At her grandmother's request, Mari Wakatake grudgingly begins attending the Kaiho Academy. Upon her arrival, the headmaster is informed that five years ago, Mari was in an accident and lost all of her memories. Mari is shown around the school by Michiko Kozuki.

Hagino is needed back on her ship, Blue, so she leaves the school. Her absence is not scrutinized by the other students, due to a scandal arising between the headmaster and Mari's homeroom teacher. Mari, on the other hand, can not stop wondering about Hagino. After class, Mari and Michiko take part in the monthly student cooking session, but Mari's poor culinary skills spells disaster.

On board Blue, Hagino delivers her report to Master Commander Shibariel, who calls her Ekaril. Hagino explains that there was a malfunction in the ship's Emiru Force Drive, which knocked out communications and caused the accident on Kamioki Island, of which, Mari was the only survivor.

Hagino and Tsubael explain the situation to Mari. Shibariel has sent another ship to attack Blue for Hagino's defiance and refusal to hand over Mari. Blue barely makes it through the attack, but Tsubael is able to do extensive damage to the other ship.
