The series is an anime now! This is its opening credits. It looks like four episodes have been aired so far, and I think this might be one of the few current anime series that hasn't been delayed by the pandemic. It's streaming legally with English subtitles on Crunchyroll. The few clips I've seen make me think it probably sits somewhere between the original novels (terrible but with fun aspects) and the manga (so much fun but inherited the novels' weird pacing) in terms of overall quality.
