OVA
Description
Runa Suruga, nicknamed Runa-chan, works as a stoker in the engineering department of the destroyer Harekaze. She stands 152 cm tall and wears her long hair in pigtails secured by orange ribbons. Her personality is airheaded, scatterbrained, and excitable, making her the most forgetful member of her close-knit friend group. Despite this, she maintains a cheerful and kind nature, though occasional insecurities surface when she compares herself to others.
Born on December 14 in Hayama Town, Miura District, Kanagawa Prefecture, she is a Sagittarius with AB blood type. Her father, a ship designer, inspired her early fascination with machinery; as a child, she diligently copied his blueprints into personal notebooks. Academically, she excels in physics—especially mechanical structures and thermodynamics—but struggles with Japanese. She holds certifications as a Junior Third-Class Marine Engineer (Mechanic), First-Class Junior Boiler Technician, and Standard Boiler Welder.
Within the engineering team, she communicates non-verbally with chief engineer Maron Yanagiwara during repairs, often using tools like spanners to convey technical information. Her technical aptitude shines in projects like constructing a tandoor oven from a boiler for Megumi Uda, though the project remains unfinished, contrasting her otherwise clumsy persona.
She forms a quartet with Reo Wakasa, Sakura Ise, and Sora Hirota, frequently sharing gossip and playing games like cat's cradle, marbles, and mahjong. Despite her enthusiasm for mahjong, she constantly forgets rules and makes mistakes during games, prompting lighthearted exasperation from her friends—a recurring dynamic humorously depicted in the OVA.
A notable incident occurred when she reacted to her academic results: failing to see her name on Yokosuka Girls' Marine High School's primary acceptance list (she was admitted as a backup), she impulsively jumped into the winter sea, requiring rescue by Satoko Katsuta.
Her preferences include favorite foods like okonomiyaki and sweet red bean jelly, while she dislikes nameko mushrooms. She often uses the phrase "spring, summer, autumn, winter" and identifies yellow as her favorite color. Combined with her friends' preferred colors, their group can theoretically create any color.
