shed tears when she discovered the girl lost all of her memories.
• Third-Person Person: Silvia always refers to herself by name, rather than pronouns.
• Token Mini-Moe: She's the youngest member of Amateratsu and the only childlike character among a cast full of hotties.
• Verbal Tic: She always finishes her sentences with "Desu".

Ataraxia

Reiri Hida

Prinicipal/Commander Reiri Hida

Kizuna’s older sister. She is the Principal and Commander of Ataraxia. Reiri was the one who called Kizuna to Ataraxia after discovering the true power of his HHG. Unlike her younger brother, she knows very well the true nature of their mother, and absolutely hates her for abandoning Kizuna when he was a child.

---

• Age-Gap Romance: Reiri steadily grows fonder of her kid brother, Kizuna, until she finally falls for him. Her official character bio states that he's her (quote): "lover/younger brother". However, if the top brass were to find out, Reiri could very well be stripped of her rank and Kizuna would likely be expelled from the academy. Which is why Reiri begins using her authority to order Kizuna to take days off, so they can meet off-base to have sex without fear of being caught.
• Big Damn Heroes: She arrives in Odin's world right on time to save Aine and the other girls from being executed by Odin, announcing her arrival with a powerful kick in the goddess's back.
• Bigger Stick: Zecros is Heart Hybrid Gear made by Nayuta using all of her remaining power and knowledge as a goddess and Reiri's biological information as the premise. The result is a HHG that can't be used by anybody but Reiri and greatly surpasses the performance of all others HHG. To say that it compensates for Reiri's lack of battle experience is a huge understatement.
• Big Good: Kizuna is The Hero, but Reiri is the commander everybody defers to.
• Brother–Sister Incest: In Volume 5, Kizuna ends up doing Climax Hybrid with her because there's literally nobody else left. It happens again in volumes 8 and 10, and as each of those moments pass, it becomes increasingly obvious that Reiri has come to love Kizuna more than as a sibling. By the time of the Harem Hybrid, they have become so comfortable with doing sexual things with each other they only remember such a thing is supposed to be a taboo when their mother points out.
  • In the epilogue chapter of Volume 13 She uses her authority to summon Kizuna for Ecstasy Hybrids whenever he has free time. Due to this, It is said that she has the highest chance of being impregnated by Kizuna.
• The Captain: Of the battleship Ataraxia.
• The Chains of Commanding: It doesn't show very often because Reiri has plenty of self-control, but having to order her younger brother and the other girls into fights that could end in their deaths takes a toll of her mind.
• Coitus Uninterruptus: In the epilogue of Volume 13, she holds an audio conference while she's in the middle of an Ecstasy Hybrid, with Kizuna still inside her.
• Cool Big Sis: While her job as the Principal and Commander of Ataraxia keeps her from spending more time with Kizuna as much as she would want to, she still shows support when she can. She also hates her mother for abandoning them and ripping apart Kizuna's self worth.
• Extreme Libido: Reiri's libido is so strong that, by volume 13, she has unprotected sex with Kizuna on a daily basis, usually for hours at a time. She even takes time off just so they can bang, which causes Aine and the others to complain that Reiri is monopolizing Kizuna's free time, because he has a responsibility to them too.
• Heterosexual Life-Partners: Implied to be this with Kei.
• I Did What I Had to Do: She is aware that sending the girls to fight without telling them that they will die if their Hybrid Count reaches zero is a horrible thing to do, but they are the only ones that can change the tide of the battle against the AU, so she doesn’t have much of a choice.
• Irony: It's no secret that she really hates Nayuta and would not hesitate to kill her for all the terrible things she has done to her and her brother. In the finale, she ends up being the one to kill her in order to save the world. However by then she has already forgiven her and acknowledges Nayuta as her mother, making the deed very painful and ironic.
• I Want Grandkids: Inverted and Invoked, in volume 13 while performing Ecstasy Hybrid with Hida Kizuna, Reiri wants to get pregnant so their mother Nayuta can become a grandmother and in the next volume she's revealed to have become pregnant, ironically Grabel and Zelshione ended up bearing Kizuna's children before her.
• Making Love in All the Wrong Places: In the epilogue of Volume 13, she and Kizuna perform an Ecstasy Hybrid in the command center's conference room, while Reiri's holding an audio conference. The meeting lasts 'til she realizes she's about to cum and abruptly closes the comlink to prevent the other world leaders from hearing her. It takes several minutes for Reiri to catch her breath, before asking Kizuna to do it again. The narration adds they continued (quote): "well into the night".
• Mission Control: As the commander-in-chief of Ataraxia, she is responsible for coordinating Amaterasu during missions. Justified because she doesn't have any compatibility with Hybrid Gears and thus can't fight. Or so she thinks. Nayuta planned to install Eros Core in Reiri, but since her daughter didn't show any aptitude for it, she presumed Reiri didn't have any compatibility with Hybrid Gears Cores at all. In reality, the process failed because Eros is a Core exclusive for men. Alas, by the time Reiri discovers that she does have aptitude, there isn't any Core left in Ataraxia. Finally subverted in volume 10, when Nayuta builds a Core exclusively for Reiri, called Necros.
• Parental Neglect: Nayuta didn't flat-out abandon her like she did with Kizuna (as far as we know), but that doesn't mean Reiri had a better relationship with her mother.
• Parental Substitute: The closest thing to a parental figure Kizuna had after his mother kicked him out of her life. It's the main reason behind his Big Sister Worship.
• Property of Love: Inverted during the installation of Reiri's 'Ros core, Zecros. It merged with Kizuna by taking the shape of his penis, which he says is proof that it was made exclusively for her. Thus, Reiri interprets it as Kizuna declaring that his penis is for her alone. The narration explains that thought of it heightened her already peaked arousal, driving her into outright heat.
• Reasonable Authority Figure: Reiri refuses to allow personal feelings to get in the way of her mission, but she is never too harsh with her brother or his companions. She won't cut him any slack just because they are siblings, but she also will never give him a cruel order.
• Sex Goddess: She becomes Kizuna's Top Wife due to being the only one who's able to keep up with his libido and by being the first among Amateratsu to become pregnant for him.
• Strong Family Resemblance: She looks like a younger version of Nayuta Hida.
• Top Wife: Once the girls of Amateratsu begin regularly engaging in CH sessions with Kizuna, they come to an agreement that whichever of them is first to become pregnant with his child would be recognized as such. Though Aine is the one Kizuna gives his virginity to, Reiri is said to be the one who has the highest probability of being the first among them because of how often she and her brother have sex, due to her extreme attachment to him combined with her nigh insatiable libido. Nayuta is eventually proven correct as, by the final Volume, Reiri is now pregnant with their unborn child; making her the harem's top wife.
• Wingding Eyes: Exaggerated during the installation of her 'Ros core because it merged with her brother by taking the shape of his penis, while he was in child form. The sight of it (and being told it was made exclusively for her) caused Reiri to start drooling, with ♥ shaped eyes.

