For a 11min episode it's good. But to agree with me 1st you have to be a lil bit into -this- kind of sadist stuff.
Sad thing about this anime is that main character Yui is boring af. Like... if they just putted a chair instead of Yui.. it would be the same. But anyway. This ova is a decent intro for season 2 Diabolik Lovers More,Blood. You get to take a taste of what new characters are like what you should expect for s2 and that's it.
Story : is there any story? :D
Art : It's really good actually.
Sound : Is really good too.
Character : Well every character has it's own beauties. EXCEPT YUI. booooooring *throws tomato*
Enjoyiment : 8 . Well I didn't have anything more important to do. Was good.
Overall : Good.
