Premieres sometime in 2024. Check out the Crunchyroll article for additional cast/staff info. The main cast announcement is that Rie Takahashi will be voicing the MC. Synopsis from AniList:
Alina signed up to be a receptionist for the Adventurers Guild but her dream gig is an overtime nightmare! To save herself from paperwork, she secretly beats down monsters herself.
Ok this sounds like fun. I feel like the receptionist lady NPC is in every series, making her the lead should be interesting.
