Akashi, a Repair Ship of the Sakura Empire's Akashi-class, possesses distinct feline traits including long green hair secured by a large brown ribbon, cat ears, and yellow cat-like eyes. A bolt-shaped hairpin adorns her right bangs. She wears a white sailor-style dress with a brown collar, yellow gear-themed accents, and oversized sleeves featuring yellow cuffs with paw-like designs. Her attire is completed by asymmetrical white socks, brown shoes, and a red ribbon with a bell around her neck.
She exhibits playful, affectionate feline mannerisms, frequently using the verbal tic "nya". Akashi displays a strong fondness for gifting items, though her choices often lack practicality.
