I haven't read many japanese novels but i like Psycho Busters! It's so nice to read and watch Rando's art at the same time : >
I totally forgot about that one! I read it before! It was VERY good! Must be getting old or something!
I rather enjoy Koukaku no Regios. Found out about it after seeing the anime, so I watched that, then went and looked to see where it was adapted from.
I discovered it the same way! The anime was pretty good! The novel just added more!
