Princesia was in the Monarchy library, reading the book that Principe gave her, the library is suddenly full of Angels, Elite Angels specifically since they are doing research and training by reading.
"For some reason, I'm getting interested in this book, where did he get this book? The Lost Sheep," Princesia thought.
"There's also a lot of Elite Angels, I wonder what's up?" Princesia asked as she looked around.
She continued reading the book she was reading.
The Lost Sheep book is a story about a sheep that was lost and separated from the herd, going through many trials, difficulties, and near-death experiences that turned its pure white wool into dark grey, influenced by the emotions the Lost Sheep felt from all it experienced.
