Thread: Who's Horohoro's dad?

Okay, I'm trying this again since apparently people didn't pay much attention to my first post. Anyone know anything about Horo's dad? (Or his mom?) I heard his dad appears later in the manga after Ren gets resurrected (oops, spoiler? Sorry...). I've been trying to find info on the internet but haven't come up with anything. Help?

Ok, sorry, I know nothing about his dad other than his name. He is Oyaji Usui. (HoroHoro's real name is Horokeu Usui.)
