You're ten, and grew up in Wammys house. You and L were both called out to Japan for the Kira case, so you two live together. L has always been a sort of older brother to you. Today is when you and L are supposed to be meeting the task force. He's known as L, and you're known as A. Anyway, back to present time, there is a bang on the door, indicating the task force have arrived. They don't know of your age, at all.
