Speaking Door

A Speaking Door (喋る扉) was located in the palace of Emperor Maya in Magic Land, appearing as an old mosaic painting of a woman. It served as the entrance to a chamber containing the Thanatos Cauldron, only letting those who correctly answered the question "Who is the most beautiful in the world?" enter. Haruto Soma and Kosuke Nitoh met the Speaking Door having sneaked into the castle. The two were stuck on the answer to her question until Haruto told the Speaking Door that she was the most beautiful. Though not the correct answer, the Speaking Door was wooed and let Haruto and Kosuke through.
