Es ist der letzte Tag in Islas Leben gekommen und Tsukasa und Isla sitzen gemeinsam auf dem Dach und beobachten den Sonnenaufgang, während sie einige Tagebucheinträge Islas vorlesen. Sie entscheiden sich dafür, ihren letzten Tag im Vergnügungspark zu verbringen– Tsukasa fällt es sehr schwer loszulassen, doch Isla übergibt ihm ihren Deaktivierungsring...
It is the last day of Isla's lifespan and she and Tsukasa decide to first spend it by reading entries in her diary. They then spend the morning cleaning up their dormitory room and then taking a bath. They then head over to the office, where they take care of Isla's herbs and she leaves notes for the other employees. They are approached by an early Kazuki, who teases Isla for one last time. The two then decide to spend the day's remaining hours at the amusement park, which they enjoy to their hearts' content. Eventually, they stand at Isla's favorite bench, where she describes how she always observed the emotions of the park's many visitors and how contented they would be at the end of the day in bringing their happy memories home with them. Then, as the park closes, Tsukasa and Isla convince the operator to let them ride the Ferris wheel one last time after closing hours. There, they take turns describing what they love about each other, and Isla finally admits she loved the way Tsukasa held back his sadness and smiled, despite her worry over that characteristic. She then hands him her deactivation ring, saying that she wanted him to be the one to do it. Tsukasa begins crying, and Isla notes that it was the first time she ever saw him cry. He then puts the ring on, expresses his hope that she would be reunited with the person they cherished, and kisses Isla as her time expires. As he carries her to the vehicle, he is met by Kazuki, who thanks him for being there for her, which causes him to break down in tears. The other Terminal Service employees read Isla's letters, in which she thanks them for all the memories she had of them.
In the epilogue, Tsukasa takes the same elevator where he met Isla and muses what it would be like if his lifespan was predetermined, concluding afterward that he would live that life to the fullest. Nine months later, he returns from a training course to resume work with Terminal Service No. 1, and is introduced to his new Giftia.
Le dernier jour pour Isla est arrivé, il est l’heure pour Tsukasa de démarrer sa récupération.
アイラの回収日の朝。ツカサとアイラは部屋のベランダから二人で朝日が昇るのを見ていた。
二人で生活をしていた部屋を掃除して、いつもより早くオフィスに出社した二人を待っていたのはカヅキだった。
いつも通り働こうとしているアイラの社員証を取り上げ、「さっさと帰れ」と二人を追い返す。
最後の一日、二人きりの時間ができたツカサとアイラが向かったのは、遊園地だった──。
艾拉回收日的早晨。司和艾拉两人在房间的阳台上注视着朝阳升起。他们清扫了两人生活过的房间，比平常更早地来到办公室，香月在那里等着他们。艾拉想要一如往常地工作，但香月收回了她的职员证，对两人说“快点回去吧”。最后一天，得到两人独处时间的司和艾拉所前往的地方是，游乐园——。
È il giorno del ritiro di Isla. Tsukasa e Isla decidono di affrontare la giornata come tutte le altre, cercando di viverla fino alla fine con un sorriso.
Isla y Tsukasa disfrutan de su último día juntos, pero la perspectiva de la despedida no les arruinará su último día, el cual pasarán juntos disfrutando y compartiendo buenos recuerdos.
