The Earth is about to pass through an unknown space filled with dark matter, and is about to experience the unbalance zone, a space where anything could happen...
DJ and Kagura are working space. Kagura notices an approaching UFO and tries to help DJ, but is blown into outer space when the UFO collides. At that time, HEART headquarters on Earth receives a report that the rock surface is moving. After hearing the screams of a monster, Captain Minato issues the order to deploy HEART Winner and HEART Warmer to the Aga Mine. Kagura, who miraculously survived the accident, also rushes to the mine. While the HEART team members are investigating the mine, Nana is trapped. As the mine begins to collapse, Ahnagarge, a mineral vein monster with rock-like skin, emerges from within, Nana on it's back. Kagura skydives from the HEART Winner to rescue Officer Nana. At that moment, the Ultra Sign with the word "Neos" appears in the sky, and a voice calls out, "Neos, Neos, Neos."
