Nioh Doesn't Want an Out-of-the-Ordinary Life

It's finished! This was my first time writing a story, so the plot and writing have plenty of issues. I hope you'll bear with me. Thank you all for your support and suggestions! A strange trip to another world in his first year of middle school earned Niou a Hydro Vision. After returning home with the Traveler's help, he found that the world looked completely different. The waypoints were right, and the people were the same as before he got lost, but now there were all these hideous curses. Niou sighed. He couldn't just ignore those filthy things, so he began clearing the curses from the area around Rikkai as a volunteer. A trip to the aquarium with the tennis club, and the display tanks break. A trip to Tokyo to buy tennis gear, and he runs into a crime scene. Niou Masaharu: Puri. What do you mean the jujutsu world wants me to attend Jujutsu High in high school? No way! I want to play tennis with Yukimura in high school, too. Holding onto Venti, who'd crossed worlds to visit, Niou asked, "Why did I come back from Teyvat with so many weird people and strange things around me?" Venti: "Ehe." Life is full and happy with tennis and kyudo practice. Niou says the jujutsu world, magicians, and walking death gods can all stay away from him. Rikkai's three consecutive national championships matter most! About the pairing: It will definitely be Yukimura and Niou, but romance will take up very little of the story, because I've never dated anyone (. There are also brief mentions of Di Fei and Xia Wu Xiao as friends. [Reader's Guide] 1. First time writing. This is basically to fulfill my own youthful dream, and all the OOC is mine. 2. Rikkai wins the Kanto title sixteen times in a row and the national title three times in a row. 3. I'll try to balance the supernatural elements and tennis. There will be identity reveals. 4. Lots of personal additions. For example, elemental power can dispel curses, and Geto and Gojo are both teachers in this Jujutsu Kaisen alternate universe. 5. Niou has a Hydro Vision and uses a bow. He'll practice kyudo. 6. I won't deliberately make Seigaku look bad, but fans are still advised to proceed with caution? Theme: Fulfilling a dream
