Book

The book is a talking book that lives in Raenef V's Castle. His full name is Yohaim Alexis Fernando Reinhardt Wyferon Versaillas de Granvirias". However, he permits Eclipse and the others to simply call him "Granvirias" for short.

Raenef V first met him when he was desperate to become a true Demon Lord. The book used its powers to unleash Raenef's darker side. Eclipse and the others discovered the book while looking for the reasoning behind Raenef's strange behavior. The book said he wasn't able to return Raenef V to his original self. Raenef IV, angered by the book using Raenef V for entertainment, punished the Book by banishing it. Once the Book was banished, Raenef V was returned to his former self.
