Arata Kaizaki has undergone a transformation during his time as a high school student in the ReLIFE experiment. The experience has reminded him of the perspective he had lost as an adult and allowed him to form meaningful relationships with his new friends. Ryou Yoake, his support, cautions him that the experiment is fleeting, and once it ends, the people he's met will forget about him. Chizuru Hishiro is approaching the end of her two-year ReLIFE experiment, having grown into a more open and thoughtful person. Her life has been enriched by the relationships she's formed and the new perspectives she's gained. However, with the experiment ending, she and Arata must face the possibility of letting go of the memories they've made.
