JOJO: Madness of Multiverse

Jotaro awakened his Stand at 17 years old, but unexpectedly bound to a bastard system. Under the system's effect, he was forced to go to other worlds. In order to return to his own world, Jotaro had no choice but to complete the tasks issued by the system.

Demon Slayer world: “Yare yare, Muzan, there's only one reason you failed, and that is, you pissed me off!”

One Piece world: “You bunch of guys, I’ll be the one to judge you!” While violently beating up the Celestial Dragons, Jotaro completed a research paper on sea king-type creatures.

Naruto world: “The one judging you is my Stand, Star Platinum!” Star Platinum, the true god of ninjutsu, ultimate hand sign speed. You call yourself the Copy Ninja?

Originally, Jotaro only wanted to find a traditional Japanese woman to marry and have children, but he seemed to have underestimated the Joestar bloodline's attraction to women. Unknowingly, the women surrounding him grew more and more, and all willingly.

The chatter of lovely women behind him made him extremely annoyed.

He suddenly turned around and shouted, “Yakamashi! So annoying! You stinky hags!”
