Kiyomi Azumabito is the ambassador from Hizuru, representing the nation's leading Azumabito family which shares ancestral ties with the Eldian royal family. A middle-aged woman of average height, she has small facial features, thin eyebrows, and black hair typically secured in a neat bun. At diplomatic functions, she wears traditional Hizuru kimonos. She exhibits a pragmatic, financially driven personality, displaying keen interest in Paradis Island's resources, especially iceburst stone—a mineral powering advanced technology like vertical maneuvering equipment. Her desire to exploit this resource for Hizuru's economic benefit manifests visibly, such as drooling when discussing potential wealth. Despite this opportunism, she maintains calm and secrecy in high-stakes situations: she concealed Udo's accidental wine spill on her kimono to protect him and subtly acknowledged Willy Tybur's impending fate without revealing her knowledge. Her involvement with Paradis begins when Zeke Yeager proposes Hizuru gains access to the island's resources in exchange for technological modernization. Kiyomi agrees, viewing it as a path to restore Hizuru's power. During her first visit to Paradis around 852, she identifies Mikasa Ackerman as a descendant of the Hizuru shogunate's royal line through a son of the shogun who stayed with King Fritz. Kiyomi expresses reverence for Mikasa's lineage, privately vowing to protect her based on familial pride over political or financial motives. She outlines a 50-year plan for Paradis's technological advancement to military leaders. This strategy relies on Historia Reiss inheriting Zeke's Beast Titan and bearing multiple royal-blooded children to maintain the Founding Titan's power, deterring global aggression while Paradis catches up. She later attends events in Liberio, including a pre-festival party where her interaction with Udo occurs, and Willy Tybur's stage production, which she avoids. After Eren Yeager initiates the Rumbling, Kiyomi travels to Paradis on a flying boat powered by iceburst stone. During military upheaval, Floch Forster and the Yeagerists capture her and her engineers at the harbor, executing some to coerce cooperation. Kiyomi remains composed, disarming Floch during a confrontation and highlighting the futility of internal conflict amid global destruction. Rescued by Mikasa and others, she advises relocating the flying boat to Odiha for efficient repairs, enabling the alliance's pursuit of Eren. En route from Odiha, Kiyomi confides in Annie Leonhart, expressing regret for enabling the Rumbling and acknowledging Hizuru's likely destruction. When Falco Grice proposes testing his Jaw Titan's flight capability—risking the ship—she accepts the potential outcome, facilitating an evacuation to lifeboats. By 857, she participates in post-Rumbling peace talks on Paradis alongside Queen Historia. Kiyomi possesses unexpected martial skill, demonstrated when she subdues Floch. Her relationship with Mikasa remains a consistent priority, driven by clan loyalty. She shares a birthday with Annie Leonhart.
