Naruto: So I Tried to Take the Nine-Tails. Now Everyone's Crying. What Did I Do?

[Naruto Fanfiction + Misunderstood Flow + Dark Style + High IQ] Uchiha Shichiya has been in the Naruto world for fifteen years, always a plain and unremarkable "failure." Until one day, he awakens the Mangekyō Sharingan and unlocks the heaven-defying ability to "absorb chakra"! His goal is crystal clear: to get his hands on the vast chakra within the Nine-Tails jinchuriki! To get close to his target, he disguises himself as a gentle and considerate "Will of Fire" successor. He provides Kushina with psychological counseling, helps Tsunade formulate medicine, and even showers the Uchiha clan members with care and attention. "Who cares if I sacrifice a little charm? As long as I gain power." But the development of events seems a bit off… Tsunade: "Shichiya is a more perfect disciple than Orochimaru. He even knows medical ninjutsu better than I do!" Third Hokage: "He is Konoha's pride. The Will of Fire burns to its utmost within him!" Uchiha Mikoto: "Shichiya-kun is so gentle. He must be working so hard for the clan's sake…" Looking at these Konoha higher-ups, all fooled by his "acting," Shichiya falls into deep thought. "I only wanted to drain Kurama dry. Why is everyone treating me like a savior?" "And Mikoto, why are you crying? I just wanted to use your house as cover!" This is the story of "how to turn all of Konoha's top combat power into his own nourishment without exposing himself (even though he's about to crack)"!
