21g no Bouken

"Tsugiboshi" (The Splicing of a Book), in which a reader buys a book that doesn't exist; "21g's Adventure," in which the reader enjoys a walk in the air; "Interference," in which the reader begins to hear radio from a foreign country; and "Underground Library Exploration," in which the reader gets lost in the basement of a library. This book contains four exquisite low fantasy stories that invite the reader into a "mysterious world" that is connected to everyday life. (Source: Futabasha, translated)
