BB Senshi #158 Tenrei Gundam [Kirahagane Gokusai Ver.]

Tenrei Gundam (Wing Gundam Zero)

Tenrei Gundam is a warrior with amnesia. Despite having lost his memory, he retains a sense of morality, choosing to fight against the Hyakki Yako and joining the Gundam Corps. His appearance and behavior have led others to compare him to the missing Kotomaru, speculating that he might be "a return from beyond time" or "reincarnated," but in reality, he is a disciple of Kotomaru. Five years ago, he was killed by the Hyakki Yako (in the manga, he died protecting Kotomaru from an attack by Jarei) and was resurrected through the revival techniques of Hado Gundam, sharing his soul with Kotomaru. However, this resurrection caused his memory loss. In combat form, he can transform into the Oni Blade Flash Sky Slash form, unleashing the celestial technique Oni Blade Flash Sky Slash. He can also assume the Kiragane form when adorned with the sacred artifact of Kiragane (in this state, Kotomaru’s consciousness comes to the forefront).

The name "Tenrei" was initially a provisional name given by Beastbreaker based on his appearance, but it turned out to be his real name by coincidence. In the manga, this name was decided by Ryuliu because of the character for "zero" found on his armor and the fact that he appeared from the heavens, which was later confirmed as his real name. According to childhood friends, he was described as "a wild yet kind and good person" when he was a child.
