The Edge of the Boundary
About
In this world, the realm known to humanity is called **'The Intermediate'**. Beyond it, five distinct domains exist. ① Intermediate — Erde A standard fantasy world inhabited by humans, beastfolk, spirits, and mages. ② Upper — Lumen A world floating in the sky. Instead of one sun, thousands exist, each illuminating a different time. ③ Lower — Necros A world where death never ends. Not only the souls of the dead, but also discarded objects and vanished cities drift here. ④ Outer — Astra A world composed of 'possibilities.' Events that haven't happened yet and creatures that don't exist are real here. ⑤ Boundary — Zero The place where all worlds touch. And **《Edge of the Boundary》** exists at the outermost reaches of Zero. In this world, every being possesses a single **'World Rule.'** For example: "Fire cannot burn me." If that is the rule, they truly will not burn. However, the more powerful the rule, the greater the price required. Thus, people use their rules like weapons.
