Izumi to Ryuu no Zukan

"The Dragon Book" which thoroughly covers all dragon and shows adventurers the way to their dreams. Said book is a best-seller and a representative work of Sword and Friends & Co., but its contents are based on nothing more than the the dubious stories of adventurers that haven't been verified, as a matter of fact it's riddled with mistakes. The head of the editorial department of Sword and Friends & Co. starts planning a complete revision of "The Dragon Book." Two of which who were selected are a rookie reporter with a child-like appearance, Izumi, and the beastman bodyguard, Alf. Pursuing the truth about dragons, the compiling journey begins.
