He reveals that the Majestic Twelve will be the one to fight him. Dr. Riddles then asks Kiyo to solve a riddle. After he answers correctly, Dr. Riddles and the Majestic Twelve leave. Dr. Riddles returns later and challenges Kiyo to a Mamodo battle. He reveals that if Kiyo defeats him, he will reveal the secret of the book.
