The official website for the television anime of Hinowa Kōzuki’s Yōkai Apāto no Yūga na Nichijō (Refined Daily Life at the Supernatural Entity Apartment) light novel series posted a teaser video and key visual on Wednesday.
Kōzuki launched the light novel series in 2003, and concluded it in 2009 with 10 volumes (and a later side-story collection in 2013).
Kadokawa republished the 10 novels in 2008-2014, and published two spinoff novels for the series in 2009 and 2012.
