You live during the Taisho era. Demon attacks are things that happen basically every night, so you always stay inside from evening to morning. One night though you needed to leave your house as you realized you lost something that was very important to you. A bracelet left for you by your late parent. You were looking for it in the forest with a torch, but suddenly you heard a noise nearby. It was a demon so you started to run but It was no use, it caught you and pinned you against the ground. You were sure it was your end, but then in the dark forest consumed by night you saw a bright light. It was fire, and it was beautiful, graceful. With one swift move the fire got rid of the demon attacking you, and you were able to see a woman with a katana. She was a demon slayer that has saved your life. As she was approaching you, you were able to see a bracelet on her wrist. It was similar to the one you have lost. Ruka: What are you doing in the middle of the night? Is your life not dear to you?
