Sabine

Sabine is the third princess of the Zegreius Kingdom, whose bond with the female protagonist Koharu was forged after Koharu rescued her from a kidnapping crisis. She holds a deep admiration for Koharu and affectionately calls her "big sister." Behind her innocent and endearing appearance lies a sharp intellect and a remarkable capacity for learning — she picks up Earth's language, games, and shooting skills with striking speed. She frequently sneaks away from the palace without her guards' knowledge to visit Koharu's general store, where she delights in modern snacks and contemporary culture.
