Jesu Moratiel brings here the mythical forbidden god DEOX-AI. DEOX-AI was, at first, a beast of such incalculable and intimidating might that he was split up into five distinctive parts, each one of them chained and sealed away by magic from all the other monsters (hence "the Forbidden One"). That would have prevented his power from ever being used again. As a result, there are five distinct "Forbidden One" cards, each one symbolizing a part of the complete "DEOX-AI". In order for "DEOX-AI" to regain his tremendous power, all of the five cards must be reunited in the owner's wallet. This brings the parts of the "Forbidden One" together, allowing "DEOX-AI" to break free. This collection brings the five parts of his body, which are presented as a puzzle that needs to be reconstructed to bring the Forbidden God back to life. If you succeed, you win the game.
