With his kekkei genkai, Ranmaru has the ability to see and hear things from long distances. With this ability, Ranmaru was able penetrate the walls of his shack to view the outside world. Although the range of his kekkei genkai is similar to the range of the Byakugan. The kekkei genkai has the ability to counter and negate the Byakugan's ability to see chakra through objects. His abilities also allow him to perform irresistible genjutsu, which can fool even the "all-seeing" Byakugan.
