The mysterious life-form Zovaras is deeply connected to both Omega's past and Valgeness, the Meteokaiju who possesses a black Meteo. Zovaras also has a powerful ability to control other kaiju. To save Valgeness, Sorato and Kosei team up with Ayumu and Sayuki. The four of them launch a desperate mission to stop Zovaras, who wants to destroy Omega and conquer Earth—and they even bring the NDF into the fight.
