Neo-Japan
- Ulube Ishikawa (ウルベ・イシカワ, Urube Ishikawa?)
- A major in Neo-Japan's military and former Gundam Fighter from the Twelfth Gundam fight, Ulube was the mastermind behind the Devil Gundam incident when he led the siege against Kyoji Kasshu that resulted with his facial scar which forced him to place a metal plate on his face and thus resembles the Phantom of the Opera. After successfully framing Kyoji and silencing Dr. Kasshu, Ulube recovered Dr. Kasshu's research notes and was convinced by Dr. Mikamura that the Devil Gundam would resurface during the Thirteenth Gundam Fight. Using Dr. Kasshu's son, Domon, and Dr. Mikamura's daughter, Rain (much to Mikamura's protests) secretly as pawns, they would track down the Devil Gundam, using the Gundam Fight as a cover, with Ulube faking sympathy toward Domon and pulling favors for him. But once Kyoji is dead and the Devil Gundam acquired, Ulube uses Wong's notes to complete his agenda, making Rain the Devil Gundam's new life core unit as it absorbs the Neo-Japan Colony. In the end, the Devil Gundam overwhelms Ulube and he completely loses his mind and body to it while fighting the Shuffle Alliance in the Grand Master Gundam and was able to outmatch them, until Ulube was killed when the Shuffle Alliance combined their energy to use a team attack to destroy Grand Master Gundam. He lays dying for a short time muttering on how resistance against the Devil Gundam is futile, before disintegrating.
- Dr. Mikamura (ミカムラ, Mikamura?)
- Other than being a close friend to Dr. Kasshu, he is also Rain's father, known as the original developer of the Shining Gundam. Because of his jealousy towards Dr. Kasshu, Dr. Mikamura played a part in the Devil Gundam Incident and felt guilty of his part in it since. When he attempted to silence a wounded Schwarz, Mikamura exposed himself to Rain as she was in the room at the time, revealing herself after learning the truth. Rain convinces her father that his foolishness had caused for the members of the Kasshu family to suffer which lead him to reconsider his actions. After helping Allenby recover from the DG Cells, Mikamura apologizes to his daughter while revealing his intent to turn himself in for his crimes and acknowledging that he doesn't deserve to be her father. But when Ulube reveals to Mikamura his intent with Rain, Mikamura got shot when he attempted to have his daughter escape and tried to radio for help. In the end, the mortally wounded Mikamura sacrificed his life by releasing Dr. Kasshu's capsule into space, so they might have a chance against the Devil Gundam. Moments before his death, even though he knew he did not deserve such treatment, he pleads with Domon to save Rain and tell her to not blame herself for his past actions.
