When a devastating storm tears through the city, Elias begins experiencing impossible visions—flooded hallways, abandoned hospital rooms, faceless children, and a haunting woman whose whistling echoes through the rain. What first feels like grief and trauma slowly reveals itself to be something far older and far more terrifying. As reality begins collapsing around him, Elias discovers an endless dream-world hidden beneath human loneliness itself: a place where forgotten children, broken memories, and abandoned souls are gathered by an ancient cosmic entity known only as the Mother Below. The deeper Elias falls into the nightmare, the more he realizes the storm was never natural. It was searching. Now, trapped between reality and a living dream, Elias must fight to save his daughter before she is claimed by the endless world beneath the rain—a place where suffering becomes memory, memory becomes identity, and forgotten people never truly disappear. Blending psychological horror, cosmic dread, emotional tragedy, and surreal dreamlike imagery, this manga explores grief, isolation, family, and the terrifying human fear of being left behind. A dark supernatural journey through flooded worlds, endless hospitals, and living nightmares— where even monsters are born from loneliness.
