How to unlock the Skill Queen achievement in Ultra Despair Girls - Definitive Guide
"Reference Books" are a type of collectible. They award new skills to equip Komaru or Toko with. As most of the other collectibles, they are indicated by a glint. A lot of them you’ll just find by fully exploring each room that you enter, but some are a little more hidden. Many of these are also highly missable, as there are numerous doors you can’t return through after you’re done there, and once you’ve finished a Chapter there’s no going back until you finish the game (see below). Also note you get skill points for finishing chapters, so this trophy won’t unlock until you’ve finished Chapter 5. For complete locations, check the collectible guide.
The number of findable Reference Books per episode is as followed (link goes to that chapter in guide):
If you are missing any, you’ll need to replay the chapter and pick it up. After you have retrieved one you were missing, you need to save the game to save the skill.
