I was going to say that I think there's a thread for this, but they were all wiped out thanks to that @#%$ of an ezboard hacker. ^^;
But yeah, my favorite character was probably Osamu Kasai, just because he looked different than the others and I enjoyed what he did near his end. Masami Shibaki was cool too.
And finally, characters that I liked yet never got to know are:
Yuko Natsukawa Rena Niimi Kazumi Fukuda Ryoko Hata Hibiki Yano
I wanted to see all of those characters more. But unfortunately you only see Ryoko and Rena for a brief vague two seconds before they get blown up. We all know what Hibiki's deal is, but at least she gets some lines in. Well, maniacal screaming would be more precise. Kazumi died first... then Yuko got gipped with how she was the only one who blew up when like two or three other girls' collars were beeping.
I'd go for the Ganjuro girl. Why? Because she got totally screwed. Unlike everyone else, not only was she not under attack or attacking when she died, but she hadn't even done anything to be killed... her "partner" did.
Main characters: -Osamu was so graceful, too bad he was in love with Kyoko, 'cause she was a very, very annoying girl and looks like she dislike him. -Shiori was the only one character who get the feet on the ground and the only one who acts really good. Not Main: -Rena Niimi & Ryoko Hata: two of the "Powerpuff Girls" (that's the nickname I gave them and Miki). -Hibiki Yano: She was so cute!!!! -Kana Yuki: The "killer stare". -Eri Yoshiyama: The white t-shir honor student/bully.
kitano shiori. she's the only one in the class that has actual arms training, and it seems she knows judo/aikido as well (she flips taku, and pulls off some quick one-shot hits on people). always composed, she doesn't stray from her self-imposed objectives. maeda ai is hot, too. :3
if taku was a bit more composed, and less rowdy, he might be another favorite. and actually, majority of the students weren't really given a chance to show their personalities onscreen; that's a real bummer, and limits the resulting choices way more than the first movie. the only characters you didn't really get to know in the first installment were fujiyoshi fumiyo and tendo mayumi (and kuramoto/yahagi if you didn't read the novel/manga).
It's been forever since I watched BR2 (my friend still hasn't given it back, and he's had it almsot a year) but my faveourites were Saki's brother *forgets his name* and the Shwartz Katze (all except the non-cute one ^_^)
"Daddy loves the horses..." these island people and thier strange ways...
My favorite character in BR II would be Kitano Shiroi!! Even before the acual game started I liked her. And I just liked her more and more throughout what I saw of the movie so far (I watched it at my friends, and didn't get to finish Y_Y) And Maeda Ai is like my favorite actress, so yeah. I kinda liked Aoi as well... he had cool hair.
