He is part of D-Four Production and the leader of the idol unit ACE.
Asuma is a playful leader who enjoys showing affection with "rough, physical" gestures- such as punching a guy or tickling him while telling him to be in a better mood or lighten up. However he is unable to take it back, and will quickly stop and apologize if one of his unit mates was to threaten him. He has a tendency to call other, younger idols "cute" or other "complimentive" terms.
