Genjutsu: Shut Down

By simply glowing their crimson eyes, courtesy of their kekkei genkai, the user casts the illusion to anyone who catches even a glimpse of sight of the glow. Within an instant, the target's eyesight shuts down completely, and since this kekkei genkai incorporates eye technique disruption as one of its primary abilities, all dojutsu are nullified and completely disabled. The technique can only be released by the user or by killing them.
