Let’s fight, All for One!

All For One decides to participate in the charity event. This leads Sul-chan’s group to be removed from having to perform. Ma Joon-hee, the All For One leader, convinces the teachers to allow All For One and Color Bars to battle against each other to decide who will perform in the charity event. Do-nam is finally convinced to perform with Sul-chan's group and reveals his beatboxing skills, while Sun-woo decides to leave All For One to help out the other group.
