Misono belongs to the Star Clan, destined by birth to aid the Priestess of the Dragon God. He shares an intensely close bond with his younger twin sister, Yukari, and demonstrates a fiercely protective nature toward her. Though often demonstrating maturity beyond his years, he carries himself with a distinct haughtiness, especially toward those he deems of lower status. This attitude fuels his initial reluctance to support the newly summoned Priestess, Karin, prioritizing social hierarchy and tradition above immediate need. His skepticism starkly contrasts with Yukari's ready acceptance of Karin. When duty compels him to assist Karin, he provides practical support, such as supplying traditional robes to help her integrate into the historical setting. Yet, he openly criticizes her unconventional alterations to the garment, underscoring his strict adherence to established customs and propriety. His focus remains firmly fixed on his sister's well-being and the rigid fulfillment of his clan's duties, leading to minimal direct involvement in the central conflict beyond logistical aid. His role is defined by this protective instinct toward Yukari and his tradition-bound, reserved approach to the Priestess's mission.
