This anime wasn't really on our list but once we started we couldn't stop. Sakuta Azusagawa, a second-year student at a high school near Enoshima, crosses paths one day with a Bunny girl in the library. Intrigued, Sakuta looks closer and realizes it is a senior classmate of his, Mai Sakurajima, who is a famous child actress on hiatus. Oddly enough, Sakuta is the only person in the library that can see her. She has become invisible to everyone. Sakuta agrees to help her find out why no one can see her and how to fix it. An adventure has begun and we can't look away, you shouldn't either.
