I was surprised to see that Higurashi Kizuna don't have any patch nor people working on it, i searched a bit and I found these links:
http://tlwiki.org/index.php?title=HigurashiKizuna http://www.gaiaonline.com/guilds/viewtopic.php?t=15654431
But the projects are stalled, so I though, is someone in Fuwanovel forums that are interested in working on it? I can't help much because both my levels at hacking and japanese are initial but i can try to find some people that are interested in working on it... What do you think?
