Ryuu to Yuusha to Haitatsunin Shikaban竜と勇者と配達人 私家版; The Dragon, the Hero, and the Courier: Self-Published Edition

Bonus chapters that never made it into volumes, infodumps, behind-the-scene stories, new bonus chapters, and much more from "The Dragon, the Hero, and the Courier", a rather strange medieval fantasy manga. This book was self-published by the author with permission from Shueisha.
