I can't remember. I think the last time we had a really good look at the other Minami family was season 1, wasn't it? I think they made a brief appearance in Okawari, but both were so long ago I don't remember.
Yeah. I'd put Allen probably in my top 30 though. I like his personality and he's so handsome. Just finished watching Minami-ke. ^_^ I liked it. Then again, I may be bias since I absolutely LOVE Touma.
