Gai Kurenai (クレナイ・ガイ Kurenai Gai?) is the human disguise used by Ultraman Orb after he arrived on Earth. Gai has wandered around the Earth for a long time on a mission to stop Jugglus Juggler from resurrecting the King Demon Beasts, for at least a hundred years. He uses the Orb Ring to transform by combining and using the powers of previous Ultramen.


  • Kurenai (クレナイ?紅): Is the Kunyomi for crimson/vermilion.
  • Gai (ガイ?涯): Is the Kan'on for Shore/Horizon

Following these translations, his name literally means vermilion horizon, a possible reference to his disguise as a wanderer.


When in contact with other beings, Gai always maintains good tone and shown to be forward looking. He always introduces himself to them by telling them his name during his first contact with them. He is also kind-hearted as he always saves other people from danger and helps them when needed.

Gai's one weakness is that he can't leave someone to suffer on their own. When he though Natasha Romanová was dead, he felt such extreme guilt that he sealed away Orb Origin. However, he managed to overcome this weakness thanks to Naomi Yumeno, and he regained his confidence in Orb Origin ever since.


Ultraman Orb THE ORIGIN SAGAEdit

Not much is known about Gai's past, but he was known to have climbed to the Warrior's Peak on Planet O-50 with Jugglus Juggler. They both reached out to the ring of light, but Juggler was rejected and Gai was granted the Orbcalibur, which changed him into Ultraman Orb as Origin The First whenever he would need to. He and Juggler used the Orbcalibur to get off Planet O-50 and travel to Planet Rurin, where Gai encountered a child whose parents had been victims of a Bezelb's Kugutsu and later died. He transformed into Orb for the first time, though smaller than regular Ultras, to do battle with the undersized Bezelb, but couldn't yet fight properly as Orb and was unable to use his beam correctly and thus lost quickly when the Bezelb fought back. Gai and Juggler stayed on the planet for a while to comfort the child and after scouting around, he found a few people, but the Bezelb returned. This time, Gai took Juggler's advice. He killed the Bezelb by sliding under it and firing the Origium Ray.

Later, he came across a Bemstar infected with the Kugutsu. This would mark the first time he ever transformed into his standard 50m size. After getting his Origium Ray absorbed into the monster's gorge, Orb was attacked by the monster and lost his second battle, and Gai was defeated. The two warriors left the planet.

When Gai and Juggler were flying through space via the Orbcalibur, they encountered the Bemstar again, but this time it was attempting to suck in a spaceship piloted by Micott and Ricca. He transforms into Orb again and after nearly being defeated again, he had the idea of letting himself be absorbed, only to burst through Bemstar, killing it.

He and Juggler joined the two and headed toward Planet Zain in order to stop Dr. Psychi, while waiting to get to his destination, he and Juggler had their first swordfight in the ship, where Juggler easily defeated Gai with his Snake Hearted Way. After a short rest, they ran into more Bezelb just outside Planet Zain, which caused Gai to transform and crush them all simply by flying through. When he landed on the dark planet, he was overwhelmed by a few larger Bezelb and a Kugutsu Birdon. Just when he was about to lose, Ultraman Dyna appeared and helped him out and they managed to hold off their foes.

In their human forms, Gai met with Shin Asuka, who agreed to help him go to the big tower where Psychi was.

Ultraman OrbEdit

Gai chilling

Gai outside the SSP HQ

A hundred and eight years before the events of the series, Gai met a woman named Natasha in Rusalka, whom he came to care for deeply. However when the King Demon-beast, Maga-Zetton appeared, Gai transformed and fought the kaiju. Due to Maga-Zetton unleashing a Maga Light Ball and injuring Natasha, Gai unleashed the full power of his Orbcalibur, but the resulting explosion seemingly robbed Natasha of her life and she was nowhere to be found. In his grief, he sealed away his true form, and thus had to rely on the power of other Ultra Heroes through Fusion Up to fight evil.[2]

In modern times, Gai saved Naomi and her friends from Maga-Basser and fought as Spacium Zeperion and defeated Maga-Basser. In all the confusion Gai lost his Orbnica, but Naomi found and returned it to him. He thanked Naomi for returning back his Orbnica and continued on his way, stating to the SSP that he was sure they would meet again someday.

During these times, he transforms into Orb to fight against the King Demon Beasts and had also fought directly with Jugglus Juggler, showing the rivalry between both men. He also battled monsters sent by the Planet Invasion Union and other wild Kaiju.

After defeating Maga-Pandon, Gai thought that he had stopped Juggler from resurrecting Maga-Orochi. However during a confrontation against Juggler, Gai's rival revealed his plan of resurrecting Maga-Orochi by collecting their Kajiu Cards instead of using their physical forms. Juggler then taunted Gai for not showing his true power. Gai then witnessed the "death" of Juggler and defeated Black King.

During a fake date with Naomi and her mother, Juggler was revealed to be still alive, and took Gai aside to further explain his plan ro revive Maga-Orochi, but was interrupted by Naomi's mother. Juggler still managed to show Gai the Kaiju cards of the King Demon Beasts he defeated, and revealed that Belial's Ultra Fusion card was now in his possession. Princess Tamayura's spirit then appeared as a giant astral projection, to tell Gai a calamity was approaching, before disappearing.

The next day, Gai went to the forbidden forest to confront Juggler, but the demon was able to revive Maga Orochi. Gai transformed into Orb in all his forms at the time, but was defeated by Maga-Orochi. Juggler later confiscated the Ultra Fusion card holder from Gai.

Thanks to SSP, Tamayura's grave was restored and her spirit emerged from a plant to give Gai Zoffy and Ultraman Belial's Ultra Fusion Cards, telling him that the darkness and light combined would give him great power. With the new Fusion Up, Thunder Breaster, Ultraman Orb managed to brutally finish off Maga-Orochi.

