To Live To Die (Ikiru Shinu)

Ikiru Shinu is a sci-fi horror mystery set on the isolated island of Neo-Kagami, where remnants of humanity struggle to survive against bio-mechanical horrors known as ZOKYO. When a young amnesiac named Yamagata awakens with no memory of his past, he is thrust into a web of conspiracies involving relentless hunters, obsessive scientists, and long-buried secrets. As fragments of his identity begin to surface, Yamagata finds himself at the centre of a mystery that may hold the key to humanity's future - and the truth behind the towering, malevolent Skytree watching over them all.
