I try to keep everyone in character and follow the original style. This is not a power fantasy, and there are no elements from any series other than Naruto.
Spoilers and warnings: The protagonist is the original Izuna on his third life. After dying in the original story, he lost his memories, went to the modern world, and then returned to the original story with his modern memories. So he is obsessed with his older brother, somewhat arrogant and conceited, and hates Senju ninja. He is not an overpowered protagonist or a strategist who calculates every step. He may even suffer for his arrogance, and he has his own pride and convictions. He will not act out of character.
If that bothers you, please don't read. Decide for yourself whether this is for you.
