Raspberry-chan is presented as a bright, chibi style mascot with a glossy raspberry red outfit and a tiny leaf-topped headpiece. The figure features oversized, expressive eyes with a gradient of pinks and violets, a cheerful wide smile, and a plump, friendly silhouette that emphasizes charm over menace. She wears a short, frilly dress accented with small seed-like decorations and a delicate white apron, along with cute, rounded shoes. Painted details highlight subtle shading in the sculpted folds of her dress and the gloss on her hair, giving the character a plush, soft feel. The base is a pastel, circular platform decorated with tiny berry motifs, enhancing the character's sweet, collectible appeal.

Raspberry-chan hails from a playful side world where hobbyists gather to trade figures and share dioramas. As the mascot of Blighted Blessings Mascot Character line, she travels between shelves and display cases to spark joy and inspiration among collectors. In her backstory, she guards a secret berry archive that glows when new figures are added to a collection, and she keeps a tiny notebook of friends she meets at conventions. Her personality is curious, optimistic, and relentlessly helpful; she cheers others on, often arranging mini parades of tiny characters on bases and encouraging budding collectors to display with care and imagination. Her adventures teach that every figure has a story and that sharing those stories is the true treasure of a hobby.
