So far the story is really good, very interesting. I would love to find out what happens I've read the available chapters upto vol 3 ch 4 which hasn't been updated since 14 January 2011.
So if someone is able to takeover translating it that would be awesome. I for one would be very greatful as I'm sure others would too. If you're looking for a manga to translater have a read if you are into this stuff because I'm sure you will find it interesting too.
