    Main Characters 

Inaho "Nao" Kaizuka

Voiced by: Natsuki Hanae

An ordinary Earth boy who has an amazing ability to remain calm in dangerous situations. He winds up thrown into the center of the conflict when the civilian caravan he's helping to escape picks up both a girl who knows the truth about the princess's assassination, and the princess herself.
  • Action Survivor: Survives not only the missile attack on Princess Asseylum's convoy (while he wasn't targeted, he was close enough to have gotten hit by an explosion or debris), but also a close encounter with a Kataphrakt.
  • Awesomeness by Analysis: He quickly figures out an enemy Kataphrakt's abilities and limitations by simple observation and then reviewing video footage.
  • Child Prodigy: His tactical and observational skills allow him and a small group of friends to defeat one of the Maritan Kataphrackts, something that none of earth's military could manage.
  • Combat Pragmatist: His strategic skills manage to get his group away from an attacking Kataphrakt.
  • Genre Savvy: He is able to figure out how to exploit the Kataphrakt's weaknesses simply from observing it in action for a short while, along with viewing some video footage of it. And in episode 2, while being pursued by Trillram with Yuki's mech stuck on their APC, he tells Inko to slam on the brakes. While it seems counterintuitive at first, Triilram's mech inadvertently helped by atomizing the lower part of Yuki's mech, thereby lightening their load and allowing them to drive a little faster.
  • Nerves of Steel: Seeing a missile aiming to kill the Martian princess did not faze him at all.
  • Parental Abandonment: He lives with his older sister and their parents are nowhere to be found.
  • Skewed Priorities: He was more interested in the sale on eggs going on than watching the VERS princess as her convoy drove by, and later when it's attacked.
  • The Stoic: He's completely unfazed by witnessing the death of one of his best friends. Though he appears to be shocked momentarily, it only lasts for a few seconds before he's back to his calm self.
  • Tranquil Fury: He seems eerily calm considering all the death and destruction going on around him.

Slaine Troyard

Voiced by: Kensho Ono

A young boy who tutors the princess about Earth. He knows so much about it because he was born there. Official material reveals that he and his father defected to Mars about five years prior to the story's beginning.
  • Apologetic Attacker
  • Beware the Nice Ones: Trillram should not have underestimated him and his dedication to the Princess.
  • Conflicting Loyalty: He's loyal to the Vers family, but he hesitates he's facing Terrans because he's one of them.
  • The Dog Bites Back: He takes a lot of verbal abuse from Trillram in episode 2 for his hesitation to kill. In the next episode, after Trillram angrily snaps at him to come with him to kill the princess and insults him again, he snatches Trillram's service pistol out of its holster and guns him down on the spot.
  • Even Evil Has Standards: While he doesn't object to the VERS Empire invading Earth, he doesn't take it too well when he learns Princess Asseylum was killed, only to later be found alive. And Trillram wanted her dead to conceal the justification for their invasion.
  • Extreme Doormat: He lets people constantly abuse and mock him for his heritage as an earthling, and even participates in the invasion of earth despite wanting peace. The former is a bit distressing because he's very close to the princess, someone with the authority and reason to stop any bullying he may face.
  • Foil: According to his profile, he's this to Inaho. While one controls his emotion and is logical, Slaine is meant to be emotional and intuitive.
  • Going Native: Tries to in Mars, as an immigrant from Earth.
  • The Heart: One of his character descriptions in the official website, as the most kindhearted character at core of the show.
  • Heel-Face Turn: Once he finds out about the plot to kill Princess Asseylum, he kills Trillram on the spot.
  • Nice Guy: Being a "good person/boy/child" is the basis of his personality.
  • Wide-Eyed Idealist: Asseylum carries his and his father's prayers of peace.

