That night, she confessed to him she was an angel, and that one of her duties was to dispose of ghosts.
She also told him she was willing to forsake her duties as an angel, in order to be with him. After seeing her sister leave, Panty tried killing the ghost off, but Stocking stopped her, telling her she couldn't understand her feelings, for she had never fallen in love before.