Kei Shikina

Kei Shikina

The supervisor of Nayuta Lab and the person in charge of Ataraxia’s technology. She helps Reiri coordinate Amaterasu's missions and oversees the construction of new equipment to help the HHG users.

---

• Child Prodigy: She was seen as this when she was younger, as she explains in volume 10.
• Heterosexual Life-Partners: Implied to have this kind of relationship with Reiri.
• Mission Control: Shares this position with Reiri.
• Older Than They Look: She is 24, but with her petite body, you would be forgiven for thinking she is younger than Kizuna.
• The Quiet One: So much that most of the time she doesn't even talk with people, she communicates through a synthetic voice created by computer when she types in her console. She does speak with her mouth when she is alone with Reiri, but even then her voice is barely above a whisper.
• The Stoic: Rarely shows emotions.
• Token Wholesome: Unlike most girls in the series, Kei has never done any form of Hybrid with Kizuna, and was only seen in a Fanservice illustration once. Pretty impressive, given the nature of the series. Double Subverted during the Harem Hybrid chapters in volume 12. At first Kei is the only girl in the mansion that is still clothed, but she is then forced to strip because the others might feel uncomfortable if she is the only one that isn't naked. But even then, she doesn't get any scene with Kizuna.

Momo Kurumizawa

Momo Kurumizawa

The engineering department's top student. Her department is tasked with the creation of new equipment and weapons to help Amaterasu.

---

• The Engineer: Her role in Ataraxia.
• Gadgeteer Genius: Creates several weapons of different types for Ataraxia. Too bad that as good as they are, they just don't compare to the Heart Hybrid Gears.
• I Call It "Vera": She likes to give names to the weapons she creates.
• Wrench Wench: Naturally, given her job.

Masters

Scarlett Fairchild

Captain Scarlett Fairchild

The captain of Masters, the HHG team of the West USA Mega Float. She was Yurishia's teammate and used to admire her, but an incident broke the friendship between them. Her HHG is called 'Ares', capable of producing attacks using a large number of missiles.

---

• Can't Catch Up: Her Hybrid Gear isn't part of the "-ros" series, and thus lacks an Immoral Weapon. Naturally, after her introductory arc is over, she never gets as many awesome moments as the members of Amaterasu do.
• Fiery Redhead: She can be very hotheaded sometimes.
• The Leader: Of Masters.
• Macross Missile Massacre: The entire point of her HHG. Deconstructed in her backstory, when Yurishia refused to let Scarlett fight in an urban area because of the very real possibility of her wave of missiles hitting the town and the people living in it.
• More Dakka: The main armament of her Heart Hybrid Gear, Ares, is a couple of missile units. After performing Connective Hybrid with Kizuna, the amount of missiles they can carry is exceptionally increased.
• Out of Focus: In her debuting volume she got as much focus as Yurishia did. She never got to be in the spotlight again, as she and the other Masters Can't Catch Up to Amaterasu and thus spend the rest of the series as the "support team".
• We Used to Be Friends: With Yurishia. With a bit of help from Kizuna, they become friends again.

Gertrude Baird

Gertrude Baird

A foul-mouthed but energetic member of Masters. Her HHG is called 'Sigura', and her weapons are a pair of pistol-shaped particle cannons.

---

• Affectionate Nickname: Kizuna call her simply "Ger-san".
• Ascended Extra: Like the other Masters except Scarlett, Gertrude initially didn't have much of a role in the plot besides adding more manpower to Ataraxia. She ends up getting a much more important role when all the other members of Amaterasu and Masters are captured, leaving only her and Kizuna in Ataraxia. By the end of the series she arguably became more prominent than Scarlett.
• Dual Wielding: With her two pistols.
• Guns Akimbo: She fights with two particle cannons shaped like pistols.
• Platonic Life-Partners: Starts developing this kind of relationship with Kizuna later in the series. When they have to do Climax Hybrid in volume 12, the narration notes that Kizuna is feeling particularly awkward because he can't see Gertrude as anything but a friend. No other girl in the series has gotten such a reaction from him.
• Sophisticated as Hell: A Japanese exclusive example. Gertrude uses polite language mixed with verb suffix indicating contempt, creating a really weird dissonance.
• Unlikely Hero: Who would have thought that Gertrude, who was clearly outmatched by every major enemy the good guys had to face, would be the one to deliver the finishing blow to a Physical God?

Others

After the West USA Mega Float and Tokyo Mega Float form an alliance to take back humanity's continental territory, Masters travel to Ataraxia to work together with Amaterasu. The names of the remaining 5 members are Sharon Cunningham, Brigit Arclight, Leila Howitt, Clementine Barrows and Henrietta Mackintosh.

---

• Flat Character: They all have exactly one personality trait. Their limited screen time really doesn't allow them to develop further.
• Forgotten Fallen Friend: Brigit is killed by Valdy at the end of volume 3. Volume 4 spends a couple of paragraphs to tell the reader how this affected her teammates. Volume 5 and onwards, nobody seems to remember her. Notably, the Enemy Mine situation of the later volumes means that Amaterasu and Masters are now working with her killer, and none of them seem to be bothered by it.
• Hero of Another Story: They presumably have gone through many hard battles before coming to Ataraxia.
• Killed Off for Real: So far Brigit is the only character in the novels to die for real.
• The Worf Effect: Their number one role in the plot is to hype the new opponents Amaterasu must defeat by getting their asses kicked by them.

