Background

Soji was originally Xie Zongqi, a university student from Earth. After transmigrating, he inherited the memories and identity of Hyuga Soji, sole heir to the third lineage of the Hyuga Clan’s Main Family. His father had died in the First Great Ninja War, while his mother died shortly after his birth; he was raised by his grandfather, Hyuga Kumokawa. Born in Konoha Year 23, he awakened the Byakugan at five years old. 1

Kumokawa trained Soji rigorously in Gentle Fist, ninja fundamentals, tools, and the Academy’s Three Body Techniques. By Konoha Year 29, Soji had already mastered the Transformation, Clone, Substitution, Escape, and Invisibility Techniques, as well as the Eight Trigrams Thirty-Two Palms. He regularly sparred with Hyuga Hiashi and Hizashi, though he initially lost every match. 10

Although he benefited from Main Family status, Soji disliked the Hyuga Clan’s hierarchy and was disgusted when Kumokawa taught him the incantation used to activate the Caged Bird Seal. He resolved not to use it except under exceptional circumstances. 10

During his time operating in Kirigakure under the identity of Mizuki Ember, Soji developed close ties with the Yuki and Kaguya clans. He sought the Kaguya Clan’s Shikotsumyaku to increase his potential and pursue the Tenseigan, then honored his agreement by developing serum for the Kaguya Clan’s Bloodline Disease before returning to Konoha. 113 131 135

Appearance

Soji normally presents himself as a composed Hyuga man with pale Byakugan. When acting as Mizuki Ember, he wears a carved Ice Mask and a luxurious snow-white robe to conceal his identity. 107 123

• Sage Mode — waist-length snow-white hair and a snowflake mark on his forehead. 235
• Evolved Byakugan — can manifest as ordinary white eyes, one white eye paired with a yellow or purple eye, or a yellow left eye and purple right eye. 421
• Kekkei Mōra form — develops a forehead fissure containing a crimson Nine Tomoe Rinne Sharingan. 1558
• Later evolution — his Nine Tomoe Rinne Sharingan turns white after he breaks free from Kaguya Otsutsuki’s bloodline influence. 1719 1720
• Flight — can form massive ice wings from his back. 490

Personality

Soji is pragmatic, strategic, and deeply conscious of the dangers hidden behind political ideals. He prefers avoiding attention, often presenting Hyuga Soji as an ordinary, idle Main Family member while reserving Ice Release, Shikotsumyaku, and Sage Art for Mizuki Ember. 405 406

Despite calling himself lazy and frequently avoiding work, he trains obsessively when a goal concerns survival, his clan, or the people he values. He is willing to make severe decisions against traitors, but distinguishes between enemies who deserve death and people who can be handled peacefully. 197 409

He can be irreverent, teasing, and mischievous with friends—particularly Uchiha Homura and Kakashi—but is fiercely loyal to Konoha, the Hyuga Clan, and his students. 1159 1205 His long-term goal is peace through a multinational academy system and mutual understanding between the Ninja World’s younger generations rather than through force alone. 567

Abilities & Skills

Byakugan and Gentle Fist

Soji’s Byakugan evolves far beyond standard Hyuga capabilities, enhancing his perception, chakra control, Gentle Fist, and unique ocular techniques.

• His post-rebirth Byakugan can observe up to ten kilometers away and perceive microscopic details. 308
• Intimidation releases an oppressive force capable of incapacitating or killing weaker opponents; it annihilates more than thirty Kumogakure shinobi in a single use. 131 395
• Void Strike gains six forms after his second evolution and is compared to a weakened form of Kaguya’s Eighty Gods Vacuum Attack. 309 349
• Mind-reading reads a target’s current thoughts, but can be countered by overwhelming speed or power. 309
• Dovanten is his left-eye illusion technique; when paired with mind-reading, it lets him rapidly extract information from a target. 409
• His third evolution grants a Byakugan-based Illusion Technique, as well as enhanced Repulsion Palm and Absorbing Palm. 356
• He develops an ultimate Gentle Fist technique powerful enough that, in his own estimation, a Byakugan-only Soji could defeat Mizuki Ember using Ice Release, Shikotsumyaku, and Sage Art. 406

Ice Release

Soji combines Water and Wind chakra into Ice Release and develops it into his principal elemental arsenal.

