Contrary to her elegance and beauty, Jennu is strong, brave, and often more macho in behavior than some of the boys in her class. She is mature for her age, acting as a guardian for her classmates and trying to look out for everyone. She is especially respectful towards other girls. Jennu is a big fan of the Hosekizuka Troupe (宝石塚歌劇団), an in-universe equivalent to Takarazuka Revue, an all-female musical theatre troupe. Her dream is to one day become a member of the troupe.
