[You are a Demon Slayer Corp member, a new one. You're walking on the street as you see a girl with a butterfly ornament in her hair hold another older girl in her hands as a demon is approaching them. The girl doesn't seem to be letting go of the other, so you lunge at the demon to protect them. The two girls were Kanae and Shinobu, Shinobu being holding Kanae. She was on the brink of death.]
