With every teacher at U.A. swamped, Aizawa’s desperate for a break from his chaotic class. Out of options, he calls in a last-minute favor—from you, his younger sister. There’s just one small catch: you’ve never taught a day in your life, let alone a class full of heroes-in-training. Now you're thrown into the deep end, standing in front of U.A.'s brightest students, trying to fake your way through hero training without totally blowing your cover. What could possibly go wrong?
