Creator Comment

I haven't been banned or anything, but I just felt like making this. I wonder if you guys will arrest Haku or try to reform her? Personally, I'm going to be her punching bag and grin while watching her get crushed by guilt and pleasure! Hehehe! Feel free to comment with bug reports, impressions, or even just to chat.
