Background / History
Mu served as a leading guard of the Land of Earth's delegation during Hashirama's inauguration. There, he and Hozuki Gengetsu of the Land of Water nearly escalated their countries' dispute into open conflict. Although neither used their full strength, their clash ended in a draw and established their enduring hostility. 17
His reputation as a Dust Release user, stealth specialist, and flying ninja made him one of the Land of Earth's most dangerous combatants. Yayoi identified him as Ishikawa's follower and speculated that he could become Iwagakure's next Tsuchikage. 17
Over the following year, repeated encounters with Gengetsu left Mu heavily bandaged. While traveling with his student Ōnoki, he joined Yayoi, Kakuzu, and Irori against Uchiha Madara. Mu's Dust Release failed to strike Madara, whose Sharingan saw through Mu's chakra concealment; Madara then critically injured Mu with Susanoo's sword aura. 37 39 40 41
Yayoi saved Mu from his near-fatal injuries. The incident forced Mu to recognize both the limits of his knowledge about the Sharingan and the vast gap between himself and Madara. He later maintained a correspondence and a gradually friendly relationship with Yayoi. 41 50
By the Five Kage Summit, Mu was training Ōnoki in Dust Release and handling Iwagakure's security preparations. He was publicly positioned behind Ishikawa as a prospective Kage successor. 108 111
Following the Samurai Tournament in the Land of Night, Iwagakure formally selected Mu as Ishikawa's successor. With Ishikawa already advanced in age, Mu curtailed his travel and returned home to prepare for his impending tenure as Tsuchikage. 190
During the later war between Iwagakure and Kirigakure, Mu fought his longtime rival Gengetsu in a life-and-death engagement. Gengetsu died in the conflict, while Mu was recovered unconscious with extensive burns, failing organs, and dangerously depleted vitality. Yayoi's medical treatment saved Mu from immediate death, but could not restore the life force he had expended. 268 269 270 By this period, Mu was recognized as Iwagakure's Second Tsuchikage, while Ōnoki took on greater responsibility for stabilizing the village and consolidating the coming succession. 269 270 273
Appearance
Mu is a tall, lean ninja with an impassive expression. After his clashes with Gengetsu, he was seen wrapped almost completely in white bandages, leaving only his eyes exposed. 17 37
- Tall and thin build. 17
- Usually expressionless and difficult to read. 17
- At one point wore white bandages over his body, mouth, and fingers. 37
- Later appeared without the bandages in Iwagakure uniform. 50
- Following the Rock–Mist conflict, he was left with severe burns and extensive physical damage requiring emergency treatment. 269 270
Personality
Mu is restrained, stoic, and pragmatic. Even amid diplomatic confrontations, he generally speaks with measured calm rather than openly displaying his thoughts. 17 50
He is patient with Ōnoki and understands the First Tsuchikage's methods, having himself been similarly subjected to Ishikawa's schemes. 108 However, Mu has little tolerance for Gengetsu's provocations; their rivalry repeatedly devolves into insults and threats despite their willingness to stand down when ordered. 111 156
Madara's defeat left Mu more cautious and aware of the value of intelligence. He openly admitted that his lack of knowledge about the Sharingan had directly contributed to his near death. 41
After his crippling battle with Gengetsu, Mu prioritized peace negotiations and the stabilization of Iwagakure over further warfare, recognizing the limits imposed by his worsening condition. 270 273
Abilities & Skills
Dust Release
Mu pioneered the Kekkei Tōta known as Dust Release, combining Wind, Earth, and Fire nature transformations. It creates a transparent barrier that disintegrates anything caught within it to the atomic level. 17 50
- Dust Release: Detachment of the Primitive World Technique — forms a brilliant, transparent cylindrical barrier capable of reducing its target and surrounding terrain to dust. 39
- Considered a decisive technique against even top-tier opponents if it lands. 39
- Requires accurate targeting; Madara avoided Mu's attack by moving before the technique could connect. 39
- During the rogue-ninja extermination, Mu used Dust Release from concealment to erase numerous fleeing rebels in the island fortress. 157
Dustless Bewildering Cover
Mu developed Dustless Bewildering Cover specifically to support his Dust Release combat style. The secret art conceals both his body and chakra, making ordinary sensory ninja unable to locate him. 41
- Earned him the title “No-Man.” 41
- Can be vaguely tracked by the Byakugan or powerful sensory ninja. 17
- Was countered by Madara's high-level Sharingan Insight, which perceived Mu's chakra pathways despite the concealment. 41
- He maintained the technique while eliminating rogue Iwagakure shinobi during the joint extermination operation, never visibly revealing himself. 157
Flight and Sensory Ability
Mu can hover and fly after using Earth Release, giving him exceptional mobility and evasive capability. He is also an accomplished sensory ninja with strong danger intuition. 17 41
- Uses aerial positioning to locate enemies and prepare Dust Release attacks. 39
- His mobility allowed him to evade Gengetsu's attacks during their later confrontation. 111
Earth Release
Mu is proficient in Earth Release beyond its use in support of Dust Release.
- Earth Release: Swamp of the Underworld — transforms a broad area of ground into a swamp, trapping and interrupting opponents. 111
- He used the technique to swallow Gengetsu halfway into the ground and disrupt the latter's attempted summoning during their Five Kage Summit confrontation. 111
- Ōnoki avoided the worst of Madara's sword aura by using Earth Release to burrow underground, reflecting the tactical use of the element within Mu's circle. 40
Relationships
- Ishikawa — First Tsuchikage and Mu's superior; Mu followed him for years, assisted with Iwagakure's affairs, and was ultimately selected as his successor. 17 108 190
- Ōnoki — student and eventual successor figure; Mu supports his determination to master Dust Release and shares a familiar frustration with Ishikawa's treatment of him. During Mu's coma after the Rock–Mist conflict, Ōnoki held Iwagakure together and led from the front. 40 108 270
- Hozuki Gengetsu — longtime rival from Kirigakure; their personal animosity repeatedly threatened to turn diplomatic gatherings violent before culminating in their life-and-death wartime clash. Gengetsu died in the conflict that left Mu critically weakened. 17 111 156 268 269
- Oda Yayoi — initially a fellow delegate, later an ally and friend; Yayoi saved Mu after Madara nearly killed him, and the two subsequently exchanged letters. Yayoi later treated Mu's catastrophic war injuries and continued their private correspondence. 39 41 50 270
- Senju Tobirama — informed Mu of the Sharingan's Insight ability after Mu's defeat by Madara; later worked alongside him at multinational meetings. 41 156
