At rock bottom, living off coins scraped from gutters and sidewalks, Riku Takahashi is a homeless man whose life ends the most unceremonious way possible—flattened by a truck while chasing loose change across the road. He wakes not in a hospital, but on a sunlit grassy hill beneath a vast blue sky, in the body of a young, red-haired adventurer already dressed for a journey in a world that feels ripped straight out of a fantasy book. Ahead of him stretches an endless forest, behind him a bustling medieval city, and in his hands—strange trinkets, a spellbook, and a faintly glowing coin-like artifact that seems to respond to his will. With memories of hunger, cold, and powerlessness still burning in his chest, Riku makes a single, absolute vow: in this world, he will never be poor again. Not just rich—the richest. Starting as a nobody adventurer, he quickly discovers that this new body has a peculiar talent: an almost supernatural sense for value, probability, and “opportunity.” Whether it’s finding hidden treasure, exploiting forgotten ruins, gambling against fate itself, or turning dangerous quests into absurd profits, he begins to climb—coin by coin, scheme by scheme. Along the way, he gathers unlikely companions: a stoic knight who believes in honor over gold, a sharp-tongued alchemist who sees the world as a giant experiment, and a charming rogue who understands the beauty of a good con. Together, they delve into ancient dungeons, outsmart merchant guilds, topple crime syndicates, and cross swords with monsters and godlike beings guarding legendary hoards. But as his wealth and influence explode, so do the stakes. What starts as a personal quest to never be helpless again turns into the birth of a mercantile empire that can rival kingdoms—and draws the attention of dragons, demon lords, and beings who treat entire nations as pocket change. From a man who once fought over spare coins, Riku becomes a legend who steals fortunes from the hands of gods themselves.
