The Student Council President Ichika explained what they were doing to the Principal. After listening to her explanation the Principal was quite surprised, he too was someone who graduated from this school and knew about the seven mysteries, but back then they were different. The Principal never expected that he would become one of the Seven Mysteries.
"I see, I understand what you were trying to do but that doesn't excuse you for coming into my office unannounced."
After some scolding from the Principal the members of the Occult Club apologized and left the Principal's office.

When they got out of the office the group noticed that it was already eleven O' clock and the time for the Dancing Shadow had long passed.
