Ultraman Omega: Season 1

Kosei Hoshimi, a young warehouse worker, stumbles upon a mysterious amnesiac man secretly devouring his yakisoba. When the man suddenly takes off, Kosei's pursuit lands him right in the middle of a kaiju attack tearing through the city! Witnessing Kosei's compassion for a girl in the shelter, the amnesiac resolves to shield the city from the kaiju, and a crimson light ignites within him!

The amnesiac man declared his name: Omega. Kosei brought him back to the warehouse, and they start living together. Though Omega's past remained a mystery, the two ventured into the forest, hoping to uncover the true nature of the kaiju reported on the news. It was within this forest that their path crossed with Ayumu Ichido, a biologist. Kosei introduced the amnesiac to Ayumu as Sorato. The three began working together to search for the kaiju.

A kaiju appeared at a construction site deep in the mountains. Soon after, it suddenly died, but the reason is unknown! Ayumu and her junior team member, Yuta, go to investigate in the mountains. Another kaiju of the same species appears there and chases them until they are completely lost... Then, the kaiju begins to advance toward the city with unstoppable determination. Where is it going, and why?

Mt. Kirifuri is a place with frequent reports of paranormal phenomena. Ayumu asks Sorato and Kosei to accompany her there to visit a paranormal research club studying the Brigadoon phenomenon, which they claim occurs in the mountain's thick mist. When an accidental occurrence of the phenomenon opens up another dimension, Ayumu ends up lost inside!

As Sorato and Kosei argue over a banana at breakfast, news breaks about a hibernating kaiju discovery. The two team up with Ayumu and infiltrate Kanenari Corporation, a leading Japanese company sheltering the creature. But the company's president, who advocates for kaiju protection, extends a job offer to Ayumu...!

Sorato and Kosei have been asked for a closeup exclusive! Reporter Maki is determined to get a proper close-up of the two, but her enthusiasm throws them off. After a kaiju that appeared in a hot spring town slips through their fingers, the two friends get in a big fight!

Left behind from the latest kaiju fight and frustrated by the news that Omega isn't getting public support, Kosei rushes out when he hears that Graim has appeared again. Meanwhile, Ayumu, who has joined forces with Kazuyasu Taira of the NDF, begins a plan to capture Graim, but the situation takes an unexpected turn.

Sorato regrets getting Kosei involved in his fight against the kaiju and decides to leave Taiyo Warehouse. Following his departure, as Kosei wanders around wallowing in sadness, he runs into a researcher collecting samples. They work together and this prompts Kosei to think once more about what it is that he wants to do. Meanwhile, after absorbing Dugrid, Eldeghimera has become even stronger and the NDF plans a massive operation to take it down.

During the battle with Eldeghimera, Kosei's ability to summon Rekiness is discovered by Ayumu. As Kosei and Sorato anxiously talk it over, they reflect on all the events that led to this moment, trying to figure out how to explain everything to her. When Ayumu finally arrives, a strange visitor shows up at the Taiyo Warehouse, breaking the tension in the air!

A mysterious man with a black Meteo around his neck has landed in Ohito City. Meanwhile, an unexpected visitor comes to Taiyo Warehouse. It's Sayuki Uta, the researcher Kosei met and collected samples with. It turns out that she's a genius scientist and Ayumu's mentor! But their conversation with the easygoing Sayuki Uta is cut short when the invader comes for Sorato's life!

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!

Sorato, Kosei, and Ayumu decide to join the KSCT Special Task Unit Sayuki has invited them to be a part of. While they're setting up their base of operations at Taiyo Warehouse, they suddenly receive their first assignment... investigating a kaiju that appeared at a fishing port? Sorato and the others get some new gear and set out to investigate the mysterious kaiju. Their first mission as the KSCT begins!

Using a new weapon developed by the NDF, humanity achieves its first solo victory against a kaiju! However, the kaiju, which was clearly defeated and dead, suddenly reanimates! The KSCT and the NDF coordinate a defense strategy, but the situation rapidly worsens. To discover the weakness of this "immortal" kaiju, Sorato and Sayuki fly to the permafrost of the North!

Kosei challenges Sorato to a fight as part of his battle training with Rekiness, Trigaron, and Valgeness. But their training ground deep in the mountains turns out to be the Alien Barossa Zahgon's lair and he covets their treasure... the Meteokaiju?! Zahgon captures Sorato and Kosei, then a mysterious girl named Gilda appears in front of Kosei.

The best kind of creation, where you go all out to make it awesome? Eiichi, a boy obsessed with making Tokusatsu works, stumbles upon a mysterious red crystal while taking pictures of a kaiju that suddenly appears in Ohito City. This crystal is an unknown substance that fell from space, capable of absorbing people's negative emotions and converting them into energy!

Unit Uta is dispatched to an abandoned factory to investigate mysterious gravity waves. They find a frightened, injured little kaiju with the ability to travel through time!

While Sayuki is away, a inspector who calls himself Sayuki's rival, Makoto Raionji, arrives at the KSCT headquarters! News of a mysterious bamboo shoot kaiju appearance sends Sorato and the others out to investigate. However, the overbearing Raionji rejects all of their opinions... To protect the city's peace and the pride of Team Uta, what will be the decisive action taken by Ayumu, who has been put in charge as acting leader?!
