Hanta manages to place 8th in the Obstacle Race, allowing him to participate in the next event, the Human Cavalry Battle. He teams up with Katsuki along with Eijiro and Mina.

After the Human Cavalry Battle begins, Katsuki jumps into the air and tries to attack Izuku with an Explosion, but Fumikage uses his Dark Shadow to block it. Hanta uses his Quirk to catch Katsuki so that he can land safely back on his team's formation, which Eijiro praises Hanta for. After Neito takes his headband without trouble and mocks him for always being attacked by villains every year, Katsuki states that they will beat them first before going after Izuku.

Hanta and his team continue to battle Neito, who manages to rebuke their efforts. However, Katsuki eventually manages to grab two of Neito's headbands and Hanta uses his tape to grab Katsuki to reel him back onto the formation, with Hanta complaining that Katsuki did not warn them when he is about to jump off. However, Katsuki still wants more points and orders his team to attack; having Hanta use his Quirk and has Mina use her dissolving fluid.

Katsuki, however, wants to collect the ten million point headband and Hanta goes with his team to where Izuku's team and Shoto's team are.

Hanta steps into the ring to face his opponent which is Shoto. After the match begins, Hanta confesses that he doesn't know if he has a chance but states that he won't simply roll over. Hanta makes the first move, wrapping his tape around Shoto, attempting to throw Shoto out of the ring.

However, Shoto retaliates by using Giant Ice Ridge, creating a huge ice glacier that freezes the majority of Hanta's body and causes Hanta's tape to crack into pieces, which frees Shoto. Midnight asks Hanta whether he can move or not, to which Hanta replies in agony that he can't move. As a result, because he is unable to move and unable to do anything, Hanta is declared defeated and is eliminated as a result. The audience tells Hanta to not mind his loss. Shoto goes to Hanta, apologizing to him for overdoing it and then melts the ice off of him with his fire power.

Soon, Shota enters the classroom and informs Class 1-A that all of them are going to the forest lodge which will be a boot camp; the students who failed are happy and relieved. However, Shota reveals that Hanta also failed the practical test due to being asleep the entire time and as a result, Hanta will be receiving harsher training at the boot camp.
