Main characters

Takeru Tenkūji

Takeru Tenkūji (天空寺 タケル, Tenkūji Takeru) is the current heir to Daitenkū-ji who displays in an interest in historical figures after his ghost hunter father, Ryū, left him the tsuba from Miyamoto Musashi's katana, which the former wears as a necklace, and enjoys reading from a book titled Stories of the World's Greatest People (世界偉人伝, Sekai Ijinden). Wishing to follow in his father's footsteps despite being unable to see ghosts, Takeru receives a Ghost Eyecon (ゴースト眼魂, Gōsuto Aikon) on his 18th birthday, which allows him to see monstrous ghosts called Gamma before they kill him for other Eyecons. A mysterious hermit brings Takeru back to life as a ghost and grants him the ability to transform into Kamen Rider Ghost as the latter has 99 days to find 15 Eyecons based on famous historical figures to fully restore his life.

After seeing his childhood friend Makoto Fukami become the cold Kamen Rider Specter as a result of his sister Kanon's body being trapped in the Gamma World, Takeru sacrifices the opportunity to revive himself to save Kanon instead and gains the ability to enter people's memories following his first trip to the Gamma World. Along the way, Takeru discovers he disrespected Ryū for involving him in the latter's ghost hunting expeditions, but his father did so because of his potential to bring peace between the human and Gamma Worlds. Additionally, Takeru's Eyecon was supposed to contain Ryū's soul and, if he does not restore his original body within another 99 days, both Tenkūjis will disappear forever. While doing so, Takeru and his allies save the world from the Gammisers and he receives multiple wishes from the Great Eye in recognition of his good deeds. Using one to fully revive himself, Takeru returns to high school to finish his education.

In the tie-in novel Kamen Rider Ghost: Memories to the Future, Takeru marries Chloe after sacrificing the Mugen Eyecon and half of his life force with the Great Eye's help, eventually having a son named Ayumu not long after. In the near future, the lack of his Mugen Eyecon prevents him from accessing his full potential and he is absorbed by the Great Demia. However, Takeru is rescued after Ayumu dons the mantle of Ghost and kills the Great Demia without endangering Takeru's life, allowing him to reunite with his family once more.

Takeru utilizes the Ghost Driver (ゴーストドライバー, Gōsuto Doraibā) belt and one of several Eyecons to transform into Kamen Rider Ghost. While transformed, he wields the Gan Gun Saber (ガンガンセイバー, Gan Gan Seibā, Eye Gun Saber), which has several modes he can use depending on his form, can perform Omega Drive (オメガドライブ, Omega Doraibu) finishers, and possesses the Machine Ghostriker (マシンゴーストライカー, Mashin Gōsutoraikā) motorcycle, which can combine with the flying ghost ship-like Captain Ghost (キャプテンゴースト, Kyaputen Gōsuto) vehicle to form the Iguana Ghostriker (イグアナゴーストライカー, Iguana Gōsutoraikā) mecha. Without an Eyecon, he starts out in a powerless Transient (トランジェント, Toranjento) form, which serves as the base for a Hoodie Ghost summoned by an Eyecon to drape itself over him and become a more powerful Damashii (魂, "spirit or soul") form. Takeru's many forms are as follows:

