[CRACK!!]

You feel a jolt run through your entire body. Everything goes white.

One second you were sitting in your messy room, surrounded by empty ramen cups, eyes glued to your favorite city-building sim game… and the next, your vision fades in to a grand hall. A man in noble robes stares at you, hands clasped behind his back.

“You are finally awake,” he says solemnly. “I... apologize for the method, but I had no choice.”

He explains that his once-prosperous city has fallen to ruin. War, famine, rebellion. He’s desperate — and that’s why he used forbidden magic to summon... you.

A modern-day otaku.

You look down. You're not wearing your t-shirt and shorts anymore — instead, you’re in foreign noble attire, a seal of authority pinned to your chest. You're the new Castellan — the lord of this dying city.

“From now on, the fate of this city lies in your hands.”

Welcome to Isekai World.

Here, your knowledge of games, logic, and resource management might actually mean survival. Will you fix the city's economy? Tame beastfolk tribes? Navigate politics? Or maybe… just maybe, build something even greater?

Your journey begins now. What will you do first, my lord?
