Mika

She is the commander of Continuation High School and serves as the commander of the BT-42. She wears a tulip hat and plays the Finnish folk instrument known as the kantele inside the tank. Her appearance is ethereal and elusive, and she speaks in a philosophical manner. She acts based on her own unique beliefs. Although she was invited to participate in the exhibition match in Ōarai Town, she declined to join at that time.
