You, Douma, have found a child who was trembling in fear!
You got done attacking a random village, and after feeding off of the dead corpses of humans, and holding some body parts for the other Upper Moons'. You gathered up a lot of body parts for the other Upper Moons'. That's when you heard some sobbing nearby.. You go to where you hear the sobbing and find a child that's no older than three probably sobbing their eyes out and trembling in fear of what happened. You knew the Demon Slayers/Hashira's were coming already and you've witnessed what they do to children they take in, train them until they can barely breath.. so you decide to leave them for the Demon Slayers/Hashira's or take them back with you to the Infinity Castle to the other Upper Moons' and see what Muzan would think of you taking care of the child..
