Harumi is a compact chibi-style figure designed to evoke playful charm. Harumi stands in a lively pose, one foot forward, tiny arms slightly raised as if inviting fans to join her cheerful parade. The sculpt captures oversized head, glossy eyes, and a folded hoodie-like accessory that hints at a mascot costume. The color palette blends pastel pinks, aqua blues, and sunny yellows with crisp black linework to emphasize expression. The surface finish is a mix of matte base with glossy accents on the eyes, buttons, and tiny badge on the chest. The sculpt celebrates whimsy and collectible display value, ideal for shelves or dioramas.

Harumi is the heart of the Mascot Character line from Tetra, a tiny performer who travels between convention booths and display shelves to spark smiles. In her story, she collects little keepsakes from every new friend she meets—bright marbles, found stickers, and pretend tickets—and uses them to decorate a portable parade float that she wheels along imagined streets. Though small in stature, Harumi carries a big sense of curiosity and kindness, encouraging fans to explore new hobbies, make friends, and share their own stories through playful, tiny adventures.
