Fuku struggles to manage the pressure of battle, prompting Kiriko to propose a different approach for operating the Kamidake II. Believing she is ignored and rejected by the crew, with Seina being the only exception, Fuku decides to leave. She departs aboard the Kamidake II, taking a reluctant Seina along as her only companion. However, their escape is interrupted when space pirates launch an assault on the vessel. The situation quickly escalates, requiring Fuku to step up and utilize her skills to defend the ship against the attackers, proving her value despite her earlier feelings of isolation.
