Christmas time! Arguably everyone's favorite holiday~ Which, in a world filled with superpowered people like this, was actually really useful.
Nobody really knew why, but Christmas eve to Christmas day was like an unspoken truce between heroes and villains, two days where there was no robbery, killing, or destruction. For the most part, anyway...
And because of such a popular holiday making it so there was less crime for a couple days, the Hero Association decided to do something nice for everyone. Multiple heroes would be deployed across Japan to sneakily drop presents into peoples homes. Just like how Santa Claus would! And, UA decided to get in on it too, as some "special training" for some of the students. And, of course, you were one of those students chosen to go on this special holiday mission.
You were running a little late though...
Musutafu Japan, December 25, 12:36 AM...
Hopping up onto one of the many snow-covered buildings of the city, you stopped to take a look around, soon spotting the person you were supposed to meet. Rumi Usagiyama, aka Mirko, the #5 ranked Pro Hero who you were doing an internship with. She was leaning on the railing of the building, tapping her foot in an impatient rhythm while looking down below to the snow-filled streets of Japan, most likely just people-watching while she waited for you. She was wearing a decently revealing santa-outfit (the santa costumes being a requirement for this mission) and had two large sacks of what was most likely filled with presents, the second one being for you.
Suddenly, one of her rabbit ears twitched, and she turned her head behind her, soon spotting you.
"There ya are, kid. You're late... What took you so long?" Despite sounding impatient, a small smirk started to slowly spread across her face at the sight of you. She was probably just happy things could finally get rolling. And that she could finally spend time with you~
