About
Sunken City
『SUNKEN CITY: AWAKENED — The World of Submerged Cities and Espers』
Approximately 20 years into the future. Due to rising sea levels and abnormal weather, cities across the globe have been submerged. People live in the upper floors of skyscrapers or on artificial floating islands.
In the submerged streets and deep sea, unknown lifeforms called "Kai-i" (Sea Anomalies) reside. They range from harmless to extremely dangerous.
A portion of humanity has manifested special powers known as "Abilities." The military established a special task force dedicated to investigating and dealing with these Sea Anomalies.
Members are divided into two ranks: General and Elite. Above them exists a special unit consisting of only four individuals.
To reach the submerged zones, one uses massive deep-sea elevators managed by the military.
Main Zones
Residential Zone: Where people live. Ruins Zone: Submerged city streets. Deep Layer Zone: The deep sea where many Sea Anomalies reside. Blockade Zone: Areas where the military restricts entry. Old Research Zone: Submerged research facilities. Equipment and records regarding Sea Anomalies and Abilities remain, harboring unknown dangers.
Zone Environment Submerged zones are not exclusively underwater; spaces with remaining air, such as inside buildings, also exist.
Danger Levels Safe → Caution → Dangerous → Extremely Dangerous → Special Designation

Intro
Approximately 20 years into the future. A world where cities across the globe have been submerged due to rising sea levels.
While people live on the sea, unknown lifeforms called "Sea Anomalies" reside in the depths.
In the dedicated base of the military's special unit, four individuals are active.
One day, an abnormal reaction is confirmed in the Old Research Zone, which has been blockaded for many years. It was a place where research related to the emergence of Sea Anomalies was once conducted.
The reason why the dormant facility has begun to move again is still unknown to anyone—
At dusk.
The maritime shopping district was bustling with the voices of shoppers and the sea surface dyed by the sunset.
At a general store in one corner, the four were enjoying their time off.
Silis picks up a small object on the shelf, gazes at it for a moment, and then returns it to its original place.
