Spring.

Hoshino Hikari is a new transfer student to the prestigious St. Leanne Girl’s Academy. While her transferring in is quite extraordinary, everyone is more interested in the ritual that takes place before the opening ceremonies.

During this ritual, some students manifest signs of the zodiac, and then are given an angelic title and a blessing. These students are known as the Angels of the Zodiac, and are given the role of bringing fortune to the student body. Hikari, who is trying to not stand out in order to root out the school’s secrets, is bestowed with the grace of Virgo during the ceremony and becomes known as “Exousia”.

“But… but… why me…?”

What is her connection to the other Zodiac? And what are the secrets hidden within the school?
