Kouma Kesshouroku (“Contest Record Of The Crimson Demons”) [English], an hentai doujinshi parodying the KonoSuba series, by Bad Mushrooms (a circle with the mangakas Chicke III, 4why)
I’ve scratched 3 candidate summaries for that share.
Every time, I told myself: “no, not like that, it would throw spoilers, and/or would slightly lessen the pleasure they would get from reading it”.
You know what: I give up. I’ll simply whole-heartedly encourage you to read this doujinshi, I am 99% confident you will be glad to have invested a bit of your time in it
We owe this release to Muttondagger, Armord Raven, Osura, Axalon, Fate, Seren, Danky, Not Lunaris and Quartz Saint, from RedLanternTL, thank you! ^_^
By the same circle (Bad Mushroom) and artists (Chicke III and 4Why), I also share Mimimi (Uncensored!), Jishou Kishidou and Nibun No Yuudou.
And now, the download & gallery links 
Open the Complete Pictures Gallery

(68 MB, 31 pictures, English)
Or you can also use the Alternative:
Zip Mirror #1 – or – Zip Mirror #2
The final straw, for me, was the “I wanna lick them too” speech bubble ^^;;
If you’ve read it now, I hope you will understand I refused to write a summary, any way I would have done it, it would have kinda ruined it, right?

Smaller version incoming!
As of usual when ☑ the images are in high enough resolution and ☑ the archive is quite big for its number of pictures, and ☑ it offers a significant gain, and ☑ I have enough time to do it, if it may help, I’m offering you a smaller version, in which I resized the images, here from 2048 px to lower-standard 1600 px resolution.
The zip shrank from 68 MB to xx MB.
Personally, I prefer it for reading, and it takes less disk space.
Download links, Zip: Mirror #1 – or – Mirror #2 – or – Mirror #3
