Date A Live III

Shido faces Natsumi's impersonation scheme targeting twelve people close to him.

Following a hot pot gathering with spirits, Shido and the Fraxinus crew encounter a new spirit named Natsumi. Initially friendly, she abruptly declares her intent to ruin Shido's life and departs. At school, Shido is accused of various offenses by classmates and his teacher. He discovers that Natsumi disguised herself as him to damage his reputation. Before she can attack, Touka and Origami intervene, correctly identifying the real Shido and forcing Natsumi to retreat. Later, Kotori delivers a letter from Natsumi containing photos of twelve individuals close to Shido. The letter states that Natsumi has disguised herself as one of these people and challenges Shido to identify the imposter before all of them disappear.

Shido holds individual meetings with his friends to identify who has been replaced by Natsumi. He interviews Touka, Yoshino, Hiroto, and Yuzuru, concluding that none of them are Natsumi in disguise. The following day, before a scheduled date with Kotori, Shido discovers that Yuzuru was attacked by Natsumi and has disappeared. This urgent development forces Shido to act quickly to expose Natsumi and prevent further disappearances among his friends.

Shido dates Kotori, Kaguya, Miku, Ai Mai Me, Tama sensei, and Origami but fails to identify Natsumi, causing more disappearances until only four remain. The group brainstorms while Natsumi warns of three guesses. They consider if Natsumi is among the missing or not a person, with Origami stabbing photos to disprove the latter. Two wrong guesses result in Kaguya and Origami being absorbed by Haniel. Miku gives Shido her hair ornament, fearing disappearance. Recalling Yoshinon the puppet catching his phone, Shido deduces Natsumi disguises as the puppet. Natsumi loses control of Haniel, restoring the missing people and revealing her true form as a little girl. Enraged by exposure, she transforms the spirits into younger versions, shocking Shido.

Shido discovers Natsumi hates him for seeing her true form as a child, believing he will never care for her. Meanwhile, Origami is hunted by former employees until she agrees to work for DEM in exchange for details about a fire from five years ago. To lift Natsumi's spirits, Shido and the spirits take her shopping for clothes and makeup, demonstrating she can be pretty as a child, before DEM interrupts their outing.

Despair crashes down

Shido is captured by Origami who seeks revenge on spirits while Kotori battles Ellen.

Shido discovers that Origami has left the school and visits her apartment, where she captures him. Kotori begins searching for him while Origami explains that she intends to eliminate all spirits to avenge her parents' death, despite knowing they are harmless when sealed. Origami departs to confront Tohka and the others. Meanwhile, the Fraxinus is intercepted by Ellen, who pilots a DEM ship. Although the enemy vessel is superior in equipment, Kotori refuses to surrender and engages in combat. Throughout the battle, a restrained Shido pleads with Origami to cease her actions.

Origami travels back in time to kill Phantom but discovers she caused her parents' death.

Origami uses Kurumi’s untested Twelfth Bullet, Yud Bet, to travel to the past and stop her parents' death. She confronts Phantom, only to realize her own attack killed them, meaning the source of her revenge was herself. This revelation drives her into despair and causes her to fall into her Inverse form, Devil. As an emotionless entity, she attacks the hospital where Shido and the other Spirits are recovering. Despite support from the Spirits and Fraxinus, Shido cannot reach her with his voice. Kurumi then intervenes, sending Shido five years into the past in an attempt to alter history and save Origami from her tragic fate.

He subsequently wakes up in his bedroom, having altered the timeline.

He learns of an unidentified Spirit called Devil from Kotori, realizing she is Origami. The next day, Origami joins his class with a new personality. Shido investigates and finds she remained in the AST until retiring. During lunch, Origami mentions her parents died in a car accident four years ago despite being saved by someone who might be Shido's brother. Exhausted, Shido sleeps on the rooftop. Kurumi wakes him, revealing she retains memories of the previous timeline. When Origami finds them together, she transforms into her Inverse Spirit form and attacks. After Kurumi leaves, Origami reverts to normal but has no memory of the incident.

Inside Origami's subconscious, Shido breaks through her conflict with her old self, grabs her hand, and kisses her, reasoning she no longer needs to bear her burdens alone. This reverts her to her true Astral Dress. Kotori and the Fraxinus crew survive, and Shido returns to school while Origami and Tohka resume their previous status quo.
