Next in line is the extra chapter from the first volume, simply titled "Side Story".
As I said previously, the scripts that were left from the previous translator (thus "second hand") only go up to chapter 18- I need someone to translate the rest of the manga. Want to help? Drop a line in the comments. Know someone who would? Convince them. Or tie 'em up in front of their computer and threaten them at gunpoint- whatever works, though it'd be nice to avoid violence :)