• Ore Damashii (オレ魂): Takeru's default form accessed from the Ore (オレ, Me) Eyecon, which contains his soul, that grants levitation capabilities. In this form, he can wield the Gan Gun Saber in either its sword-like Blade Mode (ブレードモード, Burēdo Mōdo), which allows him to perform the Omega Break (オメガブレイク, Omega Bureiku) finisher, or its double-bladed Naginata Mode (ナギナタモード, Naginata Mōdo), which allows him to perform the Omega Stream (オメガストリーム, Omega Sutorīmu) finisher.
  • Toucon Boost Damashii (闘魂ブースト魂, Tōkon Būsuto Damashii): The evolved form of Ore Damashii accessed from the Toucon Boost (闘魂ブースト, Tōkon Būsuto, Fighting Spirit Boost) Eyecon, which is powered by Ryū's soul, that enhances preexisting Damashii forms, grants pyrokinesis, and allows Takeru to perform the Boost Omega Drive (ブーストオメガドライブ, Būsuto Omega Doraibu) finisher. In this and all subsequent forms, he wields the Sunglasseslasher (サングラスラッシャー, Sangurasurasshā), which has a Sword Mode (ソードモード, Sōdo Mōdo) for performing the (Mega) Omega Shine ((メガ) オメガシャイン, (Mega) Omega Shain) finisher and a Blaster Mode (ブラスターモード, Burasutā Mōdo) for performing the (Mega) Omega Flash ((メガ) オメガフラッシュ, (Mega) Omega Furasshu) finisher. Initially, this form served as Takeru's sole means of accessing Goemon, Ryoma, and Himiko Damashii to keep up with their enormous power until his continuous development as a Kamen Rider allowed him to access their forms with Ore Damashii. This form first appears in the non-canonical crossover film Kamen Rider × Kamen Rider Ghost & Drive: Super Movie War Genesis.
• Grateful Damashii (グレイトフル魂, Gureitofuru Damashii): Takeru's super form accessed from the Eyecon Driver G (アイコンドライバーG, Aikon Doraibā Jī) belt that allows him to utilize the powers of all 15 heroic Eyecons at once, summon their Hoodie Ghosts for combat assistance, and perform the Grateful Omega Drive (グレイトフル オメガドライブ, Gureitofuru Omega Doraibu) and (Mega) Omega Formation ((メガ) オメガフォーメーション, (Mega) Omega Fōmēshon) finishers.
• Mugen Damashii (ムゲン魂): Takeru's rainbow-themed ultimate form accessed from the Mugen (ムゲン, Infinite) Eyecon, which is powered by his friends' emotions, that allows him to perform the God Omega Drive (ゴッドオメガドライブ, Goddo Omega Doraibu) finisher on his own and the Yorokobi Stream (ヨロコビストリーム, Yorokobi Sutorīmu, Joy Stream), Tanoshii Strike (タノシーストライク, Tanoshī Sutoraiku, Fun Strike), Shinnen Impact (シンネンインパクト, Shinnen Inpakuto, Faith Impact), Isama Shoot (イサマシュート, Isama Shūto, Valiant Shoot), Ikari Slash (イカリスラッシュ, Ikari Surasshu, Anger Slash), Kanashimi Break (カナシミブレイク, Kanashimi Bureiku, Sadness Break), and Love Bomber (ラブボンバー, Rabu Bonbā) finishers via the Gan Gun Saber.

Akari Tsukimura

Akari Tsukimura (月村 アカリ, Tsukimura Akari) is Takeru's childhood friend, college student, and physics major who wishes to be a successful scientist like her teachers. A rationally-minded young woman, she experiences difficulty in believing anything related to the supernatural and strives to find logical explanations despite learning of what happened to Takeru and assisting in reviving him. Along the way, she develops "Shiranui" (不知火) spray, which allows her to temporarily see Takeru as Kamen Rider Ghost and Gamma without an Eyecon. After finding a piece of a Gamma Eyecon, she is able to weaponize the Shiranui spray and use it to defend herself against Gamma. Following the Gammisers' defeat and Takeru's resurrection, she assists him in finishing his education.

Makoto Fukami

Makoto Fukami (深海 マコト, Fukami Makoto), original name Riyon (リヨン), is an artificial human created by Danton before his father Daigo spirited him and his sister Kanon to the human world and raised them until their mother died. Ten years prior to the series, Daigo left Makoto and Kanon at Daitenkū-ji, where the young Fukamis befriended Takeru and transported to Gamma World as a result of Chikara Saionji's machinations. After meeting Alia and Alain, Kanon's body died, leaving her soul trapped in a Gamma Eyecon. Seeking to revive her, Makoto obtained the means to become Kamen Rider Specter (仮面ライダースペクター, Kamen Raidā Supekutā), joined forces with Saionji and Alain, and returned to the human world to find 15 Eyecons, clashing with Takeru in the process. After Takeru gathers the 15 Eyecons and uses his wish to revive Kanon, Makoto vows to help revive him and leaves Kanon in Takeru and his allies' care while Makoto returns to Gamma World to regain his body with Javel's help. Following the Gammisers' defeat, Makoto and Kanon help Alain reform Gamma World.

