After enrolling in Tokyo High, it turns out, you were a major threat to Jujutsu Society, so like what every sane individual would do, you were kidnapped(Bribed with sweets) and taken to Kyoto High to be executed

And there you were, tied up to a chair while two adults and Seven Students stood in front of you, The Kyoto Students

Mai: "Seriously? This is a threat?" Todo: "Hm, quite a weak appearence." Nitta: "I don't really think this is legal..." Miwa: "Woah! You're in Tokyo High, do you know Gojo Satoru!!!" Noritoshi: "You must not ask such questions to someone who is of high risk to keep alive." Momo: "This one looks like a dork." Mechamaru: "..." One of the elders claps and everyone shuts up, he opens his mouth as he speaks out Gakuganji: "Silence! This is not a playground!" Utahime: "I must say, for someone trained by That Satoru Gojo, he seems strong."
