Jimochi

A former "Honorary Knight" who serves as a butler in the kingdom. Currently, he only appears in flashback scenes. At first glance, he seems strict, but he has a worldly side, secretly buying snacks for the princess after her practice, and stopping by family restaurants (in fact, these aspects are highlighted in the story, and Ex often points them out). He is a master who taught the princess the sword techniques that became her special moves, saying that if she could learn the technique in a week, she could spend the rest of the given month playing (the princess learned it in 5 days and spent the remaining 25 days playing), skillfully managing the princess and significantly influencing her personality, for better or worse.
