Ishista, known also as Ishtar, reigns as the supreme deity, exuding maternal authority and grandmotherly wisdom. Her elderly visage, marked by grey hair and calm composure, reflects an unwavering patience toward discourtesy. Tasked with upholding cosmic balance, she mentors younger gods such as Ristarte, devises strategies against existential threats like Deathmagla’s armies, and governs the divine Order—a system empowering deities to harness their full might. Though her combat skills remain undefined, her immortality and strategic mastery cement her role as a linchpin in resolving interworld disputes and enforcing celestial laws.

Her foresight and deep wisdom enable precise predictions of future events, guiding her counsel. She oversees Ristarte’s celestial journey, disclosing the goddess’s mortal past as Princess Tiana of Ixphoria, whose love for the hero Seiya ended in sacrificial death and rebirth as a deity. Ishista intertwines Ristarte’s fate with Seiya’s ongoing mission, bridging lifetimes and worlds.

Balancing rigidity with compassion, she bends divine statutes when necessity demands, such as authorizing Ristarte’s forbidden re-summoning of Seiya to save Ixphoria. Though she enforces consequences for transgressions—like stripping Ristarte’s powers for Order misuse—she offers paths to redemption through arduous trials. As both mediator and enforcer, she navigates rule-breaking and crises with equal resolve, ensuring multiversal stability while acknowledging the emotional weight carried by those under her watch. Her leadership merges unyielding authority with undercurrents of empathy, solidifying her as the cornerstone of celestial order.
