has just transferred to a prestigious all-girls’ school that happens to share dormitory facilities with two other academies for young ladies. The new surroundings are a lot to take in, but she quickly adapts to life in Strawberry Hall with the help of newfound friends. However, when Nagisa catches the eye of Shizuma Hanazono
, the respected representative of all three schools known as the Étoile, both their lives are forever changed. Bonds beyond mere friendship develop between the two and those around them amidst a school year of heated conflicts, petty jealousies, and crossed boundaries.
Aoi Nagisa transfers to one of the three affiliated all-girl Catholic schools on Astraea Hill, St. Miator’s Girls’ Academy. There, she discovers a community of fellow students entwined in an intricate hierarchy, in which two Etoiles represent the three schools. In order to fit in, Nagisa must go to class, join clubs, and make new friends. Meanwhile, Shizuma Hanazono, the sole Etoile of Astraea Hill, finds herself drawn to this new, exciting transfer student. As Shizuma and Nagisa get to know each other, Shizuma finally decides it is time to face her troubled past.
On Astraea Hill stand 3 prestigious female-only academies known as St. Miatre, Spica, and LeRim; and though the schools are separate, they share a single campus and dormitory. Nagisa Aoi is a 10th grader who has decided to transfer to St. Miatre’s Girls’ Academy. Though her transition has been smooth so far, while exploring the campus Aoi inadvertently falls down a hill, sees the beautiful Shimuza, and promptly (not to mention embarrassingly) faints. Nagisa continues to see Shimuza out and about, but soon discovers that she is the “Etoile” — a well respected girl within all of the schools. With Shizuma taking a liking to the new transfer student Nagisa, secrets of Shizuma’s past will unravel over the coming school year.
