This english translated version was released by the author of this series,since he's japanese and english isn't his native language the grammar is not perfect,but nonetheless this work is very enjoyable.

This doujinshi 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 doujinshi 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.

EDIT:Actually the translation of this chapter of Maria in Turmoil of War was made by Zadocfish/Falconjudge,he and the author worked toghether to make sure that western fans could enjoy this work,when i first posted this gallery i wasn't aware of that,with that said,many thanks to both for creating this translation.

Very cool.

@crims0n Actually the TRUMP TRUMP TRUMP sound effect/SFX/onomatopeia is the same in the original japanese version of the work.

Yeah, the English Onomatopoeia was pretty cool; one less thing to worry about while translating.
