Kau, the one on the bottom with the white hair, from Togainu no Chi. He is one of the cosplay choices for Manifest 2011.
Personally, I'd do that cosplay (even though Kau is a dog...so? It means I get lead on a leash all day
).
The character itself is blind and mute, meaning that there is a significant risk of injury or even getting lost if the lead is given to someone else. I've already thought of wearing a placard with specific instructions on how I'm meant to be used (yes...
used) and communicating via rudimentary sign language (IE, rubbing tummy = hungry).
