eeh, guys i've read Bakemonogatari synopsis and kinda remembered a manga about a long haired vampire girl with a boy didn't the rest... and that's kinda disturb me.

so try to tell every single manga that revolve about vampire girl or has vampire girl in it

This thread on vampire stories will help you.

If you've ever thought or said "Nice Guys finish last" and really meant it, then you should probably read this LJ post by DivaLion. It's incredibly insightful whether you're male or female.

From a bumper sticker I like:
"If you're gonna ride my ass, at least pull my hair."

So, you're looking for a forgotten title? I'm a tad confused by your first post, or perhaps I'm just illiterate. : D

Otherwise, I suggest Vampire Girl (no pun intended), and Vampire Knight.

The thread suggested above ^ will help you greatly in looking for every type of vampire story. This one as well in vampire girls.

nah, it's my English that sucks 🙁

ah, thanks for the response. 😀

thanks to Liria, i remembered the title "Lament of the Lamb"
