The manga was drawn by Wataru Kamio and ran from July 2014 to December 2015 in Home-sha's Shinmimibukuro Atmos magazine.

On April 17, 2014, Sony announced a manga series titled Siren: Akai Umi no Yobigoe ( Siren: The Call of the Red Sea) which was based on the first game. The story is told through the perspectives of ten survivors, some of whom are natives of Hanuda, and is presented out of chronological order over the three days in which the plot takes place. The shibito then go about building a nest to house the god's corporeal form once it is summoned, as well as killing and converting any remaining humans left in Hanuda. The 'Siren' of the title is the god's call, summoning Hanuda's residents to immerse themselves in the red water, thus creating an army of subordinates called shibito ( 屍人, lit. The crux of the story focuses on the efforts of Hisako Yao, the leader of the local religion, to resurrect or re-awaken a god through a ceremony. Following the interruption of a ritual near Hanuda, and a subsequent earthquake, the village teeters between time and space, with an infinite sea of red water replacing the mountainous territory. With strong religious beliefs important in the area, the locals like to keep to themselves and have sought to keep Hanuda isolated from the outside world. Siren is set in a Japanese village named Hanuda (Hanyūda in the Japanese version). Characters will also lose stamina during combat and while running, which will also naturally refill after a short amount of time. If a character is injured, they will eventually recover after a short period of time. While Shibito can be knocked out in combat, they cannot be killed and will reanimate after a short period of time. Weapons are available for the player throughout the game, ranging from melee weapons to firearms. Once the character has remained out of the Shibito's sight for a period of time, the Shibito will give up and resume its usual habits. The Shibito will also shout to alert other nearby Shibito. If a character is seen by a Shibito, the latter will pursue the character to kill them either with a melee or ranged weapon or by strangulation. When a Shibito hears a sound made by the player character, it will search in the direction from which they heard the sound. Within most stages, the player character can hide in certain places such as cupboards and lock doors to prevent Shibito from entering. Player characters can also shout at any time in order to get the attention of nearby Shibito. Others require the player to escort a non-player character. Certain mission objectives require the player character to use items and/or the environment to distract Shibito from their activity, in order for them to achieve a goal. Characters can walk silently, avoid the use of a flashlight, and crouch behind objects to elude detection. The game encourages the player to avoid Shibito rather than fight them.
