Naruto: Thousand Hands of Rebellious Blades

[Protagonist has no system + I don't know the plot + Ninjutsu style] The so-called ninja is just a person who endures pain and lives! There are no born heroes here, only mortals who are forced to be strong! Since you are alive, you must do something for those companions who have fought together. Because under that Konoha tree dyed red with blood, there is always a belief engraved on it: Ninjas are existences that endure pain to protect important people.
