This is Kurama Yang Chakra Mode. This is NaruKura (Naruto & Kurama mixed) Yang Chakra Mode. This is NaruTB (Naruto & all Tailed Beast mixed) Chakra Mode, plus Six Paths Sage Mode. ''Don't forget that Kurama Yang Chakra is in Madara, so this mode only has Kurama Yin Chakra. This is Kurama Chakra Mode, plus Toad Sage Mode. They didn't want to spoil the NaruTB Chakra Mode and the Six Paths Sage Mode, as they are not shown in the anime yet. This is NaruKura Chakra Mode, plus Six Paths Sage Mode. This is Kurama Chakra Mode, plus Six Paths Sage Mode. This is NaruTB Chakra Mode, plus Six Paths Sage Mode.

My opinion: In Boruto, Naruto thought Kurama Chakra Mode was enough to beat Momo, but then he was wrong, so he uses NaruKura Chakra Mode later.
