Princess Angelise lives a life of privilege in the Misurugi Empire. In a world where people can use a magic known as Mana, Angelise cannot.

Ange is exiled to Arzenal, and joins a group of Normas to become a soldier. Reluctant from the start, she must adapt and realize she no longer is a princess.

After a deadly battle, Ange decides to pilot Vilkiss, a powerful combat armor known as a Para-mail. Will Ange be able to shake her losses and fight again?

Ange has accepted her new life, but the consequences of her actions in battle have caused conflict with the other Normas.

Ange's arrogance leads to a crash landing, and she wakes up next to an unknown boy. She accepts his help as he mysteriously knows how to repair her damaged Para-mail.

Ange's past catches up with her when Momoka, her maid from the Empire, finds her. Is Ange willing to deal with memories of a harsh past after all she has been through?

Newly appointed Captain Salia forces Ange to learn the importance of teamwork and following orders when a new DRAGON appears.

Festa has arrived, and the Normas get a day to celebrate! Ange's day is interrupted by a message sent to her from Sylvia, her younger sister from the Empire.

Trouble forces Ange, Momoka, and Hilda to leave Arzenal. Hilda heads to the Enderant Union to find her mother, while Ange and Momoka return to the palace to find Sylvia.

Both Hilda and Ange are met with unforeseen betrayals in the places they once called home. The two of them must escape back to Arzenal if they hope to survive.

Arzenal is attacked by three strange Para-mails along with a fleet of DRAGONs. In battle, Ange has a shocking revelation about one of the enemy pilots.

Arzenal is recovering after the battle between the Para-mails and DRAGON fleet. Ange and the others discover a survivor and learn the truth about Mana users and Normas.