Asseylum Vers Allusia

Voiced by: Sora Amamiya

The princess of the Vers empire, who does not subscribe to her religion's belief that Terrans are inferior primitives. Instead, she pushes for peace between the two, but unknowingly becomes the catalyst for a new interplanetary war.
  • Action Survivor: Killed in the first episode by a missile strike from a terrorist group. Except it was a body double, and the real princess was hiding as a tourist when the fighting breaks out.
  • Badass Princess: She's perfectly capable of flipping and body pressing someone her size or bigger with little effort.
    • Cemented in Episode 3 in which she volunteers to be the standing gunner in the counteroffensive against Trillram and manages to not only expertly handle a grenade launcher in her first experience with live combat, but also buys the group the time they need by singlehandedly driving Trillram back with sheer force of will and charisma.
    • Badass Adorable: Despite her cute appearance, there is no denying the fact that she's a competent fighter herself.
  • Green Eyes
  • King Incognito: After the war starts she pretends to be an ordinary tourist caught in the wrong place at the wrong time.
  • Not Quite Dead: Episode one lead us to believe she was assassinated by high-ranking members of the Martian government to get an excuse for a war, but it turned out to be a body double. She'd fallen ill because of the change in gravity.
  • Rapunzel Hair: It's very long. After the assassination attempt, she uses Martian technology to hide its true length and color.
  • Transformation Sequence: She does one in episode 3 to reveal she's still quite alive to Trillram to buy Inaho some time for his plan.

    Earth Federation Army 

Inko Amifumi

Voiced by: Mikako Komatsu

The local Student Council President, she is a cheerful girl who quickly takes charge of a group of evacuating refugees when the war begins.
  • Chekhov's Skill: One of the first things we see her doing is Kataphrakt training on a heavy anti-materiel sniper rifle. This rifle is used to destroy the section of the bridge the Nilokeras is standing on in episode 3.
  • Childhood Friends: With Inaho.
  • Drives Like Crazy: Though it was kind of forced on her due to the APC she was in being pursued by Trillram.
  • Student Council President: She tries to order Inaho and some of the other boys to help them out with the parade for Princess Asseylem after finding out they're very short-staffed for the event.

Calm Craftman

Voiced by: Taishi Murata

A student from the Shinawara high school. He's a foreigner who notes that Japan is in a lot better shape than the country he came from.

Nina Klein

Voiced by: Ai Kakuma

Another student at Shinawara high school, she is also a foreigner and from the same country as Calm.

Okisuke "Okojo" Mikuni

Voiced by: Yoshitaka Yamaya

A friendly joker who everyone likes, although he doesn't seem to be doing too well grade-wise in his courses.
  • Keet: Upbeat and enthusiastic in everything he does.
  • Sacrificial Lamb: The first named character to die in the series.
  • We Hardly Knew Ye: He literally disappears pretty quickly from the story, due to getting atomized when he loses grip of Inaho's hand and falls towards the pursuing Trillram's mech.

Warrant Officer Yuki Kaizuka

Voiced by: Sayaka Ohara

Inaho's older sister and a Warrant Officer in the UE Army. She serves in 2nd Lt. Marito's platoon and is also an instructor for the students during their Kataphrakt training courses.
  • Adult Fear: She truly worries about Inaho being thrown into actual combat, knowing he could be killed anytime.
  • Promotion to Parent: For Inaho, considering their real parents aren't around, and she fusses and worries about his well-being constantly.
  • Reasonable Authority Figure: She allows a surprisingly amount of freedom to her students, and later while she tries to stop Inaho from attacking Trillram, she ends up letting him do it due to what she told him before about acting on his guts and instinct more.
  • Team Mom: She's one of the instructors for Inaho and his friends, and serves as as a kind of mother figure for them. After she is WIA and unable to pilot a Kataphrakt, Inaho tells her she needs to reassure the civilian refugees and keep their morale up.