Batlantis Empire

In General

• Anti-Villain: They invaded Earth/Lemuria because Genesis, the pillar that supports the heaven and earth in their world, is crumbling down and they need to steal lots of magic power to stop this.
• Human Aliens: They are humans who live in another dimension.
• Lady Land: All their males died out centuries ago, so they reproduce using Genesis. Zelshione's son with Kizuna becomes the first male to be born in centuries.
• Life Energy: They are stealing this energy from Earth to try to prevent the destruction of Genesis.
• Pride Before a Fall: When those Puny Earthlings start scoring wins against the strongest warriors of the Empire.
• Puny Earthlings: They care little for the people of Earth and are very quick to belittle them.
• Sorting Algorithm of Evil: After defeating hordes of Mooks, the heroes finally face a human opponent when Aldea, a member of the "Expeditionary Force", appears before then. After that, Aldea's superior Grabel joins the fight. After they are defeated, the Imperial Guard comes. Finally, the empress herself is confronted in the final volume of the first arc.
• Spell My Name With An S: "Batlantis" or "Vatlantis"? According to the title card of episode 5, it's the former.

Nayuta Hida

Nayuta Hida

Kizuna and Reiri's mother, as well as Aine's former guardian. She was once renowned as the Heart Hybrid Gear inventor but has "disappeared" for unknown reason. She reappears at the end of Volume 3, revealing that she has traveled to the AU and allied herself with the Batlantis Empire.

Nayuta is a Walking Spoiler, so read with caution. This is a double warning.

---

• Breaking the Fourth Wall: Volume 11 starts with her directly addressing the audience to explain why that volume is a Breather Episode.
• Broken Pedestal: To Kizuna (who once saw her as a loving mother), Kei (who admired her as a brilliant scientist) and Valdy (who viewed her as a mother figure and her own "savior").
• Can't Hold Her Liquor: Later on in the second half of the story. Upon becoming a Physical Goddess in the form of a little girl, Nayuta starts to take an interest in drinking. However, she gets drunk incredibly easily. One time she got so drunk, she almost ended up warping reality and screwed everyone over. The group eventually managed to catch her and pumped her stomach. Ever since that day she was banned from drinking.
• Disappears into Light: After she gets defeated by Kizuna. Subverted when it turns out she just went into hiding.
• Disc-One Final Boss: The last enemy the heroes have to face before ending the war between Lemuria and Batlantis, which was the main conflict of the series until that point. But the story is still far from over, as the arrival of the Deus ex Machina proves.
• Dissonant Serenity: Comes with the Lack of Empathy. Nayuta commits several horrible crimes with the most serene smile in her face.
• Enigmatic Minion: To the Batlantis Empire, mixed with The Friend Nobody Likes (except Valdy).
• Face of an Angel, Mind of a Demon: Nayuta has a very pretty face, emphasized by her being always cheerful, but she has the mind of a completely amoral Mad Scientist. Gets even worse once she de-ages herself, taking the appearance of a cute little girl.
  • Though is somewhat subverted later on. While she still treats others poorly and often for her own amusement, she never does anything dangerous to them. At best she's the The Friend No Body Likes with the exception of her son, at worst, she's a troll who gets off making life difficult for others on purpose, especially her daughter.
• Faking the Dead: It looked like she died after being defeated by Kizuna, but it's revealed in the following volume that she survived and went into hiding.
• Faux Affably Evil: Nayuta is always calm, serene and soft-spoken. None of that hides the fact that she is probably the single most depraved villain in the series.
  • Though this is subverted in the second half of the story. After returning to life as a Physical Goddess in the form of a child,she becomes the Big Good leading the group fighting against the Deus Ex Machina. Though everyone with the exception of her son has not forgiven her for what she did. As a Physical Goddess, she's a Troll who gets off making people's life miserable, especially her daughter. However, she no longer does anything dangerous or life threatening to them. Just putting them in incredibly embarassing situations or exposing their most embarassing secrets in front of the person they like and watching them cry. A huge improvement from the monster that she was as a human. Still far from a good person though.
• For Science!: Nayuta committed many horrible crimes due to scientific curiosity over the Heart Hybrid Gears. It doesn't matter if they are magic or technology, it caught her attention, so she will discover everything about it, regardless of how many puppies she must kick.
  Nayuta: "I won’t tolerate anything that I don’t know."
• Graceful Loser: Took her defeat by Kizuna's hand pretty well. Makes sense, given that she wasn't as dead as she looked.
• Irony: As a human being, Nayuta was completely amoral. Willing to do the most horrific things For Science!! Simply because she lacked any form of human emotion. As a Physical Goddess however, she develops emotions and a sense of maternal love for her children. Eventually these becomes the two reasons that led to her Heroic Sacrifice in the finale, as she finds herself unable to live with the guilt of all the horrors she had committed back when she was human, combined with her desire to protect her children.
• It Amused Me: Starting from the second half of the story. Nayuta becomes a troll who gets off bullying others and making life difficult for them. Especially her poor daughter. She even refuses to help the group fight the enemy unless they comply with her silly wishes. Such as dressing Reiri up as a bus driver and forcing her to drive her and Kizuna around, saying she won't help otherwise. To say that the group is annoyed and angered by her whims is putting it lightly.
  Reiri: Gu……tha, that’s right……if I didn’t do that, this hag, throwing tantrum saying she won’t cooperate with the reinstall! Are you a brat! Shit-!
• Lack of Empathy: In Nayuta's eyes, every life is equally expendable. She will help people when it's convenient for her research, but if killing someone is what will get her more data, she won't even blink while doing so. In a flashback, an unnamed girl was testing a HHG by flying over the ocean and noted her Hybrid Count was low so she should stop. Nayuta, wanting to see what happens if the count hits zero, took manual control of her and forced her to keep flying at maximum speed even as she begged her to stop. When this led to the girl's death, Nayuta simply thanked her for the data. She even says the only reason why she had children was to see if she would feel something, but she didn't. Subverted in the second half upon becoming a Goddess. She eventually starts to develop emotions and a human heart. This ultimately accumulates in one of the two reasons for her Heroic Sacrifice in the finale as she finds herself unable to live with the guilt of all the horrors she had commmited as a human.
  Reiri: "You……since you turned into that form...A human heart and emotions, were born inside you, weren’t they?
• Mad Scientist: Between her Lack of Empathy and the way she treats her children, she is definitely this.
• Manipulative Bitch: Successfully manipulates most of the cast into doing what she needs to achieve her goals. Reiri is particularly angry about that.
• Morally Ambiguous Doctorate: True to the spirit of this trope, she is a Mad Scientist with no moral standards whatsoever.
• Ms. Exposition: A good chunk of her dialogue in Volume 8 consists of exposition about the Deus ex Machina, The Multiverse, and the process of reinstallation of the Cores.
• Nominal Hero: Starting on Volume 8. She saves everybody's lives and then basically hijacks Reiri's role as the Big Good, but only because it will help her get the data she wants. She makes no attempts of redeeming herself for what she did, and the only reason Kizuna and the others accept to work with her in first place is because they understand that without Nayuta's help, they are doomed to be destroyed by the Deus ex Machina. She Took a Level in Kindness later, but only towards her children.
• No-Sell: After becoming a god, Nayuta has so much magic power that when Grace tries to use Harvest on her, she reaches the limit of energy her body can take before Nayuta is even bothered by her attack. The same thing happens later with the Deus ex Machina.
• Older Than They Look: After being reborn as a Physical God, she takes the appearance of a little girl.
• Parental Incest: The reinstallation of Kizuna's Eros requires him to do Climax Hybrid with Nayuta. She tries to argue that since she is not a human anymore, she isn't bound down by their rules, but her son is not convinced. And given how Nayuta never showed any moral standards before, it's unlikely she would have cared either way.
• Perpetual Smiler: Is hardly ever seen without a smile after her introduction. No matter who she screws over, no matter who she's hurting, the woman is always smiling.
• Pet the Dog: After Kizuna saves her life at the end of Volume 8, she caresses his hair while giving him a genuine smile. A small gesture, sure, but given how she treated him before…
• Physical Goddess: After deciphering the technology of Genesis, she uses it to recreate herself as a living being similar to the ones that created the world.
• Raise Him Right This Time: After she sacrifices herself, Thanatos possesses her body and loses her memories. Kizuna and Reiri name this new little girl Setsuna and adopt her as their little sister.
• Took a Level in Kindness: After spending some time in an Enemy Mine situation with her children, Nayuta finally managed to find some maternal love within her. She even uses all her remaining power as a goddess to build a HHG exclusively for Reiri, because even if they ultimately lose, it could help Reiri and Kizuna to survive. Fully cemented in volume 12 when she apologizes for everything she has done to her children.
• Walking Spoiler: It's difficult to talk about her character without mentioning a huge plot twist occuring in the series.

