Suzu is your typical school girl looking to live an ordinary school life...

...Up until she realizes that she’s attending a school populated with vampires, who have the ability to attract and hypnotize women for their own thirst.

Then comes Akishiro, a relatively quiet boy but is a vampire, who attacks Suzu and ends up sucking up most of her blood, to the verge of death.

However, what happens when Akishiro develops a weird affection for Suzu, where he can’t bear to see her being bitten by anyone else?
