So basically, you're asking for any character with decent boobage, yeah?
Love Hina and Code Geass
have a lot of curvy women.
Mikuru from The Melancholy of Haruhi Suzumiya.
Yaone from Gensomaden Saiyuki. (Though those are kinda, er, Tsunade-fied O_o; )
Mai from Yu-Gi-Oh!
Hevn from Get Backers.
Hinata (after time skip) from Naruto. (I think? I can't really remember...and of course there's always SNJ!Naruto who's pretty curvy lol).
Fuko from Flame of Recca. (Or, at least she looks curvy in some shots O_o; )
Sei and Meg from Burst Angel.
Miranda from D.Gray-Man. (In her exorcist outfit anyway. Weird, she was rather flat first time you see her and a month later when she appears again, she grows boobage xP...Lenalee too but I'm not sure...)
Eliade from D.Gray-Man, as well.
Rinslet, Echidna and Tearju from Black Cat.
Yamato and Yuiko from Loveless.
The two girls from You're Under Arrest (can't remember their names -headdesk-)
Yumi from Rurouni Kenshin.
Meer and Stellar from Gundam Seed/Destiny. (Though more or less all the other girls are relatively busty.)
Chocolate and Tira from Sorcerer Hunters.
Mirielle from Noir.
Hope that helps x) Sorry in case I misunderstood what you means by curvy -headdesk-
