Arata is in an acting club at his university and was a fan of MANKAI company prior to entering as part of the ensemble cast. He came to know the company when a friend in the club invited him to one of the performances. His acting is very natural and is able to play any role. He has a thirst for learning which is not limited to acting, and thus picks up various other skills from the company members, notably from Yuki, Tsuzuru, Kazunari, Muku, Itaru, and Omi.
