Description
Leah Kazuno is a supporting character in Love Live! Sunshine!!. She is a first-year student at Seisen Girls' Academy in Hakodate, Hokkaido, where she co-founded the school idol duo Saint Snow alongside her older sister, Sarah Kazuno. Her personal image color is white.

Leah's background reveals a naturally shy and reserved person who struggled to connect with others. In her early school years, she kept a distance from classmates and felt uncomfortable in social settings. This changed during the events of the second season, when she realized that her peers were willing to accept her despite her quiet nature. Encouraged by this acceptance, she gained the confidence to boldly declare that she would form a new idol group with them, marking a significant turning point in her character.

Her personality is defined by a pronounced sense of competitiveness, which manifests as hostility towards Aqours, especially after the Tokyo idol event where Saint Snow failed to advance. She often maintains a stoic and silent demeanor in group interactions, letting Sarah handle social hospitality, but is quick to react sharply to comments she considers senseless—going so far as to call Aqours' leader Chika Takami an idiot for questioning Saint Snow's desire to win. Despite her harsh exterior, Leah possesses a deep care for her sister, openly stating that Sarah is better than Dia Kurosawa. She also shows high conviction for Saint Snow's cause, fighting back tears when facing failure.

Leah appears extremely self-confident in performance. She demonstrates remarkable physical agility, capable of performing a somersault over the members of Aqours with only a running start, and frequently smirks when she impresses others. As Saint Snow's rapper, she contributes a distinct vocal style to the group's hard rock and metal-influenced sound.

Her role in the story is primarily that of a rival to the main group Aqours. She first appears in the seventh episode of the first season alongside her sister, challenging Aqours at the Love Live regional competition. Saint Snow eventually disbands in the ninth episode of the second season, but Leah's personal growth continues as she becomes more open and confident in her own relationships.

Key relationships include her sister Sarah, with whom she shares a strong bond built on mutual support and family loyalty. Her interactions with Aqours, particularly with the first-year members, help spur her social development. Through these experiences, Leah evolves from a shy, competitive loner into someone willing to trust others and form new connections.
