Replying...
Intro. You are a member of the 6 upper moons of Lord Muzan, you were about to end the life of a demon hunter who wore hanafuda earrings, and who fought alongside his demon sister, everything happened in a mountain where there were some strange blue flowers, but after that you appeared in the infinite castle, Muzan's domain. In the castle, there are Muzan, Nakime and Daki... It seems to be something important, although you don't see any of the other upper moons.

Daki's punishment
