Hello Vampire DESU!!!

Beautiful, super sexy, but in reality she is a VAMPIRE!

Akiyama Yuuto has decided to serve at the  Ijuuin mansion in order to atone for her father's sins. However his time is limited and he will die soon as he has had his spirit life sucked by a beautiful voluptuous vampire that looks a lot like one of the Ijuuin sisters, Serena-sama, who has fallen in love with Yuuto.

Yuuto is surrounded by beautiful voluptuous girls in the mansion, but he does not realize yet the secret of the Ijuuin daughters...he is to become a male sacrifice ...