During the events of the film Kamen Rider Ghost the Movie: The 100 Eyecons and Ghost's Fated Moment and the V-Cinema Ghost Re:Birth: Kamen Rider Specter, Makoto encounters and reconciles with Daigo upon learning of the latter's reasons for leaving him and Kanon as well as learns of his origins before stopping Danton from destroying Gamma World.

Similarly to Takeru, Makoto utilizes a Ghost Driver and his own series of Eyecons to transform into Kamen Rider Specter. While transformed, he gains superhuman speed. He also wields the Gan Gun Hand (ガンガンハンド, Gan Gan Hando, Eye Gun Hand), which like the Gan Gun Saber has several modes he can use depending on his form, can perform Omega Drive finishers, and possesses the Machine Hoodie (マシンフーディー, Mashin Fūdī) motorcycle, which contains Houdini's Hoodie Ghost instead of the corresponding Eyecon. In his default form, he wields the Gan Gun Hand in its club-like Rod Mode (ロッドモード, Roddo Mōdo), which allows him to perform the Omega Smash (オメガスマッシュ, Omega Sumasshu) finisher. He can also access other forms, which are as follows:

• Kamen Rider Deep Specter (仮面ライダーディープスペクター, Kamen Raidā Dīpu Supekutā): Makoto's super form accessed from the eponymous Ghost Eyecon, which is powered by the Gammisers, that enhances preexisting Damashii forms, grants the use of the Gekikou Mode (ゲキコウモード, Gekikō Mōdo, Enraged Mode) ability to manifest a pair of energy wings, and allows him to perform the Giga Omega Drive (ギガオメガドライブ, Giga Omega Doraibu) finisher. In this and all subsequent forms, he wields a variant of the Sunglasseslasher called the Deep Slasher (ディープスラッシャー, Dīpu Surassha), which has a Sword Mode for performing the (Giga) Omega Giri ((ギガ) オメガギリ, (Giga) Omega Slash) finisher and a Blaster Mode for performing the (Giga) Omega Dama ((ギガ) オメガダマ, (Giga) Omega Orb) finisher. However, as a side effect, the user will be left uncontrollable unless they use the Eyecon's power for righteousness.
• Kamen Rider Sin Specter (仮面ライダーシンスペクター, Kamen Raidā Shin Supekutā): Makoto's devil-themed ultimate form accessed from the eponymous Ghost Eyecon, which is powered by the seven deadly sins, that allows him to perform the Deadly Omega Drive (デッドリーオメガドライブ, Deddorī Omega Doraibu), Gluttony Bite (グラトニーバイト, Guratonī Baito), and Pride Fist (プライドフィスト, Puraido Fisuto) finishers on his own; the Envy Slap (エンヴィースラップ, Envī Surappu), Lust Bullet (ラストバレット, Rasuto Baretto), and Sloth Grave (スロウスグレイブ, Surōsu Gureibu) finishers via the Gan Gun Hand; and the Greed Slash (グリードスラッシュ, Gurīdo Surasshu) and Wrath Flame (ラースフレイム, Rāsu Fureimu) finishers via the Deep Slasher. This form appears exclusively in the V-Cinema Kamen Rider Ghost Re:Birth: Kamen Rider Specter.

