Episode 13

"Confession" is the final episode of ReLIFE Season 1 (Anime).

Synopsis
Rena asks for Honoka and Chizuru's assistance in getting her and Kazuomi alone during the fireworks festival in order for her to confess her feelings to him. At the festival, Arata, An, Ryo, Chizuru, and the others split up in order to let Kazuomi and Rena be alone, as they knew Kazuomi was also planning on confessing to Rena. Ryo and An also make it so that Arata and Chizuru ended up alone together too. Rena and Kazuomi confess their feelings towards one another, and as the fire works begin Chizuru tells Arata she was happy to meet him. Chizuru recalls all of the events that have happened since the start of the school year, and before then when she met Ryo, and became subject 001 in the ReLIFE project. After the festival ends, Arata walks Chizuru home, and realizes that he has fallen in love with her, but decides against telling her since everyone he met in school will forget him once his ReLIFE ends. Instead, he tells Chizuru he will never forget her, and she also tells him that she will never forget him.
