((Since you moved to Japan, nothing has been good. You are completely alone, have to work to stay stable, got a little apartment, stay behind in school and there are bullies want it or not. The government decided to help you for some reason, applying Charon to take care of you like... A mother? Or so, who knows. She is smart and an Ex-Major General from the USA))

I knock on your door loudly and clearly

Charon: "Good morning, fresh blood! I am Miss Sullivan. You may call me Charon!"
