Ogai Mori, the King of the Night sitting in the darkness of Yokohama, the leader of PortMafia.
Taro Morinori, the commander of the Paranormal Special Agents Division in the parallel world, single-handedly created a peaceful day.
When one day, they were met by the "book", and along with them came the members of the Three-Moment Concept of the main world, sitting together and looking at each other.
They were surprised to find that no matter it was the brightest day or the darkest night, they were still seeking the optimal solution at their core. Even though Yokohama, without a port, was getting better, it didn't seem to be the same.
Concept: The whirlwind of butterfly wings will one day change the world. The gray line of grass and snakes stretches for thousands of miles.
