Warning: This review may contain spoilers.
For starters, to y'all that think this is really going to be a Bunny Girl senpai anime, well it's not wrong. But sadly the story has basically nothing to do with Bunny Girl (there are literally only 2 moments where the senpai wears the costume). The anime's title is just not right, and misleading to be exact. It should've been something related to a popular figure. The point is, if you're looking for ecchi scenes, this isn't the right place. Or even if you're looking for a literal bunny girl, it won't be what you think it'll be.
Animations: MAGNIFICENT!
Breathtaking animations for real, it's definitely one of the best animations in 2018. It's really good that it could make you want to see more and more! CloverWorks really nailed this one.
Soundtracks: Unforgettable
Well, although the soundtracks are only the opening and ending theme, but those soundtracks are just pure masterpiece ngl. Even I knew both the OP and ED theme before start watching it. It's just that great!
Plot/Story: Great
First of all, this anime will literally make your feelings, emotions, all mixed up. You'll literally feel all human emotions in just 13 episodes. Just so you know, the anime is more towards Supernatural (Mystery) and Drama. That means, if you like thinking, solving mysteries, this'll be a perfect fit for you. Oh yeah, I also think that it has a Comedic side too, which some people might find it funny (including me). Although it's not realistic, there are quite a lot of relatable moments in the story. Honestly, it's not what I wanted. I thought it's going to turn out to be like the average Romance in School anime. But SOMEHOW I really enjoyed it MORE than what I expected.
The plot is actually crystal clear and quite simple, even though people are saying: "I don't understand what I'm watching" or so. I mean like, hey, it's about mysteries. And because of that, it's prone to "plot holes". Huge respect to the author for making ONLY a few plot holes, if not unsolved cases.
Character Development: Superb
I forgot to mention, the character development is crazy! Episode by episode, you'll know about the characters more (their personalities).
OVERALL: 9/10
It's definitely a must watch anime.
