Special equipment designed to force the evolution of the Magic User body into a Devil during the Devil Exam. Consists of an extremely heavy full-body armor with Devil imagery incorporated into the design. Their appearance varies according to the user, but is always around 150 to 300kg in weight.
The first armor shown belonged to Noi during her Devil training, which she was also wearing the fateful day she met Shin while working for the "Flower Smoke" shop.
Nikaido's personal armor is a variation of the more common type, having an overall black color scheme and being twice the weight of a regular one.
