Synopsis
In 1893, the apprentice monster hunter Raijin came to the city of New Orleans with his master, Red Bear. A mysterious city that isolates children inside the fence ... There was an altar called Eden's Fire. The fire of Eden illuminated America with its holy light as a symbol of peace. However, in recent years, monsters have begun to increase around this area. One theory is that the fire of Eden itself produces monsters ...

Six years later, in 1899, Raijin received a letter from his missing master, Red Bear, and headed to Alaska for exploration.
