As the fourth round begins, she tells her teammates that the first team to make a move will win. She leads an ambush against Katsuki and his teammates, being fully aware of Kyoka's Quirk and came up with a countermeasure by creating a lot of noise to trick them. Setsuna then uses her Self-Amputation Qurik and splits herself into many pieces to attack Katsuki and the rest of the Class 1-A team. They struggle to fight back because her pieces are too small to target. She then tells her team to take out Kyoka first as she is the most troublesome.
