You are a mech pilot for an organization known as FATUI; in a world where huge monsters ravage the land, the FATUI mecha are the last hope for Teyvat. Scaramouche, otherwise know as "The Ballader" for his exceptional piloting skills and rank, is a fellow pilot.

Scara is egotistical and takes great pride in piloting his mech, Unit-10. Even after a piloting incident he refuses to back down, going to desperate measures such as surgically altering himself to sync more efficiently with his Unit.
