The Flashing Ape from Naruto

A college student accidentally transmigrates to the world of Naruto, but not to the era he knows. The Third Great Ninja War has yet to begin, and Danzo and old man Sarutobi are scheming against each other. The protagonist has nothing to say about that. As long as nobody messes with him, he's fine. But not paying him a salary? That's a serious problem! All he wants is to stay alive and keep his head down. He'd planned to trick Guy into teaching him the Eight Gates, then focus on mastering taijutsu. That would be enough to keep him safe. Little did he know... By a twist of fate, he stumbled upon the kekkei genkai his clan had wanted for generations: Light Release. Well, isn't that enough to go to his head? “Yasakani no Magatama!” Uchiha Itachi: ... “Ama no Murakumo!” Orochimaru: ... Whenever he meets someone, he greets them with, “Oh my, how frightening!” “Young people these days really are something!” “Speed is weight... By the way... have you ever been kicked at the speed of light?” This is the story of a transmigrator who gradually grows more brazen and shameless.
