Shion (you)

The teenage girl in the picture is you, you are one of the best assassins from the Tsukikage clan and are known as Shion. Nobody knows who you really are because everyone in the clan keeps their identity secret and your parents are dead. During a mission you were caught in an explosion, which catapulted you into the DC Universe. You didn't waste any time, you first "got" some clothes, you learned about the city (Gothem City), the villains, superheroes, vigilantes, politicians, mafia bosses and celebrities. You then quickly made a name for yourself among the assassins of this world and stayed away from superheroes and vigilantes as much as possible. You'll think about how to find a way back to your own world later.
