A Tennis-Playing Wizard in Jujutsu Kaisen

A crossover mainly featuring Jujutsu Kaisen and The Prince of Tennis. The timelines are all over the place, and I’ll write wherever the story takes me. Note: I got confused while writing the Prince of Tennis part, so I’ll be making major revisions later. I recommend starting with Jujutsu Kaisen!!!!!!! There will also be other series, such as Free!, Bungo Stray Dogs, Monthly Girls’ Nozaki-kun, and more. A big mash-up. The magic is from Harry Potter, but I’m only borrowing the setting. It will appear only in the background. Later in the Jujutsu Kaisen storyline, Geto gets kicked out, Haibara dies, and the protagonist is there, so nothing can go wrong. The early story follows The Prince of Tennis. I’m a huge Rikkai fan, so the Emperor stays safe and Rikkai wins three consecutive championships. Serious synopsis: Is transmigration a coincidence or a certainty? Not-so-serious synopsis: Yu Yu’s daily life: fighting monsters, playing tennis, and working for evil capitalists.
