Nature and Composition

Chakra is an energy formed by combining Mental Energy and Physical Energy. Its properties vary according to the user's constitution, bloodline, training, and nature transformations. 62

• Uchiha bloodline awakening can increase both the quality and quantity of a user's Chakra in stages. 1
• Mental Energy can give Chakra a pronounced Yin Release nature, enhancing compatible techniques. 62
• Chakra can be refined into elemental techniques, used to reinforce the body, transmitted through weapons or strings, and combined with Natural Energy. 185 203 287

Chakra Natures and Transformations

Basic Nature Transformations

The five fundamental Breathing Techniques correspond to the five basic Chakra natures: wind, lightning, water, fire, and earth. 185

Meikyō originally possessed fire, wind, and lightning natures; after obtaining Wood Release, he also gained water and earth natures. 337

Yin Release and Yang Release

• Yin Release is associated with Mental Energy and can grant special properties to Chakra-based techniques. 62
• Yang Release is associated with bodily vitality and influences the upper limit of Medical Ninjutsu training. 184
• The Uchiha's ocular power is described as the pinnacle of Yin Release, while powerful Yang Release is considered a possible means of restoring Mangekyō ocular power. 184

Yin–Yang Release

Yin–Yang Release is created by fusing Yin Release and Yang Release. It is the foundation of Six Paths Power and can manifest as the black rods used by figures such as Madara, Nagato, and Obito. 310

Component	Source / Function
Indra Chakra	Ultimate Yin Release Chakra; associated with the Uchiha bloodline. 309
Asura Chakra	Ultimate Yang Release Chakra; obtained by Meikyō through Hashirama Cells. 309
Six Paths Power	Formed when Indra Chakra and Asura Chakra fuse. 309

Chakra-Based Systems

Ninjutsu

Ninjutsu uses Chakra to produce practical effects, including elemental attacks, sensory techniques, body enhancement, medical treatment, sealing, and spatial movement.

• Chakra-created Fire Style is not ordinary flame; it can exist in the vacuum of space and is described as possessing plasma-like properties. 337
• Lightning Release can stimulate bodily cells, though improper use risks damaging tissue. 185
• Chakra can be released through the acupoints in the feet to improve aerial mobility when used with Moon Step. 203
• Chakra strings can operate large-scale war puppets and machinery. 340

Genjutsu

Genjutsu can disrupt or control an opponent through Chakra, including interference with another person's Chakra flow. 369

• The Sharingan can perceive and counter genjutsu. 31
• Uchiha Hikari's genjutsu was capable of placing Chakra marks on targets and controlling their minds. 341
• Tobirama Senju's Bringer-of-Darkness Technique was used to disrupt Hashirama Senju's Chakra long enough for him to be sealed. 369

Medical Ninjutsu

Medical Ninjutsu relies on advanced Chakra control and a user's Yang Release aptitude. 184

• Meikyō used Medical Ninjutsu while assisting Tsunade with thoracic surgery on Uchiha Tatsu. 113
• Meikyō later explored Lightning Release body-tempering while relying on Medical Ninjutsu to repair experimental tissue damage. 185

Chakra Modes

Chakra Modes circulate Chakra throughout the body to dramatically improve physical performance.

• Lightning Release Chakra Mode combines multiple Lightning Release transformations to enhance speed, strength, and taijutsu. 206
• Its Lightning Chakra is modified to resemble the body's bioelectricity, allowing sustained cell stimulation with reduced damage. 208
• Meikyō developed his own Lightning Release Chakra Mode and used it against Rōshi's Lava Release Chakra Mode. 220
• Lava Release Chakra Mode covers the user in lava, granting extreme heat, defensive strength, and the ability to melt targets through contact. 220

Senjutsu and Sage Chakra

Natural Energy can be mixed with Chakra at a one-to-two ratio to form Sage Chakra, which can then be stored in the body. 287

• Sage Mode grants powerful sensory abilities by perceiving the world through Natural Energy. 287
• Meikyō used Sage Mode to detect White Zetsu hidden within a range of roughly five kilometers. 221
• Sage Chakra stored in Meikyō's dantian enabled him to manifest the Armored Senju Great Buddha. 305
• Six Paths Senjutsu can combine Six Paths Power with Sage Techniques to create Truth-Seeking Orbs. 405

Kekkei Genkai and Bloodline Net

Kekkei Genkai

Kekkei Genkai can be created by fusing basic Chakra natures. Meikyō identified sixteen possible two-nature combinations. 344

Kekkei Genkai	Chakra Composition	Characteristics
Scorch Release	Fire + Wind	Produces scorching heat; Fire Style serves as the core nature. 344
Boil Release	Water + Fire	Produces scalding mist. 344
Lava Release	Water + Earth	Produces a fluid with water-like properties; Water Style serves as the core nature. 344
Wood Release	Earth + Water	Produces solid plant matter with earth-like properties; Earth Style serves as the core nature. 344

Bloodline Net

The Bloodline Net is described as the endpoint of the Chakra system. Mastering it would make a ninja a Six Paths-level powerhouse. 341

• Meikyō sought to understand and integrate Kekkei Genkai in pursuit of the Bloodline Net. 341 344
• The fusion of three Chakra natures may produce a Kekkei Tōta, such as Dust Release. 344
• Meikyō's copied Dojutsu and techniques allowed him to contend with Madara during their battle. 369

Ocular Chakra and the Sharingan

The Sharingan is an Uchiha bloodline ability awakened when intense emotional shock produces special energy in the brain that stimulates the optic nerves. 279

• Keeping the Sharingan active consumes Chakra; Meikyō's ten-year-old body initially could not sustain it for long. 1
• The Mangekyō Sharingan consumes ocular power and strains both the eyes and body, potentially causing blindness through repeated use. 142 279
• The Third Stage Susanoo imposed a severe burden on Meikyō's ocular power and body, causing bloody tears during battle. 171
• The Eternal Mangekyō Sharingan surpasses the Mangekyō by eliminating its ocular-power flaw and improving ocular-power quality. 282

Notable Chakra Applications

• Chakra Metal — Chakra-infused weapons are rare treasures; Ama-no-Ohabari is identified as Meikyō's Chakra weapon. 204
• Chakra Strings — Used to control puppets and the planned super-giant war puppet. 340
• Chakra Suppression — Chakra can be disrupted through genjutsu or depleted through extreme techniques such as the Reaper Death Seal. 369
• Chakra Absorption — Madara's God Tree was capable of draining Chakra from people across the Ninja World. 369
• Chakra Sensing — Sage Mode can detect hidden presences, while advanced sensory techniques can detect Chakra over dozens of kilometers. 221 304
