Background

Xia Mu transmigrated into the Naruto world and awakened memories of his previous life at the age of six. Soon afterward, he discovered both his Senju bloodline and the Infinite Gravity Training Room, a personal training aid that supplied resources and a Special Laboratory State. He immediately strengthened his bloodline, prioritizing chakra reserves, survival, and personal growth in a dangerous world. 1

Despite already meeting the practical requirements for graduation, Xia Mu enrolled in the Ninja Academy to learn its academic and shinobi fundamentals. He initially kept a low profile, describing himself as having no particular likes, dislikes, or dream, while privately studying chakra control, one-handed seals, and new techniques. 2 3

His earliest close friendship was with Shino Aburame, whom he approached sincerely and supported through shared training. He later met Tenten through her family's ninja-tool shop, sold her his designs, and began regularly coaching her. Their relationship developed into an open romance after he used Lightning Release to stimulate her body and improve her chakra growth. 4 10 16 18

Appearance

Xia Mu was initially described as clean-cut but not notably handsome, allowing him to avoid attention at the Academy. He appears slender while clothed, though he is physically muscular from constant gravity and taijutsu training. 3 112

• Trained physique concealed beneath an otherwise unremarkable build. 112
• Often carries ninja tools, marked kunai, and his Thousand Blades Demon Blade during combat. 64 80
• Became widely recognized by the title Konoha's Demon Blade after his battlefield exploits. 64

Personality

Xia Mu is analytical, pragmatic, and highly self-directed. He studies fundamentals rather than relying solely on talent, experiments constantly with chakra applications, and adapts techniques creatively in battle. He initially avoids unnecessary attention, but stops concealing his ability once doing so would improve his prospects, protect his companions, or secure better instruction. 3 18 25

He is generous with useful knowledge. Xia Mu teaches Shino, Tenten, Tatsuya Yamashiro, and Megumi Kato techniques suited to their individual strengths, believing that stronger allies make missions safer for everyone. 16 17 37

His main motivation for pursuing strength is protecting the people important to him. This includes Tenten, his friends, his teammates, and Konoha; he is willing to confront powerful enemies when they endanger them. 25 26 117

Abilities & Skills

Infinite Gravity Training Room

Xia Mu's golden finger grants access to a gravity-based training space and a monthly Special Laboratory State. It provides conditions for extreme physical conditioning, technique research, and experimentation that would otherwise be too dangerous. 1 29

• Increased gravity training from triple gravity in his early Academy years to fifteen times gravity later on. 13 58
• The Special Laboratory is entered on the first day of each month and provides unlimited stamina and chakra. 29
• Used the laboratory to develop techniques, test Flying Thunder God, attempt Sage Mode, and fuse chakra natures. 29 58 91 96
• Its supplied food is tasteless and does not replace his need for ordinary meals. 5

Senju Physiology and Chakra Control

His 80%-pure Senju bloodline gives Xia Mu unusually large chakra reserves and exceptional learning speed. 1 2

• Chakra Threads — chakra-based threads intended for further enhancement through chakra natures. 8
• Chakra-generated arms — creates controllable extra limbs and hands that can form hand seals while his real hands remain free. 16

• Tempest Kick — releases cutting air slashes through kicks. 17
• Paper Body — flattens his body into a paper-thin form to evade attacks, including Neji's Eight Trigrams Palms. 27
• Tekkai and Finger Pistol — require Iron Transformation training; using Iron Transformation for more than a minute can injure the body. 17

Eight Gates

After passing Might Guy's test, Xia Mu received the Eight Gates manual and pushed the technique aggressively through Special Laboratory training. 26 28

• Opened the first six gates. 28
• Learned Morning Peacock and Daytime Tiger. 28
• Combines the gates with Six Powers and swordsmanship for explosive speed and striking force. 37

• Uses hidden formulas to evade detection during reconnaissance. 80
• Returned instantly from distant missions and battle zones. 64 99

Sage Mode

Xia Mu researched Sage Mode after negotiating access to the Senju Clan Library and consulting Katsuyu. 83 91

• Tested natural-energy absorption through a Shadow Clone to reduce the risk of petrification. 83
• Can activate Sage Mode quickly only in natural-energy-rich environments. 91
• Under normal conditions, activation takes more than a minute and the mode lasts approximately four to five minutes. 91
• Treats it as a trump card because of its slow activation and short duration. 91

Kekkei Genkai and Large-Scale Techniques

Story Role / Major Arcs

Academy Years

Xia Mu enters the Academy to gain formal shinobi knowledge while secretly exploiting the Gravity Training Room. He befriends Shino, begins training Tenten, develops one-handed seals and custom techniques, and gradually abandons his initial low-profile approach as his strength rises. 2 4 16 25

Team 9 and the Chunin Exams

After graduation, Xia Mu joins Team 9 under Aoba Yamashiro with Tatsuya and Megumi. He functions as the team's practical organizer and instructor, helping his teammates build techniques and prepare for dangerous missions. 36 37

During the Chunin Exams, he identifies Orochimaru's disguise, confronts him, and later forcefully defeats him when Team 7 and Might Guy's Team are endangered. His actions establish the reputation of Konoha's Demon Blade. 46 47 55 64

Akatsuki Investigations

Tsunade increasingly assigns Xia Mu high-level reconnaissance work because of his mobility, combat strength, and judgment. He investigates Deidara and Sasori, identifies the Land of Rain as Akatsuki's base region, and later protects Fuu from Itachi and Kisame. 91 97 99 103

He also rescues Fuu from Obito's attack, further cementing Akatsuki's view of him as a major threat. 117 118

Fourth Shinobi World War

During the war, Xia Mu confronts Raikage Ai, pressures the Hidden Cloud leadership into participating in the Five Kage Summit, and becomes a key Allied Forces combatant. 131 159 160
