Looking for a manga; Female Demon Lord and the Hero got stuck in an alternate empty dimension

[RitoTheLittle]

As the title says, it's a somewhat old manga, last I recall reading it around 8-9 years ago. It was a semi slice-of-life comedy with the Demon Lord and her entourage and the Hero party getting stuck and now "surviving" in this empty dimension. I think the scanlations at the time only had around 8 chapters ish?
But yeah, thanks for the help <o
