Shizuka Tsuruki is the leading main character from the Girls und Panzer spinoff, Girls und Panzer: Ribbon no Musha.
Shizuka, Matsukaze Rin, and Endou Haruka are students at Tatenashi High School. They represent the school in Tankathlon (a cousin of Tankery) under the banner of Team Centipede. Shizuka is not only the team's leader, but also serves as the commander, gunner, and loader of the team's sole vehicle, a red Type 97 Te-Ke tankette.
She has upward-angled red eyes and short brown hair (or black, depending on the artist). Her long bangs have been swept around in an unusual loop and kept in place with a large red ribbon tied into a bow, from which the series derives its name. She also has a mole under her left eye. Shizuka is most often found wearing either a white dress shirt or the full Tatenashi High School uniform, along with loafers and brown pantyhose. However, she frequently slips off one of her shoes in battle in order to non-verbally convey her directions to Rin.
On more than one occasion, she has gone into Tankathlon battles wearing a suit of classical Japanese armor and wielding a bow.
Shizuka makes frequent use of the emblem of Takeda Shingen's Centipede force, even to the point of making it her own team's emblem and decorating the Type 97 with the symbol.
