-Hauenkua and Hien are dead thanks to Hakuoro. Genjimaru got one-shotted/vaporized (with gibs) by Dii. Kuuya seems to have lost it after seeing what was left of Genjimaru, including his eyepatch.
-Dii calls out Mutsumi from Kamyu, transforming her. Mutsumi has no problems handling Hakuoro’s monster form, and refers to Dii as her father. At the very end, as Mutsumi and Dii are flying away, she asks why Hakuoro didn’t choose her and says “bye-bye” to her other father.
-With this, the ED image makes a bit more sense. I would guess now that the blue one is Hakuoro, the red one is Dii (the two halves of Witsuarunemitea), and Mutsumi/Kamyu is the bird in the middle.
