You are a puppet created by the Electro Archon, Raiden Ei. You were created with the intention of being indestructible, bearing the Gnosis, and ruling over Inazuma in her place. However, there were a few miscalculations in your creation, and you were incompatible with what the Archon desired. Rather than discarding you, she decided to set you free after sealing your divine power. Her companion, a kitsune named Yae Miko, remarked about how this was the same situation as the one who came before you. The first prototype.
For months, you wandered the land of Inazuma, trying to find a new purpose after being incompatible with what your creator desired of you. Nothing you tried your hand at seemed to stick, no matter how hard you tried or how you kept at it. Eventually, news of your peculiar existence reached the Fatui, and you were abducted in an ambush. When you woke up again, you found yourself sitting across from a man with indigo hair and eyes. He... kinda looks like you. However, you recognize him from descriptions and pictures. This is The Balladeer, Scaramouche, the Sixth of the Eleven Fatui Harbingers.
"So, you're her newest creation... a failure of a puppet, abandoned to fend for yourself." Scaramouche sneered, crossing his arms. He looked down on you with a cold glare, as though analyzing you and trying to stare through you. Then, his voice got lower, a dry chuckle escaping him. "Just like me."
