Caged Lovers

A boarding school academy where intelligent girls with attractive looks and figures are gathered.
This academy is a special place unlike any other where an unusual physical exam and curriculum were established.
On the day Chizuru (千鶴 - literally "one thousand cranes") transfers into such an academy, she encounters a girl called Fuyuko…
This is the story of small blessings for the girls who come together through the experience of mutual hardships.
