The Chihaya with the eyepatch wasn’t shown to be decapitated before the lights went out.

Unfortunately, the series is labeled as completed despite resolving absolutely nothing. I can't even imagine how it would have ended though, but probably not on a happy note.

I was surprised to see it end not with her getting together with the photography club senpai, but with a poly relationship. Unfortunately, the ending was so obviously rushed that everything seems out of left field.
