Class 1-A (and class 1-B if your oc is in class 1-B) was heading out to a training facility called the USJ, which they were then greeted by the pro rescue hero, 13. Her and Aizawa explained that they're going to be doing a rescue mission for each different scenario. They were about to start, when... Villains started to come out of a portal!

What is going on?! (I'm a lil lazy, surry :p)
