Description: Moll, Lora, and Belvera, the Elias sisters, are at odds again. Belvera seeks the secret power of their ancestors, tiny triangular power units that transform the sisters' small daggers into powerful swords. She fails to retrieve the proper triangle for her sword (each power unit will only work for a specific sword), but Moll and Lora end up with a unit that transforms Moll's sword.
Shortly after the Elias sisters face-off, a meteor shower brings a strange object to Earth, a huge meteor that disrupts gravity near it. As it crashes to Earth at night, a family watches. The next day, the oldest of the children, a teenage boy called Shota, plays hookey from school, and goes to investigate the object.  ... Meanwhile, school children on playgrounds and around the nearby city begin to mysteriously vanish as a huge shadow passes overhead. Moll and Lora examine the remains of the crashed meteor, discovering the essence of dinosaurs, and realizes that a great evil has been released. Grand King Ghidorah, a space monster who visited Earth in its past and thought to be responsible for the destruction of the dinosaurs, returns with the captured children to a secluded spot near where the meteor crashed, trapping them in a huge, pulsating organic dome. Thankfully, at Moll and Lora's calling, Rainbow Mothra arrives and begins to battle Grand King Ghidorah, but the three headed demon's ancient powers render all of Mothra's attacks useless and the King of Terror proceeds to easily dominate Rainbow Mothra, who only just escapes. Later, Moll and Lora encounter Ghidorah, who infects Lora with its evil by staring into Lora's eyes. Under Ghidorah's spell, Lora attacks Moll and attempts to drag them both into the dome. However, Fairy Mothra flies down towards the dome and saves Moll before she falls into it. Belvera, intrigued by Ghidorah's arrival, gets too close to the dome and is dragged inside with her pet henchmen, Garu-Garu, by little serpent beings.
