God created the world in seven days. It only took one for humans to destroy it. Life as we knew it sank to the depths of the sea...until yesterday. We do not yet know this broken world or the reasons for its downfall left behind here. An earth where ruins drift about, with remnants of buildings, cars, traffic lights... Modern civilization was destroyed, becoming nothing more than debris wading in the sea. New ruins drift one after the other before our very eyes, the survivors who live on one of those decaying islands.

• Play from the POV of one of eight protagonists in each chapter and explore the dungeons, towers, and islands to uncover the deadly sins of the protagonists' pasts.
• Hunt for materials and food while fending off monsters in real-time battle environments; but don't forget to eat, sleep, and go to the bathroom (seriously, it's bad for your health and fatal for your party).
• With every life cycle lasting only 13 days, each clone's stats, abilities, and capabilities differ as they grow from youths to old age. Depending on how you die, you can even earn bonus upgrades for your next life cycle. Take advantage of each life to the fullest.
• Enjoy original Japanese and English voices and English subtitles.