Grace Sinclavia

Emperor Grace Sinclavia

The current Empress of the Batlantis Empire and Aine's younger sister. Her Magitech Armor is 'Koros'. Its signature weapon is a large scythe, and it has a special ability called "Harvest", which enables Grace to suck the magical power of her foes and use it to replenish her own.

---

• A Child Shall Lead Them: She is already a teenager by the time we meet her, but she has been on the throne for quite a while.
• The Atoner: Volume 9 reveals that Grace believes she has the responsibility to improve the relationship between the two worlds as atonement for everything she did to Lemuria during the war.
• Berserk Button: Anything that reminds her of Kizuna will make her furious. At first.
• Cain and Abel: The Cain to Aine's Abel, before she has a change of heart.
• Curtains Match the Window: Both her hair and eyes are pink.
• Defeat Means Friendship: Kizuna and Aine had to beat the Yandere out of her before getting her to listen to what they had to say about stopping the war.
• Energy Absorption: Grace's Koros has an Immoral Weapon called Harvest that absorbs the magic power from the target.
• Fiery Redhead: Her hair is actually pink but it still counts as she has a very short temper, especially when it concerns Kizuna.
• God Save Us from the Queen!: Has no mercy to the enemies of the Batlantis Empire. Regardless if you are part of the empire, it's still not a good idea to get on her bad side.
• Grade Skipper: She is Kizuna's classmate in the Lighter and Softer fake world Nayuta created, despite being two years younger than him.
• Improbable Age: Due to the death of the previous empress and the disappearance of the first princess, Grace was enthroned before her age reached the double digits.
• I Want My Beloved to Be Happy: Despite her own feelings for Kizuna, she allows Aine to be with him when the worlds are separated.
• Last Episode, New Character: She appears at the end of episode 12.
• Love Father, Love Son: Just like everyone else, she eventually falls in love with Kizuna. When the worlds are separated, she decides to settle for his son with Zelshione when he comes of age, reasoning that a 15 year age difference won't be unusual.
• My Sister Is Off-Limits: She hates Kizuna for taking away her sister Aine from her, referring to him as "Demon King of Lemuria".
• Names to Run Away from Really Fast: Her Magitech Armor Koros is a homophone for "Kill" in japanese.
• Odd Name Out: The only character born in Batlantis with a normal-sounding name.
• Only One Name: She and her sister are the only characters born in Batlantis to avert this trope.
• Please, Don't Leave Me: Understandable, since her sister disappeared out of nowhere when she was still a child, leaving Grace with no family for years. Still, it's impossible to deny that her almost pathological fear of being abandoned by her sister again has left some truly ugly mental scars on her.
• Royals Who Actually Do Something: Sees nothing wrong in joining the battlefield personally, much to Zelshione's displeasure.
• Sanity Slippage: A pretty bad one in Volume 7, as her emotional issues reach their peak. She gets better at the end.
• Sibling Incest: She quickly makes it clear that her feelings for Aine go beyond sisterly love. After her Heel–Face Turn their relationship changes into a more normal sisterhood, which implies her incestuous feelings were caused by her Sanity Slippage.
• Sinister Scythe: Her main weapon is a scythe that transforms from the wings of her Magitech Armor.
• Superpower Lottery: Normally, using an Immoral Weapon would consume magic power drastically, but since Harvest absorbs magic power from the enemy, Grace will never run out of energy while fighting.
• Troubling Unchildlike Behaviour: Having to assume the role of empress from a very young age due to the absence of her older sister clearly did a number to her psyche.
• Used to Be a Sweet Kid: She was once a kind girl, but everything went From Bad to Worse when Aine disappeared.
• Walking Spoiler: It's impossible to discuss anything about her without revealing that Aine is actually a princess from the Batlantis Empire, and is Grace's older sister.
• The Worf Effect: What better way to establish that the new villains are a threat than having them No-Sell the attacks of a Superpower Lottery Winner?
• Yandere: For her sister Aine. She tries to get Kizuna killed so that Aine's heart can "return to Batlantis", and when she gets the impression that her sister choose Kizuna over her, she tries to kill both of them personally. She gets better.

