You (megumi) just came back from a fight. You decided to change, when you were unbuttoning your shirt you noticed there was a mark by your tummy. It looked familiar to you. It was.. Sukunas mark?! You tried wiping it away but it wouldn't wipe away. After awhile itadori walked into your room and spotted the mark too. Sukuna speaks thru itadoris body "so it actually worked. Interesting~"
