Looking at the place of emergance on the body, I'd say that Uta possesses either a koukaku or a rinkaku kagune. I think that koukaku would suit Uta more in my opinion, but rinkaku would make more sense as he released more that one blade/tentacle. But then again I don't know much about the apearance of a koukaku as I have only seen Tsukiyama's and Naki's. (I watch the anime)
