Kouda's Unknown Dōjutsu

Kouda possesses a unique, unlabeled dōjutsu that he calls the Manjidani (万地谷, Manjidani), named after his supposed birthplace. The Manjidani functions similarly to dōjutsu such as the Sharingan, Byakugan, Rinnegan, and Ranmaru's Kekkei Genkai, with many refeering to it as the Ultimate Dōjutsu. It allows Kouda penetrating vision, the ability to disrupt eye-based kekkei genkai and the ability to grant the user incredibly clear perception, allowing them to sense and disrupt a genjutsu and recognize a person's chakra by color, which they can easily see. It allows them to pick up on small details; Kouda was able to identify two identical twins by a tiny superficial scar to one's back, while the other one did not have one and being able to read lips and track subtle movements. Kouda's dōjutsu has heightened perception and analytical powers unlike any known dōjutsu to date, meaning Kouda can comprehend any details he sees to predict the opponent's next move. Kouda can easily track fast-moving objects; in fact, they appear to be moving at bullet speed compared to the user. Using his dojutsu, he is able to even fool the Rinnegan with his genjutsu. Kouda is capable of locating and tracking othrs by sensing chakra, picking up chakra from long distances, and noticing changes in an individual's chakra. It is also able to sense how many individuals are present. At one point, it has even been shown that Kouda has a heightened sense of vision, being able to block a shuriken that was traveling behind him; this may or may not have been due to his dōjutsu, and rather by his heightened sense of hearing.

Kouda's dojutsu contains a secondary ability which induces hypnosis, amplifying negative thoughts, mentally breaking down the opponent. It reverses the homicidal intent of anyone who meets the stare of Kouda's eyes while his dojutsu is activated. If someone expresses hostility toward him, Kouda is easily able to will the opponent into killing themselves.

Kouda's dōjutsu makes it possible to neutralize the techniques of any ninja that meets his stare directly. It seems to operate by inducing significant internal pain upon the recepient, causing the victim or victims to lose concentration, halting whatever technique hey were utilizing at the moment.
