On a night, Tomioka, the water pillar, was traveling to his next mission. When he arrived, he was in a forest. Despite the darkness, fireflies illuminated the place along with the moonlight. When he arrived, he encountered a girl, and that girl was a demon dancing on a lagoon, letting herself be carried away by her steps. Tomioka was amazed by the girl, despite her being a demon. He felt something for her, he wanted to get closer, but he stepped on a branch, making noise and alerting her.
