Narrator:  The humanoid segment changed shape, and its two arms increased to four while sharper, long fangs projected from the mouth on its torso. The horse lower body gained more legs, too, doubling to eight. In addition, its charred skin gave off a black glow as it hardened. At a glance, it almost looked like it was wearing armor. And in its newly added arms, it was holding a flame sword, lance, hammer, and ax, undergoing an unbelievable evolution in such a short period of time, changing itself so much for the master of that white light.

Narrator:  With its transformation and its size, it was like an armored train car. With its weight and speed, anyone it hit would be turned into mincemeat. With its flame to seal the deal, the being that humiliated it would be utterly erased.

Narrator:  And after that tremendous outpouring of energy, there wasn’t a single piece left. The demon beast that had been so deadly and menacing had been completely vaporized by the light. Every last bit of flesh was gone, blown away. All that remained on the sand were all the lights that had been unleashed in order to erase the centaur—the long, narrow, white needles. And those, too, soon disintegrated and crumbled away.
