When it was discovered that Blaster was Buiou's younger brother, Takenosuke, and was about to be awakened as a musha of light by the Evil Destruction Arrow, Jarei absorbed Blaster and was reborn as a Yami Gensui with the power of gundamu. He plans to reopen the door to the Demon World and completely revive darkness. He is a terrifying incarnation of darkness that combines the power of both darkness and gundamu, and his special move is the Evil Dragon Demon Blade Darkness Slash, which simultaneously unleashes the Demon Blade One-Slash and the Evil Dragon Whip. Since he has absorbed Blaster's body, the Gundam Army are unable to finish him off, but some of Blaster's consciousness still remains, and he has not been fully resurrected as a Yami Gensui. However, he is still an incarnation of darkness and has terrifying power.
