Sakon was the chief mechanic of the Daiku Maryu, overseeing the maintenance and repair of the ship and its complex mechanical systems. His advanced engineering expertise enabled him to manage the vessel's intricate operations and support technologies. During the Daiku Maryu's initial development phase, he collaborated with Professor Tsuwabuki and Captain Garis, establishing his foundational connection to the ship's creation and its core mission.

He maintained a strictly professional working relationship with the crew, concentrating on technical duties and mechanical problem-solving rather than combat operations. Sakon had no documented involvement in piloting mecha or frontline battles. His association with Professor Tsuwabuki positioned him as a narrative link to Daiya Tsuwabuki's search for his missing father, though direct interactions or substantive narrative development related to this connection were not elaborated upon. Sakon's operational presence centered exclusively on engineering functions, with no further elaboration on his personal history, family connections, motivations, or interpersonal dynamics beyond technical contexts.
