Daisuke Asakura
is the keyboard player in Nittle Grasper and Mika Seguchi's husband. He is the head of N-G recording company and demands the best from all his contractual bands. Tohma is very protective of Eiri Yuki, and blames himself for the trauma Eiri suffered as a teenager, seeing that he was the one who hired Yuki Kitazawa in the first place. He has declared Eiri as his dearest. He is unfailingly polite to the point where he will refer to anybody (including his wife) as -san, and appears to be a friendly and even-tempered person (if also a ruthless businessman). As the series goes on, it becomes evident that much of this is a carefully constructed mask: when Eiri is involved, Tohma has been known to be far from rational and soft-spoken. Tohma is an anime-adaptation of Daisuke Asakura, who wrote most of the music for the series
