Naruto: Taijutsu Gone Wild

The previous mistakes, Kai's title, and ninja level are all wrong. Regardless, the writing in the back is getting worse and worse. Starting after the third war, when the protagonist followed Orochimaru to do research, something started to go wrong. The protagonist seemed to have suddenly changed. Was it written by someone else? The protagonist suddenly turns dark. He says in front of everyone that he will kill anyone who dares to interrupt his battle with Kyuubi. After that, he runs to the center of Konoha if he can't beat him. As mentioned before, the protagonist gives the cloning technology to Orochimaru to increase the strength of the villain to avoid being bored in the future. So the protagonist has completely turned dark from a relatively good front, and has lost track of what is going on later. If the protagonist hadn't been the protagonist of this book, he would have been beaten to death by the third generation. Do you really think that the third generation is a kind person?

Where did the blue beast come from during the Third War? Gai and Kakashi are about the same size, right? Kakashi is the disciple of Namikaze Minato, and Namikaze Minato became the Fourth Hokage after he rose up during the Third War.

You said that there is a person in the world of Naruto who has a physique that reaches the level of Kaido or even surpasses him. He is 1.9 Meters tall, has an armament color that reaches the level of Garp or even surpasses the Overlord color and has red hair.

Did all Kai's efforts go to waste?
