Maybe I've read too much RP games, but I say:
GinxMatsumoto
IchigoxRukia
OrihimexIshida (these 2 are made to be together!!)
Hitsugaya is a character I adore, but I cannot really see him with someone, he's too young compared to the other main characters. Maybe with Hinamori. Even if it's true that she only cares for Aizen.
