</tabber>
, formerly known simply as , is the human alter-ego of Ultraman Orb, and the main protagonist of the Ultraman Orb TV series, and the literature Ultraman Orb Chronicle. Gai has wandered around the Earth for a long time on a mission to stop Jugglus Juggler from resurrecting the Lord Monsters. He uses the Orb Ring to transform by combining and using the powers of previous Ultramen. He also uses the Orb Calibur to transform to Orb Origin.
==Conception==
===Etymology===
*: Is the Kunyomi for crimson/vermilion.
*: 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.
Gai came up with the name "Kurenai" at the end of one of his adventures, where he saw the deep red colors of the sunset and felt that it was a beautiful sight.
==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 is unable to 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 and also led him to believe that his presence would bring trouble into everyone's lives. However, he managed to overcome this weakness thanks to Naomi's help, and he regained his confidence in Orb Origin ever since.
Gai and Juggler shared a complex past. While the two would compete whenever given the chance, Gai and Juggler were once best friends who honored each other as warriors. Sadly, from the very day the light of Orb chose him over Juggler, their relationships gradually deteriorated to the point where their originally friendly rivalry turned into an outright feud. Even so, Gai is unable to bring himself to take Juggler's life due to their past friendship, and was thankful to him upon figuring out Juggler saved Natasha in the past. Nevertheless, he keeps an eye on his rival, aware that while he is a dependable ally, Juggler could also be his worst enemy.
Gai treats his senior Ultra Warriors with the utmost respect and sees it as an honor to fight alongside them whenever given the chance. In fact, whenever he utilizes Ultra Fusion Cards out of their lights, he would cry out to borrow their powers although he was initially reluctant to use Ultraman Belial's card due to his reputation.
==History==
===Ultraman Orb Chronicle===
====Chapter 1: 'Tree of Life' Arc====
Not much is known about Gai's past, but he was known to have climbed to the Crusader'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 Orb Calibur, which changed him into Ultraman Orb as Origin The First whenever he would need to. He and Juggler used the Orb Calibur 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 Beam.
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 Beam 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 Orb Calibur, 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 sword fight 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 Ricca and Micott 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. They eventually arrived, but Psychi already started his attack. Transforming into Orb once more, he and Dyna held off the attacking Kaiju while Juggler retrieved a seed from the Tree of Life, which he then passed to Orb, who used it to purify the War Deity who had been infected with Kugutsu. However, after Micott's death, Juggler decided to cut down the Tree of Life, deeming it an enemy, while also striking down the War Deity in the process. Psychi left after the tree disappeared, and Gai went to reprimand Juggler, who rejected being his partner from then on.
Later, Gai went to Earth with Ricca after finding out that the Tree of Life was there. There, he met with Shohei Moriwaki, Yui Nishioka and Gamu Takayama. After fighting off several more Bezelb along with Ultraman Gaia, Gai explained to Gamu about Juggler, who had assisted him earlier. Gamu compares their relationship to his own with Hiroya Fujimiya, who then arrives. Amate soon arrives on Earth, and Gai decides to protect her. He then finds out that Psychi was hiding on the moon. Attacking the Bezelb outside his base, Gai gets into the spaceship and talks with Psychi, but is trapped. Juggler comes to strike Psychi down, but he finds out that it is but a hologram, and saves Gai, going back to Earth together.
Gai starts to wonder whether Psychi was right all along, which makes him defend the Queen Bezelb while it was under attack by the military. Eventually, he finds out that the Queen tricked the War Deity into transforming to infect her with Kugutsu, but just as she was about to be stung, Gai transformed into Orb and took the hit instead. However, the War Deity is eventually infected with the Queen's Kugutsu, which would cause her to explode and rob the entire universe of its intelligence. Orb then rampaged under the influence of the poison, until Juggler arrived to convince him to turn back into Gai, so that he could give him a seed from the Tree of Life and purify him.
Juggler strikes down the Queen Bezelb and, cornered, Psychi merges with her to become Psyqueen. Orb, Gamu, Fujimiya, as well as Asuka and Musashi transform into their respective Ultras to defend the Tree of Life, contain the War Deity, and to battle Psyqueen. The War Deity was eventually purified by the efforts of Shohei, Yui, Orb and Cosmos, and the Ultras dealt their respective opponents. They prepared to finish off Psyqueen, but Orb flew in to save Psychi, just before the Queen Bezelb was destroyed in an explosion. Gai assures Psychi that the Tree of Life was really the countermeasure to the Kugutsu, instead of the other way around. He later says goodbye to his predecessors and goes back to Planet O-50.
Atop the Crusader's Peak, he sees a vision of Juggler, which fades away. The Ring of Light emerges from the Orb Calibur to give him his next mission, and then transforms him into Orb. Origin the First is upgraded into Orb Origin, and Orb flies away, embarking on his next quest.

