柳木 詩夢

She is the protagonist's classmate and Kanon's older sister.

Her personality is the complete opposite of her younger sister's, and although she is earnest, she is sarcastic and has low self-esteem. Because she speaks her mind, her classmates tend to keep her at a distance.

Although she can be stubborn, she is also a good older sister who worries about her younger sister, despite her harsh words. Although she is wary of the protagonist when he suddenly shows up at the dorm, she evaluates his actions without any prejudice.
