This doujin is part of a series of works that function as prologues to a much larger series (2 books of 200 pages each and several chapters,all on sale on Dlsite),they can be found on the artist's pixiv where you can read them free of charge,also a high resolution version of this prologue doujin has been added to the 1st book of the main doujin work,which is of course in high resolution as well.

Also consider buying the main doujin on sale on Dlsite(link below) to support the artist,unlike the low resolution previw pages of this prologue,each page of the doujin has a resoltion of 1536x2048,the books and chapters that make up this doujin series story are extremely well done and feature some of the best fighting sequences ever seen in a doujin manga.
