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

In Demon Slayer: Kimetsu no Yaiba, even when the story gets intense, there’s always room for those unexpected details that make the world feel alive. The Muscular Mice are exactly that kind of memorable side presence, mixing a straight-faced attitude with a hilariously offbeat look. This official Muscular Mice (A) figure is made in PVC, part of Banpresto’s Fluffy Puffy line, and stands around 7 cm tall, making it an easy fit in any Kimetsu shelf setup.

In the series, these buff little mice are mostly tied to Tengen Uzui, helping him out by carrying gear and slipping around like efficient little assistants, all while looking absurdly serious. They add a lighter beat to the story without feeling like pure decoration. This figure leans into that vibe with a determined, slightly show-off stance that feels like a tiny “ready to work” mascot.

Visually, it’s a light gray mouse with a fluffy-looking surface, oversized round ears with soft pink inner panels, and huge black eyes. The snout has a small bluish-gray round nose with short purple whiskers. It wears a blue headband tied to the side, topped with a cream plate featuring three gem-like shapes. The pose is a classic flex: arms raised to show the biceps, with a clearly sculpted muscular torso and darker shaded legs. A thin pale pink tail curves out to the side.
