I really like the Pretty Please, Kitsune Guuji? book in this event. It's obviously supposed to be a EiMiko story. Whether or not Miko herself wrote it is unclear although since she calls Raiden "My God" I wouldn't be surprised if she did.
For those who don't get it. Hu Tao has a chance to create an additional suspicious version of a dish when she cooks. Suspicious dishes are basically failed and/or bad tasting versions of the food which are much less potent than normal.
