Mika's parents died in the Embassy Occupation Incident six years ago. He was then taken in by relatives and enrolled in officer school as a scholarship student. He graduated at the head of his class and proceeded to join the S.S.S. (the Special Space Service under the Arria Federal Army). He is currently the new leader of the S.S.S. 3rd Squad.
He's not very aggressive by nature, and still feels uneasy with his title of "squad leader." However, he has long desired to learn the truth of his parents' death, and isn't above taking action that would otherwise be unusal for him in order to learn more.
