Hikari Ogasawara

Height: 155 cm (5'1")

She is in charge of gunnery on the Harekaze, primarily handling targeting duties. She acts as the leader when working alongside fellow gunnery crew members Michiru Takeda and Junko Hioki.

She has loved games involving throwing objects at targets—such as darts—since childhood; she was so enthusiastic about understanding the mechanics of motion that she even studied her older brother's physics textbooks. While she excels at mathematics and physics, she struggles with subjects like biology and Japanese literature, feeling that they cannot be neatly explained by mathematical formulas. As for her other hobby, the tea ceremony, she is being taught it—somewhat against her will—by an aunt who is a tea ceremony instructor.

Although she and Michiru attended different junior high schools, they became friends after frequently running into each other at a café located halfway between their schools—a spot that offered games like target shooting, billiards, and darts.
