Dai Ibuki

Ibuki Dai (伊吹 大) is a member of the Element Network. When Mamoru Hijikata and Haruka Tooyama temporarily leave the network to train, Dai is assigned to monitor Team Blade's area, with Ryotaro Igawa reassigned to Team Bucephalus. After Mamoru and Haruka return, Dai is added into the reformed Team Blade.

Dai rides Bucephalus, a state-of-the-art motorcycle designed for urban combat. His skill and stamina are such that Tatsumi Daiba saw him as the only person suitable to riding it, and personally trained Dai for the task.

History
Little is known about Dai's past, but he was scouted by Tatsumi Daiba for the express purpose of riding Bucephalus. He is one of the few members of the network to meet Daiba face-to-face, a rare honor he wasn't even aware of until he learns from Igawa and Juliet that they had little to no dealings with the man.

Daiba's training was apparently extremely harsh, and as such Dai sees the man's relatively lenient treatment of Mamoru in the present as favoritism.
