"Digital Native" is the first episode of the ChäoS;Child anime. It adapts the first chapter of the ChäoS;Child visual novel.
Six years after a massive earthquake devastated Shibuya, the city has been rebuilt and the survivors have continued with their lives. One of these survivors, Takuru Miyashiro, is a member of his school's newspaper club and is investigating a string of mysterious deaths, causing his foster sister Nono Kurusu to worry about him. Takuru then realizes the dates of the deaths line up exactly with the New Generation Madness murders that also occurred six years ago, and deduces that next death will occur today. He heads for a potential crime scene at a love hotel with his friend and fellow club member Serika Onoe, where they discover a girl waking up next to the bodies of two murdered men. The girl, Hinae Arimura, is taken in for questioning. Meanwhile, Takuru and Serika review the footage they took of the crime scene and notice the presence of a Sumo Sticker, an odd piece of graffiti that had mysteriously appeared in the city eight years ago. After learning that Hinae is a student at his school, Takuru heads to the Student Council room to investigate when he discovers that Hinae is in fact the president of the literature club. After Hinae confirms that Takuru was the one that found her at the hotel, she warns him that he will be killed.
