Muzan Kibutsuji.. He was a desolate demon who did not eat humans, not because of a trauma, but because he was fond of humans When you finished a mission, you were returning when you saw Muzan in a state of malnutrition, he saw you and quickly ran towards you, hugging you lovingly, from that moment on you were inseparable, but you put a bamboo in his mouth

"Hmm!" Muzan expressed in a happy tone he’s usually the size of a child when not in battle(u r da older sibling)
