2="The faith to believe in myself...It becomes power. This is who I really am!"

- Gai unlocking Orb Origin, The Holy Sword, Restored

Gai Kurenai (クレナイ・ガイ) is the human alter-ego of 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. He uses the Orb Ring to transform by combining and using the powers of previous Ultramen. He also uses the Orbcalibur to transform to his original Ultra Form.

Etymology

 * Kurenai (クレナイ): Is the Kunyomi for crimson/vermilion.
 * Gai (ガイ): 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.

Personality
When in contact with other beings, Gai always maintains a good tone and is 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 thought 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 SAGA
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.

After the battle, Gai met with Ultraman Dyna's human host, Shin Asuka, who agreed to help him go to the big tower where Psychi was. At the tower, he saved Micca and Ricoott as well as Juggler who, got possessed by Kugutsu via Shinra's seed of the Tree of Life. Gai and the rest left the planet while going to Planet Kanon at a slower rate due to Psychi's sabotage. TBA

Gai then reunites with Juggler, whom was the bodyguard of Alien Nackle Ramon Brothers. Before they fight, Juggler claimed the wind element jewel from the alien he killed. Gai and Juggler fought just as Gai about to deliver the finishing blow, Gai cannot bring himself to do that.

Decided to dress up as a member of that religion to investigate but Dodongo appears as Gai became Orb and defeated it. Soon later, Maga-Tanothor was freed as Gai transformed into Orb and defeated it after a tough battle, obtained Ultraman Tiga's card after the battle. Gai then left Ishtal years later after meeting Dana, whom was dying.

Chapter 5 " From Rulsaka of Love " arc
In 1908, Gai arrived in Rulsaka and then fought Kingsaurus II in Lake Baikal as Orb. Gai lost his memories after his fight with C.O.V., reverting back to Gai. When he was resting on a tree, he met a woman named Natasha in Rusalka, whom he came to care for deeply, but Gai does not remember what happened to him before that. But, during the rampage of Pris-Ma, after Gai defeated it, he regains his memories. Gai was still recovering from his injuries, 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. Gai later journeyed to North Arctic and fought Peguila, later he when to Japan on board a train there while Juggler awakened Maga-Bassar.

Ultraman Orb
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 to 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 interrupted 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 recounted to Gai despite Orb caused her to be critically injured, she believed Orb was doing the right thing. Also recounting to Gai about her great great-grandmother and sang the song that Gai usually plays, causing Gai to open the pendant and reveal his picture with Natasha. Gai was saddened by the truth as Natasha survived the explosion and proceeds to hug and thank Naomi. Gai then entrusted his Orbnica and tasked Naomi to save Orb and then transformed into his Thunder Breaster to fight Zeppandon the second time. Even after being targeted by the VTL and blasted by Zeppandon, Gai/Orb shielded the SSP and restores his reputation. After Naomi sang the song which Gai tasked her to do before, Gai summoned his courage and transformed back to his Original form, trusting the extent of his powers. Gai/Orb introduced himself and finished Zeppandon with Orb Supreme Calibur after a short assault. After the battle, he reunites with Naomi and assured Natasha that he will save the Earth.

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.

"Darkness isn't eternal. The only thing that's truly eternal is love. It's love that keeps the universe turning. It's a light of hope that shines in the depth of that darkness."

- Gai Kurenai, The Wandering Sun

In the final episodes, 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 rescued 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.

Transformation
{{#tag:tabber| Fusion Up= Gai first scans a pair of Ultra Fusion Cards in the Orb Ring, creating a projection of its two corresponding Ultra Warriors as the screen facing the respective angle of their faces. Afterwards, he performs a specific movement and raises the Orb Ring up which causes his body to transform into Ultraman Orb with his entire body being covered in a luminous silhouette. The Ultra projections shine the same color as their respective Ultra Fusion Card's attribute and combine with Orb to create their corresponding form. This caused his silhouette to evaporate and unveiled its corresponding form. After the rising sequence, Orb delivers a specific pre-battle catchphrase just before descending into the fight.

Despite the long transformation time, this was done in a time freezing sequence as in episode 5, Orb switches from Spacium Zeperion to Hurricane Slash in a moment in mid-air whereas Gai's sequence was supposedly longer than the intended time.{{Storylink|A Heart That Won't Flee}} If at any point the transformation is interrupted from within, the time freezing effect is lost.{{Storylink|The Dark King's Blessing}}

{{#tag:tabber| Spacium Zeperion= {{Quote|Ultraman! Tiga! I'm borrowing the power of your lights!|Activation announcement for Spacium Zeperion}}

After scanning both cards, Gai simply raises the Orb Ring up similar to both Ultraman's Beta Capsule and Tiga's Spark Lens. During the rise sequence, the background first appears to resemble that of the opening sequence from Ultraman's TV series (a green twisted spiral followed by a red explosion) before changing to Tiga's rise sequence for Orb to appear. Flashes of light occur in the background similar to Ultraman and Tiga's rise scenes.

In the final episode, Gai while running transforms in a real time sequence as projections of Ultraman and Tiga fly alongside him before he transforms into Orb Origin and the former two combine with him to form Spacium Zeperion.{{Storylink|The Wandering Sun}}
