Busujima, Riou Mason

Half-American on his father's side, and half-Japanese on his mother's. He speaks and behaves as if he were still a soldier. During his time as a naval officer, he respected rank above anything else. For example, if a superior told him that white was black, then white was black. In dire circumstances, he shows no mercy to his enemies.

That being said, he's more calm in peacetime, and likes to help people. His hobby is cooking food that serves a practical purpose. His skills are those of a professional, but for some reason, Samatoki Aohitsugi and Jyuto Iruma fear him.
