Shino Buff Mice (ムキムキねずみ) are intelligent mice that work for Tengen Uzui.

Description
The mice are specially trained for the purpose of being assistants to Tengen and his acquaintances, as seen during the events at Yoshiwara, Tokyo. The mice are strong enough to carry one sword per mouse, and are capable of navigating small spaces humans normally wouldn't be able to.
