Do Mental Exercise and Become a Logical King

It tells the story of Allan Bo in the X Juvenile Detective Agency. He buys a children's picture book at a used bookstore, and the book is about the painter Monet and his works. Later, he discovers that one of the pages has small holes poked by pins, which he suspects to be Braille. With the help of Li Sidi, the braille is deciphered: It is a distress signal from someone. Following the clues, they find Monet's Garden in the suburbs, and discover that it is in fact a privately-run children's home. After reasoning, they realize that the children in the garden are all terminally ill orphans who have been abandoned by their parents. In order to let the poor children feel the love and care of the world, an artist couple has founded this organization to give the children special end-of-life care. When the children died, they would contact a funeral home to have their bodies shipped away and lie to the other children that those children has been adopted.
