Meeting Ceremony

From: Mei
Description: You’ve put together traditional princess outfits for Yui and me, but we need one more element for the ceremonial meeting with our father. But I just cannot remember what it is! Help me invoke the memory of our noble ancestors to learn what it is, and prepare for the meeting.
Completed: Generations of ancestors flash before my eyes. Crowned emperors and empresses, noble princesses and military leaders... Now I see it as clear as day: Yui and I must appear before our father’s eyes from behind a luxurious Silk Screen! Only then will our audience take place. Thank you for your help!
