Tsukasa lernt bei einem neuen Auftrag eine Besitzerin einer Giftia kennen, die darauf besteht, den Körper der Giftia zu behalten und bereit ist dafür, alle Erinnerungen der Giftia zu löschen. Tsukasa ist darüber sehr verwundert und erkundigt sich bei seinen Kollegen darüber. Isla und Tsukasa machen die Bekanntschaft mit Andy, die ebenfalls für die SAI-Corp arbeitet.
During a retrieval mission, Tsukasa is surprised when the owner of the newly assigned Giftia opts to delete the latter's current personality and memories by replacing her OS and start over from scratch instead of handing over the Giftia proper, having done it several times already. Intrigued, he asks around the office if a Giftia who has gone through that experience is capable of retaining their old memories, but everyone replies there is no precedent to that. Later on, Kazuki announces that a marksman from the Terminal Service No. 3 office will be sent in, as the assigned Giftia and his owner have gone into hiding, and assigns Tsukasa and Isla to assist her. They later meet the marksman, Andie; shortly afterward, they have an awkward encounter with Eru, who mistakes Andie for her friend Olivia. After the mission is a success, Tsukasa learns from Eru that Andie is indeed Olivia, whose OS was replaced due to the company cutting costs. Later on, Eru tells Tsukasa that she reconnected with Andie and mentioned a carnival they used to go to together when Andie was still Olivia, which caused Andie to decide to go there. Not wanting to deal with her memories of Olivia, Eru tries to get Tsukasa to take Andie to the carnival instead. However, Tsukasa convinces Eru to come along, and they take Isla and Andie to the carnival the following night. There, Eru decides to let go of Olivia and create new memories with Andie, concluding it wouldn't be fair to either of them if she saw them as one and the same. Later, Isla gets lost in the crowd and Tsukasa begins searching for her, eventually finding her at a lonely walkway, terrified by exploding fireworks. After he consoles her, Isla brings up Andie and asks if her presence is hurting him. He replies that it does, but insists on continuing to be her partner. When she asks why, Tsukasa responds that it is because he loves her. Shocked and embarrassed by the sudden confession, Isla shouts that she cannot accept his love.
Tsukasa et Isla doivent aider Andy, un Giftia d'un autre service terminal, à récupérer une cible en fuite. Mais par le plus grand des hasards, Andy serait une vieille connaissance d'Eru, dont elle ne semble malheureusement pas se souvenir.
司遇到了希望更换回收对象Giftia的操作系统的拥有者。更换了操作系统的Giftia会不会恢复之前的记忆，虽然带着这样的疑问，但不论去问谁，回答都是“NO”。此时，第三终端服务所属的Giftia·安迪被派去搜索回收对象。看到安迪的样子时，艾露开心地说那是好朋友奥利维亚。然而安迪实际上是把寿命到期的奥利维亚的操作系统更换之后诞生的Giftia。
Tsukasa e Isla lavorano ad un nuovo caso, aiutando una Marksman molto efficiente che pare essere una vecchia amica di Eru. Tsukasa si chiede se i Giftia riciclati possano ricordare frammenti della loro vita passata.
La sección 3 del Servicio de Terminales necesita ayuda con una misión, así que envían a un tirador a la sección 1 para hacer la recuperación de una propietaria y su Giftia. Parece que Eru ya conocía a dicha tiradora, pero esta no la recuerda de ninguna de las maneras.
