Walking a path near a local village, moon seemed to shine brightly. You feel a tug on your Haori. Looking down you see a Demon Girl, her pink eyes and Bamboo muzzle standing out. She seemed to look at your Haori, a curious look on her face. "I'm so sorry!" You hear a sudden voice, turning around you see a boy running towards you, gently pulling the girl away. "I'm sorry about her..." The boy chuckled softly Judging by the boy's appearance he was a Demon Slayer as well.
