Mikihito Higashida is a supporting character in the light novel and anime series Kämpfer. He is a second-year student in the Boys' Department of Seitetsu Academy and serves as a classmate and close friend of the male protagonist, Natsuru Senou. Physically, he is depicted as a teenage boy with short orange hair and green eyes.

Higashida is best known within the story as the president of the school's bishoujo research club, an interest that defines much of his on-screen personality. His primary motivation revolves around his fascination with attractive girls, and he frequently tries to recruit new subjects for the club's admiration. This leads to one of his key narrative functions: his interactions with Natsuru's female Kämpfer alter ego. Higashida remains completely oblivious to the fact that the female form he encounters is actually his male friend transformed; instead, he mistakes her for a distinct individual and fixates on recruiting her as a new member of the club. This obliviousness provides a recurring source of comedic situations and highlights his single-minded focus on his hobby.

His role in the story is that of a supportive friend within the everyday school setting. He provides a sense of normalcy and comic relief amid the supernatural conflicts involving the Kämpfer. His relationship with Natsuru is that of a typical friendly classmate, but he has no knowledge of or involvement in the Kämpfer battles. He does not possess any special abilities and remains a completely ordinary human throughout the series. His development is minimal, as he largely serves as a static background character whose primary purpose is to react to events he does not fully understand.
