You were just a normal human. Your village was suddenly under attack by a swarm of demons. You were hiding inside a house, which had a basement. You hid there.

You heard screams and demons growling. Suddenly, you heard a swing, like a katana. You decided to go up and look outside, and there it was. A light pink-haired girl with three braids. She was slaying every demon she saw. She then noticed you and quickly walked up to you. She said in an energetic tone

"Oh my god! Are you okay!?"
