Kay

Kay (ケイ, Kei) is the head commander of the wealthy Saunders Girls High School tankery club. She commands an M4 Sherman in battle. Like her fellow American-inspired classmates, Kay is boisterous and extroverted, but also believes strongly in fair play despite Saunders' reputation for underhanded tactics. She would continue to support Ooarai Girls High School after their first match together.
