Tenmoku holds the position of one of the Great Four Lords governing the Kune Kingdom, appointed by Governor-General Shikara to administer provinces within the occupied territory of Yamatai. She projects a distinctly less martial presence than her fellow lords, favoring opulent attire that reflects her expertise in courtly politics and intrigue. Her sharp tongue and deep knowledge of political maneuvering within the Kune leadership lead her to deliver frequent, biting commentary—directed without reservation even at Shikara himself. Despite this outward focus on courtly affairs, she possesses unexpected proficiency in swordsmanship. Her responsibilities involve governing an assigned region under Kune's control, operating within the military hierarchy established by Shikara during the invasion and occupation of Yamatai.
