Billy Bat
Complete | Urasawa | 2008 released
Probably the best manga I've read in my life. It was so interesting.
Bloody Monday
Complete | RYUUMON Ryou | 2007 released
Had an interesting premise but ended up a generic shounen title. Still had anime tiddies on one of the covers, which was great.
Boku Dake Ga Inai Machi
Complete | sanbe kei | 2012 released
Had an excellent anime adaptation, and the manga was very good as well.
Death Note
Complete | ohba tsugumi | 2004 released
Ahh, Death Note. One of the most famous mangas ever created. But if you actually do read it, it gets tiring. Could have definitely been a shorter work. But, this had an amazing concept.
Dragon Head
Complete | Mochizuki Minetaro | 1995 released
Now this was very good. Could it have been better? Sure. But is it worth reading? You bet your yaoi-infested mind it is.
