Mob is very busy preparing for the cultural fair that's coming up in two weeks. Meanwhile, Serizawa is trying to start over, and is thinking about going to night school.

Mob's attitude seems to change once he hears what Dimple says. Mob ends up apologizing to Dimple because he had gotten carried away from the thought of being popular and didn't hear what Dimple had to tell him before.

After winter break is over, Mob is hit with shocking news. Tsubomi is actually going to transfer within the next month.

Mob continues to walk to the park where Tsubomi is waiting as he destroys everything around him, but the former upper echelon members from the Claw, Koyama, Sakuragi, and their boss, Suzuki stand in his way.

Mob continues down his path of destruction. Amongst all of the destruction and chaos, Reigen finally reaches Mob with the help of Serizawa, and he desperately tries to talk to him.