=====Episode 6-0: Overture=====
Gai later journeyed to North Arctic and fought Peguila, and later went to Japan on board a freezer truck while Juggler awakened Maga-Basser.
=====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 Lord Monsters 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 Lord Monsters 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 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 Breastar, 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 Breastar 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 hospitalized because of the Zettcium Beam 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 Breastar 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 to settle their score in their gigantic form. When Gai uses Thunder Breastar, 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 Magatano-Orochi is coming. Thus, when Magatano-Orochi appears, Gai transforms into his Thunder Breastar form to try and end Magatano-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 episodes, Gai then confronted Juggler who held Naomi 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 Magatano-Orochi. When Gai (as Orb) was about to be defeated by Magatano-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 Magatano-Orochi's tentacles, he told Gai, or rather Ultraman Orb, to attack and Magatano-Orochi was finished off with the Ultimate Supreme Calibur. He then leaves Naomi and the SSP, swearing they will meet again.
====Chapter 7: 'Space Witch Mulnau's Counterattack, Sadis' Return'====
A few months later, Gai returned from Hawaii after defeating Galactron with the aid of Ultraman Zero to Japan by saving the SSP from the Dark Alien Army and found out about Ultraman X's X Devizer. X told him about Daichi Oozora, who had been captured by mysterious figures in a spaceship that looked like a house. Upon arriving there, Gai was greeted by Juggler, before being trapped in a dimensional distortion via the Bullton Kaiju Card. He met an old enemy, Sadis. Gai transformed into Orb and fought him, but with Alien Hipporit Callisto and Alien Temperor Batista coming in as reinforcements, Gai was defeated and captured. He was brought to another one of his old enemies, Mulnau, who revealed that she obtained the Dark Ring and had captured Ultraman Ginga and Ultraman Victory, having turned them into crystals. Gai then watched as Mulanu summoned Darebolic, who wreaked havoc on the city and threatened to turn the entire planet into a crystal. Luckily, Juggler switched sides and freed Gai and the SSP were around to distract the others, and they had also freed Daichi.
Gai and Daichi transformed and fought a losing battle against Darebolic and Sadis. Just before Gai was about to be crystallized, X got in the way and took the hit for him, but Orb was knocked out by Sadis and reverted back into Gai. Seeing Gai among the rubble, Jetta and Shin find out that he was Orb all along. Through the SSP's words, Gai is granted the Ultra Fusion Cards of Ginga, Victory and X, from the respective Ultras themselves, which he used to transform into Orb Trinity. When Gai was getting beate, Juggler decided to help him by transforming into Zeppandon, but was ineffective in battle and was beaten with relative ease. As the battle raged on, the other three Ultras were eventually freed after Juggler tosses the Dark Ring into a wormhole. However, the four Ultras' effort were still not enough and Gai was still getting defeated by Darebolic, until Dan Moroboshi arrives and transforms into Ultraseven. Firing his Trinitium Ray, which was subsequently reflected by Darebolic, it bounced off to Mulnau's ship and caused it to crash by accident.
The five Ultras are finally able to defeat all their opponents. After the other four depart, Gai visits Mulanu in her dying moments, having one last talk with her before she passes away. Gai then says goodbye to the SSP and Shibukawa before leaving on his next adventure. On the way, Zero contacts him again, asking him to help fight against Desastro.

He helps them defeat the aliens harassing them and takes a drink. Later, while the rest are getting info from Alien Jaki Arlon, Gai tells Riku about his past experiences with Galactron and that Ultramen aren't perfect. Galactron MK2 suddenly invades, so Gai and Riku transform together to fight it. The two fought a difficult battle and then they were joined by Ultraman Zero. When Geed was shot by Galactron MK2 and sent to cyberspace, Orb used the power of X's Gomora Armor to enter that cyberspace to rescue Geed. Galactron MK2 targeted Geed with a barrage of beams, but Orb and Zero stand in the way of the incoming attack and seemingly died. This causes Geed to be furious, and he finished off Galactron MK2.

==Trivia==
*Gai/Ultraman Orb's concept as a traveler is based on Dan Moroboshi/Ultraseven. This is acknowledged by Takao Nakano, one of the writers of Ultraman Orb. Kiyotaka Taguchi also stated that Gai's role was an act as if Dan had never met the UG team.
*His given name, and the fact that he is played by Hideo Ishiguro, is one kana away from his previous role as Kai in Kamen Rider Den-O.
*Gai has a great love of hot spring bathing as shown in the episode Monstrous Waters, where he calls it 'Earth's greatest luxury'. He also takes issue with anyone with poor hot spring etiquette.
*His name is simply written as 'Gai' in the opening sequence of Ultraman Orb THE ORIGIN SAGA.
*As revealed in one of the manuscripts, Gai's Orbnica was meant to be a pan flute. Ultraman Orb Super Complete Works pages 111 and 112: Special Compilation: 'Ultraman Orb Year 1908 Events' Second Manuscript
*Throughout Ultraman Geed The Movie, Gai as Ultraman Orb is seen wearing his casual outfit, instead of the black spandex suit in previous appearances.
