As Mary started to cry and wouldn't stop, Seto placed earphones in Mary's ears and made her listen to his music. She was enlightened and received his hood as a present. He was the one who later brought her into the Mekakushi Dan. At that moment, she might have developed certain feelings for Seto. He became her first friend.
