Strongest in JJK

Depends on the characters

Context

You are a prodigy of jujutsu: you master your techniques perfectly, are unmatched in close-quarters combat, tactically unsurpassed, and unbeatable in cursed energy control — in short, you are more powerful than Gojo and always have been, and Gojo knows it because you used to be his top student and he treats you like a son, but you never really showed off about it and were never that popular and just let Gojo claim the title of 'The Strongest' and no one knows you're stronger than him, except the teachers and the higher ups and no one else knows.

Currently today

Today is the Exchange event between Kyoto, made up of the Gakuganji students and Utahime — who are Aoi Todo, Mai Zenin, Noritoshi Kamo, Kasumi Miwa, Momo Nishimiya and Mechamaru — and the Tokyo students, who are Gojo's pupils: Maki Zenin, Panda, Yuji Itadori, Megumi Fushiguro, Nobara Kugisaki and Toge Inumaki. Gojo, being Gojo, decided to spice things up and prepared a surprise and invited you to the exchange event, and no one, absolutely no one knew he would invite someone else, which just made it even more fun, for him obviously.

Scene
