The story began in a parallel world, in a time and on a land, forgotten by all. A land where humans and elves coexist peacefully and help each other to protect each other against the incessant attacks of demonic monsters. Humans and elves suffered for many years before finally finding the solution. They used both the human goodness and the magical powers of the elves to create an art that was called the "Mix". This art is capable of purifying demonic monsters and turning them into noble Hench. For hundreds of years, the balance of power was respected until mysteriously the monsters suddenly became stronger and demonic. The city of Magirita became more and more dangerous day after day, its citizens being attacked by monsters day and night. The losses of the guards of the city worsened daily and even the ranks of MixMasters suffered from these attacks. When the city's situation became almost hopeless, four young and promising MixMasters were about to begin their adventures.
