Naruto being a ninja-focused story, Chakara is something very special. If a ninja uses up all his chakara, normal ninjutsu illusions cannot be used. In the ninja world, there are five ninjas, and they never have to worry about running out of chakra!
Dried persimmon Kisame
As a tailless beast, Kisame has a huge amount of chakra and can use all kinds of ninjutsu and genjutsu without any hesitation. The source of his chakra should be his Samehada sword, which is a living animal-type ninja tool. Kisame Kisaki is good at using water escape, and his range is very large, so he is not afraid of running out of chakara.
Metkai
Akai is a bit special. He doesn't use ninjutsu or illusions very much, so he doesn't have to worry about Chakara. His disciple Locke Li also had the same situation. I don't know if it was a blessing in disguise. Akai is best at physical attacks and eight-door armor. Chakra is really not a problem. Occasionally, the psychic old turtle will probably use it a little.
Senju Pillar
The first Hokage, Senju Hashirama, has a fairy body, so he doesn't have to worry too much about chakra, and the wood release ninjutsu he uses also has a huge range.
Uzumaki Naruto
The son of the Fourth Hokage, he also has the body of an immortal, and has the halo of the protagonist and the protection of the nine-tailed beast. Naruto has never worried about his chakra. He probably can't understand Kakashi-sensei's pain. After all, you can't use up one chakra no matter how you use it, and you still have to count the uses of each chakra.
Otsutsuki Kaguya
The mother of the Sage of Six Paths and the ancestor of the ninja, Kaguya should have transcended the limitations of Chakara. The ninjutsu or genjutsu used are all at the level of super gods, and it has long been no longer necessary to care about how much chakara is consumed. There is probably no one in the entire ninja world who can achieve this level. After all, he has the dignity of the final BOSS!
