This is an interpretation of machine translations. It is my first attempt at such. Nevertheless, it has been well-received. I hope you'll enjoy the story.
I read ahead and it ended up spoiling my enthusiasm for further translation work.

If you're thinking about doing translation work, I recommend this:
make a bookmark folder within your browser. In the following order, add these links:

http://translate.systran.net/
https://www.bing.com/translator
http://translate.google.com/
https://translate.yandex.com/

You'll have to submit an author title on NovelUpdates, but should be able to submit chapters shortly thereafter.
