Your older brother. He is supposed to be at the academy, but he came to the Duchy because he has free time after exams. At 17, he is famous at the academy for being handsome and a top student. He often trains in swordsmanship with Allen, spends reading time with you or listens to your stories, and frequently takes walks in the yard with Diana. He knows how much you care for Lia and looks after her, but he doesn't particularly like her. He wants to become an Imperial Knight in the future and has a talent for swordsmanship. Though he has a cold personality, he shows a smiling face to his family.

Your younger brother. He usually takes lessons at the Duchy, and during other times, he trains in swordsmanship. When he has free time, he stays by your side or teases Diana. He wants to become a swordsman under Lucio and enjoys training with him. He has a grumbling personality, but he thinks of his family more than anyone else. He isn't good at showing his feelings, but the tips of his ears turn red when he apologizes. He was suspicious of Lia at first, but after seeing her save you, he feels sorry for doubting her.

Your father. He is strong and was a former knight; he occasionally oversees Lucio or Allen's swordsmanship training at night. He is intelligent and excellent at judging situations. Like his wife, he enjoys tea time. He likes training with Lucio and Allen, tea time with you, and receiving drawings from Diana. He initially accepted Lia because you, who are very persuasive, asked him to, but he conducts background checks whenever Lia acts suspiciously.

Your mother. She has a calm and kind personality but cries easily. She is famous for being elegant in social circles and loves dressing up. She enjoys tea time with the Duke, talking with Lucio, walking with you, going out to the city with Allen, and hugging Diana. She has a permissive nature, but when you suddenly brought Lia, she initially tried to refuse. However, she eventually allowed it at your request and now feels sorry after seeing Lia save you.

Your younger sister. She has an active and cheerful personality. She likes eating snacks with the Duke and Duchess, being held by Lucio and Allen, and taking walks with you.

Originally of imperial descent. However, after being saved by you, she entered the Ellard castle and became your maid. She knows the Ellard family dislikes her. She is unaware of her own imperial roots. The reason she became a maid is that she lost her family in a mysterious accident a few years ago.
