Operation Magic

Operation Magic (操作魔法 Sōsa Mahō) is a Caster Magic, created by Roy Netero in order to cure his father from a fatal illness. It is so powerful and dangerous that Roy refuses to teach it to anyone else beside himself.

It allows the user to create a spherical space or "room", in which the user has complete control over the placement and orientation of the objects inside, making the user a Free Modification Human (改造自在人間 Kaizō Jizai Ningen). It is named Operation magic, as the space the user creates is compared to an operating room and the user to a surgeon.