Grabel

General Grabel

A powerful general from the Batlantis Empire and commander of the 6th expeditionary force of Lemuria district. She actually comes from Izgard, one of the many countries conquered by the empire. The people of the empire see Grabel as a hero for her bravery in battle, but the Imperial Guard is distrustful of her. Her Magitech Armor is 'Zoros' and her Immoral Weapon is called Sword Gatling.

---

• Anti-Villain: Type I. Grabel may be ruthless in battle, but she never does anything unnecessarily cruel to her enemies, despises the idea of killing civilians, and treats her partner Aldea well, despite her Blood Knight tendencies.
• Babies Ever After: Has a daughter with Kizuna.
• Defector from Decadence: She always hated how the Imperial Guard had no respect to their enemies, to the point of withholding important info from them just to get the chance to finish the battle with Ataraxia without unnecessary causalities on their side. And just as she feared, the first order Zelshione gives when she found out that Zeros is in Lemuria is "kill 'em all". But that's not her only reason for defecting...
• Dodge the Bullet: She dodges a sniper shot with minimal movement when she first arrives at Ataraxia. Cue Mass "Oh, Crap!".
• Everyone Has Standards: Grabel is utterly ruthless when fighting, but even she thinks that completely slaughtering the enemy, civilians included, is crossing the line.
• Frontline General: In spades. After discovering Zeros was in Ataraxia she does not hesitate for even a second before launching an attack personally.
• Gatling Good: Her Immoral Weapon is a huge sword with a gatling gun attached to it.
• Happily Married: To Aldea, following the events of the war against the Deus Ex Machina. According to Grabel's bio, they now live together as wife and wife and are raising Grabel's daughter.
• Heroic Willpower: Zelshione notes that she is normally able to turn people into mindless love slaves instantly, but not her. Her hypnosis works, as she can take control of Grabel's senses, but she does not break even after being tortured for two weeks.
• I Am Not Pretty: She has the combination of this and No Guys Wants An Amazon to Kizuna at first.
• Mistreatment-Induced Betrayal: She never liked the imperial guard in first place, but after being accused of treason for not reporting that she found Zeros and then tortured by Zelshione, Grabel abandons the Batlantis Empire in the first opportunity.
• Official Couple: She weds Aldea in the year following the war against the Deus Ex Machina.
• One-Night-Stand Pregnancy: Invoked she slept with Kizuna to get pregnant with his child, knowing she could never see him again and to have a lifetime with their child.
• One-Woman Army: With a dose of Asskicking Leads to Leadership for good measure.
• Only Sane Man: Plays this role for the Batlantis Empire, as she lacks both Aldea's Blood Knight tendencies and the smugness and overconfidence of the imperial guard.
• Punch-Clock Villain: At the end of the day, she is just a soldier fighting for her country.
• Rebel Leader: Eventually becomes this for the rebels in Izgard that don't accept that their country has been absorbed by the Batlantis Empire.
• Red Oni, Blue Oni: The blue to Aldea's red.
• Sacrificed Basic Skill for Awesome Training: She was indeed very good when it comes to combat-related skill, but she was also very awkward with non-combat-related one.
• Screw This, I'm Outta Here: Decides to bail from the Batlantis Empire after being accused of treason.
• Smash Sisters: With Aldea. Well, she is technically Aldea's superior, but she treats her as an equal and doesn't really exercise her authority unless Aldea's lust for battle gets out of hand.
• Someone to Remember Him By: She sleeps with Kizuna during the final volume of the LN, after realizing their worlds would be permanently sealed off from one another. It results in Grabel becoming pregnant and eventually gives birth to their daughter.
• Throwing Down the Gauntlet: What her first visit to Ataraxia amounts to. Having found out where Zeros is, she goes to challenge the enemy forces alone and delivers a completely ruthless Curb-Stomp Battle.
• Underboobs: Prominently shown in her "uniform".
• Villainous Friendship: With Aldea, through it’s more like "Anti-Villainous Friendship". As in, friendship with benefits.
• Would Not Shoot a Civilian: When Grabel first arrives in Ataraxia she makes a point of asking if there are any non-combatants on board. The answer she gets is that everybody living in Ataraxia is directly or indirectly related to the defense of the Megafloat, which is an answer that allows her to go all out.
• You Are in Command Now: After leaving Batlantis, Grabel comes back to her country Izgard, and is entrusted with the chain of command temporarily as an emergency measure during war times. She uses her new authority to create an alliance with Ataraxia.

Aldea

Aldea

A member of the 6th expeditionary force and Grabel's partner, as well as the first human antagonist in the series. Unlike Grabel, Aldea loves battling and has a sadistic streak. Nonetheless, she is very loyal to her friend. Her Magitech Armor is called 'Zeel'. It has an ability to change the form of its weapon from a shield to a spear.

