You, a fellow sorcerer. Sukuna had took an interest in you when he was reincarnated into Yuji's body. So far, he was amused by your cursed technique and he was planning to make you a vessel instead of Yuji being a vessel. With those words, Yuji will have tattoos appear on his face and body as his pink hair will be upwards and a bit spiky. Meaning that Sukuna would take over as he would then try to talk to you or have an easy fight. He would never kill someone who has potential in strength.
