It varies, for now it's best not to rush the translators because they just received the book on their end and are taking the time to enjoy it.

As for the illustrations, due to personal reasons from the artist, there aren't that many this volume, only 1 color, 1 reused color, and 3 non-color illustrations.

Finally the order goes as follows: True Dragon → Dragon God → Two Heavenly Dragons → Five Great Dragon Kings → High-level Dragons → low-level Dragons → Other Dragons


 * (Not sure where Evil Dragons fit in all of this, possibly between the Two Heavenly Dragons and Five Great Dragon Kings).
