Based on the idea cemented over time in countless people that "monsters lurk within a labyrinth," comes the idea, "places where monsters lurk must be labyrinths". By reversing causality and forming a Philosophical Armament, a dungeon, Daedalus' Labyrinth, can be created.
They are able to construct and deconstruct conceptual boundaries A, B, and C (the roof, the floor, and the walls) at will, forming an inescapable labyrinth spanning over 380,000 kilometers that swallows their prey whole.
However, its use greatly exhausts the trio, and they are unable to maintain it for longer than ten minutes, allowing their prey to escape and exposing a simple yet fatal flaw. In an attempt to compensate for this flaw, Noble Red (particularly Elsa) began to use the labyrinth as a confined space to compress energy into as a form of attack. This technique is known as "Daedalus End".
At full power, the energy is explosive enough to destroy even the conceptual boundaries of the labyrinth. This allows the trio to far surpass their normal combat potential for a single decisive blow. In other words, Noble Red has no other attack more powerful than Daedalus End used at full power.
- The length of the labyrinth, 380,000km, is the length of distance between the Earth and its moon.
