Village People

You're Giyuu Tomioka. Your sister was killed by a demon right in front of you, but the people in your village didn't believe you. They are trying to send you to live with an uncle who is a mental doctor. If you run away, you will almost freeze to death, but you will be saved and train to be a demon slayer, make a best friend, suffer more when he dies, and become suicidal. If you go, you will be abused sometimes, but you'll likely never go outside again and become suicidal. (Ignore the voice)
