Itadori’s father, Jin, had hired you to babysit little Yuji Itadori a few months ago. At first, you thought it would be a simple side job, something to fill your weekends. But Yuji turned out to be the easiest kid you had ever met in your entire life. He was loud, sure. Chaotic, absolutely. But he was also the sweetest, most affectionate little boy who would run to you with open arms and excitedly ramble about whatever was happening inside his little brain that day.

So when Jin called you one night asking if you could babysit again, you answered without hesitation. You were already reaching for your bag when he added something strange, something that made you pause mid-motion.

“Oh and Yuji’s uncle is there too. Try to not piss him off.”

You blinked, confused, your hand still hovering over your things. “…His what?”

But Jin didn’t let you finish. The line went dead. He hung up. You stared at your phone like it had personally betrayed you. Yuji had an uncle? Jin had a brother? Since when? And what kind of warning was that? Try to not piss him off? What was he, some sort of wild animal?

Still, you had already agreed, so you got dressed quickly, threw your hair up, grabbed your jacket, and called an Uber. The whole ride, the driver kept glancing at you through the rearview mirror because you looked like you were preparing for a job interview mixed with a funeral.

When you arrived at the Itadori residence, everything looked normal. The porch light was on. The house was quiet. Nothing suspicious. You walked up the steps, took a breath, and knocked on the door like you always did. Usually, this was the part where Yuji would come running at full speed, slide across the floor like a penguin, and nearly crash into your legs while greeting you.

But this time… nothing.

Instead, the door opened slowly, and standing there was not your favorite little sunshine, but a tall man you had never seen before. And oh boy, he was not giving “friendly uncle” at all. His aura hit you like a punch to the face. cold, sharp, and absolutely menacing. He looked at you like he was evaluating whether you were a threat or just another nuisance he had to tolerate.

His eyes moved from your shoes to your face, slow, unimpressed, and with so much pressure behind that stare you almost forgot how to breathe.

Oh.

This must be the uncle. You instantly understood what Jin meant.

Behind him, the living room was pure chaos. Toys everywhere. Noise everywhere. Yuji was in the middle of it all, wearing a cape he definitely made from a blanket, swinging a toy sword at absolutely nothing but air. He didn’t even notice you had arrived. He was deep in his tiny world of destruction and imagination.

But the uncle? Definitely noticed you.

He lifted a brow, crossing his arms, the muscles in his forearm flexing in a way that made you straighten your posture instantly.

“Who the fuck are you, woman?” he asked, voice low and edged with annoyance, as if your existence itself was mildly offensive.
