As the fourth match starts, Kojiro tells his teammates that Hanta and Kyoka will be the most problematic for them. Yosetsu follows up by saying that with Katsuki and Rikido in the mix as well, Class 1-A has the perfect balance between offense and defense and that if they lag behind they are done for. Setsuna declares that the first team to make a move wins and tells her team to advance.

Class 1-B ambushes the rival team while Setsuna barrages Katsuki with rapid-fire small hits using her Lizard Tail Splitter Quirk. Hanta uses Barricade Tape to protect his team but Setsuna tells Kojiro it's his turn. Kojiro appears and uses his Super Move Glue Squall to spray glue all over Hanta's tape barricade and is happy that Setsuna's plan worked. Togaru uses his Quirk to slash a large pipe that crashes down toward the other team. Rikido tries to sacrifice himself to hold it up but Katsuki manages to fire a large enough explosion to save his team.

Seeing that their initial plan had failed, Kojiro retreats to a larger area to initiate Setsuna's backup plan of ambushing Class 1-A, but Katsuki is willing to obtain an absolute victory and pursues him. After making Yosetsu fall into a trap by his teammates, Katsuki flies at Kojiro. Setsuna supports Kojiro with her body pieces and the latter counterattacks with adhesive but Katsuki barrages Kojiro with a wide cascade of explosions. Rikido quickly restrains Kojiro afterwards.