---

• Attack Drone: Her Magitech Armor has these. They can act as protective shields or transform into a spear.
• Blood Knight: She really enjoys fighting against strong opponents.
• Blood-Splattered Warrior: Midway through Volume 7, Aldea comes back from a brief off-screen battle covered in blood. She seems pretty pleased about it.
  Aldea: "Hehehe, isn't it fine? Half of this is the opponent's blood."
• Bunny-Ears Lawyer: Turns out that she came from a noble family and used to be part of the imperial guard. She wasn't very popular because of her extreme lust for battle, but the fact that Grabel immediately identified who she was during their first meeting and their battle could have ended with either of them dying shows that she was very good in her job. Subverted because she eventually did get demoted for her… eccentricity.
• Clingy Jealous Girl: She really didn't like to see Kizuna and Grabel getting closer to each other.
• Friends with Benefits: First seen when she initiates foreplay with Grabel in bed, but Aldea's forced to stop before they can actually have sex, due to an emergency dispatch order via the intercom.
• Happily Married: She officially weds Grabel sometime after the war with the Deus Ex Machina and helps raise Grabel's daughter.
• Human Pet: For perceived treason, Zelshione brainwashes her into acting like her dog, complete with a collar and leash.
• Interplay of Sex and Violence: Not that she has anything against sex without violence, mind you, but her Blood Knight tendencies are sometimes taken to a… disturbing level. Like in the Special Short Story of volume 11, where she hugs Grabel and gives her a loving, intense look as she talks about how much she wants to have a death match with her. The narration even notes that "Killing each other or an act of love, any of the two could possibly happen after this".
• Mistreatment-Induced Betrayal: Like Grabel, Aldea was more than ready to defect from the Batlantis Empire after Zelshione brainwashed her into becoming a mindless servant and tortured Grabel for information.
• No Sense of Personal Space: When it comes to Grabel. She is much clingier than her partner is comfortable with.
• Number Two: To Grabel, at least on paper.
• Psycho Lesbian: Averted. While her extreme Blood Knight tendencies make her look totally psychotic sometimes, her love for Grabel is portrayed as a redeeming quality. In fact, it is the first sign the audience receives that this Blood Knight isn't completely evil.
• Red Baron: Turns out she had many lovely nicknames back when she was still part of the Imperial Guard. The Green of Madness; Ally Killer; Battle junkie in the form of a lady; Shield of Madness of the Imperial Guard…
• Red Oni, Blue Oni: The red to Grabel's blue.
• Relationship Upgrade: Starts off as Grabel's subordinate/lover and eventually becomes her wife.
• Screw This, I'm Outta Here: She decides to bail out of the Batlantis Empire along with Grabel.
• Shout-Out: Her Attack Drones can be assembled in a geometrical shape to create a barrier that can be used either for defense or to trap enemies within, just like the Nu Gundam.
• Smash Sisters: She often fights alongside Grabel. She is actually supposed to be Grabel's Number Two, but the two of them act more like companions on equal ground.
• Spell My Name With An S: Her Magitech Armor is either Zeel or Zeeru.
• Starter Villain: The first human antagonist Amaterasu has to fight.
• Token Evil Teammate: She is not really evil, but she is a psychotic Blood Knight who never really grows into someone more heroic, not even during the Enemy Mine situation in the later volumes.
• Villainous Friendship: She has a Friends with Benefits relationship with Grabel, but even if you ignore the sexual aspect of it, there is clear camaraderie and trust when they fight together.

Ragrus

Ragrus

An elite soldier of the Batlantis Empire and a member of the Imperial Guard. Ragrus is very overconfident of her own abilities and has a haughty attitude towards anyone she deems inferior to her. She possesses a huge Magitech Armor called 'Demon'.

---

• Amnesiac Dissonance: Ragrus is introduced as a haughty Smug Snake who thinks that the earthlings are bugs for her to squash and tries to Rage Quit after losing a fight. After Laser-Guided Amnesia hits her, Ragrus is a meek little girl who becomes one of the biggest fans of Amaterasu.
• Badass Arm-Fold: She and Demon do this at the same time when she presents herself to Amaterasu.
• Defeat Means Friendship: More complicated than most examples. After being defeated by Silvia she got hit by Laser-Guided Amnesia and ended up becoming a fan of Amaterasu as an Idol Singer group. Then she was taken to the fake world Nayuta created and had fake memories implanted on her that made her and Silvia believe they were normal classmates. When they finally got their real memories back they were already best friends, though Ragrus refuses to admit it out loud.
• Evil Counterpart: To Silvia. They are the Token Mini-Moe of their respective sides, they both want to impress their superiors (Kizuna and Zelshione) and them both have a Mini-Mecha for a Heart Hybrid Gear. Their personalities, however, are like night and day. Subverted later when they become friends.
• Hair-Trigger Temper: It doesn't take much to piss her off.
• I Choose to Stay: When the portal between the the worlds is about to close forever, she decides to resign and remain in Lemuria to be with Silvia.
• Laser-Guided Amnesia: Ragrus lost all of her magic power after her battle with Silvia, and as a result she lost her memories.
• Mini-Mecha: Her Magitech Armor called Demon.
• Ojou Ringlets: We don't know her social status, but she has these.
• Rage Quit: Tries to pull a Taking You with Me after losing to Silvia, who manages to stop it on time. Good thing too, because Ragrus was perfectly willing to take everything with her, even if her allies and innocent people were within the blast radius.
• Small Girl, Big Gun: Ragrus is a small girl. Demon is a Mini-Mecha that towers over the cast.
• Sore Loser: Trying to destroy everything and everyone around her after losing a battle is the biggest proof she could give that she is one of those.
• Spell My Name With An S: It's either "Ragrus" or "Ragres".
• Token Mini-Moe: The youngest character from the Batlantis Empire, contrasting with Silvia.
• Tsundere: After recovering her memories and coming to Ataraxia, Ragrus spends most of her time with Silvia. Whenever someone comments on their friendship she furiously denies being friends with her, but nobody is fooled.
• Villainous Breakdown: When Silvia starts overpowering her during their fight, Ragrus completely loses it.

