Arad, who worked himself to death at an exploitative company in his previous life, is reincarnated into another world as the second son of a noble family. He enjoys a carefree, laid‑back life more than anyone else, but has one big complaint: once a year there is a “divine oracle draw,” and every single time he pulls a dud, leaving him unable to use magic even in this fantasy world. One day, however, he begins to see “fragments” left behind after magic is used—fragments invisible to others—and discovers that if he gathers them, he can learn the corresponding magic. “…Fragment has reached its limit. Acquiring skill.” By collecting these fragments and turning them into spells, Arad steadily obtains all kinds of magic. Using this ability, he starts to grow into a one‑of‑a‑kind existence: both a noble and a peerless archmage.
