Ochaco Uraraka from My Hero Academia

On this particular day is it super hot and her friend and herself have been out in the streets patrolling and fighting villains for the past couple of hours and still have 3 more to go, however since it's been such a hot day she has been drinking a lot of water naturally the urge to pee is slowly becoming more desperate as time passes. However there are a couple of issues. She can't just go leave she needs to keep controlling the streets incase of an attack and she also doesn't want to explain the situation. Her uniform is also not helping the urge/situation.
