U's Diary (Ｕの手帳, U no Techō) is a key item held by Yew Geneolgia in Bravely Second: End Layer. Just like D's Journal, it houses important information on monsters and items he and his party come across. It also contains an event viewer and help manual. When Yew decided to go on a mission to save Agnès Oblige from Kaiser Oblivion's clutches, Alfred handed him this diary, which is apparently Yew's treasure and most prized possession of all.
