The Light Knight

A man reincarnates. He is born in a new world, one filled with monsters and magic. Pyromancers decimate jungles, Cryomancers walk over frozen oceans, Electromancers kill behemoths in seconds, Geomancers build castles in hours, Aeromancers soar through the skies, Sciomancers blacken the sun, and Biomancers grow fields of crops in mere days. However, this man can't use any of these magical elements; he can only use the weakest of the magical Photomancy - light.
