I have to say, at this point of the story i HOPE Ryu and Taiga end up together. I dont know...it´d just feel so stupid and boring if they got their "victims". Taiga only admires Kitamura while another boy is doing everything for her, and Ryuu seems to have no relationship to Kushieda at all. Sadly, Ami wont play a role, she´s definitely just there to make things more interesting for us watchers. THAT would be an unusual ending, if Ryu did end up with Ami, haha-
And now, talking about the initial potential of the series:
I actually thought the series would go along the lines of "boy who looks evil but is nice makes contact with girl who really is "evil", and by these circumstances is pushed near her, thus getting into interesting situations. That´s what i thought after the first episode, and i would have totally prefered it :-/
Also, in that one scene in episode...1 or 2...where Taiga kicked around all the stuff of a classroom at once, i thought the series would involve magic or some kind of martial arts (like Tenjou Tenge), haha.
Whatever, i´ll keep watching.
