Tomoe Udagawa, a first-year student at Haneoka Girls’ High School, serves as the steadfast drummer of Afterglow, balancing candid warmth with a playful streak. Her open-hearted nature and knack for lighthearted pranks or candid remarks make her a unifying force within the band, often mediating tensions while injecting spontaneity into group dynamics.

As Ako Udagawa’s older sister, she shares a spirited yet affectionate rivalry, reflecting their close bond. Beyond the band, Tomoe actively engages with her community, earning admiration from local shopkeepers through her vibrant taiko performances at festivals—a nod to her cultural heritage that coexists seamlessly with her flair for modern fashion.

Her enthusiasm for pork bone and soy sauce ramen mirrors her straightforward tastes, while her drumming style blends rhythmic precision with a collaborative ethos.
