As a third-year student at Cherryton Academy, Shiira serves as lead choreographer in the drama club. She presents as a tall, slender big cat with yellow fur accented by brown or black spots. Her standard school uniform includes a white blouse with a bow tie, a long pleated white skirt featuring two light blue horizontal stripes near the hem, a thin tan belt, white anklet socks, and black Mary Jane shoes. Casually, she pairs a fluffy jacket with a black skirt.

Initially, Shiira voices sensitivity about carnivore-herbivore dynamics, advocating distance between species. Despite this, she displays innate kindness and openness to others' viewpoints. Her perspective transforms after befriending herbivore classmate Peach, where initiating their connection helps her discover shared ground and bridge species divides through genuine interaction.

In her choreography role, Shiira operates with confidence and assertiveness, commanding authority in the club. She halts idle gossip and prevents eavesdropping on leaders like Louis. While respecting Louis’s leadership and acting talent, she occasionally engages him with cheeky remarks, especially amid Juno’s rising influence. Shiira cultivates warm relationships with fellow female club members, balancing rapport with discipline.

Her youth involved financial hardship; at fourteen, poverty drove her to work as a dominatrix in a BDSM club to support her family. This period remains a notable chapter in her history.

Shiira mentors and befriends Juno, admiring her maturity despite their two-year age gap. She introduces Juno to Legoshi upon Juno’s club entry. As lead dancer, Shiira occupies a respected tier in the club’s artistic structure.

A discrepancy marks her media portrayals: the manga designates her a cheetah, while the anime adaptation renders her a leopard.
