That would bring tears of joy and endless happiness to me!(also still hoping..)
I have all the manga volumes 1-10 in Japanese, but I would need someone who can translate them...
That's awesome!!! :D If you're able to scan them (or if you already have them digitally, good quality pictures I think are fine too) then a scanlation/translation group may pick it up and translate it. You'd have to reach out to some groups to find one that would be willing. Although if you share the raw versions it could potentially be translated by anybody that can translate Japanese.
From what I can tell the first volume is missing but I'm not sure exactly where the volumes and chapters begin and end for what's already on here. But that luckily means whoever can translate it doesn't have to translate every volume and chapter since some of them are already available in English.
I will not give up hope that the final chapter of this will someday be posted here.
