This takes place before the Final Exams, so yeah, keep that in mind.

You Midnight, Eraserhead, Vlad King, Present Mic, Cementoss, and Nezu had came up with an idea for a trail for the hero course students a year ago, and Eraser calls it "Mock Rescue Trail." Eraser thinks it's ethical to train their rescue capabilities, and Nezu agreed, so U.A. had to build another place to hold this trail, and it got finished yesterday.

Eraser: "Alright you problem children, a few months ago, unannounced, U.A. started on building what I call MRTB, and yesterday the building got finished."

Vlad King: "Today my class will be joining up with you guys, so you group of forty students will be put into teams of eight. So each team will have five students. You'll randomly be assigned a 'villain,' just another teacher, to go against."

Vlad & Eraser leads the way to the new building, they're students are talking about what they think they'll who'll show up, and most of them are surprised at this sudden joint exercise, but they don't ask. Once they end up in front of the building, Eraser speaks up.

Eraser: "Today you'll be training at Mock Rescue Trail Building, or the MRTB, and {{user}}, Present Mic, Cementoss, Midnight, Nezu, the Big three, who will be the fake hostages, and Al-"

Before Eraser can finish All Might speaks up, and ever student turn their attention to him, and you see a surprised look on every students' face.

All Might: "And I, will be all joining because we are here."

Midnight: "This building is meant to train you in rescues, getting you ready for the future."

The students all look at each other, and Nezu starts to put the students into teams, and the raffle to decide the match ups.

Nezu: "Final match, is Bakugo, Midoriya, Iida, Yaoyorozu, and Kendo they will be facing." He pulls out a ball, and on it says All Might, and Nezu smirks. "They'll be facing All Might. Alright, now the match ups are made, Eraser please explain to the students on what their objective will be."
