Cover Details
Volume 21's cover shows the battle taking place in chapter 88. From debris flying, Noya has broken through the wall into the building where Yu and Mika are. While Yu appears to be considering something, Mika has his sword drawn. Noya wields two weapons, the foremost sword in his left hand is black and red, similar to Guren's Cursed Gear, the second blade appears all red. His hair color is depicted as all red, and Noya's tattered clothing around his waist is dark in coloration.

Behind Noya stands Guren in the opening of the break in the wall. Having red eyes, Guren's large demon horns are somewhat visible. Retaining the power sapped from his squad, Guren appears to be unsheathing his sword. At this point, Mahiru would have been returned to Guren's weapon.
