Truth Seeking Balls are a Kekkai Genkai

[90sKids98]

That is attained by those who become the jinchuriki of the juubi.

Kekkai Genkais are technically a combination of the main nature elements, and the Dust Style is stated as an advanced form of a kekkai genkai (kekkai tota). So who is to say TSB isnt?

 

[slayerdanger]

It's a bijuu skill not a kekkai genkai, also not all kekkai genkais are nature kekkai genkai, for example juugo's nature energy gathering kekkai genkai and kimimaro's bone KKG.

Good! Excellent!

It's not a KKG since it's not a bloodline limit.

 

[Seventh Sama]

It's a bijuu skill like how naruto has that negative emotion sensing power from being kurama's jin.

What everyone above said.
Its comprised of fire, earth, wind and water elements along with senjutsu which utilize the Yin-Yang nature

 

[Xāvî1]

No they are not KKG
