Alice in Borderland Season 1 Episode 7 Plot Summary and Synopsis
After finding a dead body on the ground, the players are told the rules; all of them have to work together to find the hidden “witch”, throwing the suspect into a bonfire to win. With only two hours to search for the killer, Aguni and his militants decide to throw everyone into the fire to collect the final card.
As dozens of people are murdered, Usagi teams up with a group of players to search for Arisu. After the building is lit on fire, Usagi finds and rescues Arisu. In the process, Kuina kills a dangerous militant known as the Last Boss, and Chishiya injures Niragi.
After thinking about the logistics of the game, Arisu tells the group that he knows the identity of the hidden witch. Throughout the episode, Ann figures out that Hatter was murdered, and later searches for fingerprints on the witch’s victim (identified as Momoka).
