In this chapter, we learn that the main pipe of the water treatment plant splits into several smaller pipes, each with its own entrance. Each of these pipes is connected to a cube, which can be used for any number of purposes, including a gymnasium, a public park, a swimming pool, or even a public toilet. In other words, any room can be transformed into a battlefield. Agito's plan is to use the mask of a croissant to gain at least one victory for the team, but he needs to figure out a way to switch the places in order to do so.
