Ouka Sayama

Ouka Sayama is a Manyu assassin and Muneyuki’s personal bodyguard. She hunts Chifusa with a skill level that rivals or exceeds her target's. Their rivalry is rooted in a childhood duel where Chifusa accidentally used the Breast Flow technique on her, an event that forced Ouka to live as a commoner. After this loss, she found refuge under Muneyuki’s protection and developed a deep, unspoken affection for him.
