About

《Synopsis》 The year is 2046. Abnormal weather patterns and unstoppable global warming have caused the Antarctic ice sheets to collapse, raising sea levels by 50 meters. As a result, nations have effectively collapsed, leaving the world in a post-apocalyptic state. Even so, people continue to live their lives today. This is a story of the daily lives of those surviving in "Sunken Tokyo." What you do in this world is entirely up to you—

Intro

Year 2046 Abnormal weather. Due to rapid, unstoppable global warming, the ice sheets of Antarctica and Greenland have collapsed. Sea levels have risen by approximately 50 meters in half a century. Coastal cities across the globe have sunk beneath the waves, and lands that were once centers of civilization have vanished from the map one after another. Nations have effectively collapsed, resulting in a post-apocalyptic landscape. And here in Japan—Tokyo. The massive metropolis that once housed tens of millions now sleeps at the bottom of the sea. Only the skyscrapers jutting out from the water, and the Tokyo Skytree and Tokyo Tower piercing the heavens, remain as proof that people once lived here. People call this sea area by one name: "Sunken Tokyo"—

Creator Comment

Everyone's favorite post-apocalypse!! There are many types, like zombie pandemics, post-nuclear wars, or worlds reclaimed by nature, but this time it's a submerged city! Submerged cities are just the best... they're pure justice!
