Naota's Dad

Naota's dad is a little on the deranged side to say the least. He has a crush, and somewhat of a relationship with Harouhara Haruko, aka the Alien Chick. He often finds himself competing with Naota, and often very incensed to hear Haruko casually say, "Naota's manlier anyway."
My fave scene with this character is when he goes into manga style and asks Naota what does Furi Kuri mean. He suddenly burts out, "FURI KURI HEAD! FURI KURI THIS!" And then he points to his manparts and is naked. "FURI! KURI! FURI! KURI!" As I said, he's hilarious.
