Silence Suzuka is a running prodigy dominating races with intense, seemingly aloof focus. Her identity revolves entirely around running, though she gradually learns to forge meaningful bonds. Initially awkward, she becomes roommates with Special Week, their friendship deepening through shared training and competition.

She possesses long reddish-orange hair, a white headband adorned with a star, and green ear covers featuring her signature ribbon. Her attire is a collared white dress accented with green and yellow stripes, gold clasps, and a navy-blue bow. Her mismatched heels—one white, one brown—directly reference her real-life counterpart's hoof colors.

Beyond Special Week, she maintains a connection with Air Groove, her former Team Rigil teammate, and counts Machikane Fukukitaru as a friend. Her reserved yet authentic nature draws others in, though she seeks solitude to concentrate fully on running.

Transferring from Team Rigil to Team Spica in Season 1 seeking greater understanding, she suffers a fracture during the Tenno Sho Autumn race. This injury sidelines her for nine months of grueling rehabilitation. Wrestling with doubts about regaining her peak speed, she perseveres. Her triumphant comeback sees her win an open special race (likely the Capital Stakes) by a commanding margin, reaffirming her elite status.

Season 2 depicts her traveling to the United States, primarily keeping in touch with Team Spica via smartphone displays. She eventually returns to Japan, though her specific activities abroad are not detailed.

Gameplay highlights her "Runaway" racing strategy, excelling when leading. Her story campaign culminates in a victory at the Tenno Sho Autumn, a story-defining triumph that inverts the real-life outcome where her counterpart never finished. She habitually turns left when possible and stocks multiple identical pairs of shoes. Her journey consistently emphasizes resilience through adversity, particularly her injury recovery, while upholding her core identity as a dedicated runner.
