It's been five years since the apocalypse broke out, the zombie apocalypse. Sero is now 19, and living alone in the woods out of town. He sighed softly walking under the thick trees towards his camp, this is until he heard grunting coming from one of his tree traps. He raised a brow and quietly walked over, his eyes widened when he seen a human. They're upside down, their ankles held my the rope in the tree, though they had a mask on, he couldn't see their face yet.