Alain

Alain (アラン, Aran) is the son of Gamma emperor, Adonis, who seeks the Eyecons to examine their power and follows a twisted form of justice. He initially assists his family in combating Takeru Tenkūji and Makoto Fukami until Alain is framed for his father's apparent death. Unaware of his brother, Adel's, treachery, Alain attempts to take the throne from him while trying to adjust to life in the human world. Due to being rescued by Takeru and Makoto several times, Alain became honor-bound to help them. Upon learning that Adonis is alive, but trapped in his mortal body, Alain searches for him, learning the reason why he and the Gammas are immortal and learning more about Takeru along the way. After Adonis sacrifices himself to save him, Alain promises to carry out his father's will by saving the human and Gamma worlds, though he is temporarily unable to continue fighting until Makoto helps him come to terms with Adonis' death, vowing to defeat Adel himself. Following the Gammisers' defeat and the end of the Demia Project, Alain is pardoned and returns to his homeworld to help restructure the Gamma world's society with Makoto and his sister Kanon's help.

As of the crossover film Kamen Rider Heisei Generations: Dr. Pac-Man vs. Ex-Aid & Ghost with Legend Rider and the V-Cinema Ghost Re-Birth: Kamen Rider Specter, Alain has married Kanon.

Utilizing the Mega Ulorder (メガウルオウダー, Mega Uruōdā) brace and the Necrom (ネクロム, Nekuromu) Eyecon, the latter of which also allows him to brainwash Ghost Driver users, Alain can transform into Kamen Rider Necrom (仮面ライダーネクロム, Kamen Raidā Nekuromu). While transformed, he can control others' minds, turn intangible, transfer his consciousness to another Gamma's body and transform it into his own, and perform an Omega Ulord (オメガウルオウド, Omega Uruōdo) finisher known as the Necrom Destroy (ネクロムデストロイ, Nekuromu Desutoroi), though he is vulnerable to electricity-based attacks. Due to the Necrom Eyecon being a prototype, Alain is forced to absorb other Gamma to sustain his Rider energy and is unable to lose his temper lest the Eyecon destroys his body. Later in the series, he acquires a variant of the Gan Gun Hand called the Gan Gun Catcher (ガンガンキャッチャー, Gan Gan Kyatchā, Eye Gun Catcher), which has a Rod Mode for performing the Omega Crash (オメガクラッシュ, Omega Kurasshu) finisher and a Gun Mode for performing the Omega Finish (オメガフィニッシュ, Omega Finisshu) finisher.

During the events of the V-Cinema Kamen Rider Ghost Re:Birth: Kamen Rider Specter, Alain acquires the Yujou Burst (友情バースト, Yūjō Bāsuto, Friendship Burst) Eyecon, which is powered by friendship and allows him to assume his ultimate form; Yujou Burst Damashii (友情バースト魂, Yūjō Bāsuto Damashī). In this form, he gains the ability to perform the Burst Omega Drive (バーストオメガドライブ, Bāsuto Omega Doraibu) finisher.

Alain is portrayed by Hayato Isomura (磯村 勇斗, Isomura Hayato). As a child, Alain is portrayed by Yūsei Itō (伊藤 悠成, Itō Yūsei).

Recurring characters

Hoodie Ghosts

The Hoodie Ghosts (パーカーゴースト, Pākā Gōsuto), also known as Heroic Ghosts (英雄ゴースト, Eiyū Gōsuto), are hoodie-like spiritual entities who embody the spirits of historical figures. After being unlocked from an object tied to them, said figures later inhabit their respective Eyecons and can be summoned to augment their users with their powers.

Onari

Onari Yamanouchi (山ノ内 御成, Yamanouchi Onari) is a Buddhist monk and current caretaker of Daitenkū-ji due to Takeru being too young to do so who openly expresses his frustrations and is open to believing in the supernatural, but lacks the spiritual awareness to see Gamma without Akari Tsukimura's Shiranui spray or Takeru's Kumo Lantern. Over the course of the series and assisting in Takeru's fight against the Gamma, Onari develops an inferiority complex, believing himself to be a nuisance to the fight and desiring to provide better support.

As revealed in the tie-in novel Kamen Rider Ghost: Memories to the Future, Onari was an aspiring Mohawk guitarist who encounters Ryū after being saved from a Gamma Assault who arrived on Earth for reconnaissance purposes, eventually taking up the role of Daitenkū-ji's monk out of respect to his rescuer. At some point after the Great Eyeser's defeat, Onari left to establish his own private investigation service after getting into an argument with Javel, which also results in the former jumping into the crossfire between the Kamen Riders and Bi-Kaiser.

