How is that Mokou?
Perhaps the long-beak one could be Sagume(heron)?

Hot damn, now that's an amazing pic!

There are two things that could make it even better, though: Utsuho having Yatagarasu's third leg and Marisa that should have been a magpie due to her color scheme and her habit of steal... indefinitely borrowing.

I think Mokou is meant to be the bird (phoenix?) in the upper right.

The long beaked one is a crested ibis and according to Pixiv tags is Tokiko.

And of course Remilia is cowering again.

It's daylight. Of course she'd be cowering from the sun.
