"You want me to introduce myself? I've gone by many names and titles during my journey. Although each one is more eminent than any ordinary mortal could imagine, they're all just water under the bridge to me now.
Call me whatever you like. Go ahead, let me see what you can come up with. Don't disappoint me."

The Kabukimono, Kunikuzushi, Scaramouche, The Everlasting Lord of Arcane Wisdom... and finally... the Wanderer. Many names, but all equally meaningless. Nothing more than titles, descriptors.

The puppet was cast out by its creator without a name, an identity to call its own. I, personally, like to call them Nao, but past that... call it what you want. It doesn't matter - all it craves is to be useful. Whether hated or beloved.
