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.
Main Article: List of all enemies in Bravely Second
Yew keeps detailed notes on the creatures his party encounters. By defeating the same enemy several times, he can learn and write more pages with all sorts of trivia and useful information. The characters can also be seen jotting down their comments and opinions about each monster.
