Natsuka

He is the eldest son of Natsumihiko and the half-brother of Wakamiya. His mother, Yuzemi, is the lawful wife. Intelligent and possessing the dignity befitting an elder son, he was considered the most promising candidate for imperial succession. However, when his grandfather, the previous Kinu and Haku, recognized Wakamiya as the "true Kinu," he chose to become a monk and assumed the position of head of Myoukyouin. Although he appears to be in conflict with his younger brother on the surface, their sibling relationship is actually harmonious.
