Mari Wakatake (voiced by
Akiko Yajima) is the lone survivor of a mysterious disaster that complete wiped
out the small island she was from. Making matters difficult, she has no memories from before or of the
event. Five years have passed and Mari is transferring into the prestigious girl’s school,
Kaiho Academy; a transition she isn’t thrilled about and makes no effort hiding her distain.
Mari’s first interactions with her fellow students are strained, but there's one girl who seems to always strike a nerve; Hagino
Senkoji (voiced by Miyuki Sawashiro).
Despite the two starting off
on the wrong foot, Mari and Hagino cannot help but feel some kind
of connection between them. Things then start to go from complicated to other
worldly when Mari discovers Hagino isn’t quite who she claims.
It turns out that Hagino is
the commander of the alien battleship Blue, and was part of a reconnaissance
mission for an incoming invasion. Yet Hagino has seemingly turned
against her comrades and is doing whatever she can to protect the Earth; a
decision that was a direct result of the tragedy on Mari’s home
island.
The two girls struggle to
open up to their friends and each other, but that cannot deny their
feelings
