yeah Dr. slump is in black and white, you can get it at toriyama world. i too am vigorously looking for furigana manga, ive been watching fansubs for 3 years and ive been learning japanese for 2 years, and ive been learning kanji for 1 month, so getting some furigana manga would really help me out. however i dont care about color. i have seen 3 episodes of mahou tsukai ni taisetsu na koto anime and it's really girl friendly, its is a shoujo manga, and hale nochi guu is a funny neutral anime.
oh yeah, chobits and fruits basket, are also very very good,
to tell you the truth, ive never actually read a manga. ive just seen a lot of fansubs, so if i liked the anime that means that the fansubs is just as good or better. i have seen one episode of fruits basket and it looks like a good shoujo anime.
