Rascal Does Not Dream of Bunny Girl Senpai

Sakuta Azusagawa, a second-year student at a high school near Enoshima, meets several girls that are experiencing this “puberty syndrome.” For instance, he meets a wild bunny girl in the library. She turns out to be an actress on hiatus, Mai Sakurajima, who is also his senior at the school. For some reason, no one else can see this enchanting girl. How did she become invisible…

While looking for the cause of Mai's Adolescence Syndrome, Sakuta ends up scheduling a date with Mai. Sakuta tries to help out a lost little girl on his way towards Fujisawa Station. But, he is misunderstood to be a perverted maniac by another girl, and he ends up arriving late to meet Mai. They proceed with their date, but Mai changes their destination and takes Sakuta to Shichirigahama Beach...

Even after leaving Fujisawa for Ogaki, not one person remembered anything about Mai Sakurajima. Sakuta hears of a theory that losing memories concerning Mai is based on a certain action taken, and struggles so that he doesn't lose his memories of her. And seeing Sakuta act as such, Mai makes a certain decision of her own as well...

Soon after Mai's "puberty syndrome" is resolved, Sakuta encounters another strange phenomenon without respite. Day after day, it is the same day for Sakuta and there is no tomorrow. When he consults Rio, she raises the possibility of "Laplace's demon" -- that someone may be repeating and redoing a day.

Because of the misunderstanding that she was dating Sakuta, Tomoe is able to resolve the agonizing situation of being asked out by the guy her friend is in love with. She pleads with Sakuta to continue acting like they are dating. Sakuta could not leave Tomoe alone as she feared that she would lose her presence within her class. So, he reluctantly agrees to play the role of Tomoe's fake boyfriend.

It is now the last day of the first term, the promised day when pretending to be dating Tomoe ends. It seems as though everything has finally been resolved, but...
