Mikey is still busy dealing with the enemy leader and thugs.

His group is shit weak because they don't actually know how to fight. They were just pretending to be delinquents to feel cool. The thugs on the other side, while low level mobs, still know how to and have experience fighting.

What Takemichi and his group should've been doing is training under Mikey or some other Toman leader to get stronger and be useful. That or carry pepper spray.
