I really like Honey & Clover, especially for the first couple volumes, but I'm thinking it might get old as it progresses. Other than that, D. Gray Man, FMA, Case Closed (Detective Conan), Love☆Com, Bleach, and One Piece. Basically I looked at my bookshelf and named all of them off XD
Um, Fruits Basket was my favorite for a really long time...I guess now I would have to say...either Captive Hearts, High School Debut, or Monkey High, since those are the ones that I search bookstores for.
I also love anything by CLAMP, Arina Tanemura, or Yuu Watase, MeruPuri, InuYasha, Ranma 1/2, Wild Ones, SA, Ouran High School Host Club, SGT Frog, Hot Gimmick!, W Juliet, Kare First Love, Binetsu Shoujo, and Emma (as those are the only books I can read off my bookshelf from this angle).
Hm, it's so hard but my top few would have to be The 9Lives, and FMA.
It's funny, a lot of poeple said Fruits Basket... whereas I could only read the first two (very reluctantly) before giving up.
Also, I was wondering if you guys could help me:
Is it worth it for me to actually try to get into Death Note and Ouran Highschool Host Club? And if so, should I watch the animes or read the mangas?
