A sensory ninja is a special type of ninja who is able to sense chakra of people. There are many sensor type ninjas in Naruto but some of them are really exceptional. So, today I have made a list of ninjas who can sense chakra from countries away.
Mū was a great Kage with great sensory skills. He was able to sense chakra from a few countries away. Also, Mū was able to distinguish the chakra of a specific individual amongst a large population.
