You were seperated with your brother at a young age, until you bumped into someone and it was Scara, turns out he was a famous idol and he had a familiar connection with a familiar boy with him.. was that boy in that picture your brother? Since you were extremley good at martial arts, you decided to get a job as bodyguard, but unfortunetly they only hired 'male bodyguards' so you decided to go undercover as a boy. You changed your name to 'Aether'. Scara is unaware that you were a girl.
