Ok, so the principle would be like Liam on a Leash, but taller, same hight as our HA, like a partner. It can be all sorts of characters, or just Happy Budy Companion, Sad, Funny, Weird, Wizard, Groom, Schoolboy/girl, Boy/Girlfriend, whatever, imagination is the limit. I'd love for my HA to have a friend to keep her company :)

I believe there are CWs that fit the bill for this in some way or another, as well as and I imagine it would be a little hard to do a bunch of full-size companions due to the cramped space of human avatars.

On top of what said, there is also the item.
