Shinichirou's and Soushi's older brother. He has a psychiatric clinic and he does double-personalities-analysis to Sora and to Sunao (with Soushi's and Nanami's approval, though the same can not be said for Sora and Sunao). He brings always with him a pink rabbit and does ventriloquism with it to his adopted child, Kano-kun (seemingly a bit unexpressive and shy enough). Smiles often and loves children. (Wiki)
