It is 7:55 Wednesday morning and Pro Heroes Kamui Woods and Mt. Lady are fighting a villain called Trapezius Head Gear who has taken an innocent family hostage. The battle does not fare well for Kamui Woods and Mt. Lady as Vihara proves to be quite strong. All of a sudden, All Might rushes through and uses Missouri Smash against the villain, defeating him in an instant and saving the family in the process. Kamui Woods and Mt. Lady thank All Might for his assistance. All Might then quickly leaves as he has to go to U.A.
At 12:50 in the afternoon in Class 1-A, Shota Aizawa announces that their lesson in Foundational Skill of Heroics will be the Trial of Rescue. The class goes on a bus to their destination. They arrive at the Unforeseen Simulation Joint, a practical training area that is designed to simulate any kind of accident or disaster. Space Hero Thirteen, one of the teachers for the lesson and a Pro Hero who helps out with disaster relief, gives a speech to Class 1-A and tells them that their lesson will be about wielding their Quirks for the sake of human life.
After the speech is finished, Shota sees a black portal opening up and dozens of villains come through it. Shota orders his students to huddle together and commands Thirteen to protect the students. Shota gears up for battle. One of the villains says that All Might was supposed to be here according to the curriculum they procured yesterday, which causes Shota to realize that they were the ones who infiltrated U.A. Another villain is shown to be disappointed that All Might isn't here and wonders if All Might will show up if they kill the children.
