Anime - style illustration of a group of young people standing in a city

A tense and dramatic book cover features five high school students—three boys and two girls—standing in a deserted city street at night. One of the boys, with a determined and focused expression, stands slightly in front of the group. Behind him, the girls and the other boys show a mix of anxiety and resolve. The city around them is dark and ominous, with tall, shadowy buildings and a few flickering streetlights. The sky above is cloudy and threatening, with a hint of the moon peeking through. In the distance, there are vague silhouettes of other students, indicating a dangerous survival game. The title of the novel is prominently displayed at the top in bold, gritty font, with the author’s name at the bottom. The overall mood of the cover should be intense and suspenseful, reflecting the life-and-death stakes of the story.
