Leah Kazuno

Kazuno Leah  is a member of Aqours's rival group, Saint Snow. She is one of Saint Snow's two members, the other being her older sister, Kazuno Sarah. Leah is a first-year student at an unspecified school.

Background
Physically, Leah appears to be extraordinarily adept at parkour or gymnastics, able to somersault over the members of Aqours with only a running start.

While singing, Leah performs the rap segments of SELF CONTROL!!.

Personality
Leah possesses a pronounced sense of competitiveness, apparent in her hostility towards the members of Aqours. Her competitive attitude leads to her subsequent disparagement of Aqours in the aftermath of the Tokyo idol event.

Outside of competition, Leah adopts a stoic front towards fellow school idols. She is generally silent in the conversations between Saint Snow and Aqours, leaving the duty of displaying hospitality to Sarah. However, Leah is quick to react to comments she perceives as inane. This has led to her going as far as to call out Takami Chika for being an idiot when she questioned Saint Snow's desire to win the Love Live!.

Much like her sister, Leah displays a high level of conviction for Saint Snow's cause. Even as she maintains her stoic facade, she fights back tears upon knowledge of Saint Snow's failure to enter the winning group for the Tokyo idol event.

Leah seems be extremely self-confident as well, performing a bold somersault over Aqours in their first meeting to assert her dominance over her competition. She flashes a smirk towards Aqours whenever she impresses them with her performances.
