Reiji Moritsugu

Voiced by: Yuuichi Nakamura (Japanese) and J. Michael Tatum (English)

25-year-old Commander of JUDA's Special Task Force and Vardant's Factor.
  • The Ace: In the manga, Hayase even stated that Moritsugu is the role model the he want to become.
  • Ace Pilot: And how!
  • Blood Knight: As a kid he would used to get into fights under the pretext of "being an ally of justice". A recent battle in the manga hints that he still has that tendency.
  • Curb-Stomp Battle: His first two fights with Koichi consist of nothing but him beating the crap out of the poor kid. However, he gets on the receiving side of this trope in the anime when Emi gets in Linebarrel's cockpit.
  • Dark and Troubled Past: He grew up being raised by his sister and upon finding out he can't feel pain, starts getting into fights, and that eventually ends up getting him in trouble with the law.
  • Fake Defector
  • Feel No Pain
  • Four Eyes, Zero Soul: Because of his past, he has trouble empathizing. In both stories, Kouichi remedies that, though Character Development goes further in the manga.
  • Genius Bruiser: He's well educated about things, and quite a mastermind in the manga.
  • I Am Not Left-Handed: One of Verdant's eyes appears damaged and when Koichi attempts to attack him from his "blind side", Reiji has the eye heal at that moment.
  • Mundane Made Awesome: In the manga, he makes having a bunch of bags along his arms look quite dramatic. Koichi attempts to do the same and fails.

  • The Stoic
  • Stoic Spectacles
  • Tall, Dark, and Snarky

  • Action Girl
  • Badass Adorable
  • Beware the Nice Ones
  • Broken Bird: She was already being bullied to the point of committing suicide, but after the timeskip she gets fired from her job as an idol singer because the factors joined with Katou, her fans turn on her, and her wanting to kill them ended up turning Deceive into a humanioid, leading to Izuna's death.
  • Canon Immigrant: Originally a character created for the anime, who eventually made it into the original manga, albeit with a completely different story and personality.
    • Subverted: She was originally made for the manga, but the anime decided to introduce her much much earlier, using only the bare-bone early manga design notes as a base.
  • Decapitation Presentation: In the manga.
  • Every Girl Is Cuter with Hair Decs: Her huge pink ribbon.
  • Gag Boobs
  • Heroic B.S.O.D.: In the anime, after Masaki gives her a nasty "The Reason You Suck" Speech, telling her that she's too weak to be a Factor.

  • Killed Off for Real: In the manga.
  • Nice Girl: At least in the anime.

  • Rescue Romance: About the one thing her anime self and manga self have in common is her falling in love with Koichi after he saved her (though in different ways).
  • Senpai Kohai: After Koichi gets into high school, Miu turns out to his senpai. Ironically, some time after they find this out, Miu becomes Painkiller's Factor, and she noted that this time, he's her senpai.
  • Start of Darkness: Izuna's death in the manga.
  • Yandere: The manga version of her is... different. In fact, she's so fucked up in the head that Painkiller made her its factor believing she was dying. She finally snaps after Kouichi disappears when the Time Skip happens.

The Endou twins

A pair 14-year-old twins who are both Factors for Deceive.


Voiced by: Kana Ueda (Japanese) and Cherami Leigh (English)

Izuna's loud and energetic older twin sister and a member of JUDA. She controls Deceive's movements. When the Deceive is destroyed, she does the same in Deceive V, a Kiriyama-made Arma mimicking the functionality of the original Machina, with Domyouji taking Izuna's place.


Voiced by: Rie Kugimiya (Japanese) and Aaron Dismuke (English)

Shizuna's more reserved younger twin brother, also with JUDA. He controls Deceive's Never Crack cables.

     Katou Organization 

Hisataka Katou

Terror syndicate Katou Organization's mysterious leader. He pilots the Arma Tsukuyomi. Factor of the Shangri-La.

Masaki Sugiwara

Voiced by: Susumu Chiba (Japanese) and Tony Patterson (English)

Factor of Glein-Neidr, and, by extention, Naked, and Captain of Katou's 1st Squad.
  • Authority Equals Asskicking: He's the top ranking captain of the Kato Organization, and also the best pilot.
  • Breaking Speech: He becomes fond of these as the ending of the anime comes close. They work on Miu but not on Koichi.
  • The Dragon: To Katou in the manga. In the anime, he acts like he is, when in reality, he is this to Central.
    • The Lancer: Since Katou has decided to become the Big Good in the manga, that would make Masaki this.
  • Heel–Face Turn:In the manga, with the rest of the Katou Organization.
  • Never Got to Say Goodbye: The reason why he's so pissed off with Ishigami in the manga; he literally treated him like his own father, and is justifiably upset when he left them with no explanation immediately after mounting Juda.
  • Nice Hat
  • Peek-a-Bangs: Justified in the anime. He needs it to hide his cybernetic eye, which would reveal that he's a Machina Human. Not quite explained in the manga.
  • Superpower Lottery: The beam spamming heavily armored Glein Nieder is much much better than all the other Machina. Even Linebarrel can't dent it without help. AND it has Naked inside it.
