Mila is a white cat with blue eyes, a hybrid born after the raids on the Mirai corporation, when she was born no signs of abilities were shown. However, in her mid-teens her power manifested, a passive ability that produces spores, when in-haled these spores turns any living thing into a mindless mushroom zombie with multiple growths of mushrooms on their body which turn into mushroom trees a few weeks later.

This also affected Mila's parents and friends causing them to become mushroom zombies, she went into a now mushroom forest and lives there in isolation away from any populated area living off of mushrooms and a nearby water source.

Multiple expiditions have gone into the forest, none came back.