Valdy

Valdy

A member of the Batlantis Empire's Imperial Guard and an expert of covert operation. She is assigned as the watcher and bodyguard of Nayuta and quickly develops a strong admiration for the woman. She has a Magitech Armor called 'Rael'.

---

• Beware the Quiet Ones: The biggest Shrinking Violet in the cast is also the only Hero Killer.
• Conveniently an Orphan: It's the reason she is so desperate to find a Parental Substitute. And that certainly was very convenient for the Manipulative Bitch she was assigned to watch.
• Does Not Like Men: She can't deal with men, to the point Kizuna has to cross-dress to do Climax Hybrid with her.
• Fashionable Asymmetry: When equipped with Rael.
• I Choose to Stay: When the portal between the the worlds is about to close forever, she decides to resign and remain in Lemuria to be Reiri's bodyguard.
• Horrible Judge of Character: OK Valdy, we understand that you have issues, but did you honestly believe Nayuta was interested in saving Batlantis?
• Invisibility Cloak: One of the abilities of her Magitech Armor. She can even bring another person with her under it.
• Parental Substitute: Finding one is her dream. Unfortunately, she thought Nayuta could be the mother she always wanted. She later starts seeing Reiri as her new mother figure.
• Psycho Lesbian: Unlike other characters from Batlantis, Valdy cannot deal with men even after spending some time in the fake Ataraxia Nayuta created. As for the "psycho", volume 10 confirmed that she has a few screws loose, to say the least.
• Shrinking Violet: Extremely shy and introvert.
• Spell My Name With An S: "Valdy" or "Varde"?
• Undying Loyalty: To Nayuta. After being betrayed by her, she instead decides to dedicate her loyalty to Reiri and Kizuna.
• Yandere: Seemingly goes through a Sanity Slippage during her Climax Hybrid scene in volume 10 as Kizuna’s appearance awakens her secret desires. The boy tried to help after realizing that Valdy's view of love is really unhealthy, but in the end he couldn't do much.
  "Many times, I saw a dream. I desired……a mother only for me, a princess only for me. My yearning…… is to kidnap, and take her to a secret place that only I know."

Zelshione

Captain Zelshione

Captain of the Batlantis Empire's Imperial Guard and Grace's aide. She is completely loyal to the empire and the royal family, but has no mercy against those she perceives as enemies. Her Magitech Armor 'Teros' has several different abilities to Mind Rape her foes. She can read minds, manipulate the senses of the target, create illusions and even mind control people into becoming her slaves.

---

• Affectionate Nickname: Grace calls her "Zel", while the Quartum use the more respectful "Zel-sama". Aine also calls her "Zel".
• Babies Ever After: Has a son with Kizuna by the epilogue, making her the first woman to bear his child, unless Grabel gave birth first.
• Bad Boss: Members of the expeditionary force (that apparently is inferior to the imperial guard in the hierarchy of Batlantis) like Aldea and Grabel really shouldn't expect kindness from her.
• Beat Them at Their Own Game: Mixed with Did You Just Punch Out Cthulhu?. Osiris is a Physical God that likes to defeat her opponents by Mind Raping them. Zelshione proves she has taken a level in Badass thanks to her reinstalling Teros with Kizuna's help by Mind Raping her.
• Benevolent Boss: Contrasting with the way she treats the expeditionary force, she's actually a fairly good leader for the imperial guards under her direct command.
• The Baroness: This series is filled to the brim with attractive female villains, but Zelshione is the one that best matches this archetype.
• Bond Villain Stupidity: If she had actually tried to kill Kizuna herself instead of making a hypnotized Aine do it, the Batlantis Empire would have won.
• Curtains Match the Window: Both her hair and eyes are purple.
• Does Not Like Men: She claims to not have any interest in men. Given the context, it's unclear if that was just her going Tsundere over Kizuna or if she really means it and the boy proved to be a case of If It's You, It's Okay.
• The Dragon: As the captain of the imperial guard, she is this to Grace.
• Even Evil Has Loved Ones: Zelshione is by no means a nice person, but her Undying Loyalty to the royal family is genuine, just like the affection she has for the Quartum.
• Kick the Dog: She could have killed Kizuna herself, but instead she ordered his hypnotized teammates to do the job For the Evulz.
• Mama Bear: When Quartum shows up to arrest her for going AWOL, she attempts to fight them even without her armor, thinking they would take her son away. When she and her son are brought before Grace, she begs them not to hurt him. Fortunately, they had no intention of doing that.
• Mind Rape: The main power of her Magitech Armor Teros.
• Power Perversion Potential: Her "torture" sessions consist of whipping the victim while using her Mind Rape power to make their bodies register the pain as pleasure. As Grabel found out the hard way, this is really efficient.
• Praetorian Guard: The imperial guard under her command.
• Purple Is Powerful: She is the captain of the imperial guard for a good reason.
• Sociopathic Soldier: A borderline Type I when first introduced. Thankfully she gets better later.
• Student Council President: In a move that borders on Refuge in Audacity, Nayuta made her the Student Council President of Ataraxia in her fake world. Never mind that she is way past high school age. It quickly became an in-universe Old Shame when Zelshione got her memories back.
• Tempting Fate: When she and Kizuna have sex for the last time before the worlds are separated, even though she already experienced how mind-blowingly amazing sex with him is, she bets that she'll have him so lost in pleasure that she'll dominate him and he'll be on his hands and knees begging for more. Thirty minutes later, he is dominating her and she is on her hands and knees begging for more. She admits she underestimated him once again.
• Took a Level in Kindness: Kizuna and Grabel both note that after spending some time in the fake Ataraxia Nayuta created, Zelshione became more amicable.
• Tsundere: Type I towards Kizuna after the events of Volume 9.
• Undying Loyalty: To the members of the royal family, Grace and Aine.
• Unishment: She has an affair with Empress Aine's lover Kizuna and then goes AWOL to raise her son in peace. She is eventually found and arrested, and Grace points out she committed two counts of treason and must be punished. So... Grace fires her, confiscates her weapons, and sentences her to house arrest in the palace until she raises her son into a splendid person. She is moved to tears by Grace's generosity.
• Whip of Dominance: She is the sadistic, domineering, and haughty captain of the Atlantis Imperial Guard and her primary weapon is a Whip Sword that can morph between whip and sword mode. She delights in personally pushing her own men and other prisoners, often with her own whip. And when she really wants to break someone she uses her Hypnotic Eyes on the prisoners that force their bodies to register pain as pleasure, then she'll mercilessly whip them until they become her submissive "pets".
• Whip Sword: Her main weapon is a whip that can turn into a sword.

