I re-wrote the later part of the final arc and the ending, starting from about where Kurono takes the alien hostage, and re-writing everything after that:

I wanted the closing chapters of the story to reflect the brutal, harsh reality that made the earlier chapters so good. I was not a fan of KEI-CHAN/TAE-CHAN crying, but I didn't want to alter the fundamental truth that their relationship was a core part of the final story, I just resolved it in a different way that I think will have most of you going :-O or :-D or both.
The final war could have been the epic struggle it was built up to be, full of moral gray areas, tough choices, and sacrifice. The ending turns out to be a lot happier for some characters than others. Kurono gets a "happy" ending, but it isn't the ending he would have wanted.
This was a rough draft I wrote in 1 sitting late at night after I read the final chapters. It isn't perfect. I'm not that happy with the setting for the epilogue but I figured it would get the job done. I debated opening the epilogue with Kurono having a tender moment with Tae, only to wake up next to _______. I think I'd put something like that in a more polished draft to show that Kurono's ending torments him, but if I added all those detailed scenes, this would have been 20x longer.
