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 girl is: Mai Sakurajima, an upperclassman and well-known actress currently taking a 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 making this bunny girl invisible to everyone around them.
For readers ages 16 and up.
