One of the best mangas I've ever read and will ever read. I'm really looking forward to how the story will develop and what difficulties Nagai Kei will face. It's genuinely exciting to watch a whole world being confronted with such an alien creature in human form and reacting in fear. I just adore the simplicity of the concept of immortal individuals and simultaneously it's extremely fascinating. This author implemented the concept so well in an exciting story! I also appreciate the pleasant and a bit modest art (great foreshortening and epic scenarios).
In my opinion is Nagai Kei one of the most twisted and terrifying protagonists. And I love the way the author showed us his true side by letting his little sister being the only person who really knows and truly fears her own brother.
