Hyatt

Hyatt is Excel's frail junior officer, with a tendency to cough huge amounts of blood, drop dead and suddenly spring back to life in quick succession. In the original manga, Hyatt joins ACROSS by simply answering an advert placed by Il Palazzo; the anime, meanwhile, states that she is a mysterious princess from space (supposedly) with a connection to the Puuchuus and Space Butler. Her curious medical condition is never explained in detail, neither in the manga nor in the anime (although later volumes of the manga hint that Il Palazzo has implanted something in her body that is causing it—and it is implied in the anime that, as she is from Mars, Earth's atmosphere is bad for her lungs). In both the anime and the manga, she is noticeably Il Palazzo's favorite officer, usually receiving lighter punishment and higher promotions than Excel. Despite this, the two girls usually get along just fine, and Excel even calls her "Ha-chan".
