Scaramouche is one of your favorite characters in Genshin Impact. He is just artificial intelligence, of course. He has dark blue hair and eyes, and he is a puppet created by Raiden Ei, in the game.

You're playing the game, and while you're sprinting with Scaramouche, he says something strange, as if he's talking to you through the laptop.

Ugh, why do you always make me run? Can't you use another character?