Second Lieutenant Koichiro Marito

Voiced by: Kazuya Nakai

An officer in the United Earth Army, he participated in the war against Vers 15 years ago. The scars of that conflict still weigh on him. Along with Yuki, he also serves as a Kataphrakt instructor for the students.
  • Action Survivor: He survived in the first conflict in 1999, although it left him embittered as a result. He also manages to survive Trillram's attack on his mecha in episode 2 due to only getting cut in half, but the top half where he was piloting manages to fall away before it can get vaporized by the Kataphrakt's attack.
  • Cassandra Truth: He's tried to tell people about what he saw 15 years ago, but apparently the UE government's coverup is so effective that nobody believes him. Even a fellow lieutenant in his platoon derisively refers to him as "a fraud."
  • Drowning My Sorrows: He seems to be a regular patron at his local bar, drinking to avoid dealing with the horrors he witnessed during the 1999 war.
  • Government Conspiracy: He knows something about the war 15 years ago that the Earth government refuses to publicly acknowledge.
  • Screw the Rules, I'm Doing What's Right: He deliberately gives orders to another squad not under his command when they run into Trillram attempting to kill Rayet, whom they assumed was a civilian at the time. While the squad's commander objects, his orders ultimately end up saving her by distracting Trillram long enough for Yuki to rescue her.
  • Shell-Shocked Veteran: He saw action in the 1999 war on Tanegashima Island, and he did not come out of it unscathed. Right before he and his platoon engage the Nilokeras Kataphrakt in Shinawara, his right hand is visibly shaking.
  • Veteran Instructor: Along with Yuki, he supervises the students in their live-fire Kataphrakt training drills.

Soma Yagarai

Voiced by: Kosuke Toriumi

A doctor who happens to know Marito, he is part of the group of refugees evacuating Shinawara.

Darzana Magbaredge

Voiced by: Ai Kayano

A captain in the UE Army, she commands the amphibious assault ship Wadatsumi.
  • Reasonable Authority Figure: While she was ready to abandon Yuki Kaizuka due to the fact that the chances of finding a single soldier in radio-jammed hostile territory being too slim, as soon as Marito told her there were civilians also trapped in the combat zone, she immediately authorized him to put together a rescue party.

Kaoru Mizusaki

Voiced by: Yu Shimamura

Magbaredge's executive officer on the Wadatsumi.



Voiced by: Show Hayami

  • Fantastic Racism: He has a very low opinion of Slaine, who is an Earth-born human, even though he appreciates the fact that Slaine is Asseylum's tutor.
  • Pet the Dog: He seems to genuinely care about Asseylum's safety, and all evidence indicates that he was not part of the conspiracy to assassinate the princess. He also seems to regret not being able to stop her from going to Earth on a goodwill mission, which later ends up killing her and becoming the justification for the VERS Empire to invade Earth.


Voiced by: Tōru Ōkawa

  • Big Bad: From what information we have, he is shaping up to be the main villain of the show.
  • Corrupt Politician: Corrupt enough to instigate a full-scale war between two nations through deceit.
  • General Ripper: He seems to have absolutely zero qualms about launching an orbital bombardment and raze an entire city to kill one kid who knows about the conspiracy. What's worse, Trillram warns him that he would also hit the landing castle of Count Cruhteo, who would consider this as an attack against him. Saazbaum doesn't seem to give a damn.
  • Manipulative Bastard: Most likely.


