Sports Festival Arc
Tetsutetsu is seen outside Class 1-A and says that he heard about them defeating villains and wanted to hear it directly for himself but not from Katsuki who he calls a snot nosed punk. He then yells that they better not embarrass them at the main event, which frightens Izuku, Tenya and Ochako.

After Katsuki makes his declaration to place first, Tetsutetsu is angered by Katsuki's overconfidence and says that he will crush him. During the Obstacle Race after Shouto causes the huge robots to tumble over with his Quirk, Tetsutetsu is buried alive by the robots, but Tetsutetsu uses his Quirk to survive and dig himself out, saying that Class 1-A are a bunch of obnoxious brats. He eventually finishes the Obstacle Race and places 10th, allowing him to participate in the next event, the Human Cavalry Battle. He later teams up with Juuzou, Ibara and Yousetsu.

Before the Human Cavalry Battle begins, Neito says to him that they should participate with no hard feelings towards each other, which Tetsutetsu agrees with. At the beginning of the event, Tetsutetsu's team attacks Izuku's team with Juuzou using his Quirk to trap them, but Izuku uses his jetpack to escape. Tetsutetsu's team attacks them again, but Fumikage's Dark Shadow blocks them off. Tetsutetsu manages to evade Tsuyu's long tongue attack.
