In this first installment of the series - we are introduced to Keisuke: mild mannered school-teacher by day - avenging angel of rape by night - and his goofy Uncle, who together run Rapeman Services. Their "services" are called-upon by a nightclub owner who tells a sob story about having her boyfriend, a current political candidate, stolen by his secretary, and asks Rapeman to "take care of her" as an act of revenge. This is done per the nightclub owner's request - but we soon find that the story was just a cover to cause a bigger scandal that involves rival a seedy rival politician and the Yakuza...

The story is about Rapeman and his Uncle who are a tag-team of sorts and created a company together where their motto is "Righting Wrongs Through Penetration". People want revenge Rapeman style, they go to the Uncle, and if it's rape worthy, Rapeman does what he does best. Anyways in Rapeman 2, Rapeman Co. has realized that the hospital and the mafia are somehow related and they decide enough is enough. What follows is even more of what you wouldn't expect from a movie called Rapeman. It's full of kind and silly humor but also inserted with a some serious emotional scenes.

Keisuke is a timid and nerdy high-school teacher by day, and a leather clad rapist "superhero" by night. One day, one of Keisuke's students is found dead, and her death is ruled an accident. Keisuke and the girl's mother don't believe her death to be accidental – and upon investigation, Keisuke and Uncle Shotoku unknowingly delve into an underground world of shady cops, scummy drug dealers, corrupt teachers, and a rape-porn ring. Of course, with Rapeman's upstanding moral values, he must do something to avenge the young student's death, bring down the criminals and right wrongs through penetration!

This episode starts with a request for a pop-star to be raped into humility by her personal-assistant, who the star had treated like crap. The pop-star get's hers when Rapeman shows her that she ain't always the boss. From there the story shifts gears when a Senator's secretary seeks out Rapeman's services to rape his fiancé who has been brainwashed by a local cult. According to the by-laws of the cult - if the woman has sex with a non-member, then she will be disassociated from the cult, thus bringing the wife back to her husband. This back-fires when the cult does not ex-communicate her - so Keisuke and Uncle infiltrate the cult to get to the bottom of their shady dealings. The resulting investigation embroils the duo in a conspiracy between the cult and a sleazy politician that can only be "righted through penetration"...
