Paku is portrayed as fairly soft-spoken, considerate, and possesses a benevolent nature. Even as a child, she has shown prominent signs of her kindness by befriending Kamiki despite what others might think of her. She does not seem to be at all confident in her capabilities as an Exorcist, which is why she admires Kamiki for being such a skilled and talented student. Paku has a strong sense of justice when it comes to friendship and was disappointed when Kamiki was making a fool out of Shiemi, as she only wanted to be their friend.
