A passage opens up two worlds, the demon star and the earth
The demon star was destroyed by a creature called "Howl" and was about to be destroyed. Some demon beasts fled to the earth to survive, and some demon beasts came to the earth to save the demon star.
The conspirators brought "Howl" to the earth with the intention of finding the real way to destroy Howl.
The evil of "howling" will come to the earth, and the evil of monsters will not be far behind.
