The All-Night Mask is a mask designed to keep the wearer awake all night. While it was originally designed as a torture device, it has found uses for keeping people up for parties or particularly boring stories.
Location
You can purchase this mask from the Curiosity Shop in town for 500 rupees on the third day. This mask will not appear if you let Sakon successfully steal from the Old Lady on the first night.
Uses
This mask only has one use in the entire game. There is a point where you can get into Anju's house and his grandmother will tell you stories. If you wear the mask, it will keep you awake through the stories. By answering the questions following the first two stories correctly, you can get a piece of heart for each.
