Just finished reading Ikigami: The Ultimate Limit. I have been reading this manga slowly since 2011 because I have been collecting the Dutch versions. I've always liked the story, however the last two volumes (which I finally read) were not so good. The first chapter states the story takes place in Japan and suddenly, from Volume 9 onward, it takes place in... Not Japan. There's suddenly this new place that is an exact replica of Japan and Japan is suddenly this foreign country the protagonist escapes to in the end. Maybe this is a mistake on the Dutch translators' side, maybe they missed that the story didn't take place in Japan after all.
Also, in Volume 9 there suddenly is an immediate war threat, while the relationship with other countries wasn't even touched upon in the first eight Volumes. It's also a change of plot that feels unnecessary, and this war thing especially because the mangaka didn't need it to advance his plot and the ethical issue he wanted to address. The story was already strong enough as it was but with this he kind of brought it down to just a conflict of dying for your nation and whatnot. Kinda overdid it.
An unfortunately bad writing decision to an otherwise good story. The first volumes are definitely re-readable.
