Ore no Kanojo wa Aku no Onna Kanbu + Bonus

The protagonist is a transforming hero.
For some reason, he fights against the evil organization that plagues the world using lewd, female-targeted weapons and special techniques.

By day, he is a young office worker.
Together with his seniors and juniors, he works seriously, passionately, and a bit intensely. But when the evil army appears, he transforms and battles them.

However, evil was already close at hand.
His senior at the company, Rie Arisugawa, is actually a female executive of the evil organization, blending into society as a disguise.

Completely unaware of this, the protagonist ends up falling in love and dating Rie Arisugawa.
But Rie also has no idea that her boyfriend is a transforming hero.
And so, day after day, they continue their erotic battles—each unaware of the other’s true identity.
