Mr. Aizawa is Sakuya's father. A man with a strange sense of humor, he is apparently proud of his &quot;naked conversation skills,&quot; much to his children's horror. Despite this, he gets along very well with his younger children.<br /> <br /> 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.<br /> <br /> (Source: Wikipedia)<br /><br />
