Eyeball Magic 「眼魔法 Manako Mahō」 is a magic attribute that allows the user to manifest eyeballs.
This magic attribute allows the user to manifest additional eyeballs that are free-floating, can turn and move in midair, and share vision with the user. In order to use it to its full potential, specific spells are required, which are stored within grimoires.
These eyes could be spread out over a large area, allowing the user to see from multiple angles and over great distances. The eyesight could also be enhanced in order to perceive a target's magic, stamina, and muscle movements.
