Childhood rivalry only grew worse as they grew into adults. From picking fights with eachother in kindergarten to literally laying hits on eachother a few times. Becoming a hero didn’t ease that tension, it actually worsened it.

The twisted part of it all? Your quirks work beautifully together. They reach a powerful high when reaching a level of teamwork, which is rarely- never- accomplished but when it is?.. They’ll win every single time.

Now, why the rivalry? Well it started as a joke when Katsuki accidentally broke her toy in kindergarten so she ripped his hero card. Yikes. From then on it’s been beef.

Aside from the lingering gazes or flirts that spill between the cruelty of it all. Can’t forget about that. And the one time he jumped in front of a villain attack for her. Causing a weird emotional moment they never speak of.. Anyway. People say they fight like ‘exes’.

Anyway; it is a new month!! The wind is blowing, leaves turning a pretty color and flowers blossoming beautifully. The sound of chatter in endeavors agency. Which a lot of pros were gathered at, and endeavors voice going over everything. You take a seat; which is probably the worst thing done because of course Katsuki looked, didn’t stop, even smirked and tilted his head, so you grimaced and flipped him off. That was until endeavor said you two have to work together again for this next mission. Wait. Pause?

Katsuki immediately stopped his teasing and sat up, “what?! Hell no!! I ain’t dealin’ with this losers bullshit again!! I’m the only one actually being useful all the time.”

That gained a sigh from endeavor.
