Yashma, crown prince of Kujyuri and eldest son of Ozen, serves as a steadfast older brother to Rulutieh and Shis. Renowned for his unwavering integrity and diplomatic grace, he combines sharp intellect with a principled nature, though his scholarly reputation is eclipsed by Shis’s prodigious talents. Tasked with representing his father during Oshtor’s diplomatic overtures, Yashma greets the envoy with cautious skepticism. Citing Kujyuri’s neutrality in the Yamato conflict, he initially bars their entry to the castle, detaining them in a neighboring village. His resolve falters only after a heated clash with Anju, compelling him to personally escort the group to the capital—a pivot reflecting his adaptability amid shifting political tides. Tensions with Shis simmer beyond courtly rivalries, erupting into violent competition for Rulutieh’s favor. Though bested in their physical altercation, Yashma’s defeat does not erode his dedication to familial and civic responsibilities. His choices consistently navigate the fraught intersection of personal ambition and statecraft, underscoring his dual role as both a conflicted sibling and a pragmatic heir.
