We don't know why he absorbed the chakra. And his Icon on the rock is clearly there to represent him. He had a horn at some point in the past, hence the icon having a single horn. Obviously something happened to him or his power. As far as we can tell based on evidence, he is and was always Kaguya's partner. If anything, its possible he got the Karma from that "missing" Otsutsuki for plot purposes, seeing as we've never seen Urashiki with a partner, but so far, only Otsutsuki have appeared. Jiren is the exception because we don't know exactly what he is, but if the diagram is anything to go by, he came with Kaguya.

And that anime version of Kaguya's Earth story is just that - Anime. The manga iirc never tried to fill any of that in and its obvious that the partner thing was inspired by the Boruto movie and the mangaka for the Boruto series, so of course we didn't know about the partner thing in the past.

Also, we know that you can get the Karma from an Otsutsuki passing it onto you after they die. He didn't kill this new Ten-Tails so I find it hard to believe that it gave Karma to Jigen and was her partner, as it isn't dead.
