By accessing these different quests players will be able to learn all kinds of new things about the other playable characters. One such quest is Troublesome Work quest that Lisa allows players to complete a few tasks with her. This quest begins with Lisa asking the player to help her find some overdue books that have been missing for a while. This guide shows players how to complete the Troublesome Work quest.
Players will first need to follow the quest marker back to the main castle area of Monstadt. Here players will be able to find Lisa inside the library. After speaking to her she will ask the players to follow her to go retrieve a few overdue books from local people in the city. There are four total books for players to track down during the course of this quest, and each one is being held by a different person in the city.
The first book can be found at Monstadt Souvenir shop. After speaking to the shopkeeper Lisa will ask the player to buy them a gift from the shop. The thing that will make Lisa happiest is the Ragged Old Scroll, so players should pick this up for her. The second book is at the restaurant. Lisa will ask for something to eat here, and once again the dish that will make her happiest is the Radish Veggie Soup. The third book will be found at the flower shop, and once again Lisa will ask for some flowers. Players should purchase Cecilia flowers for her. Once players do all of this they will obtain the first three books.
The final book will be located by following an energy signature that appears on the ground. All players have to do here is follow the markers on the map until they track down the final missing book.
