Ouka Sayama

Ouka Sayama is a Manyu assassin and Muneyuki's bodyguard, sent to pursue Chifusa. Cold and merciless in combat, she is an exceptionally skilled swordswoman whose ability is described as matching, and possibly surpassing, Chifusa's. Her past with Chifusa began with a duel when they were both young, and Muneyuki later employs her despite her low social standing. Her feelings for Muneyuki are implied to stem from that kindness.
