Misaki Miyashita is a timid junior high sophomore student who isolated herself, believing friendships inevitably lead to mutual hatred, influenced by her parents' troubled relationship. Her primary hobby is drawing, and she frequently uses otaku terminology. Her dark brown hair falls to her shoulders, and she has purple eyes.

She becomes the owner of Budoko, a petite yet fiery aluminum akikan originating from a grape juice can who speaks distinctively. Budoko serves as the catalyst for Misaki's transformation. Their deepening bond, sharing quiet moments like stargazing and including a kiss, helps Misaki gradually overcome her fear of relationships.

She appears in the main "Akikan!" anime series and its OVA, "Akikan!: Kan Ippatsu!? Onsen Panic," with consistent portrayal. Her story concludes showing growth through her connection with Budoko, emerging from isolation. No additional canonical developments occur in other media; her background, personality, and interactions remain consistent across verified sources.
