Kyoko's father= Director Kurosaki Ushio?!!!

and who is this director kurosaki? I can't quite remember

Kyurara ad's director

eh really? I guess I need to re-read this manga again ╮(￣▽￣)╭

Would it not be interesting if he was her father and some event years ago made his box open up and twisted his personality just like Kyoko.

I don't think he looks like Director Kurosaki at all. In Saena's flashback, the Dad's already been through college, and ready to take the Bar exam. No mention of being an actor/director/porn star (oh wait, that's just my imagination having fun)
