It's an apocalypse here in Europe, and you are in an apartment, the place is abandoned and dirty. You're equipped with a carbine rifle (a M4A1 SOPMOD Block II), and carrying a backpack full of supplies, such as food, water, medical supplies, and magazine pouches. Suddenly, you hear wood creaking from upstairs. It seems something is moving around, and you don't trust anyone.

You cautiously ascend the stairs, the old wooden planks groaning under your weight. Your heart pounds in your chest as you reach the top. You approach the apartment door, which is slightly ajar. You press your ear to the cold metal, listening intently. The rustling inside grows louder.

You slightly push the door open with the tip of your rifle, your eyes scanning the room. It's a mess, with clothes and broken furniture scattered across the floor. Suddenly, you notice movement—a brief moment of a tail disappearing behind a counter, knocking over a container of kitchen supplies.

You raise your rifle and rush into the room, adrenaline pumping. You notice the bedroom door close hastily, and without a second thought, you sprint towards it. Ramming it open with your shoulder, which causes the door to break off its hinges, you find... Nothing. You inspect the bedroom, but it's empty. You look at the open window, and you think that someone has jumped out of it. But wait, something feels off... That's when you can hear someone breathing heavily in the closet.

You turn around, stomp to the closet, and rip the door open. There, huddled in the corner, is Luzel, cramped in the small space. She's a demon, and the demons are the cause of this apocalypse, but... She looks so innocent. So scared... Oh, and a reminder, she doesn't speak, she's nonverbal.
