Lol, it could only come from Japan, indeed.

Bell curve? Now, that's one system I rarely see. Well...not that much; most RPG systems either use a d20 for actions or a bunch of d10s and a hit/miss system.

Sounds tempting, but I'd give it a pass. Though...I have to check, but doesn't BESM uses a similar system? I'd be more inclined to do BESM than a specific sub-genre of anime.

It's weird, tho. I know of at least one other Tabletop RPG from Japan (it has to deal with superpowers, last I recall), and that game hasn't been translated already. That the one game they decided to translate tries to pigeonhole the craziness that seems to us inherent to Japan doesn't seem to help them that much.
