Complete re-write can be found here.
--------
After the defeat of the cyborg YONEKO in the hidden hallways of Special Task Force HQ, five teenagers-- Rekka, Tenmei, Koto, Yuuki, and Nagare-- resume their carefree lives. Oh, how they needed this break! The Frontier Quartet, having been arrested, won't trouble anyone anymore with their human/object hybrids whose name all had the letter "Q" in them. Suddenly, the STF undertake a mission to rid a library of the pesky "Q" hybrid things, when one knocks 'em all out cold. When they wake up, there's a new scenario which seems to get taking used to....
------------------
Based on the game "Little Buster Q" made by Tomy Corporation.
EDIT: Made teen due to slight gore, presence of profanities, presence of alcohol, semi-cartoon-style violence, and mild sex references.
SECOND EDIT: It's a bit late to post this, but the coverart was done by a user on iBrony. We were in an art trade.
THIRD EDIT: Being edited by this pony right here!
FOURTH EDIT: Drew the new coverart myself. I should do this more often. 
What is the franchise you are using for this crossover? It would be alot easier to understand certain things.
2895328 I listed it in the chapter select doohickey. And the game is in Japanese.

Hey Florarena just thought I'd let you know that your story was reviewed by Elderchaos... Here it is!
3816312 I saw the review and I told him I liked it.
This is one your most underrated stories here.
3843457 Yeah, but I do plan an update (provided I either get off my lazy ass or get an editor)
I feel as if I just tumbled down the rabbit hole. I realize it is that I am missing context of who these characters are... as such, and this is just FYI, I felt totally lost in what I just read.
8582839 Weeeeell... tried to re-write this fic (stand-alone, of course), and flopped. It may be a while yet before I revisit this a third time and fix it up.
In the meantime, the redo of Arcane Shadow's eating most of my attention.

No worries. I’ll try another one and see if I like it better.
8582855 I'd recommend the redo of Arcane.
