Mutiny

While out on patrol, the Saint Nazaire shoots down a wayward Sphere patroller and rescues a group of three escapees. Bringing them on-board, Cortes and the pirates realize too late that the "parents" Jaloa and Artemis are actually Sphere agents transporting a young girl, Celia, as their prisoner.

Lena discovers that Celia is a Seijin, and Jaloa is eventually revealed to be one as well, who wants to replace Diwan as Oslo's second in command.

The rebels find themselves imprisoned on their own ship and must act quickly to free themselves before Oslo and Diwan reach them. With the help of Lena, Celia's powers awaken and together they overcome the two agents in time.
