Mana Tsuburaya is a second-year Coppelion, all of whom are considered defective since they constantly emit neutrons, making Mana and her peers into walking biohazards that waste living beings through their mere presence, except for other Coppelion. As one of the most powerful Coppelion, Mana can wield a wide variety of special abilities mostly revolving around psychokinesis and the control of gravity, such as the ability of flight (which she's using almost constantly to move), levitating other objects, stopping bullets, and creating violent shockblasts. Mana is working under Dr. Coppelius against Ibara and the others because he promised that he'll find a way to fix her defect. Alongside her best friend Meisa, she is a former member of Exploration Unit that went renegade just like the Ozu sisters. Mana's most notable personality trait is her being very quiet and stoic, initially to the point of appearing eerie to her adversaries. After her introduction in volume 10 she couldn't be seen uttering a single word until a volume later.
Umib�zu (means "sea bonze", which is a ghost in Japanese mythology; real name: Hayato Ijuin), is a "sweeper" in the underground just like Ryo Saeba. With his giant body, and his superb combat skills, he doesn't really need a partner. He is Saeba's equal in most things, and the two have somewhat of a rivalry going. Umibozu fought against Ryo back in Central America, and had his eyes damaged by Saeba. This should make them enemies, but both men shrug off the past since what happened in the war was not personal. That doesn't mean that they don't fight, though. They often find each other on the same case, but on different sides, and have dueled more than once.
The second pilot of Getter Robo, Hayato is portrayed as a psychopathic yet highly intelligent delinquent. He is first seen as the leader of a student revolutionary group, but is captured by the Saotome Research Institute after a fight with Ryoma and pulled into the Getter Robo storyline, initially as the pilot of Getter-2. He is the only character to have appeared in every Getter Robo series and has fulfilled many roles, from being a regular teenager to an adult colonel and an aging scientist. Like the other Getter Robo characters, his portrayal is drastically different in the 1970s TV series. While still a rebel and a loner, he is far less cold and cruel.
