"Look, the Earth is round. I'm sure we will run into each other again eventually. See ya."

―Gai Kurenai, The Sunset Wanderer

"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 Kurenai Gai), formerly known simply as Gai (ガイ), 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 Orbcalibur to transform to Orb Origin.



  • 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.

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.


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.


Ultraman Orb Chronicle

Chapter 1: 'Tree of Life' Arc

Main article: 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 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 God 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 God 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 God 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 God 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 God, and to battle Psyqueen. The War God 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 Warrior's Peak, he sees a vision of Juggler, which fades away. The Ring of Light emerges from the Orbcalibur 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.

At first, Scudder refuses to trust Gai but after they encounter the Three-meter Aliens (3メートルの宇宙人 San Mētoru no Uchūjin), he starts to trust the wanderer.

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
Gai chilling

Gai outside the SSP HQ

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 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 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 Magata no Orochi is coming. Thus, when Magata no Orochi appears, Gai transforms into his Thunder Breastar 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 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 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.

Chapter 7: 'Space Witch Mulnau's Counterattack, Sadeath's Return'

Main article: Ultraman Orb The Movie: Let Me Borrow the Power of Bonds!

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, Sadeath. 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 Sadeath. 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 Sadeath 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.

Ultraman Geed The Movie: Connect the Wishes!

Gai reunite with Juggler

Gai reunites with Juggler.

Gai first appears in an alien town during a fight between a whole lot of aliens, Juggler, Riku Asakura, and his friends, while playing the Orbnica. 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.

Later, Orb returns, somehow having survived the previous encounter, to help Juggler and Gukuru Shisa face off against the Galactron Army.

Ultraman Orb: The Chronicle

Gai talks about his adventures as Orb in this series. In the last episode, he is seen first on Planet O-50, talking to the Ring of Light atop Warrior's Peak, before appearing in R/B's world, wishing the brothers good luck and setting off for ventures beyond.

Ultraman Taiga The Movie: New Generation Climax

Gai travelled to Taiga's universe alongside the other New Generation Heroes to protect Hiroyuki Kudo from being targeted. He teamed up with Kana Sasaki when the latter went undercover into the Villain Guild base.


Gai scans the Orb Origin card to bring forth the Orbcalibur and spin its wheel. Then he raises the sword upwards and presses the trigger, causing all four element symbols on the sword to shine and create an energy orb from which Orb Origin rises.

In Ultraman Orb: The Chronicle's first episode, Gai is seen transforming into Orb Origin in real time only using the Orbcalibur without having to brandish the Orb Ring or the Orb Origin Ultra Fusion Card, similar to his rise as Origin The First.

Gai presses the trigger of the Orbcalibur and raises it towards the air. Origin The First soon appears from a red background and approaches the screen while the background changes colors and rings of light appear.

In the final episode of THE ORIGIN SAGA, Gai shouted Orb's name before he transforms, doing so in synchronization with his seniors.

The transformation can also be activated involuntarily by Gai, being triggered by the Orbcalibur itself, in real time. It places a ring of light on Gai's chest (which becomes Orb's Color Timer), and he grows to larger size in a pillar of flowing light, becoming Ultraman Orb. This only happens in THE ORIGIN SAGA, during the first and last time Gai transforms in the series, and once in Ultraman Orb in a flashback Juggler had.

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.A Heart That Won't Flee If at any point the transformation is interrupted from within, the time freezing effect is lost.The Dark King's Blessing

"Sir Ultraman! Sir Tiga! Let me borrow 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 a bluish background similar to the opening of Tiga's TV series and then 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 runs and 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.The Wandering Sun

"Sir Taro! Sir Mebius! Help me bring the heat!"

―Activation announcement for Burnmite

After scanning both cards, Gai spreads his arms backwards similar to Taro's transformation sequence and twists his body backwards similar to Mebius' transformation sequence before raising the Orb Ring up. During the rise sequence, the background first appears to resemble that of the opening sequence from Ultraman Taro's TV series (plain black with a flash of light) before changing to Mebius' rise background for Orb to appear. As he moves forward, silver loops from Taro's rise also appear.

"Sir Jack! Sir Zero! Give me something with an edge!"

