I have literally watched six hours of footage, completed a further two hours of reading, and spent a chunk of today writing instead of making queues, but the God of Day has been officially added to the roster. You can read about her here (or here if on mobile).
By default, her setting will be after the gods concluded their council meeting. Once morning rose, she fled to the human world and hides there to complete her duties, disguised as a young woman named Hina who offers shelter (similar to a B&B) in her home when evening falls. This will not only allow for the opportunity for better interactions, but it will allow her to actually make friends for the first time ever.
If interacting with her before this meeting, she can be referred to as ‘Day’ or ‘A.materasu’.
