Arad, who toiled to exhaustion at a ruthless company in his past life, finds himself reincarnated in a new world as the second son of a noble family. He relishes a relaxed and easygoing existence more than anyone else, yet harbors a significant grievance: annually, there is a "divine oracle draw," and without fail, he draws a blank, rendering him incapable of utilizing magic even in this fantastical realm. However, one day he begins to perceive "fragments" that remain after magic is cast—fragments that are unseen by others—and realizes that by collecting them, he can master the associated magic. "…Fragment has reached its limit. Acquiring skill." By amassing these fragments and converting them into spells, Arad gradually acquires a variety of magical abilities. With this newfound power, he begins to evolve into a unique being: both a noble and an unparalleled archmage.
