Adele Russell (エアデール•ラッセル) is Jack's older sister, whom he lived with in Solieu Village until he turned sixteen. A gutsy young woman, she took charge of his upbringing after their parents passed away. She is also the one who taught Jack how to use a sword. She can be strict but it is always for Jack's own good. In front of others, though, she is a perfect lady. It is not an act either - that is how she really is.
