Maron Yanagiwara

Height: 146 cm (4'8")

She is a childhood friend of Hiromi Kuroki and hails from the same hometown. Although she is a dependent type who fears being alone, she puts on a cheerful front for those around her.

Despite being from Choshi City, Chiba Prefecture, she possesses the spirited, straightforward attitude of a true-blue Edokko (native of old Tokyo). Influenced by her grandfather—a fan of period dramas—she grew up watching the genre with him and developed a fondness for the distinctive Edo-style dialect.

She is skilled at tinkering with machinery; as the crew member in charge of the engines, she takes such pride in her role that she refers to herself as a "stoker" (or "boiler-tender"). Having studied marine engineering since junior high school, she possesses top-tier technical skills and an exceptional memory—capable of recalling blueprints after seeing them just once. However, her somewhat careless nature can be a drawback. With the mindset of a dedicated artisan, she often stays behind in the engine room to tend to the machinery or take a quick nap, even when the rest of the crew is relaxing or playing on the deck.

She also met the other members of her close-knit quartet of Engineering Department friends during the entrance exam.

Since her grandfather was a fisherman, her family meals consisted of fish dishes day after day; consequently, while she became skilled at dressing fish, she grew to dislike eating them.
