Demon Slayer Kimetsu no Yaiba - Muscular Mice figure (B), Fluffy Puffy

In Demon Slayer: Kimetsu no Yaiba, the world pits Demon Slayers against nightmarish demons, with a few unexpected helpers popping up along the way. The Muscular Mice are exactly that kind of memorable side presence, sitting somewhere between a visual gag and genuinely useful support on the field. This official Muscular Mice (B) figure is made in PVC, comes from the Fluffy Puffy line by Banpresto, and stands around 7 cm tall, making it an easy add-on to a Kimetsu display.

In the series, these “buff” mice are mainly tied to Tengen Uzui: they help him out, carry gear, and act as messengers, all while keeping a hilariously serious attitude. They bring a lighter beat into an often intense story without feeling like pure decoration. The figure captures that spirit with a simple challenge-like stance, a steady stare, and a compact “ready to work” vibe in chibi form.

Visually, it’s a light gray mouse with a fluffy-looking surface, big round ears with pink inner panels, and oversized black eyes. The snout features a small bluish-gray round nose and short whiskers. On its head, there’s a blue headband tied to the side, topped with a cream plate decorated with three gem-like shapes. It’s posed balancing on one leg with the other tucked up, front paws held in close, and a thin pale pink tail curving out to the side.
