Where can I buy Bible Black: the Infection?

I hope I'm not in the wrong thread =x if I am, really sorry!

So, I freaking loved Bible Black, I bought it in physical version, and was awesome as hell >_< the game is 14 years old and it was one of the best plots I've seen in an hentai. It felt more mature than other stuff I've read. (my opinion).
Also, I can't read japanese (yet!) so, I don't play any recent hentai game that isn't in english =x

Anyway, I want to play Bible Black: The Infection (english version) but I want it physical... where the hell can I buy it? I usually buy all my stuff on J-List (no complaints) but they don't have the sequel =x
Help... please... I want the sequel really bad =<

Thanks
