Out of sight, out of mind!
Bunny girls do not live in libraries. This is simply common sense. And
yet, that's exactly where Sakuta finds one in the wild. More bewildering
is who the bunny girl is: Mai Sakurajima, a girl one year older than
Sakuta, famous at their school for her acting career even though she's
currently on break. To top it all off, it seems like no one else in the
library can see Mai at all, no matter what she does or...wears. Wanting
to find out more about this mystery and maybe get a little closer to
this beautiful upperclassman in the process, Sakuta launches an
investigation to discover why an unforgettable bunny girl keeps becoming
totally invisible.
