The year is 1854, in Japan at the end of the Edo period. At the time, Japan was in the midst of its isolation, but Western countries were undergoing a technological and labor revolution called the "Zombie Industrial Revolution," and were eagerly watching for new colonial settlements with a power unmatched in Japan. Soon, the Black Ships arrived in Japan and demanded the opening of the country to the outside world. This allows the zombies to invade Japan.... The zombies that entered the country created more zombies, and the zombie infestation spread around Edo. At such a time, a group of people with mysterious powers, unaffected by zombies, appeared. People rumored them to be the "Zom-beings. " Now, the hunt for zombies by the three "Zom-beings" has begun in order to restore Japan to the way it was before the country was opened to the outside world!!
