There is no blood limit, and there are no cheats. The twelve-year-old Gekko Shin is just cannon fodder from the lowest level in Konoha.
In the place where corpses were piled up on the battlefield, he unexpectedly saw the irrefutable evidence that the people above had used it as bait and sold it. These things completely overturned the so-called "will of fire". It was just a lie that made people die.
In the heavy rain, he lived to cut open the rotten flesh on his thighs. He sewed the evidence scroll into his body using rough methods, and then crawled back to Konoha Village with blood and mud.
Since the obedient person has only one way to die in the end, he decides to become a mad dog, a mad dog that wants to bite people when it sees it.
He was holding a broken knife with a curled blade, and was involved in the games from the top. He wanted to completely split this seemingly hypocritical ninja world from the middle. He would bite the throat of anyone who blocked his way of survival.
