Aoba Moca, Haneoka Girls' High School’s third-year lead guitarist for Afterglow, drifts through life with a perpetually sleepy demeanor and languid, monotone speech. Her relaxed charm masks a mischievous streak, often teasing friends until others step in—a dynamic balanced by unwavering loyalty to her bandmates. Childhood bonds with Afterglow members run deep, especially with vocalist Mitake Ran, though she extends her circle to include Poppin'Party’s Saaya and Roselia’s Lisa, coworkers at a local convenience store. Sporting cropped ivory-blonde hair with tousled bangs and piercing blue-grey eyes, Moca’s tomboyish style leans into oversized hoodies and short shorts. She spins quirks like breadcrumbs dusting her cheeks into calculated charms, embodying sly confidence. This self-assuredness extends to her encyclopedic knowledge of baked goods, particularly Yamabuki Bakery’s offerings, which she can identify blindfolded by taste alone—a fact she casually drops into conversations. Behind the playful banter lies a dread of upheaval, especially within Afterglow. Subtle anxieties emerge when Ran pursues interests like flower arranging, sparking fears of being left behind. Moca labels this reluctance to confront relational shifts as her "cowardice," contrasting her usual boldness. Her metabolism defies logic, enabling endless snacking without consequence, while shounen manga collections clutter her space and inspire impromptu roleplay. She even naps upright, defying gravity between classes. Moca thrives on absurdity, whether jokingly claiming a body swap with bandmate Tomoe during Halloween or conjuring whimsical fixes during rehearsals. Conversations zigzag through non-sequiturs and manga-inspired nicknames, yet through the humor, a steadfast commitment to preserving her friendships remains central—even as she quietly battles the fear of their dissolution.