―Activation announcement for Hurricane Slash

After scanning both cards, Gai raises his right hand similar to Jack's transformation sequence before he lowers it for his left arm to approach closer to his face similar to Zero's Ultra Zero Eye and then raises the Orb Ring up. During the rise sequence, the background first appears as Jack's rise sequence before changing to Zero's rise sequence for Orb to appear. As he moves closer, a background similar to Shining Zero's rise takes place.

"Sir Zoffy! (Gai roars in rage)"

―Initial activation announcement for Thunder Breastar

In his first transformation, Gai is incapable of utilizing Belial's power but once given approval, Belial introduced himself by having a tear opening up to reveal his front face, laughing towards the screen. After scanning both cards, Gai roars in rage while vigorously flailing his arms forward similar to Kaiser Belial's usage of the Kaiser Belial Claws before he raises the Orb Ring.

"Sir Zoffy! Sir Belial! Let me borrow the power of light and darkness!"

―Activation announcement for Thunder Breastar

"Sir Belial! Sir Zoffy! Let me borrow the power of darkness and light!"

―First standard activation announcement for Thunder Breastar

After scanning both cards, Gai slowly swings his left and right arm before twisting his body backwards and then raising the Orb Ring.

During the rise sequence, the background first appears as the Space Prison covered in a reddish-like aura (the same from Alien Rayblood's assimilation with Belial) before changing to blue (based on the opening sequence from Zoffy's feature movie) for Orb to appear where it changes once again to dark red (based on Belial's aura when forming Belyudra). As he moves closer, the background briefly changes to an orange background similar to Zoffy's rising scene in the final episode of Ultraman Mebius before changing to emerald with multiple colors based on the colors of Arch Belial.

"Sir Ginga! Sir X! Let me borrow the power to electrify my enemies!"

―Activation announcement for Lighting Attacker

When scanning both cards, Ginga and X faces towards the screen besides Gai as their upper chest are also shown. After scanning both cards, Gai swings his arms in a circular fashion similar to Ginga's transformation sequence and throws his arms back to his left similar to X's transformation sequence and then raises the Orb Ring up. His silhouette does not evaporate and the scene skips to his rise. During the rise sequence, Orb rises with his arms crossed in front of his chest like X does, rising in a galaxy similar to Ginga's rise before changing to cyberspace and releasing an "X" construct while having a spiral galaxy behind it. He changes his arm positions as the background changes yet again to resemble X's, while yellow lightning bolts come off him throughout the rise scene.

"Sir Ginga! Sir X! Let me borrow the possibility of the future!"

―Alternate activation announcement for Lightning Attacker

Ultraman X bestows Orb his own Ultra Fusion Card and then gets Ultraman Ginga's Ultra Fusion Card from the audience. After scanning the cards, the transformation scene unveils Orb in Spacium Zeperion (instead of Gai himself or Orb Origin's silhouette), placing his arms on his chest in a cross position before lifting up his left hand. After that, the scene changes to reminisce X's rise background where Lightning Attacker approaches the screen.

"Sir Seven! Sir Zero! Let me borrow the power of father and son!"

―Activation announcement for Emerium Slugger

Instead of only their heads, Seven and Zero's entire body (save their lower waist) are shown in a different angle. Gai performs Leo/Zero's Space Martial Arts stance before he puts his arm in a cross and brings them backwards in a similar manner to Seven's rise. Once he raises the Orb Ring, his silhouette as Orb combines with Seven and Zero as it evaporates and a pair of Sluggers circulate his body and attach themselves to his head. During his rising scene, a blank spatial background appears where Orb rises from Seven's transformation spark as it changes into the opening of his series background and finally changes into those of Zero's rising scene.

"Sir Ginga! Sir Victory! Sir X! Let me borrow the power of your three lights! Orb Trinity!"

―Activation announcement for Orb Trinity

Unlike in Fusion Ups, his card components first circulate around Gai before he takes and scans them. After pressing the Orb Ring's trigger, the Orb Slasher materializes where he proceed to slide his finger downwards, before spinning his hands in circle and raises the weapon.

The summoned Ultra projections combine with Orb's silhouette but instead of evaporating, it absorbs nearby matter to unveil himself. Orb Trinity rises in a background of a galaxy and cyberspace, while crystal shards are dispersed in the background, before switching his arm position as he moves closer.

  • 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.[3]
  • Throughout Ultraman Geed The Movie, Gai as Ultraman Orb is seen wearing his casual outfit, instead of the black spandex suit in previous appearances.
