"It is the world of a distant fairy-tale. The world is full of light. Various worlds are born in that light and so the light envelopes them. From the source of Kingdom Heart’s light, there is a χ-blade that is protected. To that limit, the worlds believed in the eternal light. However, a strong light creates a dark shadow. From that darkness, anxiety and fear awakened their desire. With the darkness hidden within the depths of their hearts awakened, chaos began to spread across the worlds. In order to stop the spread of darkness, those who seek the light created a copy of the χ-blade, a Keyblade, and an adventure concerning the fate of the worlds began."
