Juno is a gray wolf and a first-year student at Cherryton Academy, where she quickly becomes a new and prominent member of the drama club's actor team. Physically, she is a tall and slender young wolf with a height of 170 cm, possessing a graceful and undeniably attractive appearance. Her fur is predominantly a dark, grayish-brown, contrasting with the white fur of her muzzle and the front of her neck. Her design features notably fluffy fur on her ears and cheeks, and she has a large, bushy tail. The creator, Paru Itagaki, designed Juno as a foil to another character, giving her more traditionally beautiful traits and a "fully mature" figure, with her face inspired by a young Winona Ryder.

On the surface, Juno presents a personality that is kind, sociable, and lively. She is described as having a natural charisma that allows her to quickly befriend her classmates and foster a positive, cooperative atmosphere within the drama club. She is an attentive listener and can provide thoughtful advice to those who are troubled. However, beneath this affable exterior lies a core of immense ambition and iron will. Once Juno sets a goal for herself, she pursues it with a fierce, relentless determination and is not afraid to be assertive or even aggressive in her methods. She can be quite competitive and possessive, particularly when it comes to matters of the heart and her aspirations.

Juno's primary motivation is twofold: to become the next Beastar, a student of outstanding character and achievement, and to win the love of her upperclassman, Legoshi. Her desire to become the Beastar is not purely for personal glory; she idealistically wishes to use the position to create a better world for carnivores, one where they can be celebrated for their strength rather than feared for their predatory instincts. This ambition fuels a rivalry with Louis, another Drama Club member and a leading candidate for the title. In a bold move, she confronted Louis, declaring her intention to surpass him and become the next Beastar while claiming Legoshi for herself.

Her role in the story is initially defined by her romantic pursuit of Legoshi. She falls for him after he comes to her defense when she is being bullied, an incident stemming from the fact she is a carnivore. Juno is proactive in her affection, asking Legoshi to help her with dance practice and using the opportunity to get close to him. She envisions them as the "perfect grey wolf couple". However, she ultimately realizes that Legoshi's heart belongs to a dwarf rabbit named Haru, leading to her painful but dignified rejection. Her feelings then gradually shift towards Louis, whom she initially saw as a rival. She becomes drawn to him, even going so far as to visit him in his new role as the leader of a carnivore gang called the Shishi-gumi and later sharing her first kiss with him.

Juno's key relationships are central to her character arc. Her dynamic with Legoshi evolves from an unrequited crush to a friendship where she sees him as a mentor, especially on the complex subject of interspecies romance. Her relationship with Louis is more complex, moving from rivalry to a deep, mutual attraction. Even after Louis reveals he has a pre-arranged fiancée, their connection remains a significant part of her story, as she must ultimately come to terms with his decision to part ways for the sake of his future. Her initial jealousy towards Haru, whom she saw as a rival for Legoshi's affection, transforms into a grudging respect and even friendship after spending time with her. Through Haru, Juno begins to understand the charm of herbivores and the challenges of love between different species.

Throughout the narrative, Juno undergoes notable development. She learns that her idealistic vision of a world where carnivores simply shine in the spotlight is not enough. While advocating for better treatment of carnivores, she also struggles with her own realistic belief that herbivores and carnivores might be better off maintaining a reasonable distance from each other, a viewpoint that makes her realize she may lack the true selflessness required to be a Beastar. Her experiences with unrequited love and the difficulties of interspecies relationships lead her to a more mature understanding of the world's complexities, teaching her about personal strength and the nature of acceptance. Her abilities include a natural talent for dance and performance, which she uses to captivate audiences and even communicate complex emotions, as well as the physical strength inherent to her species.
