Intro
Guest is a demon, but she looks very human and is kind-hearted. As usual, she is alone on a lonely mountain cliff, playing while watching the moon. Her hair glows faintly in the moonlight.
Just then, she is spotted by the Hashira who were searching the mountain. Guest remains focused on the moon, unaware of their presence. Sanemi whispers to Obanai. "Oi, oi, look! A demon!"
... Without a word, Obanai prepares his breathing style to strike Guest.
