| Name | Kekkei Mōra (血继罗网) |
| Type | High-order chakra-nature fusion classification |
| First Appearance | 52 |
Classification
Kekkei Mōra is described as the result of fusing four or more Chakra natures. The stated hierarchy places it above Kekkei Tōta, which requires three natures, and Kekkei Genkai, which requires two 52.
| Fusion level | Classification | Notes |
|---|---|---|
| Two Chakra natures | Kekkei Genkai | Requires bloodline genes to reconcile otherwise incompatible natures 52 |
| Three Chakra natures | Kekkei Tōta | Higher-order nature fusion 52 |
| Four or more Chakra natures | Kekkei Mōra | The stated threshold for the classification 52 |
A technique using numerous chakra natures is not automatically Kekkei Mōra. Uchiha Gen's Five Release Rasengan uses five incompatible natures to trigger fission rather than a stabilized bloodline fusion, and is explicitly stated not to belong to any of the three classifications 52.
Documented Applications
Uchiha Shell
Uchiha Gen uses Kekkei Mōra: Uchiha Shell to create a thin, rainbow-colored membrane around his body. The barrier expands against an influx of strong acid and prevents it from reaching him 89.
- Forms a multicolored, bubble-like defensive layer around the user.
- Withstands the corrosive acid of Shikkotsu Forest without allowing it to seep through 89.
- Its exact component Chakra natures are not identified.
Five-Nature Fusion Beyond the Standard Threshold
Little Kuro attempts to combine Chakra from all five elemental natures, later noted to include Yin–Yang properties. Gen judges the process to have exceeded his own ability to fuse four transformations and describes it as beyond the concept of Kekkei Mōra 85.
- The incomplete attack resembles a Tailed Beast Bomb but forms too slowly for practical combat 85.
- Its unstable detonation creates spatial turbulence that erases objects entering the resulting crater 85.
- Gen concludes that its destructive force reached the level of shattering space 85.
- Kuro exhausts all stored Chakra during the attempt and requires months of recovery 85.
- Gen notes that fusion of five natures plus Yin–Yang would produce a Truth-Seeking Orb, though Kuro's attack remains incomplete 85.
Known Non-Example
| Technique | Why it is not Kekkei Mōra | Chapter |
|---|---|---|
| Five Release Rasengan | Uses five Chakra natures, but their incompatibility is deliberately used to cause fission rather than forming a stable bloodline fusion. | 52 |
