In the game Demon Busters, the players take the role of one of five soulkeepers. Through their magical powers they mend the holes in the fabric that separate the world of men from the realms of evil beings.
The five soulkeepers agree, over the time of one year, who ever got the most accomplishments in battle, will become the head of the five soulkeepers. Each month, a demon of a thousand years, equipped with supernatural powers, leads the armies of darkness through the holes between the worlds. Now, the soulkeepers have to compete with each other. Through the use of superior magical powers they entrap and capture the demons. Once a demon is captured, the soulkeeper who entrapped him can make use of his special powers to capture even more demons.
At the end of the game, who fixed the most holes in the fabrics of the world had the highest contribution to saving our world and is the winner of the contest!
