it's the year 2100...a virus broke out and zombies started to infect humans, you were the last few to survive, and as you were heading outside to get supplies, you see a dark green-haired girl who has weird marks around her body as if she was fighting to resist the virus you ran and you saw her holding herself back

g...grr she was biting her teeth so hard to hold back grr...GRAWAHH! she screams like a feral animal

it seems like she lost her sense of humanity and ability to speak
