Anchovy, born Chiyomi Anzai, commands the Sensha-dō team at Anzio Girls High School. Her nickname, which comes from her surname, aligns with Anzio’s Italian motif. She stands 156 centimeters tall and has long pale green hair usually styled in twin ponytails secured with black ribbons. To move anonymously at school, she sometimes wears glasses and alters her hairstyle. In matches, she wears a distinctive Italian World War II–inspired military uniform, while her standard attire includes a white shirt, black skirt, tie, and a black mantle. Her birthday is September 23rd. Her personality varies across different portrayals: some emphasize a hot-blooded, prideful, and fiercely competitive nature, while others show her as determined, self-assured, courteous, and gracious in defeat. She rebuilt Anzio’s declining Sensha-dō club and leads a team that affectionately calls her “Duce” or “Big Sister.” Due to her school’s limited tank fleet, which includes Italian CV.33 tankettes, a P40 heavy tank, and a Semovente da 75/18, she relies heavily on ambushes, deception, and tactics such as using cardboard decoys. Her intricate plans sometimes falter under pressure or because of her team’s impulsive tendencies and preoccupation with food. Despite financial struggles and resource limitations, she champions Anzio’s spirit and tradition of hosting parties before and after matches. After losing to Ōarai, she concedes with dignity and later supports them against a university team, repurposing her tankettes for reconnaissance and unorthodox tactics like a three-pronged attack. She accepts responsibility for failures rather than blaming her crew, showing protectiveness toward her subordinates. She dislikes being called by her real name, has a younger brother, is not a strong swimmer, and can be susceptible to peer pressure. Her favorite tank is the P40, her favorite food is cheese pizza, and her favorite flower is the daisy.
