Adventures of Ugo (Anime)

History
The Adventures of Ugo is one of the books donated by William Minerva with a hidden message on its ex libris.

Upon closer inspection, Emma discovers that the dashes actually form Morse code messages. One particular book, "The Adventures of Ugo," has the morse code for 'promise.'

This book portrays the fantastical adventures of a young man Ugo and his lemur friend, Marvine, which depicts a fantasy-like world parallel to what the orphans experienced during their escape from Grace Field House in the Demon World. William Minerva intended for the escaped children to use the book as a guide book on how to avoid the hazards outside Grace Field House and how to survive in the Demon World.
