Ikeguchi Wataru has a sexual addiction! But the young virgin has to take care of it himself. Logically, of course, this is all caused by a parasitic demon who eats arousal. Maybe that perverted foreign doctor and the Chinese Taoist potions master can solve the problem.

The extra hasn't been scanlated.

The give & take relationship. Hellsing (Dhampir) gives his body to Tayuu, while Tayuu gives Hellsing his body fluid. When Tayuu and Hellsing meet, all they do is argue, and have very kinky sex...

"I want to touch" "I want to dominate"... Tayuu doesn't understand the reason why he wants more. And Hellsing can't have a "beloved person" because of what he is....

The problem is, Atsumi is not only a guy, but also a vampire hunter... Their love is more than just complicated, it's a game of life and death for them both!
