三宮 三葉

Mitsuba is a special duty second lieutenant of the Japanese Imperial Demon Army and a member of Shinoa Squad. She has been a member of the annihilation force ever since she was 13. Mitsuba is shown to be a serious and by-the-book soldier, who dislikes those who break the formation and commit to individual action. She tends to have a fiery personality and may be the most talkative of the group. In her previous squad, she once broke the formation of her team in order to save a teammate, which lead to her squad's annihilation. This makes her value staying in formation and following the rules, which she enforces on the rookie soldiers below her. She is proud and hates being promoted for doing nothing just because of her family name. She considers that to be a grave insult. She also felt insulted when assigned to work under Shinoa, but she quickly takes her place as second-in-command. [From Wikipedia, Owari no Seraph Wiki]
