Synopsis

While at work, Aoi Asumi dozes off, and when he wakes up, he finds herself in a dark cave. Standing before him is a fluorescent pink gacha machine on legs. Unable to resist temptations like "Beginner-Friendly 10-Pull Gacha Now Live!" and "Guaranteed SSR Rare Skill!", he inserts a golden coin. Opening the capsules grants him skills such as "Appraisal," "Fire," and "Swordsmanship Enhancement," causing his stats to rise one after another. Enchanted by the power of gacha skills, he starts defeating monsters to obtain gold coins, and before he knows it, repeated gacha pulls have made him incredibly strong. After defeating the dungeon boss and stepping outside his first dungeon, he sets off alongside his gacha-machine partner and Asteria, an otherworlder he rescues along the way. Taking the name Verde Avenir, he begins a free-spirited journey to survive in another world, starting his new life as a dungeon-roaming explorer. (Source: Kadokawa, translated)
