OVA
Description
Noriko Isobe commands and loads the Type 89B medium tank for Ooarai Girls Academy's Duck Team. A second-year student from Ooarai, Ibaraki, she previously captained the school's defunct volleyball team as its setter. Her pursuit of sensha-do stems from a conviction that tankery success could enable the volleyball program's revival, though the precise connection remains unclear. Despite being a year senior to her crewmates, she is the shortest member, recognizable by her short dark brown hair, dark brown eyes, and habitual spats-and-T-shirt attire instead of the standard volleyball uniform.

Noriko embodies determination and willpower, epitomizing her "GUTS!" motto with a hot-blooded, sometimes stubborn belief that courage and effort conquer all obstacles. She demonstrates strong battlefield leadership, maintaining calm under pressure and issuing clear tactical commands. This contributes to Duck Team's high evasion and hit rates within Ooarai's forces. Though occasionally depicted with "dumb jock" traits like misunderstandings or physical comedy, she possesses genuine tactical awareness—effectively directing her crew during Anzio ambushes or sudden enemy flag tank encounters. Her volleyball background deeply influences her tankery: she adapts serving techniques for precise smoke flare launches and suffers volleyball withdrawal, comically manifesting as seeing volleyballs everywhere and reflexively groping more endowed teammates.

During the Anzio battle, Noriko led reconnaissance at the central crossroads. She identified discrepancies in reported enemy tank numbers, exposing "Operation Macaroni"—Anzio's cardboard decoy ruse masking an encirclement. Engaging Anzio's Carro Veloce tankettes commanded by Pepperoni, she realized their Type 89B shells merely tipped over the lightweight vehicles. Standing exposed in the hatch for "heads-up" targeting, she directed precise shots against weak points, immobilizing four tankettes. This forced Anzio to abandon its encirclement and regroup, showcasing Duck Team's evolution into an agile reconnaissance and harassment unit.

Additional notes: Noriko has an older brother. Her physical and thematic resemblance echoes real-world volleyball champion Sata Isobe (1964 Tokyo Olympics). Her birthday historically coincides with the issuance of Stalin's Order No. 227. She earned nicknames like "Duck-dono" and "Small Duck" from Chi-Ha-Tan Academy's Fukuda after joint matches. Spin-off media depicts her actively countering perceptions of her team as "muscle-headed" through academic efforts, though her athletic prowess is unquestioned. Her commitment extends to wearing her volleyball uniform beneath mandated attire during Public Morals Committee enforcements.
