Seiichi works a boring, badly paid job at a regular convenience store. One day, he’s suddenly reincarnated into a new world full of endless possibilities! …Well, not really. Thinking he was signing up with a heroic guild, he accidentally ends up working for Grandmaster Lumir’s chain of stores. From one convenience store to another! Can he handle annoying customers, weirdos, and all the bizarre dangers of this magical world? Of course he can — if he survived a regular convenience store, he can survive this… probably.
