OVA
Description
Junko Heki, nicknamed "Jun-chan," is a main gunner aboard the destroyer Harekaze. She operates the ship's main battery alongside Hikari Ogasawara and Michiru Takeda. Junko sports light brown hair, usually tied in a bun with parted bangs, and wears the standard Yokosuka Girls' Marine High School uniform. Her petite 153 cm frame contrasts with her vibrant energy.

Born February 5th in Tsu City, Mie Prefecture, her family name "Heki" (written with the characters for "sun" and "setting") proved difficult for others, leading to early isolation. This changed when Hikari, Michiru, and especially Akeno Misaki learned her name, fostering Junko's deep loyalty. Her blood type B reflects an adaptable yet sometimes impulsive nature.

Academically, she excels in physics, mathematics, earth science, and meteorology, applying this knowledge directly to artillery duties like calculating trajectories. She holds a Class-A Powder Handling Safety Manager license. However, chemistry remains a challenge. To hone her aiming precision and grasp of projectile motion, she practices ring toss games. She often peppers her speech with playful onomatopoeia like "Bang!" and enjoys crafting elaborate fictional scenarios about her crewmates.

Her closest bonds are with fellow gunners Hikari and Michiru, forged through shared duty and their early acceptance. Junko highly values camaraderie and responds warmly to those who recognize her. She favors deer meat and the color light green, while disliking broccoli.