• Can create ice weapons, barriers, prisons, tombs, seals, dragons, and terrain-spanning frozen environments. 149 488 490
• Snowfall Technique changes the local weather and creates conditions suitable for gathering Natural Energy. 273 481
• Can move through ice, create Ice Wings for sustained flight, and perform simple techniques without hand seals. 490 509 410
• His Ice Release can be fused with Yin Release, though an early attempt at Ice Tomb backfires and inflicts soul frostbite, leaving him extremely sensitive to cold while recovering. 196 197
• At its peak, he masters Freeze Time-space, a rule-level power that freezes the time-space of all Konoha. 1719

Sage Mode

Soji developed a unique Sage Mode in the Land of Snow rather than training in one of the Three Great Sage Regions.

• Greatly enhances his physical strength and ninjutsu through Sage Art Chakra. 350
• Initially requires hours to enter under normal conditions; Snowfall can reduce the process to roughly one minute. 410
• Can enter Sage Mode instantly in naturally snowy regions such as the Land of Snow and Land of Iron. 410
• His Sage Mode is central to his highest pre-Six Paths combat output. 481

Shikotsumyaku

Soji acquires the Kaguya Clan’s Corpse Bone Pulse through genetic experimentation and later fully awakens it by injecting combined Hyuga gene fluid.

• Produces bone bullets, blades, spikes, and defensive structures. 486 488
• His ice-blue bone spikes combine Ice Release, Yin Release, and Shikotsumyaku. 333
• His Shikotsumyaku disrupts the chakra of any target struck by it. 349
• Awakening it doubles his chakra reserves and improves the precision of his body and chakra control to 100%. 308

Tenseigan and Chakra Mastery

Soji’s Byakugan develops into a Tenseigan prototype through increasingly pure Hyuga, Kaguya, and Moon Otsutsuki bloodlines.

• Completes all seven elemental chakras: Water, Fire, Earth, Wind, Lightning, Yin, and Yang. 1171
• Gains the ability to fuse Kekkei Genkai with relative ease after understanding the nature of chakra. 1171
• Uses Truth-Seeking Orbs defensively against Otsutsuki attacks. 1244
• Possesses gravity and repulsion techniques without relying on the Rinnegan. 488

Kekkei Mōra and Nine Tomoe Rinne Sharingan

After consuming the God Tree fruit, Soji reaches Kekkei Mōra and becomes a being comparable to Kaguya Otsutsuki.

• Gains immortality; only sealing can permanently restrain him. 1558
• Uses Yomotsu Hirasaka to cross the Ninja World instantly. 1558
• Masters Eighty Gods Vacuum Attack and All-Killing Ash Bones; he avoids using the latter near allies because a hit guarantees death. 1559
• Gains access to Infinite Tsukuyomi, Nature Assimilation, and Six Paths: Chibaku Tensei. 1559
• Can perform the Outer Path: Reanimation Jutsu, though it has considerable chakra consumption. 1559
• Develops Holographic Eye and No Longer Human after studying the Divine Arts of Ada and Dimon. 1720
• His Sumeru Myriad Manifestations lets him revive from death by returning a living version of himself from the immediate past to the present. 1745

Research, Medicine, and Sealing

Soji is an accomplished researcher whose experiments drive much of his growth and support his allies.

• Develops serum to treat the Kaguya Clan’s Bloodline Disease. 135
• Researches Hyuga genetic fragments, Caged Bird improvements, and methods to advance the Byakugan. 296 552
• Performs surgery restoring Uchiha Itachi’s vision after Mangekyo Sharingan damage. 955

Equipment / Weapons / Items
