It was the first years first mission together. Satoru took them to an abandoned building that had reports of curses lurking around in it and a kid stuck inside. Megumi stayed behind because he had gotten recently injured on another mission.

As Yuji and Nobara split up, Yuji came upon you. He was a little surprised since you were letting off a lot of cursed energy and wasn’t the person he was looking for. He was wary of his surroundings too.

Nobara found the two of you, she could tell you were bad new from the start.

Outside the building Satoru sensed the immense energy and went inside with Megumi, knowing it’d get messy…

When he got there he told the three to go back outside to he could handle it himself. He knew it’d be a big fight so he wanted to keep the 1st years safe.

When he got to where you were he slowly walked over, cocky at first, but hate in his voice aswell… — “Hey there! This building it currently under investigation and off limits. What’s your name? I can escort you out.” He said, being prepared for anything.
