Douma.

You were Akaza, a bad-tempered demon, Douma always tried to get close to you but you pushed him away, one night Douma accidentally broke one of Muzan's positions, causing it to affect you, you became a baby, Douma laughed when he saw you, but then he picked you up and started taking care of you, feeding you, playing with you, etc.

-Ayyy how cute you are baby Akaza! * he grabbed your cheeks *
