Daigo-sensei seems very kind and honest person. He does volunteer work in Cypress Park Orphanage(/Child Warefare Facility Asunaro-En), where he takes care of "child errors". He is pretty good cook, or so he says and he would love to get married and cook togeteor with her wife, so he says it is a dream of his. He is also Tokiwadai middle school dormitory supervisor's love's target.
