This show got really popular in the last fall season, it is appealing for a certain part of the comunity that really do like these type of series in which we can fantasize as to what is the root of the arcs presented in the story and it gives us the name of the cause of every problem that will be presented through each arc and it is: Puberty Syndrome.
PS(puberty syndrome) is a distortion of reality in which the individual person sees himself in a situation that goes beyond what can really happen in real life, thus making it fantasy since the playground of the development of the syndrome is the head and mind of the characters and they create the problems unintentionally and go through them searching for a way to defy their limitations and make the way out of all the inconveniences possible.
The story itself centers around a high school guy called Sakuta and his experiences with different kinds of representations of the puberty syndrome through his friends or acquaintances because every time a character has a realization of the syndrome Sakuta is right there for any number reasons going from helping them go through it or trying to find the solution to the problem. Mai sakurajima is a girl that can't be seen by people and seeing that begins using a Bunny girl outfit in order to know if someone can see her, Sakuta is able to see her and that way begins their relationship because being him the only person that can see her makes Mai see him as her only reliable and confident person. The relationship between Mai and Sakuta is well developed in the first arc of the story reaching it's climax in the finale of the arc, after that they behave more like a couple even if they aren't able to be always together because of responsabilities(work mainly) but they still are capable of having valuable time together.
The rest of the characters isn't lackluster either since they have their own problems and realizations of the syndrome. Kaede is Sakuta's sister and a panda loving girl that cares for her brother and had a turnaround because of some events that happened in her school, Futaba is a girl that goes to the same school as sakuta and always gives him explanations supossedly based in analyticis with nonexistent proof, Nodoka is the younger sister of Mai and see her as an example eventhough she despise her because she always saw her as better than erself, Koga is a girl that wants to change the outcome of a certain event that happens in her school and Makinohara Shouko is the first person sakuta had romantic feelings for and seems to always appear in his moments of utmost needs.
The music of the show is passable, it isn't good but it functions for the kind of show that this is. The opening is a good song and the ending along with the ending sequence can be entertaining for a couple of times but it isn't anything worth of praise.
The show had some flaws that kept it from perfection but those didn't really affected the final product all that much, some of these flaws are the lackluster reasons behind the puberty syndrome realizations, the lack of interaction between supporting characters and the nonsensical analytical explanations that Futaba gives everytime Puberty syndrome is mentioned, at the end this anime was a pretty good show with it's own message and did it really well.
Rascal does not dream of bunny girl senpai is an excellent adaptation of a succesfull light novel series that gained a lot of popularity on it's own and made a part of the anime comunity questions what is it's appealing and i will give one reason and one reason only: Bunny girl senpai.
