Shinigami in the Ninja World

"Is 'Ashura' a Kekkei Genkai?"

Naruto had initially thought so.

The Uzumaki clan was known for their powerful life force and vitality. As a descendant of 'Ashura,' it seemed logical that awakening some ancestral power could grant him access to unique energy that amplified his abilities. It made sense, even if occurrences like this were extremely rare and unrecorded in Uzumaki clan history.

But then, it turned out that Hashirama Senju had it too.

Kekkei Genkai generally fall into two categories.

One is relatively conventional, involving a type of chakra with a unique attribute, like 'Lava Release' or 'Storm Release.' These can be inherited through bloodlines, but they can also be mastered by exceptionally talented individuals who learn to combine and transform two types of chakra.

The other type involves special abilities, such as the 'Sharingan,' 'Byakugan,' or 'Shikotsumyaku.' These Kekkei Genkai have strong familial traits and can only be wielded by those with the specific bloodline.

'Ashura' seemed more like the latter.

But if that were the case, why did two different bloodlines with distinct surnames both have access to the same power?
