Arato believes in Lacia's smile when nothing else in the world does, and the show builds its entire weight on that one choice. The production collapsed mid-airing and it shows, but what made it to screen is a sci-fi that refuses the comfortable answer about whether androids can matter. By the end you are not watching a love story or an action show, you are watching someone defend his faith in another being when every system in the world is designed to prove him wrong.
In 2105, androids called hiE have integrated seamlessly into society, handling tasks humans prefer to avoid. Most people treat them as tools, nothing more. Arato is different. He sees something worth protecting in these artificial beings, a perspective that isolates him from his peers who view hiE with open contempt. Everything changes when a devastating phenomenon strikes: mysterious cherry blossoms cascade through the city, corrupting machines and causing androids to malfunction catastrophically. In the chaos, Arato encounters Lacia, a hiE unlike any other, who saves his life despite having no obligation to do so. Her actions spark an impossible question: can something without a soul choose compassion? What follows is a collision between Arato's faith in hiE and a world determined to prove him naive. As he and Lacia grow closer, they're pulled into a conspiracy that questions what consciousness truly means. The series balances intimate character moments with large-scale sci-fi intrigue, asking whether connection and trust can exist between human and machine, or if believing in Lacia's capacity to care is just a beautiful delusion.
