Here's Shirogane again, this time showing her clothed, daily life self.
As you can see, she's far more refined and lady-like than when she's doing her ninja duties.

Shirogane wears a kimono designed after a Bronzong, and tends to carry a traditional umbrella with her, which is also actually her weapon of choice.
The canopy of her umbrella functions as a scattershot weapon. The handle contains a concealed blade, and finally, the curve in her umbrella functions as a pistol. Her umbrella also contain handy gadgets like a grappling hook to scale buildings with.

Shirogane usually spends her days in her garden among falling cherry blossom leaves and wild Pokémon, who help her tend to the garden.

The pictured Pokémon represent the Imperial Regalia of Japan: Honedge the sword, Bronzor the mirror and Comfey the jewel. Or to keep the Okami theme going: Glaive, Mirror and Rosary.
