The current ruler of Karasuki is Zen's father and Ayame's grandfather. In the past, he recognized the romantic feelings between Ayame and Zen, but due to opposition from nobles in other factions who deemed a marriage between a low-ranking princess like Ayame and a renowned war hero like Zen unsuitable, he was unable to allow them to marry. Following the ceasefire incident, he ordered Zen and Ayame to flee together while pretending to comply with the demand of the Rokuren kingdom's prince to surrender them. During this time, he made preparations for a successful war against the Rokuren kingdom.
