So here's my thinking. Jigen is a human, plain and simple. This new Ten-Tails is the other Otsutsuki, imprisoned for eating the chakra fruit. I think he's paired with Kaguya because both of them ate the fruit directly. Jigen's Kama allows him to absorb the Ten-Tails chakra in (relatively) small amounts, turning him into something akin to the Otsutsuki's original form. At some point he's planning to, or agreed to, absorb all the Ten-Tails power, essentially freeing the Otsutsuki from his prison.

The question then becomes where Jigen got his Kama. I'd assume it has something to do with the damaged parts of the wall, which would represent Urashiki and someone else (potentially the one who gave Jigen the Kama). Momoshiki wants Boruto to absorb more chakra with his Kama so he can be revived.

I think the anime arcs have also been leading to this. First an arc about Onoki making artificial humans with the help of a mysterious scientist, likely connected to Kara and their attempts to make another "vessel". Then an arc about the curse marks, which we know Orochimaru made to prepare his own "vessels" using his chakra.

If there is a connection to the Strength of a Hundred Seal, I thinks it's mainly to do with slowly collecting chakra for use later.
