The premise is good, but the execution not so much.
As a possession enjoyer, I'm hooked on the premise but left feeling just as I was when I was getting to this anime. Tho, I enjoy every fan interaction in this series. Yes, those are some of the best ones, in any anime. It's the charm of this anime. Not the MC but the SC that fangirling over their oshi.
Oh and also kudos to the one who has the idea to make every episode have a unique outro. It had charm to it and I'm actually enjoy listening to all of the song.
Overall - 5.9
