|This is the article on the mark. For other uses, see Kama (disambiguation).|
Kāma is a seal that takes the shape of a black diamond on the user's body. Although unfamiliar to the population at large, Kara has gathered intel on it and similar seals. Koji Kashin implies that Kāma can be obtained by killing a member of the Ōtsutsuki Clan.
- Jigen bears the mark on his chin. How he acquired it is unknown. When activated it spreads across his face and body in nearly symmetrical sunburst patterns.
- Boruto Uzumaki received the mark on his right palm after dealing a fatal blow on Momoshiki Ōtsutsuki. When activated it spreads across the right side of his body forming angular and curving geometric patterns, extending up to his right eye, and then glows blue.
- Kawaki received the mark on his left palm through scientific experiments conducted by Jigen. When activated it spreads across the left side of his body forming a pattern that almost perfectly mirrors Boruto's, extending up to his left eye, and then glows red.
When activated, Kāma significantly enhances the user's physical abilities and jutsu's power. It could also absorb enemy's attacks like ninjutsu and large-scale explosions. Boruto's and Kawaki's Kāma exhibit resonance (共鳴, kyōmei) when in close proximity. When their Kāma resonate, it apparently enables them to release anything that either of them had previously absorbed. This resonance also seems to be independent from the origins of the involving Kāma, as Kawaki got his from Jigen, while Boruto got his from defeating Momoshiki.
Kawaki could activate it at will by the time he first met Boruto and three years later, Boruto was able to activate the seal at will as well, while Jigen was fully capable of activating it any time he desires. Boruto's resonated Kāma could also be forcefully activated when Kawaki activates his own nearby. Using Kāma in battle causes Kawaki's body to overheat, leaving him unconscious. Boruto also collapsed after using it for the first time.
Through the aid of science, Jigen can use his Kāma to transfer Kāma to other individuals, albeit with a low rate of success, as of fifteen known test subjects, thirteen are confirmed to have died, with Kawaki the only known successful recipient. Jigen has also shown the ability to absorb chakra from creatures that are similar to tailed beasts.
According to Jigen, when a person receives a Kāma, they become a "vessel" (器, Utsuwa).
- Although the kanji itself would normally be translated as "linchpin" (楔, Kusabi), the furigana indicate the reading "kāma" (カーマ). "Kāma" means "wish", "desire", or "longing" in Hindu literature. In Japanese it is also an uncommon way to write "karma".
