Reiatsu

Biodata

Power Progression

The following records Liu Ziyun’s documented Reiatsu milestones; suppressed readings do not necessarily represent his actual strength.

Properties and Measurement

• Testing: Shin’ō Academy tests applicants’ Reiatsu during enrollment; applicants whose results do not meet the requirements may be turned away 8.
• Strength and quality: Reiatsu can differ in intensity, density and quality. Liu sensed that Aizen’s lieutenant-level Reiatsu had unusually high quality and density 59.
• Perception: Spiritual senses can identify familiar Reiatsu, detect battles and distinguish hostile or Hollow-like auras 193 198 213 267.
• Classes: Reiatsu is described using class levels. A reading can be misleading: Liu concealed Second-Class Candidate Reiatsu at Fifth-Class level 54.
• Higher dimensions: Urahara theorized that a lower-dimensional observer cannot perceive higher-dimensional Reiatsu. Liu later said he could reach that level only in Bankai and had to lower his Reiatsu for others to perceive it 113 269.

Applications

Pressure and Combat

• A powerful release can immobilize opponents and damage surroundings. Liu forced Cirucci Sanderwicci to her knees and cracked the stone beneath her; he later suppressed Yammy in his complete form 258 273.
• Reiatsu can be infused into slashes or condensed into solid attacks such as Liu’s Flying Blade 221.
• Reiatsu can manifest in physical-looking forms, including Liu’s phoenix wings and Aizen’s wing-like plates 112 284.

Movement and Construction

• Users can form Reiatsu footholds to cross the Garganta or stand in midair. Poor control produces unstable platforms, as Ichigo demonstrated on the way to Hueco Mundo 248 249 250.

Healing and Nourishment

• Liu’s Heal consumes his Spiritual Power and lowers his Reiatsu; he cannot continue using it once his Reiatsu falls below a certain point 31.
• Liu fed Reiatsu into the Giant Egg to nourish the woman sealed inside, causing its patterns to brighten and its shell to become transparent 291.

Control and Limitations

• Suppression and concealment: Liu suppressed his Reiatsu to hide his strength. His Black Cloak could conceal both his Reiatsu and movements; Bakudō #26, White Hiding, concealed the Reiatsu of two unconscious Soul Reapers 54 164.
• Barriers: A four-person barrier isolated the Reiatsu fluctuations around Hisana Kuchiki’s treatment, preventing even a captain-level observer outside from sensing them 130.
• Stamina: Sustained techniques consume Reiatsu. Hitsugaya’s prolonged use of Hyōrinmaru drained him during training, and he collapsed after briefly producing a stronger surge 221.
• Backlash: After achieving complete Shikai, Liu’s Reiatsu ran out of control and damaged his soul. Kaidō had limited effect on the damage, and his nearly exhausted Reiatsu required time to recover 58.
• Tempering: Unohana explained that Reiatsu tempering makes the body adapt to its user’s Reiatsu from within, unlike medicine’s external stimulation. Liu’s Reiatsu also slowly repaired his soul during recovery 58.
• Effects on weaker beings: Liu said the Kuchiki Clan’s powerful Reiatsu had worn away at Hisana’s fragile spirit body before her powers awakened. An exceptionally powerful Hollow likewise weakened or killed nearby Hollows through his Reiatsu 130 296.
• Control matters: Liu attributed Ichigo’s oversized Zanpakuto to uncontrolled Reiatsu and taught him to concentrate his power rather than let it spread unchecked 193 194.
