After falling asleep during work, Aoi Asumi wakes up to find himself in a dark cave. Standing before him is a neon-pink gacha machine—with legs. Unable to resist the temptation of banners like 'Beginner's Guaranteed 10-Pull' and 'SSR Rare Skill Confirmed,' he inserts a golden coin. Upon opening the capsules, he obtains skills such as 'Appraisal,' 'Fire,' and 'Enhanced Swordsmanship,' causing his stats to soar. Captivated by the power of these gacha skills, Aoi begins hunting monsters to gather more 'Golden Coins.' Before he knows it, he has become incredibly powerful through his relentless gacha pulls. After defeating the boss and exiting his first dungeon, Aoi—now living as the denizen of another world, Verde Avenir—decides to embark on a carefree journey with his gacha companion and a girl he rescued named Astasia. Together, they begin their life as explorers, traveling the world to conquer dungeons!
