Excel's junior officer, with a penchant for dying and reviving in quick succession.
She is noticeably Il Palazzo's favorite officer, usually receiving lighter punishment and higher promotions than Excel. Hyatt is a rather innocent, naive and sensible woman, often serving as the agent that thinks things through more as opposed to Excel who seems to act on impulse. She is an expert sniper.
Although she is rather oblivious to Il Palazzo's mild romantic interest in her, she is well aware of the more rampant romantic intent of their neighbour, Watanabe, who knows her by her alias of "Miss Ayasugi." Il Palazzo's romantic interest in Hyatt only appears in the anime.
She is a failed, artificially made human created by Dr. Tenmangu. She was designed to resemble Tenmangu’s wife, Miwa. Given that the real Miwa died of a serious illness, Hyatt’s condition may stem precisely from her connection to Miwa. Throughout the story, Dr. Tenmangu feels a certain, understandable attachment toward her.
