Mr. Aizawa  

Sakuyas Father, 咲夜の父

Mr. Aizawa is Sakuyas father and possesses an unusual sense of humor. His children find this amusing, although they are often horrified by it. Despite their initial apprehension towards him, he has a great relationship with his younger kids. He first appeared in episode 23 of the second season of the anime. In that episode, he offered Nagi salmon but she declined. Later on, in the next episode, Mr. Aizawa was seen setting up his own trap for Nagi who had gone missing.
