No premiere date announced. The new PV is here. Check out the ANN article for additional information. Synopsis from AniList:
Kamiina Botan is a 20-year-old college student. At the welcome party for the dorm she was assigned to, the dorm leader Ibuki gives her a highball to drink and she becomes tipsy, leading to her involvement with Ibuki from now on… A tipsy teasing girl’s comedy!
I really like the art style of the PV for this one. I doubt that it is reflective of what the show will ultimately look like, but it’s really nice. Almost like animated pastel art.
