So, unfortunately, it looks like the series has been discontinued.

Relevant twitter post

From what I got from someone commenting/translating over on another site, the artist feels that the way the plotline/development was going was deviating too much from what their collaborator (the actual creator/owner of the Ouga Saki character) intended her to be, so they're cancelling the series.

I love how the meta commentary in this getting cancelled. The otaku will never go steady with the gyaru.

There was also a matter of the possibility of a v-tuber based on the character, and confusion over direction with that.
