"Shiroi Same no iru Shima" is a psychological thriller manga that explores themes of survival, morality, and human nature under extreme conditions. The story is set on a remote island where a group of high school students is stranded after their plane crashes. The island, initially appearing desolate, is revealed to be inhabited by a mysterious white shark, which becomes a central symbol of the students' escalating fear and desperation.

The narrative begins with the students attempting to organize themselves and find a way to survive. They establish a makeshift camp and ration their limited supplies, but tensions quickly rise as their situation grows increasingly dire. The group is diverse, with characters ranging from the pragmatic and resourceful to the emotionally fragile and impulsive. Their interactions and conflicts drive much of the story, highlighting the psychological strain of their predicament.

As days pass, the students discover that the island is not as uninhabited as they initially believed. Strange occurrences and the presence of the white shark suggest that something sinister is at play.
