Shimura Mashiro, Danzo's only son.
In everyone's eyes, he has weak chakra and poor physical skills, and is a waste destined to fail to graduate. At the critical moment of the graduation exam, he accidentally obtained the "Swordsman Template". In just twenty seconds, the blade was fast enough to reverse the defeat.
But after the twenty seconds were over, what awaited him was not applause, but fatigue, tinnitus, pain, and a long cooling period before he could use it again.
In order to survive and not become a pawn in the hands of his father, Mashiro was forced into Kaiban by Danzo, becoming the fourth person besides Li, Neji and Tenten.
One is responsible for breakthroughs, one has insight into the overall situation, and the other controls the mechanism, and he can only find victory opportunities within a limited burst time.
Mission to the Land of Waves, Chunin Examination, official competition arena, collapse of Konoha...
He can't win every battle, and he can't save everyone, but he has to prove in every choice: Danzo's son doesn't have to be the root of the sword, and a waste can use his own way to reach the end with his companions.
Beautiful and innovative
