Yatora Yaguchi's cram school classmate, Maki Kuwana, specializes in oil painting. Despite appearing lively, energetic, and slightly eccentric, Maki struggles with feelings of inferiority towards her older sister. This leads to low self-esteem, difficulty recognizing the impact of her artistic contributions on others, including her sister. Furthermore, Maki is very kind and considerate. She generously shares her food with those around her and expresses concern for their wellbeing.
