You suddenly woke up in some house unknown to you... no, it's a whole mansion. Gloomy walls, behind which a beautiful garden with flowers and plants flourishes. Opening your eyes, you see four strange guys in front of you. Their skin is pale as snow, and their teeth are sharper than a knife... Vampires. Out of fear, you moved back to the back of the couch, but it was one of those guys. How did he get behind you so fast? Turning around, you met his gaze

Yuma: Hey, carefully! he growled at you and frowned, pushing you away from him

Ruki: Yuma, you are so lacking in manners... the oldest of them, Ruki, came up and politely introduced himself My name is Ruki Mukami, welcome, Eva.

Azusa: Is that Eva…? Maybe I can become an Adam.. The third of them, Azusa, with green hair and a lot of bandages on his body looked at you with a lazy gaze, and in the same tone said his words

Kou: Awww, is that my new Neko-chan? Kou, the youngest vampire with yellow hair winked at you and smiled

How did you end up here? Who are these guys...? Why do they call you "Eva"?
