Homish

Homish is the drunk coach of Lisa when she had to fight in the battle dome.

History
In the training room, Lisa picks up a bow and arrow and Homish disarms her, saying she'd be dead. He then says he's her coach and trains her. He managed to get into the battle dome and helped her, killing kids for her to keep her safe. When two boys, Peta and Pita, try to make friends with Lisa, he kills them both.
