Haruki is a school nurse by day, natural-born manhunter by night. Lately, though, he hasn't been able to catch any prey. As his frustration reaches a boiling point, he is approached by a mysterious young man named Shion. "Give it up. I'm only gonna stop you." Haruki laughs this off, believing it to be some kind of immature revenge plot. Shion seizes this opportunity to push Haruki down and bind his hands. In a state of rapture, Shion says, "I've been told I'm pretty good. So, all you gotta do is sit back and take it." Despite not usually being on the receiving end, Haruki can't help but lose himself to the pleasure...!
