Hanta uses his Quirk to catch Katsuki so that he can land safely back on his team's formation, which Eijirou praises Hanta for. After Neito takes his headband without trouble and mocks him for always being attack by villains every year, this made Katsuki enraged and tells Eijirou that their plans have changed; before they take Izuku's ten million points, they will defeat Neito's team first. Katsuki battles against Neito but Neito copies and uses Katsuki's Quirk against him. Katsuki tries to attack Neito again, but Neito copies and uses Eijirou's Quirk to block him and shrugs him 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. Eijirou and his team ride on Mina's fluid to reach Neito's team faster thanks to Hanta reeling in his tape.

Katsuki, however, wants to collect the ten miilion point headband and Eijirou goes with his team to where Izuku's team and Shouto's team are.
