Hiroyuki's watching the person he loves forget him entirely, reset to factory settings. The show takes that premise, the cruelest sci-fi premise it could, and refuses to make it easy, Multi comes back, but she's a stranger wearing a familiar face, and the quiet horror of that is the entire story. By the final episode, you understand why people who grew up with the original series wept: this isn't a story about getting your friend back. It's about accepting that some versions of people only exist in memory, and learning to say goodbye to them twice.
Years have passed, and Hiroyuki and Akari stand at the threshold of adulthood alongside their closest friends. Everyone has changed in subtle ways, marked by time and growing pains. But something vital is missing from their world: Multi, the android who once felt like family, has vanished without explanation. When Multi reappears on campus, the reunion should feel like a gift. Instead, she arrives transformed in ways no one anticipated. The girl they knew seems to have slipped away entirely, replaced by someone wearing her face but carrying none of her memories of their shared past. Hiroyuki and Akari must confront an uncomfortable truth: sometimes the people we love can return to us as strangers. What unfolds is a bittersweet meditation on growing up and letting go. As these high schoolers navigate the gap between who Multi was and who she has become, they discover that holding onto the past isn't always possible, no matter how desperately you want to freeze time. Some connections demand the courage to accept loss, even when reunion seems within reach.
