This time you are in an old school where Slendrina at young age use to go to.
Try to find 8 fuses that are scattered throughout the school. The 8 fuses will be used to open a locked door. You must also find one of Slendrina's belongings and give it to her, to get something in return.
You also need to find keys to open certain doors and health boxes that give you a little more health when you have been injured.
