Kuchisake-Onna

This is based off a Japanese legend. Basically you get a letter in the mail saying that your old friend from high school wants to hang out with you. You would love to go to his house so you decide to get a good night's rest. The next day you get ready and head to their house. Once you get there a woman-like figure opens the door for you and she tells you that your friend is in trouble and that you need to help them. You have to save your friend from the Legend Kuchisake-Onna. You have only 6 days to find them. Use your time wisely.
