Mito and Naruto are sensors due to the 9-tails
Karin specializes in sensing.
I have discussed this topic a lot. Many people seeems to attribute everything to Kyuubi. However, this is not true. Naruto's only problem is that he had no guidance to focus on his own abilities, and he is even almost ignorant of his own identity. Otherwise, Naruto could have discovered that he is a sensor all by himself. Sasuke father knew he is Uchiha, so he knew that somewhere Sasuke has fire inside him. This is why he took him for fire training. Naruto lacked all this guidance, and all the people who knows him only focused on Kyuubi. Therefore, they attribute everything to Kyuubi. Now let start the show.
The chakra Naruto took from Kyuubi has no mind, no eyes, no ears. So how could Naruto's sensing ability be Kyuubi's? The only thing happening here is that Naruto is obtaining a boost of his senses due to the overwhelming chakra of Kyuubi in the same way it got a boost in SM. This means that the quantity of the chakra and is what activate the sensing power. Therefore, if Naruto had the proper training to produce his own massive chakra and focus it on a particular sense, he would become a sensor naturally. Don't also forget Minato was a sensor similar to Tobirama.
What I am saying is the same as regeneration. If Naruto could focus his own chakra on his wound, he would regenerate just like Tsunade. His only problem is that no one was there to teach him. Thanks to his parent, he inherit a source of chakra that play the same role that his own skill would have played if his parent were around. To put it short, regeneration, sensing, and powerful chakra are Naruto's own feats. Naruto body can regenerate over and over because he is Uzumaki. He can sense because he is Uzumaki. His body can take Kyuubi's chakra because his own chakra is stronger than Kyuubi's, strong enough to suppress Kyuubi's chakra.
Actually, if you compare Killer Bee's V2 and Naruto's V2 Kyuubi, they are different. Naruto's V2 causes a lot of shockwave that many attribute to Kyuubi as well. Actually, if you think about it, you will notice that in V2, Naruto's own chakra is mixed with Kyuubi's. Thus, Naruto's wind element also is in the chakra causing a lot of turbulence. When Naruto took Kyuubi's chakra in KM and used it alone, there was no wind and no swirling. However, when Naruto mixed it with his own chakra and did the conversion, the same disturbance seen in V2 came out so strong that even non-sensory ninja could feel it in the air in Konoha.
The mistake people do with Naruto's power was the same that the could ninja did when he felt Naruto's chakra. At first, he was in respect for the overwhelming power thinking it was Kyuubi's. Then, he notice that it was Naruto's because he is himself a sensor. If this guy wasn't there, everyone would say that Naruto was using Kyuubi's power.
Conclusion of the rant:
Uzumaki in the series: Mito, Kushina, Nagato, Karin, and Naruto.
- We don't know about Kushina
- Nagato, Karin, Naruto, and Karin are great sensors
- Kushina, Naruto and Mito were Jinchuriki.
If you do the math, there are more than 50% for Naruto and Mito to be naturally sensors.
