Maya Walker is a Canadian ice hockey player recruited by the Kushiro Snow White team to fill the center position vacated by departing star Yu Kiyose. Recognized as one of the world's best in her age class, her recruitment aimed to sustain the team's competitive strength after losing their ace. She stands 172 cm tall with blonde hair and yellow eyes, frequently wearing a tracksuit, and her birthday is December 25.

On the ice, Walker demonstrates exceptional agility and speed, enabling her to outmaneuver opponents effectively without relying on teammates. She plays with high confidence and an aggressive style, often prioritizing individual plays over team coordination. As Snow White's primary offensive weapon during the All-Japan Ice Hockey Championship Group B Finals, she scored the opening goal against the Nikko Dream Monkeys, showcasing her technical skill and athleticism. However, her self-reliant approach causes friction; teammate Eri Yamanaka criticizes the team for over-relying on Walker's abilities, mirroring the dynamic that preceded Kiyose's departure.

Walker's playing style and attitude serve as a narrative foil to Yu Kiyose. While Kiyose evolved to embrace teamwork with the Dream Monkeys, Walker continues operating independently. This contrast culminates in their direct championship match competition, where the Dream Monkeys' coordinated strategies ultimately counter her solo efforts. Her confidence borders on arrogance during gameplay, a trait framed as both a strength and potential weakness.

Off the ice, Walker exhibits a vibrant, energetic personality. She enjoys music and approaches life enthusiastically, contributing a dynamic presence within the team environment.
