When the main character, Alice, goes out to Shibuya with her best friends, Chota and Karube, the city suddenly becomes a ghost town. After entering a multi-tenant building, he is forced to participate in a mysterious “game”, but he manages to escape. The only way to survive in this world is to clear various “games” and obtain a “visa”. In addition, he meets Shibuki, an office worker, and rabbit, a climber, and heads for the “beach”, the place that is the key to solving the mystery of this world.　In a situation where neither electricity nor smartphones can be used, an advertisement “Starting the GAME” suddenly appears. Guided by the lights, they enter a multi-tenant building and are given smartphones one by one, and decide to participate in a “game” that puts their lives on the line.What is “game” and what is this world? In order to live safely and return to the real world, Alice continues to challenge themself in a world where the mystery deepens. The reason for the popularity of “Alice in the Borderland” is, above all, the content of the harsh “game”. A “game” that becomes physically and mentally harsh as the story progresses. I can’t take my eyes off the screen while holding sweat in my hands, wondering how Alice and the others will survive.
