Kiyomizu operates within the Jaki, an elite ninja unit called Night Chasers focused on covert movement and intelligence gathering. Her core duties involve coordinating rebel activities and surveilling palace developments through the Jaki network. She often positions herself near the capital to streamline communications with Fujina, who operates deep in enemy territory. For swift information relay, Kiyomizu and fellow Jaki agents utilize mirrored light signals across outposts. She vigilantly monitors and safeguards key allies—General Iga, Imari, Masahiko Kutani, and Himiko—stepping in during threats. When unveiling herself, her identity as a young woman consistently startrays those she rescues. Beyond espionage, she commands extensive military tactics knowledge. Once emerging from concealment, she exhibits a distinctly friendly demeanor. Her appearance features dark blue hair styled with ribbons in a ponytail, blue eyes, and a choker accessory. She allies with the Yamatai faction.
