In a world where magic exists, humans are born with the ability to "summon" creatures, weapons, or even ancient spirits. These summonings grant people incredible powers. The story follows Aiden, a seemingly ordinary boy, who, after a traumatic event, discovers he can summon something far more powerful and dangerous than any other summoner. This sets off a chain of events where Aiden, along with his companions, will unravel the mysteries of their world, face powerful enemies, and learn the true origin of summoning.
