Diabolik Lovers: Anthology
That is Batoto's link so you can find it easy!
Now that we have that out of the way.... Lets meet our main leading lady...
Hello there Yui!!! Isn't she cute!!! I am not sure if she has good or bad luck at this point... I didn't read every one of the Manga after all... And it gets confusing in them if she is happy or upset about the whole situation. All the Manga are ongoing (maybe only in translation??) and some are in a different language than one I know... So I had a hard time figuring it out. There are times she seems happy and times she seems like she wishes she didn't have to deal with all their crap.
Oh ya... By "their" I'm talking about the amazingly beautiful Sakamaki Vampire Brothers she now lives with. (I found the last name somewhere... Maybe on the wiki but I don't remember)
Lets meet them shall we!
What hotties lol... But each is twisted in their own special way...
I guess that's the price of being a vampire!
