Moe Suzuya, nicknamed Suzu, shares a deep-rooted friendship with Mira Konohata, forged through years of attending the same schools and countless visits to Mira’s home. Their bond holds intimate knowledge, including Mira’s handmade romance book—a secret Suzu guards with playful mischief. Despite her family’s bakery, Suzuya Bakery, claiming her time after school, she remains a fixture in Mira’s high school life, delivering fresh bread to the Earth Sciences Club and lending a hand during festivals.

Bubbly and mischievous, Suzu thrives on turning mundane moments into chances for good-natured teasing, especially when witnessing friendships between girls. Her protective streak surfaces around Mira, prompting sharp scrutiny of anyone approaching her—harsh toward boys, dismissive toward girls. This vigilance mirrors her conflicted admiration for Mira’s older sister, Misa, whose presence coaxes Suzu into veiling genuine reverence behind exaggerated, joking affection.

Long violet hair adorned with blue triangular hairpins defines Suzu’s first-year look, a deliberate homage to Misa. By her second year, she sheds the length for a shorter cut, embracing a new self-perception as she transitions to a different class. At 165 cm tall, her physical shift doesn’t weaken ties to Mira, whose coined nickname "Suzu" replaces the bakery regulars’ unwelcome "Moe Moe."

Life outside school orbits the family bakery, but Suzu’s curiosity spills into crafting treasure maps and discreetly gathering intel on female classmates—hobbies that occasionally dovetail with the Earth Sciences Club’s antics or the newspaper club’s inquiries. Though not an official club member, she weaves herself into their adventures, joining summer camps or hot spring trips while steadfastly supporting Mira. Their friendship, layered with years of inside jokes and quiet trust, remains anchored in Suzu’s talent for balancing lighthearted jabs with unwavering loyalty.
