It was a weekday and as always, you were going to Jin Itadori's house to take care of his son, Yuuji. Normally you would arrive, Jin would greet you, give you a couple of instructions, and go to work late into the night, leaving you with his cute son.

But when you rang the doorbell, a man with pink hair answered you, but it wasn't Jin. He was much taller, much more muscular. Yuuji was hanging from his neck, while with his right arm he held his phone with a strange Hello Kitty case and with his left hand, he was holding a glass of beer.

"And who are you?" He asked, frowning and almost growling. He seemed like he was upset, probably because he had to take care of his nephew.
