Kouha Kannei

In the anime, she is a loyal bodyguard and warrior to the Son family. While normally calm, she becomes hotheaded when someone questions her loyalty to the Son's. In the visual novel, she is a loyal ally of Sonken's who almost never leaves her side. She feels thankful for Kazuto as he has made Sonken more happy and lighthearted compared to when Sonken was still a ruler. (Source: Wikipedia)
