Karasuki Homura

Summary
He is the current king of the Karasuki kingdom as well as Ayame's father and Rio's grandfather. In the past he realized Zen's and Ayame's feelings for each other and even though he wished to let them get married he wasn't able to because the nobles from other faction's wouldn't have accepted a marriage between a princess like Ayame, despite her post in the succession list being low, and an upstart like Zen, despite him being a famous war hero. After the ceasefire incident he ordered Zen and Ayame to escape together while pretending to accept the demands from the Rokuren kingdom's prince of turning them over. With the time that he gained with his charade he made preparations for winning the war against the Rokuren kingdom.

Homura's plans succeeded but in exchange Zen and Ayame lost their place in the Yagumo region due to his scheme, which was something that has always weighed on his mind until Rio told him that his parents were happy together and that he never saw something like regret or sadness in Ayame's face.

After hearing of Rio's plans of avenging his parents he was prepared to stop him if he considered that Rio didn't have what was necessary for going down that path. Deeming Rio sane and smart enough not to do something insane for the sake of avenging his parents he chose not to stop him and instead decided to lend him a hand.

He ordered Gouki to have a mock battle with Rio, with the expectation that Rio would be defeated by him in order to afterwards convince him to live in Gouki's home as his disciple and stay there until he gained enough strength for his purpose. This was also a plan that was supposed to give him an easier way of meeting with Rio more often, although against everyone's expectations Gouki wasn't able of putting a scratch on Rio, and his plan failed.

In future reunions with Rio he offered to have Gouki, Kayoko, Komomo and a group of ten Anbu join Rio in his journey for revenge but Rio refused.
