Shis holds the position of First Princess of Kujyuri, eldest daughter of Ozen and sister to Yashmah and Rulutieh. Initially absent due to a political marriage, she abruptly returns upon learning of Rulutieh's arrival. An attractive woman typically seen in red attire, Shis possesses a strong will and deep sense of duty, especially toward her youngest sister. Following their mother's death during Rulutieh's birth, Shis adopted a surrogate maternal role, leading to intense overprotectiveness. She forbids Rulutieh's participation in the war, haunted by her mother's fate, and physically restrains Rulutieh from leaving with allies, dismissing their comrades as unfit guardians. She demands anyone protecting Rulutieh must surpass her own combat skill. Shis admires powerful warriors, particularly those who defeat her. This trait proves pivotal after her duel with Oshtor (Haku impersonating the deceased general). Oshtor's victory—marking her first defeat by a man—catalyzes a significant shift. Conceding to his strength, she formally acknowledges the alliance between Kujyuri and Ennakamuy. Crucially, she entrusts Rulutieh's protection to Oshtor, signifying acceptance of her sister's autonomy and resolve. The defeat also sparks romantic feelings for Oshtor. Visibly blushing, she presents him with a gift, requests his continued guardianship of Rulutieh, and vows future support at his side. Her overt affections provoke jealousy among observing female characters. Yashmah suggests restraint, but Shis reacts with physical admonishment, demonstrating her persistent assertiveness. During the alliance celebration, Shis reconciles with Rulutieh's independence. She gifts their deceased mother's flute as a memento, affirming Rulutieh's emotional resilience and pledging enduring family solidarity. This act symbolizes her transition from coercive protection to supportive affirmation. Her family dynamics are consistent: she shares a conventional, though dominance-driven, sibling bond with Yashmah, compelling his compliance. Her relationship with Rulutieh defines her core motivations, evolving from stifling concern to respectful trust. Regarding Oshtor, her attitude shifts from dismissive hostility—rooted in his support for Rulutieh's battlefield role—to profound admiration and affection after his combat victory and unwavering resolve.
