Plot
Bunny girls do not live in libraries.
This is simply common sense. And yet, that's exactly where Sakuta runs into one in the wild. More bewildering is who the bunny is: Mai Sakurajima, an older student who attends the same school and is a well-known actress currently on break from industry work. Wanting to find out more about the mystery surrounding Mai and maybe get a little closer to her in the process, Sakuta launches an investigation to figure out what's causing this bunny girl to be invisible and unnoticed by everyone around them.
