Koishikawa Jin
Jin is Miki's father. He divorces Rumi and marries Chiyako. Jin absolutely adores Miki although sometimes it seems like he could care less for her. He tries to be there for her as a parent and respects her. He likes the idea of Miki getting together with Yuu although he doesn't say this until the last episode. Jin is terrible at computer games. He seems the most concerned for the kids out of all the parents.
