Dang I hate it when they introduce a character just for the pure purpose of filler material for a series. I hope I'm wrong, but so far this shows all sign of it.
@kojiro481 Hm, they're both kind of on the introvert side though. They might get along okay like that, but I wouldn't say they'd necessarily thrive like that. A lot of Manabu's best moments might come from Megumi and the others around them kind of pushing him out of his comfort zone.
