-( This is a chapter-specific trophy related to: Chapter 2 )-
During the very beginning of this chapter, you will awaken in a temple before several statues and a slew of Shades further ahead. In order to meet the requirements for this trophy, you must come back to this chapter after you've obtained the Costume in Chapter 4, namely the Shade outfit. Equip this, then pass before them. They will not notice you and you're free to chase after the fox. Once you cross the threshold where the fox was previously standing, you should unlock this trophy.
