The Dark Blue Vampire

On that day, the protagonist was attacked by a vampire, and became one himself.
He is told a vampire can only live by "sucking" the blood of others, but he can achieve this by simply touching with the palm of his hand.
And so, he has no choice but to chase after the only fitting partner in the school for it, Itsuki Yasaki.
He starts her "bloodsucking" with simple touching, but as though he is being manipulated by someone, he becomes more intense, and ends up raping her.

* Battles are for bosses only, with action and command battle modes.

*While the protagonist is a vampire, there is no actual bloodsucking, just regular H. There is no depiction of blood outside deflowering.

*This game only has happy endings

*Spoilers*
