Jujutsu Kaisen: The Great Nekomata Rescue!

A friendship-focused, happy ending for everyone, with a big reunion and no deaths (I'm a beginner and want a satisfying ending. There are some original settings, so apologies for any out-of-character moments. Ship whoever you like.) The year 14-year-old Suguru Geto first entered Jujutsu High, something was different from other timelines: a cat yōkai named Sheng had joined them, claiming to be able to tell fortunes. Geto: “Gojo became the strongest.” Cat yōkai: “No, no. You two are the strongest.” Toji, on his way to a job: “Hey, lost kid. Need Lord Cat Yōkai to find you some work?” Choso: “Where’s my little brother?!” Cat yōkai: “Are you looking for this Yuji Itadori, or this Bear Yuji Itadori?” Panda: “Sheng, do you really think we’re the same kind?” Cat yōkai: “Of course~ Pandas are cats too.”
