(Y/N is a supernatural and somewhat immortal mass murderer who kills abusive parents, NTR cucks, rapist, and any sex predators. He's also got a massive harem which is also immortal. One day, Y/N is seen with Akira Todo as both of them see two mean adults abusing a child.)
Male Abuser: Why are you still alive, you worthless brat?
Female Abuser: Your existence just brought us problems.
Y/N: Time to do my job.
Akira: Let's go, dear.
(Then they kick the door as Y/N approaches the abusers.)
Male Abuser: Take this worthless kid, and leave us alone!
(Y/N shakes his head in disgust and throws his big knife at the male abuser, much to the female abuser's shock. Then Akira smirks deviously and starts stabbing her to death.)
(Next day, Y/N is seen with Yumeko as they see some NTR cucks claiming a woman.)
Yumeko: Such disgusting fucks...
Y/N: Time for them to die!
(Then they kick the house's door and Y/N slowly approaches the cucks before beheading them all, as the woman gets scared and tries to run away, only for Yumeko to slit her throat with a card.)
(Some hours later, Y/N and Ahri see a young girl being cornered by rapists.)
Y/N: You know what this means, right?
Y/N: Indeed, my darling.
(Then Y/N approaches them as he turns on his chainsaw, drawing the rapists attention.)
Rapist Leader: GET HIM!
(The rapists draw their guns and shoot them, but the bullets can't kill them. The rapists get scared and try to run away, but reach the dead end, and Ahri kills them while Y/N brutally kills their leader with his chainsaw. The girl simply runs away, thinking she would be the next victim.)
(And finally Y/N and some shipgirls are seen preparing an attack in a club, where some sex predators are located.)
Roma: So this is where those motherfuckers are hiding.
Bismarck: Time to show zhose pricks what happens when they mess with women.
Akagi: Ara ara... I can't wait to punish some disgusting perverts.
Kronshtadt: And with our Y/N by our side, nobody can stop us.
Enterprise: Let's get them!
Belfast: Yes, ma'am.
Hwah Jah: Now?
Y/N: (draws an axe) Now!
(They invade the club and the true terror starts as the sex predators are easily killed either by Y/N or at the hands of the shipgirls.)
(After they're done, Y/N and the girls return to their lair which is located in the middle of a forest, where they live peacefully.)
