I was excited to have this happen because it sheds a bit of light on some of the backstory of Mika, Jenny, and the twins' world! Gods/goddesses there may be worshipped (or at least recognized) between species/religions, and Arens and Zephane are a couple well-known dieties. This is likely because multiple figures usually represent certain elements - for example, Arens is a looked to as a war goddess, but certainly not the only by far!
The lack of focus on the girl is because nobody knows who she is or where she came from, what she looks like. Anything. The gender is presumed for quite some time, but no one actually knows where it came up.
So glad the last panel called for colour - that's probably a pixie or fairy of some kind on the left. And anybody guess that lady's costume there? ;0 THINK VIDEO GAMES. (hint probably isn't needed..)
The spirits there are likely real, magicked by Jenny and called closer so people can see what she's talking about. In their world, spirits differ from ghosts/dead souls, there are magical spirits who never have physical bodies but exist all the same invisible around the world. Yeap.
