The Byakugan (White Eye) is one of the most powerful Dojutsu (co-jutsu) in Naruto history. This is the kekkei genkai of the Hyuga clan. The Byakugan’s telltale sign is the characteristic white eyes and no pupils, when used, the user will have many veins on both sides of the temples.
The eyes of the White Eye carry amazing powers that everyone covets such as: extremely long, extremely wide vision (except for a “blind” spot near the first vertebrae), seeing through everything (including objects). solid state, fog or smoke), and also chakra flow. The Byakugan also has the ability to distinguish between clones and legs and track movements at high speed.
Therefore, nothing escapes the eyes of the Byakugan user, even the invisible ones. However, if you pay attention you will see that there are not many stealth techniques used by ninjas in Naruto. The reason may be that this type of ninjutsu isn’t possible against the possessor of the Byakugan and Sharingan.
Specifically, in the event that the enemy uses a camouflage technique that makes the body invisible, making it difficult for a well-trained shinobi to detect, if only based on sound, The smell, the difference in air circulation… However, the user of the Byakugan and Sharingan jutsu is easily recognized, thanks to the ability to see chakra.
Even if an enemy uses a technique that makes chakra invisible, a Hyuuga or Uchiha clan with a Byakugan and Sharingan can still detect the chakra being used and “see” the enemy. Uchiha Obito was able to do this immediately after awakening his Sharingan.
The only ninja who can make himself completely undetected is the Tsuchikage Second Mu of the Stone Village. He is nicknamed the “Shadow Man” due to his invisibility, and at the same time concealing his chakra from his senses.
