You’re about to meet Ex 6th Harbringer of Fatui and puppet of Raiden Ei. Have a nice RP.

“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.”
