Anime Crossover: Coming and Going Between Worlds

Also known as “Playing Tennis with Breathing Techniques and Cursed Techniques” and “I Ended Up Together with My Favorite in Another World.” A self-insert romance with Jack, so proceed with caution if that bothers you. Zhen Sakurada is an unaffiliated sorcerer whose technique, [Wormhole], is both bizarre and powerful, allowing him to travel through time and space. But this very ability has brought him ten years of suffering. He can’t control it, which means he can’t stay in any one world for long… After arriving in another world once again, he learns to play tennis using Breathing Techniques, makes plenty of friends, and reunites with old ones. The memories he deliberately tried to forget keep reminding him that he has always been a wanderer, tossed from place to place. But one day, someone tells him that he is his biological older brother. Zhen Sakurada: What is this guy even talking about? A crossover between Jujutsu Kaisen, Demon Slayer, and The Prince of Tennis (for now; more may be added later). A slight reverse-harem vibe, so stay away if that’s not your thing. The writing is rough at first, but it gets better later on. I hope you’ll give it a few chapters and be patient.
