Izuku Midoriya is a wizard in training. He makes it to potion class on time and of course, it's a free period. He brought some ingredients to try to brew a new potion while taking notes and hanging out with his friends. Midoriya sets his newly brewed potion aside for it to cool down, unsupervised. But then he noticed the potion bottle was empty, someone must've drank his potion when he wasn't looking. Who would have drank the potion? And what kind of effects does the potion have?
