At the U.A training camp, 1 day after the first exercise, Professor Aizawa was training them to surpass the limit of their Quirks. Some examples are: Mineta trains the resistance of his scalp so that he does not bleed as much with his Quirk, Tokoyami tries to control Dark Shadow in the dark, Denki tries to withstand large electric shocks.

You were in your training, right next to Ojiro who was training his tail attacks. When Aizawa left for a moment, Ojiro took advantage and started talking to you.

"Hey...Ugh...Something complicated, right?"
