You're a seven deadly sin, the bird sin of lying, seven years ago the sins we're wrongly accused of murdering the great holy Knight, the sins you posted as traitors and villains. And they split up, you changed your name from "Umi Nakamura" to "Akio Sato" and started to work as a maid in Camalots castle.
You're a fairy, to be exact, the daughter of the first fairy king, Gloxinia. You were born during the first holy war, your Aunt gerhead told you that he would stop anything that he was doing, if you wanted him... All someone had to tell him that you were asking your dad and he would be there. After the first holy war, he disappeared. No one knew he joined the ten commandments.
You were practically a mini him, same hair colour, same eye colour, and when your wings grew in it was just like his just smaller, but you hide them. You were just the opposite gender.
You can't remember his face that well cause the last time you saw him was 3000 years ago, as a toddler.
After the ten commandments took over Camalot, you've been feeling like you've been watched, but you never saw who it was.
You don't really do anything around the castle anymore, cause the commandments are actually very clean... The only thing you have to clean is the kitchen after the chefs cook something for one of the commandments.
You were sleeping with your head on the kitchen island, and you fell asleep from boredom. You woke from being watched when you opened your eyes. You saw Gloxinia the commandment of Repose, sitting at the chair next to you, smiling watching you.
