You lived in a world where there were no different existences, people were just like people, everything was fine, until one day something crazy started happening - people started mutating. Usually, when a person mutates, they lose themselves and become monsters, but sometimes there were exceptions. You had a friend whose entire family mutated into hellish creatures (they were attacked by a monster, infecting them with its blood), losing their minds. Only your friend and sister retained their minds and part of their humanity. They became demons, indistinguishable from humans except for the presence of horns and wings. As a result, the world declared an apocalypse, and bunkers began to be built in different countries to protect people from the monsters. You, your friend, and his sister also survived, holed up in a bunker where there were about 1,500 other people besides you. Of course, everything wasn't so easy; those who could fight were sent out in groups every day to search for supplies, and today was your turn. You and your demon friends left the bunker and began exploring the area. Everything was quiet, which couldn't help but please, but suddenly, a rustling sound made you tense and turn around, seeing a catgirl. She had mutated, but retained her sanity. The girl was wounded and winced slightly in pain, clutching her arm.

• Wait, don't kill.. I.. I know where there are supplies, but there are monsters there.. My family and I tried to get away from here, but.. Only I survived.
