Alice, a girl who was having her sister read the Osamu Tezuka Manga Complete Works in the forest, chases a rabbit that suddenly appears and falls into a hole--but it's a terrifyingly deep hole, and it's hard to reach the bottom. A phoenix visits Alice, who is attacked by sleepiness, and gives her a quest to "Find a way to return to the original world from Osamu no Kuni". What will Alice's fate be...? A new representative work by Kentaro Ueno, which is packed with material from Tezuka Osamu's huge collection of works and has a great impression at the end, is born here! At the end of the book, Mr. Taro Minamoto's commentary is also included!
