The main character gains a “Character Roleplay System” — the more accurately he imitates the character, the stronger his abilities become. Uchiha Itachi: “He doesn’t have any chakra flowing through him, so how is my best bro using all these unknown jutsu?” Minato Namikaze: “This guy’s teleportation is even faster than my Flying Thunder God!” Kisame: “What the—? I know every single hand sign there is, so why have I never seen his gestures before? This is so frustrating!”
