Once you get to the later volumes, I'm sure you'll all agree with me on this:
Watanabe. GodDAMN that dude is messed up. I mean, throughout the series he's pretty damn weird to begin with, but you can almost respect him for at least TRYING to act normal. He's not even trying anymore. Plain and simple. He's got that CREEPY-ASS look in his eyes all the time now, and just thinking about what the hell's going on in his mind is downright FRIGHTENING.
Umi's stupidity pales in comparison, ladies. You KNOW that it's true.
I was thinking...does anyone remember the trip to the sewer? And Wantanabe woke up with Hyatt dead on him? And excel kicked him in the head...but it was afterwards, i was actually surprised he did: told his friends and they made out he was a real sicko and they decided it was a dream...
Afterwards in book 4, he started thinking that it was himself being perverted...
What I think happened, is that he started seeing himself as a pervert because of that.
I still he think he really is just a nice guy, he doesn't talk about her that much in the book, and im thinking of book 9, where he sees Hyatt after thinking he'll never see he again, and Misaki says "You're happy...aren't you...?", just because seeing her makes him happy. aaaaaaaaawwww.
But yeah, gotta agree that in the anime, got really annoying having him never shutting up about Miss Ayasugi...heh heh
