Mr. Aizawa

Mr. Aizawa is Sakuyas father. A man with a strange sense of humor he is apparently proud of his naked conversation skills much to his childrens horror. Despite this he gets along very well with his younger children. He first appeared in episode 23 of the second season of the anime. He offered Nagi a salmon but she declined the offer. In the next episode he was seen triggering his own trap set for the missing Nagi. Source: Wikipedia
