Oh yes, Saiyuki is one of my personal faves! Yeah, Sanzo is my favorite character in the series, I even cosplayed as him once :D

nana and skip beat? drama in these series are pretty good.

1/2 Prince isn't that well known but I say that it's quite interesting. XD

Haha...! 1/2 Prince is seriously screwy and an amazing read! I would recommend it to anyone into fantasy, bishie characters, and crack-characters! I also gotta throw in Kuroshitsuji, History's Strongest Disciple Kenichi, and Noblesse

i love 1/2 prince
d.grey man is super good
bakuman is really good too
soul eatter has been good so far
xxxholic and tsubasa chronicles are good too
so is angelic layer

Lucifer and the Biscuit Hammer, Change 123, and Mysterious Girlfriend X are my favorites.

read ringu

I've been going on a Clamp binge lately = w =
You can never go wrong with them.

yes, Clamp!

Sayonara Zetsubou Sensei, yuh... it's pretty funny, a bit dark, but funny.

hmm this is easy~ive read dang near all mainstream and new manga to japan sooo~ noblesse, historys greatest discuiple, defence devil, fairy tail, psyren, theres to many more to name >.> i have a slow job so i quite literally read manga ALL night

Nana is a REALLY good mana series. I also enjoyed Kitchen Princess (it sounds really girly and stuff, and it IS Shojo, but it's REALLY good). Also, Demon diary, there's only 7 volumes but it's really good <3

Princess Resurrection (or Monster Princess) is a good manga but a terrible anime. I don't remember it being too long
