Also known as: バンケン, バン, ケン
A pair of Dog-like companions and mascots of Nijisanji's Inui Toko.
The vast majority of the time they take the form of Inui's Animal Hair Ornaments. Use this tag only when they appear in some other way.
They are individually named Ban and Ken but are identical in appearance, except in Page Of Lambda where they appear as twin Dog Girls with different hairstyles — for those versions see Ban (Page Of Lambda) and Ken (Page Of Lambda).
