The gym is in disarray. Blood is splattered across the walls. Fresh. Most of the equipment is knocked over, and the equipment room is open. A few bodies lay scattered around. One of them looks suspiciously close to the coach, who you've never met, but he's easy enough to identify by his coach's whistle. There don't appear to be any zombies in the room, but... Misa has a bad feeling about this.
"Check the storage for anything useful. Hopefully no one's taken the fencing swords yet."
Meanwhile, Misa uses her incredible foraging prowess to snatch the coach's whistle. Misa equipped the coach's whistle. Couldn't hurt.
Crap. Good thing you've been holding a knife this whole time. As the zombie gets closer, you stab it in the face. Ineffective, but you panicked.
"AYyeahh!" Misa yells. She stabs the knife around her aimlessly, hitting absolutely nothing. God save you.
