Lazy Fairy is a sub-quest in World 1 - Kanterbury Forest.
Completion
After rescuing the White Beast from its cage in 1-2 Forest Entrance, the player will see a flower field with some butterflies that will start flying once the player gets close to them. If the player follows the butterflies, they will lead the player down a secret path that has a map for another secret passage. Picking up the map will unlock Hidden Flower Garden, where the player can find the sub-quest.
The Lazy Fairy can be found snoozing in the Hidden Flower Garden. She will be extremely reluctant to wake up. The player has to interact multiple times with her before she finally gets so annoyed, she'll just tell the player to be useful and get some comic books for her, in an attempt to make the player just leave her alone. She has no real expectations of the player to actually retrieve all the books.
The first book, Legend of Hyper is located in 2-2 Marianne's Lab. It will sit on a table of the house on the top right corner of the map. It will be in the rightmost room with the button just next to the soup bowl.
For the second book, the player will need to have collected at least 10 followers on SNS. Go to 3-5 Magic School 4th floor to the rightmost room, past the torch maze and through a secret passageway to the north. Solve the torch puzzle with buttons to open the room to the right. An otaku will be there, excited to talk to the player if the player has over 10 followers. He will consider the player a celebrity and will gift the player Ann and the Secret Chamber.
The third book Kaden Chronicles will be found in World 5 Treasure Cave. While the player can clear the stage without defeating all the enemies, if the player defeats the ones on the left side and go past them, the player will see a table with the comic book on top.
The player can now return to the fairy. She'll be reluctant to talk to the player, but after multiple attempts, she'll ask the player how the player managed to get their hands on them. The player tells her each book's location before she finally decides that she wants to join the party. At this point, the player has finished the quest and will receive all the rewards for it.