With Maga-Orochi defeated, his mission was finished, or so he thought. Gai once again had to transform into Ultraman Orb when the Civil Judge Mentor from another dimension Galactron appeared, who abducted Naomi and made her a host. Ultraman Orb once again had to use Thunder Breaster when Spacium Zeperion and Hurricane Slash did not work on the robot, but he had to pay a heavy price when Naomi had to be hospitalised because of the Zedcium Ray destroying Galactron while she was still inside it. Gai couldn't forgive himself and wondered if he had the strength to be able to control Belial's power of darkness.

Gai returned to Rusalka after 108 years and remembered his last moments with Natasha, where he was interupted when Juggler showed up once again and the two had another fight. Juggler then revealed that he was keeping the severed tail of Maga-Orochi and used it in a fusion of Zetton and Pandon to form the mighty Zeppandon, which Orb could not keep up with. After using up his energy, he lay down under a tree where he had a dream about Natasha, who gave him a blank Ultra Fusion Card and suddenly changed into Naomi, telling him that she believes in him. When Gai reawakened, the blank card was in his hand and he went back to Naomi in the hospital, only to show up just in time to save her from Juggler's katana and leave.

After rescued by Gai, Naomi said that despite Orb injured her during destroy Galactron but if don't has Orb, she can't alive and stand here and she said she still wants to help Orb even through the world against him. It revealed that Naomi is Natasha's descendant as she said her ancestor was born on Rusalka and she left a amulet (a doll), which made Gai surprises and he decide to open it and finds a picture of himself with Natasha. When Juggler showed up again with the form Zeppandon, Gai transforms to Thunder Breaster and fight, he loses control himself again and destroys many high-tension poles, which make Orb attacked by many VTL's fighters, his allies. However, an unexpected thing happended: When Zeppandon tried to kill Orb by Head Beam, Gai (as Orb) retained control of his rationality and shielded the entire SSP team with his body. Later, Naomi sang the song Gai usually played on his Orbnica, Gai was reminded to trust the extent of his own powers and the blank card given to Gai earlier by Natasha changed into the Orb Origin card, allowing Gai to gain access to his original form Orb Origin. Scanning the card into the Orb Ring to tap into his true power, the Orb Calibur revealed itself in a gleam of bright light from the tail of Zeppandon. Spinning the roulette and pressing the button on the handle, Gai transformed into his original, true form for the first time in 108 years in a mix of red, blue, yellow and green light. And Gai (as Orb) introduces himself again as "Ultraman Orb" in the Orb Origin form, which makes Naomi remembered that he was the giant of light in her dream. Threatened by the knowledge of Orb Origin form's power, Juggler controlled Zeppandon to fire at him once more, but Orb walked past them and slashed at the monster with his sword. Orb Origin then activated the earth power of the Orbcalibur with the move 'Ground Calibur', unleashing a yellow shockwave that smashed through the energy shields of the monster from two directions and dealing critical damage to Zeppandon. Juggler newest creation finally met its end as Gai scanned the Orbcalibur into his Orb Ring and summoned the combined power of all 4 elements (Fire, Water, Earth, and Wind). Orb Origin conjured a big ring of iridescent light in the sky and launched an immense beam of energy using his Orb Supreme Calibur attack. The very same beam that destroyed Maga-Zetton a century ago blasted Zeppandon head-on and annihilated the monstrosity in an epic explosion. Juggler ended up being critically injured and seemingly losing his Dark Ring for good, leaving him extremely furious.

After regaining back his original powers, Gai still uses his fusion up forms against foes and changes to Orb Origin when the situation calls for it.

Soon after, Juggler and Gai decide settle their score in their gigantic form. When Gai uses Thunder Breaster, Juggler beats him and taunts him. Gai then uses his Orb Origin Form, however, when Juggler slashes off his Orb Flame Calibur attack, Juggler continuously uses his new technique on Orb, knocking Gai unconscious. When Juggler was about to kill the SSP ,Gai stands up and beats Juggler with his full strength and finished him with the Orb Supreme Calibur after that. Gai then meets Naomi and the others after the fight.

When Naomi wakes up in the SSP office and tells Gai about the dream she had, Gai assures her that due to the hot weather, it is normal to have such dreams. Gai later meets Juggler and noted that the revival of Magata no Orochi is coming. Thus, when Magata no Orochi appears, Gai transforms into his Thunder Breaster form to try and end Magata no Orochi but to no avail. Even his Orb Origin form was useless against it. Gai then reappears in a destroyed building area, weakened, Naomi spotted him and tries to help him but Juggler appears to taunt Gai and slaying Naomi in front of his eyes.

In the final episods, Gai then confronted Juggler whom held Naomi as hostage. Gai and Juggler then have a talk about the Earth's future whom Gai states that eternal love will continue to exist as Juggler taunts him about it. When Naomi motivated Juggler to slay her, a Z-VTOL plane crashed as Gai tries to rescue her. Naomi was resuced by Juggler instead and Gai tells Juggler that there is still light in him and asked whether he is the one who rescued Natasha as Juggler reveals the truth. Gai then slaps Juggler and embrace him by hugging him. After that, he went off to fight Magata no Orochi. When Gai (as Orb) was about to be defeated by Magata no Orochi, Juggler appears and assisted Orb. When its weak point was revealed, the two tried their best to kill it, but when Juggler got binded by Magata no Orochi's tentacles, he told Gai, or rather Ultraman Orb, to attack and Magata no Orochi was finished off with the Ultimate Supreme Calibur. He then leaves Naomi and the SSP, swearing they will meet again.
