After a string of failed jobs, Keiichi Oyamada lands work at a small manga cafe. Things seem to be looking up from day one. His best friend is his manager and he gets to work alongside the beautiful Rei Suzukawa. Also, his cute childhood friend, Kururu Hiiragi, is a regular—and she's all grown up!
So why couldn't Keiichi hold down a job before? Due to a series of bizarre coincidences, he always seems to end up having sex with every single female coworker! Although he hopes to finally end this deadly cycle, Keiichi will soon find out that bad habits die hard.
Keiichi Oyamada has a mysterious power that always makes him seem like a lucky pervert, as one way or another, he ends up having sexual intercourse with any female he meets. Due to this, he has never had a stable job as he continually gets fired from any place unfortunate enough to employ him.
One job opportunity arises when his best friend calls him to work at a manga cafe, which Keiichi reluctantly accepts. However, as soon as he starts his new job, he meets Rei Suzukawa, a fellow employee, and Kururu Hiiragi, his childhood friend. Both of them are very beautiful, and Keiichi fears that even they might not be spared by his lucky perverted powers.
