Naruto, Blade of the Ninja World

Traveled through Naruto and became a Uchiha affiliate, named Rin. Because of the "rational" thinking of social animals in previous lives, they would first calculate the "risk-benefit ratio" before each action. When his memory awakened, the first question he calculated was: How to survive the night of genocide? The answer is cold and desperate, fleeing alone is a dead end. Saving Uchiha is the best solution. While his fellow clan members were still struggling with the "glory of the clan emblem", he had regarded the entire clan as an "asset" that must be saved. When the protagonist of the plot is still chasing the bond, his system is quietly activated - "Hokage VS Death", the form switches, and the weapon appears. From then on, Uchiha's "cold blade" was quietly unsheathed. He used Naruto and Death as his training ground, fighting against protagonists and villains from all walks of life. Lay out in the shadows, treating Shisui, Itachi, and Danzo as variables on the chessboard. On the night of the genocide, when Itachi and Obito appeared with sharp blades in their hands, what they saw was a figure wearing a Death Overlord costume and carrying Zangetsu on his shoulders. Uchiha Rin's eyes were cold and his Zanpakutō pointed straight ahead: "I have calculated that saving Uchiha has the highest rate of return. Now, let's talk about the conditions again."
