banken (inui toko)

A pair of dog-like companions to Nijisanji's Inui Toko.

The vast majority of the time they are just Inui's hair ornaments. Use this tag only when they appear in some other way.

They are individually named Ban and Ken, but are typically identical. Use those tags only when they can be identified.
For example, alongside Inui's 8th costume they each get a hat with their name written on it, and in Page of Lambda they are personified as dog girls with different hairstyles.
