List of Ultraman Orb: The Origin Saga episodes

After being chosen as the Warrior of Light, Gai and Juggler embark on their first mission by entering Orion Nebula to stop Psychi and his army of Bezelves. Gai and Juggler made their stop on Planet Rurin, where they defend Morcus from his enslaved parents and the Bezelve that controlled them. When transforming into Ultraman Orb for the first time, Gai has troubles in controlling his power before he can properly finish the monster in their second fight.

Psychi threatens the Kanon natives to surrender their queen Amate or else he would launch a full-scale assault on their tree. Raigo of the Kanon Defense Army asserted Amate to become the War Deity and lead their army in a raid to Psychi's base. Wanting a peaceful solution, Amate sent Shinra on an expedition to Planet Zain, where Psychi greeted him and demonstrated the Kugutsu utilized by Bezelves, enslaving their victims and feed on their strength to become stronger. Through his connection to the Queen Bezelve, he can also manipulate the Bezelves and their victims.

Failing to threaten Shinra after he planted bombs around the base, Psychi can only ask for a drop of Amate's blood before the former departed. The syringe was kept by Amate, who agrees with Psychi's plan but Shinra refused out of safety. At night, while Amate reminiscing how the previous queen (her mother) lost her life after using the War Deity to fight Gargorgon, Shinra intruded her room until he was chased away by Micott and Ricca, with the soldiers believe that he is going to infect the queen with Psychi's Kugutsu. With Shinra sent to a remote planet for exile, he escaped via an escape pod, forcing Micott and Ricca to chase him and pursue the truth.

After erecting a grave for Morcus' parents, Gai and Juggler decided to bring the boy to a nearby village for adoption. They discovered that an infected Bemstar stationing there as Gai left Morcus to a villager and transforms to fight the monster. With Bemstar absorbing the attacks, it escaped to space and Gai and Juggler chase the monster, where it proceed to consume the Suzark piloted by Micott and Ricca. Gai left Juggler to save the ship and its pilot while he fought against Bemstar as Ultraman Orb.

After destroying the infected Bemstar, Gai deduced that the Bezelves are heavily related with Kanon's crisis, thus joining the Kanon Royal Guards on their journey to Planet Zain. Before they can reach the planet, a swarm of Bezelves attack their ship and Gai transforms to fight them, with an infected Birdon entered the battle.

On Earth, once the research team connects the seal fragment, they deduced that the illustration is in fact the Yggdrasil tree. Shohei suffers a backlash from the seed that sent him in coma and sketches Kanon's Tree of Life once he awakened as his mind is being dominated by memories of Amate.

After Orb and Dyna finished the Bezelves, they introduced each others in their human identities as Gai still ponders on the reason he obtained Orb's power while Asuka gives him a handful of advice. Leaving the Bezelves to Juggler, Micott and Ricca found their captain imprisoned. When Juggler gets infected by the Kugutsu, Shinra cures him by using the Tree of Life's seed given by Amate before.^[5] After Psychi escaped, the party tries to chase him but the former sabotaged their ship beforehand, preventing hyperdrive functions. Shinra reveals how the commotion happened: Raigo had set up an impostor to attack Amate while he was quickly banished, allowing the latter to force Amate into the battle as the War Deity. When Shinra tries to return to the planet with said pod, he was kidnapped by Psychi to ensure the latter's plan would not be interrupted, while slipping out the Tree of Life's seed as the cure of Kugutsu. Not wanting Gai to waste his energy to chase Psychi, Asuka orders Musashi/Ultraman Cosmos to do the work.

Psychi's ship arrived earlier and threatens to attack Kanon by morning should they refuse to surrender Amate. Raigo and his troops try to find Amate but she escaped.

Musashi met Amate and discuss over her wish to find a peaceful solution. Coerced by her people's suffering from the Bezelve's attack, Amate finally accept her fate and transforms to defend her castle.^[6]

After a swordsmanship training with Juggler, Gai was noted by many that he held back his true potential until Asuka gave him an advice. When Amate transformed into the War Deity, Gai was incapable of holding back his frustration when he assumed it as his failure.

The War Deity transformed and tried her best to avoid casualties, not wanting to harm her opponents either. Seeing this, Asuka and Gai raced to Kanon as Dyna and Orb to fight the Bezelves while the War Deity establish a contact with the Queen Bezelve. Although seemingly successful, the Queen backstabbed the War Deity with Kugutsu, infecting her before Cosmos interfered and Juggler provide the Ultras with the Tree of Life's seed. After Micott was stabbed by a Bezelve, Juggler lets out a shrill scream in response to his fear.^[7]

Under a huge trauma from witnessing Micott's death, Juggler's wish for power transformed him into an armored demon and sliced down the Tree of Life after seeing it as the source of all conflict. The War Deity was forced to destroy it in order to save the citizens, therefore endangering the planet and crushed Psychi's plan. After being branded as an enemy, Juggler broke his ties with Gai and left while both Amate and the Queen Bezelve sensed another Tree of Life.^[8][a]
