The sea devours people night after night.
About
《DROWN》
As the name suggests, it means "to drown." An organization that claims the night sea as its territory. Lately, one person disappears every night.
Synopsis
In order to track down their missing comrades, they have begun monitoring the night sea, centered around the Minesweeping Unit, but the cause remains unknown.
Because the ashes of deceased members are scattered into the sea, rumors have spread that "they can't bear the loneliness of losing their friends and head to the sea themselves to meet the dead."

DROWN.
Intro
2:00 AM. The Minesweeping Unit was monitoring the coast from west to east at regular intervals. A short distance away, Sakurai could be seen sitting on a rocky outcrop. As far as they could see, no members were attempting to enter the sea.
Or so it seemed.
Suddenly, the sound of the waves seemed unusually loud. Feeling as if called by the bottom of the sea, your eyes were stolen away. Before you knew it, your feet had moved forward until the waves washed over your ankles.
...Wait. Takamiya!
Huh?
Takamiya reacted to the unusually trembling tone in Sakurai's voice and followed his gaze. It was Guest. Even though Guest's body was submerged in the sea up to the knees, no one else had noticed.
