Kamiki Koreomi

The protagonist's father and head of the Kamiki family.
With his stand out looks you wouldn't think he's a normal salaryman, but mysteriously even his kids don't know his real job.
Because of various circumstances he adopts Setsura and the other girls into the family.
He's a little teasing toward his son who is treated nicely by all the girls, but he's a normal father.
