The Avatar Of Manipulation

In a shinobi-dominated verse, there lived a young kid, Kuragari Watanabe, born with six rare abilities passed down from the most formidable ninja of his time. He was ignorant about the sublime abilities he possessed until his best friend, Zaku Atta, disguised as a spy, sought his life for the purpose of his nation and their goals. He was sent on a mission to bring the heir of this unique blood trait to reincarnate his sensei and fuse the kid's blood with his sensei, Kagame, to access the magnificent abilities in the blood, and take dominion over the six great shinobi nations. Furthermore, this evil plot was uncovered and terminated by the kid's brother, Ichiro. He went toe to toe with the spy and managed to brutally wound him at the cost of his life. The intruder barely managed to escape back to his land with all the injuries he got from the intense battle with Ichiro. Kuragari was then taken up by an ally of the land of ice, referred to as the land of clouds, and trained under one of the most renowned sensei of all time. He taught Kuragari how to utilize his prowess. Kuragari made up his mind to embark on a quest to avenge his brother's death. However, that wasn't the end of the misery. Zaku revived his sensei, Lord Kagame, and then went into rehabilitation. Lord Kagame was unhappy because Zaku failed to bring the heir, Kuragari, to him. It was up to Lord Kagame to decide the fate of his nation. Can the six shinobi nations hold out against the one? Can Kuragari avenge his brother's death? The answer is ambiguous until you read the book.
