OVA
Description
Erwin, legally named Riko Matsumoto, is a second-year Ooarai Girls High School student. She commands and operates the radio for the Hippo Team's German Sturmgeschütz III assault gun. A member of the school's history buffs club, she possesses deep expertise in European history, especially World War II. Her appearance features short blonde hair styled with spiked sides evoking fennec fox ears, brown eyes, and distinctive attire: a German Field Marshal's cap inspired by Erwin Rommel, tall German Marschstiefel boots, and an Afrika Korps General's jacket layered over her school uniform, with her neckerchief tied in a bow. She wears the standard Ooarai sensha-dō uniform during tankery matches.
Her personality projects confidence and decisiveness, often marked by an almost cocky smile, traits mirroring her historical namesake. She maintains composure except under extreme pressure. Within the Hippo Team, she shares command responsibilities with Caesar, sometimes absent from strategy meetings. Her historical knowledge fuels passionate defenses of military equipment, like her argument for the StuG III's effectiveness during the Winter War.
Her name carries specific meanings: "Riko" combines Japanese characters for "village" and "child," while "Matsumoto" signifies "pine tree" and "origin." Her chosen alias "Erwin" translates to "respected friend" in German. Notable trivia includes her favorite flower, the cornflower, and her preferred tank, the Jagdpanther. Her birthday falls on June 18th, coinciding with Winston Churchill's "Finest Hour" speech and Charles de Gaulle's Appeal of 18 June in 1940.
In the OVA "This Is the Real Anzio Battle!," Erwin participates in the match against Anzio High School. Her team engages Anchovy's P40 tank and encounters a Semovente commanded by Carpaccio. The Hippo Team coordinates with other Ooarai units during the battle, contributing to the victory by cornering Anzio's forces. Her role remains consistent with her established expertise and command style.
