"A metal plate with a ruby mounted on it."
— Description in the inventory.
The Ruby 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 Ruby Plate is located in different places according to the difficulty:
EASY and NORMAL
- In the west side of the Waiting Room, on top of a broken locker. The player must push the box on the East side to the West side, then go the other side. Then, the player must climb up the box and retrieve the plate.
- Inside the safe in the East side of the Waiting Room, which is the starting location in this difficulty. The player must do the normal process of pushing the box from East to West, but on the other side, retrieve the Ace Key, push the box again and then go back to the other side and open the safe with the key to retrieve the plate.
