Kekkei tōta (血継淘汰, literally meaning: Bloodline Selection) is an advanced branch of jutsu that is more advanced than the jutsu class of kekkei genkai. The only known example is Dust Release, a combination of three different nature transformations — earth, wind, and fire.
- In the anime, it is stated that kekkei tōta users have an affinity for all three of the natures they can combine.
- In Gaara Hiden: A Sandstorm Mirage, it was stated that by combining two different kekkei genkai — in this case Lava and Steel Release — in one attack, the resulting attack would be a "pseudo-kekkei tōta" (擬似血継淘汰, Giji Kekkei Tōta).
