Akahoshi discovered that he had a kekkei genkai a while back, this Kekkei Genkai is called by Akahoshi, the Memagan. Memagan is a dōjutsu kekkei genkai similar to the Byakugan. It includes penetrating vision, to counter and negate other dōjutsu, and a unique chakra particle extension. The user has the ability to use their vision abilities to penetrate walls of and perform genjutsu that can fool even the Byakugan.

 

   This ability does have a similar range of the Byakugan as well.The user's vision also lets them locate and track others by sensing chakra, picking up chakra from long distances, and noticing changes in an individual's chakra. It is also able to sense how many individuals are present. The user's vision has heightened perception and analytical powers not unlike the Sharingan, meaning they can comprehend any details they see to predict the opponent's next move.

 

  It also allows the user to see one's life force, allowing the user to determine that a ninja was still alive. The user can also transfer part of their life force to another, which would in turn completely heal someone who was almost dead. When activated, the user's eyes momentarily glow red.
