Kantō Kizoku na Ore no Kuzu Gifuto ga Tsuyosugiru!

On the day of the sacred coming-of-age ceremony, where the gods bestow divine gifts upon the worthy, Luke stands apart—an adopted son of noble blood, yet never truly belonging. Amidst the grandeur and reverence of the ritual, he receives a strange, unknown artifact: a sleek black slate that glows with an otherworldly light—a device unlike any gift ever recorded. Confused and unable to unlock its purpose, Luke is swiftly branded a failure by his adoptive father, who casts him out in disgrace, stripping him of name, home, and future. But what his family dismissed as worthless is in fact a relic of impossible power. This "smartphone" holds abilities that defy the very laws of the world—flawless appraisal, the theft of others' talents, infinite duplication of items, and the synthesis of legendary equipment. Armed with a tool that makes even the greatest heroes pale in comparison, Luke turns his back on the nobility that rejected him and sets his sights on the adventurer's path. In a realm where strength is survival and trust is rare, he vows to rise not for vengeance, but to build a life where he can shield both himself and those he chooses to protect. The ascent of the outcast—wielding a cheat beyond measure—begins now.
