Hamura Shou, the older fraternal twin brother of Kai Misonou, physically appears younger than his sibling. Separated from Kai during childhood after their biological parents—royalty of the white-winged Winfield Kingdom—perished protecting them, Shou endured time in an orphanage. Adopted at age five by a wealthy family, he faced further loss when his adoptive parents died in an accident, forging his resilient and optimistic nature.

He transfers to Yuusei Academy as a sports scholarship student, having secured a national kendo championship. Academically challenged but athletically gifted, he leads the kendo club. His enrollment stems from his conviction that fellow student Kai is his long-lost twin, though Kai initially denies any relation due to repressed childhood trauma.

Shou sports short, spiky blonde hair, green eyes, and stands approximately 166 cm tall. At the academy, supernatural events unfold, including an earthquake that transports him and others to another world. There, a monster attack triggers the emergence of his white wings, unveiling his heritage as a Winfield Kingdom prince.

Energetic, courageous, and fiercely just, Shou protects friends like Anri Chikura from bullying. His bond with Naoto Aoki grows complicated when Naoto is revealed as a black-winged individual, placing them on opposing sides of the white-winged and black-winged clan conflict. Through his journey, Shou hones leadership skills and combat prowess, blending kendo techniques with wing-based powers. His relationship with Kai evolves from rejection to a protective bond, especially when Kai faces emotional or physical threats. Gradually, Shou embraces his royal destiny and responsibilities in the Winfield Kingdom's struggle.