While Adonis used the Great Eye's power to complete Edith's machine, the latter was shocked to discover that it was slowly killing their people instead. When Adonis launched an invasion on the human world to power the machine, Edith attempted to contact the Great Eye, but was stopped by the Gammisers, which he created to protect it. A decade prior to the series, Edith was defeated by and joined forces with Ryū Tenkūji and Daigo Fukami to stop the Gamma, developing Ghost Drivers and heroic Eyecons for future use.

Ten years prior to the series, the former left on a ghost hunting expedition with his friends Chikara Saionji and Kenjirō Igarashi to research the monolith underneath Daitenkū-ji. Along the way, Ryū discovered an Eyecon and the Gammas. To prevent a war between Gamma World and his own, Ryū was forced to involve Takeru after sensing his potential for bringing peace between the two worlds. After Saionji sent Makoto and Kanon Fukami to Gamma World, Ryū leads a failed expedition to save them. Five years later, Ryū arranged for Takeru to receive the Ore Eyecon, which the former hoped would contain his soul and allow Takeru to fight Gammas in a duplicate body. After being killed by Adel however, Ryū was forced to adjust his plans. In the present, the latter gives up his soul to power the Toucon Boost Eyecon and buy Takeru time to revive himself.

In the tie-in novel Kamen Rider Ghost: Memories to the Future, it is revealed Ryū is the previous holder of Kamen Rider Ghost's mantle, having previously assumed a red-colored form called Kamen Rider Zero Ghost (仮面ライダーゼロゴースト, Kamen Raidā Zero Gōsuto) and fought the invading Gamma with the spirit of Miyamoto Musashi by his side and using the Gan Gun Saber's Nitouryu Mode as his weapon of choice. Having spent his final days fighting the invading Gamma forces, Ryū fought a young Adel before he was summoned by Saionji. Despite winning the fight with Musashi's help, Ryū was killed soon after when Adel transferred his spirit to a backup Eyecon. In addition, Ryū also joined forces with the younger Takeru and Ayumu in defeating Great Demia's clone during its attempt to prevent the young Tenkūji's birth in the past.

Ryū Tenkūji is portrayed by Kazuhiko Nishimura (西村 和彦, Nishimura Kazuhiko).

Gamma

The Gamma (眼魔（ガンマ), Ganma, lit. "Eye Demon") are extra-dimensional creatures that appear as ghosts in the physical world and are descended from humans who migrated from Earth to the Gamma World during the Yayoi period and lived peacefully. Though they founded an empire, the Gamma World was eventually devastated by environmental pollution associated with the rapid development of science and technology. When their ruler Adonis fell into despair after his wife Alicia and firstborn son Argos, among others of their kind, were claimed by a plague, he sought to use the Great Eye's power to wish for a world without death in what would be called the Demia Project (デミアプロジェクト, Demia Purojekuto), with his closest ally Edith overseeing it. Over time, Adonis and Edith developed a means of using the Great Eye's power to preserve Gamma World populace's bodies in stasis capsules while their souls are transferred into Eyecons that use nanotechnology to project facsimiles of their original bodies. However, the life support system required a great amount of energy to be maintained and several Gamma World residents began to die as such.

To compensate for this defect, Adonis' son Adel and Gamma scientist Igor suggested invading the human world, to which Adonis reluctantly agreed until he saw how his actions endangered the human world's inhabitants. This would lead to Adel overthrowing his father and being manipulated by the Gammisers for their own ends. Following Adel and the Gammisers' demise, the Great Eye's departure, the Demia Project being shut down, and peace being restored to the Gamma World, Alain returns to rebuild Gamma World's society.

