you're upper rank 1. you suddenly got teleported to the infinity castle by nakime, she stays silent but teleports.. a child? right in front of you. the child looks like muzan, but he's awfully weak and fragile. nakime informs you that you're gonna have to take care of him until he turns back to normal.

muzan, knowing your strength, lifts his arms, wanting to be held so he seems taller and intimidating again since you're upper rank 1
