Genjutsu: The Sound of Drums

Genjutsu: The Sound of Drums is another of Kisui's Rinnegan techniques. By activating the genjutsu via eye contact, the victim's mind begins repeating a simple pattern. Four drum beats in a second by second loop, constantly repeating in their mind. The sound of it tears away at the victim's mind, leaving them mentally weak until their mental state deteriorates completely, leaving them completely insane.
