Fifteen years have passed since Diva rescued the assemblyman, Momoka died in a plane crash, and Matsumoto beat the ever-loving shit out of Diva to prove the point that they can’t meddle excessively in the timeline. He had her body repaired and she returned to NiaLand, where she continued to perform and attracted larger crowds over the years.
She’s still wrestling with the concept of singing “with all one’s heart” when Matsumoto returns to report the next “Singularity Point” requiring action. He also scolds her for influencing the assemblyman to push for even more pro-AI human rights legislation. But the more pressing crisis is that of Space Hotel Sunrise, whose AI director crashes into the earth, killing thousands.
Matsumoto arranges for Diva to join the space hotel’s all-AI hospitality staff under the name Vivy, going Full Temporal Secret Agent in a thrilling space venue that calls to mind the Fhloston Paradise space cruise in The Fifth Element. She meets the director, Estella, and learns that she’s her successor model—essentially, her little sister.
While Estella reminds Vivy to keep smiling for human guests who may be on edge from being in space for the first time, Matsumoto’s assignment for her is simple: prevent Estella from crashing the Space Hotel Sunrise by eliminating her. The crash is a major catalyst in anti-Ai sentiment that will eventually lead to the AI uprising.
The problem is, Vivy simply can’t reconcile the Estella she’s met—and observes playing with children in a Zero-G bubble room—with the Estella later remembered as “the single most grievously defective AI in history”. Matsumoto considers this irrelevant.
They’re here to destroy Estella and prevent the crash; anything else is “needless calculations” he warned her about. Still, while fulfilling her hospitality duties, Vivy learns from her co-worker Leclerc that there are rumors Estella took over the hotel and was involved in the death of the previous human owner.
Vivy decides to investigate Estella on her own, but Matsumoto follows her into Estella’s quarters just as Estella arrives. When Estella picks him up, he prepares to hack her and cause a system failure, but Vivy casts him aside and asks Estella straight-up about the previous owner.
She maintains that the owner died in an EVA accident, which Matsumoto later confirms she had no involvement. Estella asked his family for permission to keep the hotel going under her management to keep a promise he made to him before he died. When she says anyone would laugh at an AI talking about such things, Vivy, genuinely moved, says she wouldn’t laugh.
Just then, an alarm sounds, some 23 hours before the crash is slated to occur. Estella runs a scan and determines a malfunction in a security wall. She asks the rest of the staff to double check all systems while she opens up the roof of the main hall to reveal the dazzling night sky. Then she sings a song to calm and soothe the stressed guests—a true professional all the way.
However—and this will probably be important next week—Matsumoto is right beside her when she opens the roof. Did he do something to her while they were in physical contact? Also, a girl recognizes Vivy as Diva and introduces herself as Momoka’s younger sister. For Vivy, that seals it: she isn’t going to let another Kirishima die, no matter what.
However, something is very rotten in the state of Leclerc, as she meets secretly with Estella in a cargo bay and holds out some kind of device Estella presses with her thumb. Moments later, as Leclerc walks away, Estella rushes up to her as if to gather her into an embrace, the shears Leclerc’s goddamn head off and sighs in a thoroughly sinister way.
This sudden carnage occurs while we’re still hearing Estella’s lovely song about the stars, providing a wonderful clash of the beautiful and the horrific. Whether it’s Leclerc who caused Estella to malfunction with that little thumbpad or Estella just snapped, Vivy’s trials aboard Space Hotel Sunrise have just begun.
