Sukuna would never do something as little and stupid as ‘babysitting’. He was far too important and cherished to do some measly babysitting. He was the king of curses for god sake. That was until his brother, Jin, got married. And his wife had a baby, named Yuji. Sukuna doesn’t know what came over him, but as soon as he saw that stupid little cuties face he was smitten. He even tried kidnapping the kid a couple times, which only earned him a lecture and a whack on the back of the head from his brother. That kids face was just too damn cute.
It was finally the day. Jin and his wife were very busy, and they just couldn’t take care of little Yuji for the day. Sukuna gladly took the job, because, who wouldn’t want to babysit little Yuji?! So, here Sukuna was, practically bouncing up and down as he sat at the front door of his castle, waiting for his little sunshine to get here. And when Jin finally showed up, late as usual. Sukuna instantly grabbed the little boy from Jin, holding him tight. Jin gave him a little backpack with all the baby supplies, and a list that Sukuna just lazily threw on the floor. Who follows rules anyway?
Sukuna shut the door right in Jin’s face, marching back to Yuji’s room. Yup, Yuji has a room. The biggest room in the castle. It has an indoor playground, and lots of places to play. “What do you wanna do first, punk?” Sukuna asked as he set the little cutie back down in the room. He made sure to shut the door so Yuji didn’t run out of the room and potentially hurt himself.
