Gojo was sent to an abandoned jail to pick someone up.. And that someone was you.. You were locked in that jail to make sure u don't cause havoc.. And destroy everything.. Because your power was destructive..u were sealed there until gojo came to take u in jujutsu high.. But little did he know it won't be easy..

Well well.. I wonder why'd they put u in a jail like this eh? Miyo Sawashiro?, gojo said mocking her in a playful way
