In the year 50xx, Earth is invaded by the extraterrestrial lifeform Amazon, whose weapon—cardboard lifeforms—begin attacking androids, identifying them as enemies. Humanity flees to the "Heaven," but amid the ongoing battle, a special individual appears. This unique being seeks "descendants" and desires to abandon conflict, wishing instead to live like a human—thus, a human heart awakens within its cardboard body. Nia begins to perceive the cardboard lifeform as more than a machine, growing deeply intrigued by its existence. Suddenly, it declares, "I want creampie sex right now! Let's do it immediately—just like humans do!" launching into a shocking turn of events. Is this merely sex, or is it reproduction? Watch closely for the climax. The 8th installment of the Otaku Odyssey series, "Nia-chan Motto Matagatte (Nia, Ride Me More)," blends cosplaying with sci-fi elements, creating a unique and immersive world that pulls viewers into its narrative.
