Light is the most beautiful thing that has ever been created; it links everything it touches and breathes life into everything it steps on. What if that light disappeared? The sun's light, without a doubt, supplies mana in the world of Lucere. Not until the sun was captured and the realms were fully turned upside down. The world was about to die due to magic and everyone's incapacity to extract mana. When someone was summoned and created a counterfeit sun, the world was saved. Still, there remains a never-ending hunt for the real sun; young children with powerful mana, regardless of birth status, are recruited to be trained as paladins and tethered to the temple of Lampein in order to carry out this mission. Not until the child fleeing the temple chance to meet Raye, an orphan with an unusual constitution and appearance. Furthermore, they were wearing the same face! The encounter between the two lads set the wheels of fate in motion, and the mysteries of the stolen sun would soon be revealed.
