Synopsis
Ten years after mysterious beings called Danpons arrived and built dungeons into everyday Japanese life, high schooler Taira Ichino visits the dungeon at Osaka's Umeda Station and leaves with almost nothing — minimal experience points and an unopenable mystery can called a D-Can. When it finally cracks open at home, he finds candy that teaches skills. He eats it. He goes back to the dungeon. He has very high initial luck and a canned gacha system nobody else seems to have, and he intends to find out how far that combination can take him.
