Waltrud Krupinski

Waltrud Krupinski is a veteran ace of the 502nd Joint Fighter Wing, originating from Karlsland and attached with the Karsland Air Force. She is referred to as Earl and Countess to her friends. (Source: strikewitches.wikia.com) She also tends to approach other witches romantically and calls her cute comrades "koneko-chan tachi" in an elegant tone which could make you lose your mind either from its lasciviousness or creepiness.
