the Kâma of Boruto is a diamond seal engraved on his right palm by Momoshiki Ōtsutsuki just before he died.
It contains the genetic data of the’Ōtsutsuki and gradually rewrites the biology of its host to enable its reincarnation. The more Boruto's chakra weakens, the more Momoshiki can take control.

Kâma, definition and importance
the Kâma is a backup seal which preserves the biological data of a member of the clan Ôtsutsuki. It works like a compressed genetic code : Once imprinted on a human host, this code gradually rewrites its DNA.
It works in three steps:
- The seal is engraved on the body of a compatible individual, known as container.
- Data from the Kâma are gradually rewriting the genetics of the receptacle.
- Once the rewrite is complete, the carrier becomes a true Ôtsutsuki.
So it's not just a DNA file. It's a process of reincarnation a complete process that transforms the host into an exact copy of the’Ôtsutsuki of origin. When the latter dies, its essence migrates to the vessel and eventually supplants it.
Moving forward, two definitions are useful:
- Boruto Kâma : the seal that Boruto receives from Momoshiki Ôtsutsuki after their fight.
- Clan Ôtsutsuki : a race of aliens that travels the universe to seize control of the divine fruits and sources of chakra planets.
Boruto Kâma, Momoshiki's seal

History of Boruto's Kâma
Momoshiki arrives on Earth with Kinshiki with the aim of seizing the Naruto's chakra, which holds the power of the Nine-Tailed Demon Fox. With the help of Sasuke and his father, Boruto manages to defeat him.
It was right after that fight that everything changed. Before he died, Momoshiki Ōtsutsuki grabs Boruto's hand and deliberately establishes his Kâma, while promising him that he'll end up losing everything.
- The seal takes the form of a black diamond on the right palm from Boruto.
- It acts as a backup of Momoshiki's genetic data, a sort of survival ritual in disguise.
- Ultimately, this process of reincarnation should enable Momoshiki Regains His Form by making Boruto his vessel.
In short, Boruto unwittingly becomes the host for a member of the clan Ôtsutsuki. Reincarnation does not happen immediately: it progresses with each Activation of Kâma. The more Boruto activates the seal in battle, the further the rewriting process progresses.

Boruto Uzumaki, Naruto's son

To fully understand the significance of the Kâma, you need to know the person wearing it. Boruto Uzumaki is the main character in Boruto: Naruto Next Generations. He is the son of Naruto, the Seventh Hokage of Konohaand Hinata Hyūga.
A young ninja on Team 7 alongside Sarada and mitsuki (the artificial son of’Orochimaru), Boruto has already mastered ninjutsu, taijutsu, kenjutsu, and fûinjutsu. He also possesses a unique dôjutsu, the Jôgan, an eye capable of perceiving the chakra and the gaps between dimensions.
It is precisely this extraordinary profile that makes him a prime target for the clan Ôtsutsuki. After his victory over Momoshiki, Boruto finds himself marked by the Kâma, inextricably linked to the clan's fate.

Link between Boruto and Kawaki
Kawaki also has a Kâma, that of’Isshiki Ôtsutsuki. This Kāma was passed down to him by Jigen, the head of the organization Kara, which itself served as a receptacle for Isshiki.
The mechanism is the same as in Boruto: Isshiki seeks to be reincarnated as Kawaki by rewriting its genetic code through the Kâma. It is this shared seal that creates a resonance between the two boys and binds their fates together.
They meet just as Kawaki is being chased by members of the organization Kara. Naruto then takes him back to Konoha to keep it safe. Check out The 10 Hokage in Naruto to better understand Naruto's role in this story.
Boruto at first appears suspicious and hostile toward Kawaki. As time goes on, he grows closer to him as he learns about his tragic past. Above all, the two share the same desire: free yourself from Kâma.
Their relationship is changing in several ways:
- They learn to Mastering Kâma Together, by practicing with Naruto and Sasuke.
- They stand side by side against the members of Kara, who are trying to recover Kawaki to return it to Jigen.
- A sincere friendship A bond develops between them, to the point that they consider each other brothers.
- They vow to protect Konoha at any cost.
However, this link remains a a constant source of danger. He puts them both in danger from the clan Ôtsutsuki, who wants to use them as vessels for reincarnation.
the flash-forward from the first episode The anime makes this abundantly clear: Boruto and Kawaki one day face off on the ruins of Konoha, with some Advanced Kâmas and powers that are ten times greater.
In the manga, this advanced form manifests as the near-total extraction of Momoshiki's data—up to 100 %—a sign that the reincarnation is nearly complete.
The Kâma is not just a seal: it is the driving force behind the entire plot of Boruto : Naruto Next Generations. It's up to you to see if Boruto will manage to break free from Momoshiki before reincarnation is complete.
