Dummy Check (視覚阻害 (ダミーチェック) Shikaku Sogai (Damī Chekku)?, lit. "Visual Inhibition") is the esper ability that allows the user to lessen their presence from other people. The higher levels mean that a user can seemingly become invisible to a person even if people are looking straight at them. It is unknown whether or not this also affects animals. Furthermore, users cannot hide their presence from secondary sources, such as cameras or mirrors. This makes the ability more akin to Mind Hound, rather than actual invisibility.
