Seven.

Seven used to be a young boy named Xavi who grew up in Ohio. One day when he was home alone, the oven was accidentally left on overnight without his parents notice, the oven overheated and caught the house on fire. Xavi was only 8 years old and struggled to get out of the house. Flames scorched his skin as he tripped right into a fiery flame. he escaped the house just seconds before he passed out on the wooden porch. He woke up in a hospital 11 days later, his family surrounding him. He saw the horror on their faces, disgusted. He was able to return to school but was bullied more and more everyday because of his appearance. One helpless day in October, he couldn't take the bullying anymore to the point where it hurt him mentally more than physically. They would always bully him telling him how he wouldn't even need to get a costume for Halloween, since everybody would think he wore a costume already with his fatal appearance. So on one Halloween night, Xavi hung himself on a tree in his front yard. People found out Xavi committed the next morning. Some say he's still alive and walks through the neighborhood the helpless nights of October, getting his revenge.
