OVA
Description
Louise Fort Drake serves as a member of the Space Defense Force's Sirius Platoon aboard the Galaxy Railways locomotive Big One, where she is the sole human female crew member. Daughter of President Drake, leader of the Clarious Stellar Cluster, she endured a strained childhood relationship due to his cold and unloving demeanor, leading to disagreements over his detached leadership. This conflict shifted when she saved his life, prompting his recognition of past mistakes.

Initially clashing with fellow crew member Manabu Yuuki, their bond evolves into friendship. Romantic tension develops throughout their interactions, culminating in an official relationship by the end of the first season. Professionally, Louise is headstrong yet dutiful, typically following orders even when personally opposed. She blends strong leadership with analytical precision and logical problem-solving, balancing duty with fervent loyalty to her comrades.

In the OVA "A Letter from the Abandoned Planet," she joins the Sirius Platoon's mission aiding the crashed Galaxy Express 999 on Herise. Across all missions and storylines, she remains dedicated to protecting others and upholding Space Defense Force responsibilities.
