The Second Tsuchikage was distinguished by absolute composure and never lost his self-control in any situation. He was invariably polite, addressing even his mortal enemy Gengetsu with formal respect, but this did not reflect his true feelings. Muu's main trait was ruthless pragmatism: he placed the prosperity of Iwagakure above any alliances and moral constraints. It was he who taught Onoki to profit from the post-war chaos, which ultimately created the Hidden Stone's reputation as a treacherous village. In battle, Muu preferred covert killings, using his ability to become completely invisible and intangible, but when necessary he acted openly and methodically. He tolerated weakness neither in himself nor in others and demanded the same severity from his students. His personal feud with the Second Mizukage remained the only antipathy he hardly concealed, yet even there he maintained cold courtesy. Defeat by Madara Uchiha did not break him, only strengthening his determination to strengthen his own village for a future rematch. Muu did not hesitate to destroy enemies with the Dust element, considering strength the highest argument of a Kage. Despite his secrecy, he personally led key operations and never hid behind the backs of his subordinates. There was no ostentatious pathos in him — only calculation and loyalty to Iwagakure. He conducted any negotiations from a position of strength, leaving his rivals no room to maneuver. Emotions never influenced his decisions, and his every word and action served a single goal — the elevation of his native village.
