Ozaki

Mauthenia is a city that does not grow outward — it grows inward. With the outside world sealed behind a Limit no one dares to cross, humanity stacks district upon district, carving endless depths while the Order of Vigil patrols the borders of the unknown. For most people, that is enough. The city is safe. The world ends there. Ozaki Kurose never believed it. Heir to a lineage marked by the Order, he enlists in search of answers the city would rather forget. Beyond the Limit lie echoes of other civilizations, abandoned territories… and the lingering shadow of an ancient cycle said to awaken once every millennium. As Mauthenia sinks deeper into itself and whispers of that forgotten era resurface, Ozaki is drawn into a truth that may redefine what it means to be safe — and the price of crossing into the unknown.
