Boruto Jougan Chakra Mode
Sage mode is known to be taught in two places.
Boruto jougan chakra mode. At mount myōboku by the toads and at ryūchi cave. It is known as the pure eye. In the naruto franchise chakra is the power used to form the attacks the ninjas use.
It s just a wild baseless theory i have for boruto s supposed cursed power. Sage mode allows users to tap into the natural force of the world opening up new techniques to them and allowing them to power up existing ones with the new senjutsu chakra. Naruto next generations saw naruto make a dark deal with nine tails spoilers.
Boruto s eye knows as jougan also knows as a pure eye which is a form of tenseigan. There is no evidence to back this up. It can perceive the flow of chakra enabling boruto to see the visible changes in one s chakra and likewise track a target through their chakra.
Sage mode is an empowered state that can be entered by blending natural energy with one s chakra creating senjutsu chakra. Although it has not been explicitly mentioned in the anime but the translation of a manga panel indicates so. The term refers to pure eye and its structure is quite similar to naruto s eyes when he senses evil chakra or when he is releasing his darkest side.
Its called the pure eye. The jougan combined with his seal will allow boruto to siphon off souls from the pure world transmute them and use the resultant chakra. Before gaining control of this dōjutsu it would independently activate in the presence of dangerous hidden targets.
Boruto activated jougan during fight with mitsuki vs nue on a particular scene nue s chakra triggered boruto which results in revealing the new dojutsu jougan. Using his eye boruto has been able to track certain chakra signature. They will sacrifice themselves to unleash a level of power they ve never tapped into.
