Movie
Description
San-Daime is the chief engineer of the pirate ship Bentenmaru, tasked with maintaining propulsion, mobility systems, and damage control during operations. He possesses green hair, blue eyes, and a small goatee, typically wearing brown goggles. His practical engineering attire usually consists of a blue shirt with red accents, a vest, and light brown trousers featuring multiple pockets.

Personally, San-Daime displays a consistently pessimistic and anxious nature, frequently voicing worry during dangerous situations like spatial anomalies, enemy attacks, or technical failures. Despite this tendency to panic, he remains dedicated to his duties and does not let his fears compromise his technical performance. Outside work, he collects and trades teddy bears, revealing a more lighthearted aspect.

His background is minimally detailed, though he joined the Bentenmaru crew after Ririka, the former captain's partner, departed to raise her daughter Marika. This makes him a relatively newer addition compared to long-standing members like Misa or Schnitzer.

Throughout the series, San-Daime's engineering expertise proves critical in high-stakes scenarios. During the Hakuoh Pirates arc, with the regular crew quarantined and the ship commandeered by amateur students, he vehemently objects to their handling of the Bentenmaru, citing concerns about fuel line impurities and reactor instability. He collaborates on creating an emergency manual for the students and experiences severe anxiety when they attempt an unguided FTL jump, fearing catastrophic engine failure. In the Golden Ghost Ship arc, he monitors ship systems amidst turbulent spatial phenomena and combat, often vocalizing fears about imminent dangers while ensuring the vessel's operational integrity.

For the film "Abyss of Hyperspace," which centers on subspace anomalies and a mission involving the legacy of explorer Professor Mugen, San-Daime's specific actions or development are not detailed in the available sources. The film's plot summaries and character listings focus primarily on protagonists Marika Kato, Chiaki Kurihara, and Kanata Mugen, without referencing San-Daime's participation. His role remains consistent with his established shipboard responsibilities, though no additional narrative or character evolution is documented for this installment or any spin-off media.
