A story of Shokuhou Misaki based on the events depicted in New Testament Volume 11.
I had first encountered this over on Danbooru, where some time after it was first posted, it got an English Translation (sort-of; those familiar with how works on Danbooru are translated would understand). This is merely my rendering of an almost word-for-word translation for posting here.
The following disclaimer is particularly for those (and yes, that would include myself to a degree also) whose preferred "ship" is or might be "Touma x Misaki"; as stated on the last page, this is entirely a fan-produced work. So, please don't interpret anything depicted here as being official canon.
