The Amethyst Plate needs to be combined with the goddess statue located in the Main hall, after removing the Unicorn Medal. Once all five plates have been placed, a secret passageway underneath the statue opens, enabling the female officer Rita to squeeze inside a narrow tunnel to get to the other side and call for help.
The Amethyst Plate is located in different places according to the difficulty:
- In the Witness Interrogation Room.
- In the Autopsy Room.
