Description
Shōko Kobayashimaru (小林丸 翔子) is a Hakuoh Academy student and member of its Space Yacht Club. She possesses grey eyes and black hair styled in a bobcut, typically covering the left side of her face. She wears the standard Hakuoh Academy uniform, adding a green Yacht Club hoodie during club activities and a blue police officer costume for specific missions like the raid on the Princess Apricot.

Her personality is slightly deadpan, with fellow club member Lynn Lambretta observing her relative maturity. Her background before joining the yacht club is largely undocumented.

As a consistent yacht club member, Shōko joins the Odette II's practice cruise. She reports on mess hall refrigeration functionality during pre-flight checks. Stationed on the bridge, she operates console systems and assists with radar adjustments, methodically handling radar jamming, system reboots, and threat tracking during the Lightning 11 stealth ship's electronic attack. She later identifies the arrivals of the Bentenmaru and Barbaroosa.

Shōko is present when Princess Gruier joins the club during the Golden Ghost Ship arc, remaining involved in planning practice cruises under third-year supervision. In the Hakuoh Pirates arc, she assists in supervising first-year simulator trainees. She participates in commandeering the Bentenmaru while its crew is quarantined, operating the radar console during launch and the faster-than-light jump evading military vessels. She later joins the Princess Apricot raid in the police costume, aiding Jenny Dolittle's rescue from the Hugh and Dolittle fleet.

During the anime-exclusive Nebula Cup arc, Shōko assists in cleaning the Odette II at the relay station and delivers Marika Kato's lost ring to the Bentenmaru. She competes in the club's Nebula Cup qualifying race but does not advance. In the Pirate Hunter arc, she supervises dinghy simulations and witnesses the aftermath of the pirate battle with the Grand Cross. She returns to the Sea of the Morning Star aboard the Parabellum, greeting Chiaki Kurihara at New Okuhama Airport.

Following graduation, Shōko appears during the yacht club's spring recruitment preparations in "Abyss of Hyperspace." She participates in an operation spreading disinformation to mislead the Yggdrasil Group while Marika and Kanata pursue their mission. The group later discovers a tracking device planted on the club mascot, Odette-kun, during this operation.
