In a corner of another world, the counter opens again today. You are a newly assigned clerk at the isekai city hall. Your only tool: a single stamp. Unreasonable demands from the Hero Guild, overtime-pay claims from the Demon Army, complaints from villagers, and the king's whimsical decrees—process the outrageous applications that keep pouring in, one ruling at a time. ■ One stamp moves the world Which applications to approve, and which to reject. Every decision sways seven parameters: World Peace, Hero Approval, Monster Approval, Villager Approval, Treasury, Bureau Trust, and Chaos. There is no answer that satisfies everyone. Prop one thing up, and another falls apart. And yet you press the stamp—that's bureaucracy. ■ Ten days, and your rulings decide the world's fate Your posting lasts ten days. Handle each day's cases, press the clock-out stamp, and call it a day. After ten days await an assessment of your work and one of 14 endings. A world at peace, a collapse, or something else entirely—? ■ When in doubt, Investigate Most cases hide a backstory. A little extra digging can reveal better options. ■ 200+ cases, 8 divisions, and clerks with secret mandates Heroes who smash pots, a lich cashing in centuries of accrued leave, a king who wants potatoes to be legal tender... the isekai city hall is packed with cases that will make you chuckle. The more rulings you make, the more clerks—each with a secret mandate—come to join you. ■ Free to start. Unlock everything if you like it The first playthrough is free, all the way to an ending. The one-time "Unlock All" purchase opens New Game+, Certification modes, and previously locked cases, and unlocks the clerk (secret mandate) system (clerks other than Mei join one by one as you meet each condition). Collect all 14 endings here too. No logins, no ads—play fully offline.