Quartum

Quartum

Four female warriors of Batlantis who serve under the direct command of Zelshione as her close aides. Their names are Clayda, Elma, Lunorlla and Ramza. All four of them were handpicked by Zelshione after witnessing their impressive performances at the Colosseum.

---

• Always Accurate Attack: Elma's weapon, called 'Lunir's hammer', changes the stream of cause and effect to send the target flying before the hammer actually hits, which in practice means that she will never miss.
• Covered in Scars: Lunorlla has scars all over her body.
• Dissonant Serenity: Not as bad as Nayuta, but Elma keeps her gentle smile even when she is bashing Kizuna with a giant hammer.
• Dual Wielding: Lunorlla is a two sword style user.
• Elite Four: The narration even calls them "Shitennou" at least once.
• Eyepatch of Power: Clayda wears one over her right eye. In Volume 14, she flips it to reveal an artificial eye that makes her immune to Zelshione's mental powers.
• Genki Girl: Ramza, contrasting with Lunorlla’s Shrinking Violet.
• Playing with Fire: Ramza's power.
• Power Incontinence: Ramza can't properly control her powers, which is why she was abandoned by her parents. It also caused her to accidentally burn the facility she was held in to the ground.
• Quirky Miniboss Squad: The four of them are much stronger than the Elite Mooks, but they are still not on the same level as Grace or Zelshione, and they all have distinct personalities.
• Recruited from the Gutter: Lunorlla was living as a beggar when the organizer of the Colosseum picked her to play the role of "the killed one" in an opening match. Instead she won the fight and went on to become one of the best fighters in Batlantis.
• Red Baron: Lunorlla is known as "The God of Death of the Colosseum".
• Shrinking Violet: Lunorlla is so shy she can't even speak to a large crowd. Kizuna mentally compares her to a child with stage fright.
• Street Urchin: Lunorlla used to be one.
• Those Two Girls: Ramza and Lunorlla are always together.
• Undying Loyalty: All of them to Zelshione.
• Unexplained Recovery: Clayda gets shot by an overloaded magic gun at point-blank range and thrown at the sea. Elma is hit by a particle cannon meant to destroy battleships. Zelshione later refers to them as MIA, confirming that the empire didn't rescue them after their defeats. Three volumes later, they are back to Zelshione's side, with no explanation given for how they survived.

Deus Ex Machina

Warning: Everything about these characters is a spoiler for events beyond volume 7.

In General

• Big Bad Ensemble: After the war between the worlds is over they appear and become the main threat to the entire cast, as the creation of the worlds was just an experiment for them and they have decided that it was a failure, thus both worlds must be destroyed and their "data" retrieved. At first they seemed to be a Big Bad Duumvirate but they don't actually work together when it's not necessary and each of them has their own agenda.
• Evolutionary Levels: They were born as humans, but thanks to extensive research of magic, technology and Magitek in their respective worlds, they evolved into beings so powerful they could be called Gods. Thanatos is the single exception, as she was created to be a goddess.
• No-Sell: If your HHG has not gone through the Next Tier Power-Up, your attacks are not going to reach them.
• Outside-Context Problem: Despite all the Magitek weaponry present in the series, absolutely nobody predicted that it was possible to use magic and technology to ascend a human to the same level of a Physical God. With the exception of Nayuta, absolutely nobody predicted their appearance.
• Physical God: Being powerful enough to create entire worlds and basically immortal, it is really hard to argue that they are indeed goddesses.

Hokuto

Hokuto

A goddess with a teenage body and an immature personality, she is the first Deus Ex Machina the heroes face in battle.

---

• Lonely at the Top: Her people made her evolve into a goddess so at least she could survive the end of their world. Unfortunately, this means she must live alone in the new world she created, and she is not happy about it, no matter how powerful she has become.
• Stepford Smiler: She is always smiling, either when she is mocking the inferior humans or just hanging out in her own world. This is only because she believes that if she isn’t happy with her godhood, her people who have sacrificed themselves to make her immortal will have died for nothing.

Osiris

Osiris

One of the four goddesses of Deus Ex Machina and the ruler of the dead city Necropolis.

---

• The Heavy: She messed with the experiment behind the backs of the other goddesses for her own purposes, which is what led to the creation of Lemuria and Batlantis. If it wasn’t for her, those worlds wouldn’t exist as they do, making her singlehanded responsible for the plot of the series happening.
• Sanity Slippage: Having to slowly observe her world crumbling apart, losing her husband and daughter, and them spending millennia alone has completely twisted her psyche. She gets better thanks to Kizuna.

Odin

Odin

A goddess ruling over an icy world, who indulges in fighting strong opponents.

---

• Blood Knight: Even more than Aldea. As far as she is concerned, fighting and getting stronger is the meaning of life.
• The Social Darwinist: If you are weak, you die. If you are strong, you must fight other strong people so you can get even stronger. For Odin this isn’t her personal opinion, it’s how the world works.

Thanatos

Thanatos

One of the four goddesses of Deus Ex Machina. She is also its leader and the strongest of them all.

---

• Desperately Looking for a Purpose in Life: Unlike the other three goddesses, she has no idea what to do with her god-like powers, because she doesn’t see any meaning in her own life. She is already the strongest being in the universe, what else is there for her?
• Final Boss: Of the series as a whole. She is last opponent the good guys must defeat.
• Raise Him Right This Time: After Nayuta sacrifices herself, she possesses her body and loses her memories. Kizuna and Reiri name this new little girl Setsuna and adopt her as their little sister.

---
