JOJO: Madness of Multiverse Novel

At seventeen, Jotaro awakened his Stand but became bound to a mysterious system that forces him across multiple worlds. To return home, he must complete the system's tasks. In the Demon Slayer world, he confronts Muzan with overwhelming power. In One Piece, he judges the Celestial Dragons while researching sea king creatures. In Naruto, his Stand Star Platinum becomes the ultimate ninja tool with unmatched hand sign speed, surpassing even the Copy Ninja. Originally seeking a traditional Japanese wife, Jotaro underestimated the Joestar bloodline's appeal. Women increasingly surround him, all willing to stay by his side. Their constant chatter grows unbearable, and he finally erupts in frustration: "Yakamashi! So annoying! You stinky hags!" Jotaro must navigate four worlds—Demon Slayer, Tokyo Ghoul, One Piece, and Naruto—while managing both his mission and the unwanted romantic attention that follows him everywhere.