Voiced by: Takahiro Sakurai

A count of the Vers Empire who is part of Saazbaum's clan but has been living on Cruhteo's Landing Castle for some time. He pilots the Nilokeras Kataphrakt. He's one of the Martians privy to the conspiracy to assassinate the princess.
  • A Real Man Is a Killer: Mocks Slaine for his hesitation to open fire on the F-22 squadron engaging them and promises to show him "the joys of the battlefield."
  • Asshole Victim: By the end of Episode 3. Was it really wise to yell that it was your plan to kill the princess all along at her most loyal supporter whom you abused almost whole your screentime?
  • Blood Knight: He loves being in battle and killing people.
  • Even Evil Has Standards: Balks at the idea of using orbital bombardment solely to kill Rayet Areash, as it would also damage if not destroy Count Cruhteo's Castle.
  • For the Evulz: Done several times in episode 2.
    • When he's being airdropped, he deliberately flies into the path of one of the pilots that ejected to kill him, for no other reason than he wanted to kill people, even if they weren't posing a threat to him any longer.
    • Later he toys with the squad Marito and Yuki are with, and takes his time killing them one by one. He even wonders if Marito's last ditch knife attack is heroic or suicidal idiocy.
    • While pursuing Rayet and the other main characters, Okisuke attempts to rescue Yuki out of the mech after they seemingly lost Trillram. Unfortunately he shows back up, and Okisuke loses his balance and nearly flies off, though Inaho catches his hand. As they desperately try to hold on, Trillram utters a villainous Bond One-Liner {"Need a hand?"}, and stomps hard nearby, causing Inaho to lose his grip. Okisuke then falls back towards Trillram's mecha and vaporizes in front of Inaho.
  • Hoist by His Own Petard: A variant. Inaho figures out that Nilokeras's force field needs to have gaps in order to allow the mecha to walk and communicate with the outside world, so he submerges it in water to find them, disables it, and captures it. Also, the daughter of one of the men he murdered plays a key role in stopping him.
  • Implacable Man: He was way too obsessed with wanting to kill Rayet. Considering he was nigh-invulnerable at the time, he probably should have finished her off before dealing with those pesky Earth forces attempting to pelt him with bullets.
  • The Juggernaut: His Nilokeras Kataphrakt has a force field that disintegrates anything it touches, rendering conventional weapons useless against him. It's even able to literally walk through bridges and buildings as if they weren't even there.
  • Laser-Guided Karma: Slaine kills him when he realizes that he partook in the attempted assassination of the princess.
  • Manipulative Bastard: Asks Cruhteo for permission to enter the battlefield so he can plant the Vers flag at the spot of Asseylum's assassination. In reality, he's going out to kill the deep-cover Martian agents who did the deed so he can destroy all evidence of the False Flag Operation.
  • Mighty Glacier: His Kataphrakt was a lumbering beast compared to the other ones seen briefly, but it didn't matter since his Deflector Shields vaporized anything or anyone dumb enough to attack it.
  • Oh Crap: Has this look after Inaho figures out how to get around his mecha's shields.
  • Sink the Lifeboats: Deliberately steers the aerial ship transporting his Kataphrakt into the path of an ejecting enemy pilot.
  • Smug Snake: While in the safety of his Kataphrakt shields.
  • Villainous Breakdown: His smug demeanor starts cracking after Inaho and friends blind his surveillance drones with smokescreens and chase off Slaine's airship. The breakdown comes into full effect after Asseylum reveals she's still alive.

Rayet Areash

Voiced by: Sachika Misawa

A Martian girl who grew up on Earth as a sleeper agent. Her father attempted to kill the princess in order to please his superiors, but is killed to keep it secret.
  • Action Survivor: Becomes one thanks to the start of the war, and Trillram killing her father in front of her, along with attempting to assassinate her as well.
  • Deep Cover Agent: She's a Martian placed on Earth for years with her father.
  • Harmful to Minors: Witnesses her father murdered in front of her eyes by Trillram.
  • He Knows Too Much: She's a top priority target for Trillram, and consequently Saazbaum, as she's the only survivor of the Martian sleeper cell on Earth that knows the true circumstances of the princess's assassination.
  • Little Miss Bad Ass: She proves to be a very competent soldier.
  • Mistreatment-Induced Betrayal: The murder of her father completely turns her loyalties around. She has now elected to fight with the Earth forces against Mars.


Voiced by: Inori Minase

Princess Asseylum's handmaiden.

Rayregalia Vers Rayvers

The initial leader of the colonization effort to Mars, he spearheaded the creation of an independent Martian cultural identity by calling for independence from Earth. His efforts bore fruit when the Holy Vers Empire named after him was founded in 1985 with himself as emperor. His rule ended in 1997 due to health problems, and he was succeeded by his son Gilzeria. After Gilzeria was killed in action during the Heaven's Fall disaster in 1999, he has re-ascended to the throne. He is Asseylum's grandfather.
  • The Emperor: The founder of the Holy Vers Empire. In an unusual case of this trope, his reign ended, but then his son died and he had to be put back on the throne as Asseylum was still an infant at the time.
    • Emperor Scientist: The first survey team that crossed the Hypergate to explore Mars in 1975 was made up almost entirely of scientists and researchers, and he was their leader.
