From Johou Battle:

A Tiny, Tiny, Clever Commander, Nazrin is a mouse yokai skilled at finding missing items. She's got a massive army of mice at her command, all of them hungry (for food) to find treasure! (and food!)

She's also Shou Toramaru's sole follower, and only moved into the temple recently to be at Shou's beck and call whenever she's needed! This also lets her take on missions from Shou in secrecy, classified work... or work to save Shou from admitting she loses things. As skilled and boastful Nazrin is about her abilities,she's still timid.

Please forgive her for fighting from the sidelines this time.
