An info that isn't really fun to write, indeed Iiki no Ki has ended on March 28 with 24 chapters and 1 extra. I added on the website the title pages of the last 2 chapters and 2 scans of the latest pages, beware of some spoiler there. Nothing is planned by Kodansha before 28th November 2013 regarding sensei besides the release of Iiki volume 6. Perhaps will she write another Ludwig in the meantime? *dreams* xD
