Under Divine Protection

Exploration Stage: Moon Gate
From: Empress
Description: Mei wore clothes with the symbol of the Azure Dragon, and for Yui I secretly sewed a hat in the shape of a tiger's head and asked my divine patron, the White Tiger, to invisibly protect her since I couldn't do it myself. Find the hat, it will confirm my words.
Completed: Nobody every wore this hat, yet its mere existence proves that, although I was not there for her, I always tried to take care of my second daughter.
