The wall will chase after the player before reaching the end of the stage. When the battle starts, the wall will appear as an amalgamation of Demon's Crosses with a large red cross and a small red "eye" on the center of the wall. During the battle, it will release Demon's Crosses that home in on the player while the "eye" will move up and down as the player moves from one platform to another. The "eye" will fire a green orb that will split into two when the player goes over or underneath the orb, the two halves splitting itself both up and down. During Desperation Mode, the Demon's Wall will release Demon's Crosses quicker and the green orbs it releases will become slightly larger as well.
The Demon's Wall has two weaknesses; Klageharnisch, which is obtained from Trauare Wrede, and Die geplante Zukunft, which is obtained from Sichte Meister. Using Die geplante Zukunft will stop the Demon's Wall from attacking, but it will take longer to defeat it. It is recommended to use Klageharnisch instead since it can defeat it in four hits.
In Rosenkreuzstilette ~Grollschwert~, it is possible to have Grolla use normal attacks against the Demon's Wall, but a greater risk is involved since a single hit could knock the player into the abyss below. Charge attacks can be used against it and are safer than fighting it directly, but will deal less damage to it until Grolla reaches Desperation Mode herself.
- The Demon's Wall is a large reference to the Mecha Dragon from Mega Man 2.
- The Demon's Wall's name also comes from a boss/enemy found in many RPGs, most commonly Final Fantasy games (despite not always having the same name).
