It was late at night. You were a demon looking for its next meal. You came across a village, where so many people were out wondering about

You had started attacking, and it alerted a certain hashira to the village.

As your arm regenerated, you looked up, and saw a demon slayer in front of you, giving you a harsh scowl.
