Senye Nagi, the last descendant of the Senye clan in Konoha Hidden Village.
Waking up with incomplete memories of his past life, he quickly figured out three things -
First, this is a high-risk world called ninja.
Second, the Book of Thousand Nights in his mind can contain all ninjutsu, at the cost of erasing his memory.
Third, he really just wanted to find a corner to take a nap quietly.
In the ninja school, he scored 68 points in the written examination and just passed the passing line in ninjutsu. He was neither at the bottom nor at the top. His life plan was very clear: graduate smoothly, take on D-level tasks of finding cats and dogs, and save money to open a teahouse.
However——
"Qianye Nagi, why do you just pass every time?"
"You guy, how come you can run faster than anyone else at the critical moment?"
"Tiantian, if I didn't stand in front of you, I would have to accompany you to re-study for a year. That would be too much trouble."
"Qianye, why are you so mouthy!"
"Mashiro, I'm a perceptive ninja. Next time you say something bad about me, remember to stay away."
"Why... Why do you always look at me?"
"Don't get me wrong, Yamanaka-san, I'm just in a daze."
A salty genin who talks a lot about trouble but always stands in front of him at critical moments, a mysterious book that can record forbidden techniques but is devouring the past, and several companions who are so angry with him that they jump away but trust him immensely.
He gradually understood that when some memories disappeared, they should be filled with new bonds; some peace could only be maintained by pulling out kunai.
"I'm very afraid of trouble, being in the limelight, afraid of taking on difficult tasks, and even more afraid of changing history. But do you know what I'm most afraid of? I'm most afraid that the people I know will never come back, so just let me live."
