安蒂尔

“She has no intention at all of getting along with us, does she…” The protagonist. He enrolled at Libra Lapis Lazuli Private Academy as a first-year student after receiving a mysterious prospectus in the mail. On his first day of school, he gets caught up in a certain incident and accidentally breaks a bronze statue in the courtyard. The principal decides to assign him to the Bureau for the Investigation of Special Affairs as compensation. He has an aggressive personality and a somewhat rude tone of voice, but on the inside he’s a very caring person, which leads to him getting caught up in all sorts of trouble. He also has a pretty sharp mind, but he gets frustrated when he can’t keep up with Ushio’s quick reasoning. Ushio is like a rival to him, and he often picks fights with her. He dislikes being called “Michiru,” possibly because he doesn’t like his name. [From the English official site.] His real name is Koga Mitsuyoshi (久我 三厳), the 20-year-old brother of Koga Michiru.
