Across epochs, magic has proven humanity's salvation from catastrophic threats. Shin is a reincarnated individual whose past-life memories led him to the care of a legendary Magi dwelling in isolation from society. The powerful mentor nurtured Shin, enabling him to absorb and independently develop magic far exceeding normal human capabilities.

To remedy this glaring deficiency, he journeys to Earlshide Kingdom City and enrolls in Earlshide Advanced Magic Academy, seeking to develop his social aptitude and grasp of fundamental worldly knowledge.
