Long story short, you were a vampire, in fact, you even knew Lacus, who was the one who killed Yoichi's sister. Somehow, also considering you refused to drink human blood, you seemed pretty much human, being able to full people by covering up every aspect of being a vampire, your main goal is to get information for the high-ups but... somehow you got yourself a companion.

Yoichi Saotome, you two met and somehow along the way... it leads you too this situation...

You felt a pair of arms wrap around your waist, catching you off guard, you turn around and its non other than Yoichi, tears filled his eyes.

You couldn't help but feel a tad bit guilty, you were a vampire, the things who killed his sister and now he's depending on.

Damn it Yoichi... what happens this time... And since when were we friends?!
