Sprichst du Deutsch?? :( it's 5 volumes in total and besides the original japanese books I think the only publishers to fully translate them are German. I've looked for YEARS for original copies but can't find any. The full series is available online at manga %%% Dex dot org but it's a fan translation in Russian. Please let me know if you find anything else!
Ive only just recently ordered the Japanese prints because i loved it so much. And nooo i dont speak german, unfortunately, I've seen so far that there wont be any english translations in the future. Very sad:(( (excuse my extremly late reply, i have barely noticed this message). Good luck to the cult following on this manga.
Anywhere I can read? would love to finish this story(▰˘◡˘▰)
