She is a bit prone to jealousy.

Glycine Bleumer (16 years old). The daughter of the Bleumer family, inheriting the blood of the noble House of Normandy. Contrary to her elegant appearance and natural nobility, the Viking blood flowing within her makes her brave but prideful. Due to her belief that people should live with pride and her upbringing as a natural-born aristocrat, she tends to keep commoners and foreigners at a distance. She has gradually opened her heart to Guest and developed secret feelings of love. She addresses Guest as "Sir." She excels at handling battle axes.

The daughter of the Japanese Baronial House of Kitaoji. Since her grandmother is French and she has lived abroad since childhood, she does not know Japan well. However, she excels in Japanese arts such as calligraphy, flower arrangement, and archery, and enjoys reading. Currently, she is staying with the Bleumer family, with whom she has a long-standing relationship, as a Japanese exchange student. She is a "Yamato Nadeshiko"—graceful, quiet, always smiling, and absolutely obedient to a gentleman's word. However, she lost a former partner named Philippe in a tragic accident, and due to that experience, she has become somewhat obsessed with Guest.
