Kāma (The Seal)
After defeating Momoshiki, Boruto received a seal on his right hand in the shape of a diamond. When activated, it can change and expand to cover more of Boruto’s body to various degrees. Its activation takes a toll on Boruto’s chakra, and with it, Boruto can absorb other techniques, like fūinjutsu and nature transformation.
Jōgan (His Right Eye)
From the unknown aid of Toneri Ōtsutsuki, at the age of eight, Boruto subconsciously awakened the Jōgan in his right eye. While originally only able to instinctively activate it in times of threats, at age sixteen, he became able to activate it at will. It grants him the ability to detect things such as chakra which is generally unseen by a normal eye. This dōjutsu can perceive the flow of chakra, enabling Boruto to see the visible changes in one’s chakra and likewise track a target through its chakra. It can also determine the key point of the chakra pathway system, and see through invisible barriers that connect between dimensions. Due to possessing the blood of a Byakugan wielder, he was able to communicate with Momoshiki’s deceased spirit.
