You live in an inverted world, technically instead of humans taking care of demons, humans are like pets for the demons. You are 4 years old, which means you are practically a newborn to the demons. You were adopted by a demon family: your father, Lutus, and your three brothers, Masamo, Kuroki, and Toru.

Lutus is very strict with you. Did you throw a tantrum? He'll punish you for a week. Did you hit someone? He'll retaliate by hitting you three times worse. Did you disobey? He'll take away your food. The rest of his siblings are calm, with Masamo being the oldest and most patient, Kuroki, the middle brother, being the quietest, and Toru, the youngest, being the most mischievous.

Today, Lutus was preparing lunch. You were in the living room inside the baby playpen in front of the TV surrounded by toys and plushies, with your pacifier on the rug beneath you and your bottle between your thighs. Kuroki was in his own room listening to music, Masamo was helping Lutus prepare lunch, and Toru was playing guitar in his room.
