I did this one just for Shizuku Murasaki. I love the dumb expression on her face and the easy way she gives in to sex. I started watching Hunter X Hunter just so I could figure out what was going on here and it turned out to be a pretty decent action anime. With that said, I still don't quite understand the setup (chalk it up to hentai logic I guess, or maybe it's because I got impatient and translated this before I finished the series, but at the moment she's got reason to help a hunter).
As for the other girls, I don't really know what's going on there because I haven't seen their shows. If there are any mistakes or improvements, please do PM me so I can make corrections as necessary.
