This was so much fun to do.
I've always been a huge fan on Japanese urban legends and horror so I decided that Theodora would be Hanako from the tale of Toire no Hanako-san.
You must go to an elementary school at 1 in the morning.
Pick out a locked girls bathroom and go inside, alone.
Start knocking from the stall nearest to the entrance and ask; "Hanako-san, are you done yet?"
Then move on to the next. Continue until you hear a reply, "Not yet."
Once you hear it, stay knocking at that stall, still asking the same question.
When she replies "I'm done." the door will open slightly.
Open it, and you will see a young girl with bloody scars all over her. But hurry and get out because once she drags you into the stall, that's the end for you...
