Rogue is the screenname of the individual who is currently translating Monster Girl Quest from Japanese to English. Not much is known about the man other than him being a businessman in real life, and going on frequent business trips as a result.
He works tirelessly in terms of creating a reliable translation, completing 66% of the Chapter 2 translation in a matter of 2 months.
Rogue’s blog and the translation can be found at http://roguetranslations.wordpress.com/.
The last update Rogue made was on February 29th, 2012, stating that he is 78% done Monster Girl Quest part 2, as well as advertising translations for Violated Hero and Kamidori Alchemy Meister. Considering his frequent update schedule, many fans speculate him to be on an unannounced business trip, which is why he has not posted on his blog lately.
