With his attractive body and alluring beauty, arch-incubus Akira has no trouble overcoming his prey with intense bouts of pleasure. He's one of the many demons who live peacefully disguised amongst humans, and he harbors a grudge against the demon-slayer clan who, in addition to being his natural enemies, murdered his best friend.
This leads him to target the murderer's son Kurogane, hoping to gain a servant who'll double as his own dedicated source of sustenance!
However, Kurogane believes intimacy should be reserved for couples, and he firmly rejects Akira's advances. When Akira tries to get Kurogane in the mood with some special hypnosis that can only be used by arch-incubi, it doesn't work on him at all for some reason...!
Sparks fly when a gullible but straight-laced young man meets an arch-incubus who's had plenty of experience!
