In 'Alice in Borderland', Arisu, a disillusioned young man, is suddenly transported to an empty, post - apocalyptic - like Tokyo which is the 'Borderland'. Here, the only way to live is by winning the cruel games. Each game has a specific set of rules and a playing card associated with it, representing the difficulty level. The characters face not only the challenges of the games but also moral dilemmas. For example, should they trust other players? Arisu and his friends gradually learn more about the nature of the Borderland and strive to break free from it.
Overall, Alice in Borderland is reasonably faithful to the manga. Some minor details might differ for the sake of the adaptation, but the core story remains intact. There are no major deviations that would change the essence of the original manga.