Each Gamma possesses a Gamma Eyecon (眼魔眼魂, Ganma Aikon) that it can fuse with an object in the human world to help them transform from their Primal Body (素体, Sotai) into a more powerful form. From weakest to strongest, Gamma sub-species include Gamma Assaults (眼魔アサルト, Ganma Asaruto), who primarily serve as foot soldiers; Gamma Commandos (眼魔コマンド, Ganma Komando), whose Eyecons lack the energy needed to become more powerful and the majority of which were formerly humans before Igor developed technology capable of converting human souls into Gamma; Gamma Superiors (眼魔スペリオル, Ganma Superioru), who can assume human appearances with special Gamma Eyecons; and Gamma Ultimas (眼魔ウルティマ, Ganma Urutima), members of the Gamma World's royal family as well as promoted Gamma Superiors. Gamma Ultimas in particular are also capable of empowering themselves further via external methods, such as being possessed by a Gammiser, and become Gamma Ultima Fire (眼魔ウルティマ・ファイヤー, Ganma Urutima Faiyā). Gammas who absorb wild Hoodie Ghosts or constructs can transform further into a monstrous Giant Gamma (巨大眼魔, Kyodai Ganma), though they can be reverted back if they are separated from the Hoodie Ghost or construct. Similarly to the Hoodie Ghosts, Gammas can also use their Eyecons to possess living humans.

Javel

Javel (ジャベル, Jaberu) is a Gamma Superior loyal to Adel who sees Alain as foolish, though he allows Adonis to send him to support Alain in collecting the 15 heroic Eyecons. Despite being destroyed by Kamen Riders Ghost and Specter on separate occasions, Javel is able to use Igor's technology to resurrect himself. After Adel overthrows Adonis, Javel is promoted to Gamma Ultima and tasked with eliminating Alain, but is defeated by Kamen Rider Ghost Grateful Damashii despite being possessed by Gammiser Fire and transformed into a Gamma Ultima Fire. When Igor reveals he is no longer needed, Javel goes rogue and makes a final attempt at killing his enemies, only to discover he is dying of starvation due to reverting to his mortal body, which he hasn't done in years. Onari saves his life, causing Javel to realize the error of his ways and joins forces with Ghost, Specter, and their allies, though he initially maintains his mission to kill Alain until the Gamma prince defeats Javel in combat and the Gamma sees how Alain has changed. With Onari's encouragement, Javel changes his mission to learning more about the human world's environment. Amidst the Great Eyeser's attack, Javel sacrifices himself to save Alain, but Ghost destroys the Great Eyeser, reviving Javel in the process. Following this, Javel chooses to stay at Daitenkū-ji.

In combat, Javel can move at superhuman speeds, can produce energy waves from his palms, and possesses offensive power comparable to the Kamen Riders.

After convincing his father to invade the human world, Adel secretly works to terraform Earth by killing Ryū Tenkūji to stop him from interfering and sending Alain to retrieve the 15 heroic Eyecons. Eventually deeming Adonis too weak to follow through on the invasion, Adel destroys his Eyecon, imprisons him, and frames Alain for regicide while he assumes Gamma World's throne. However, he is unknowingly manipulated by the Gammisers into allowing them to merge with him to become the Perfect Gammiser (パーフェクト・ガンマイザー, Pāfekuto Ganmaizā) and influence him into seeking out the Great Eye's power. Following a failed attempt at using the Demia Project to turn everyone in Gamma World and the human world into copies of himself, his sister Alia and Ryū's son Takeru Tenkūji help Adel realize the error of his ways and admit that he killed Ryū out of jealousy. The Gammisers attempt to take over his body, but Adel urges Takeru to kill him. Before departing to the afterlife, Adel thanks Takeru for saving him and expresses the hope that his siblings do not make the same mistakes that he did.

Amidst Adel's attempt to use the Demia Project to turn everyone in Gamma World and the human world into copies of himself, Igor is rescued by Akari Tsukimura and repays her by sacrificing himself to protect her from a mind-controlled Gamma. Following Kamen Rider Ghost's battle with the Great Eyeser, Igor awakens in his mortal body.

Unlike other Gamma, Igor possesses a unique Eyecon that allows him to transform into a Gamma Superior Perfect (眼魔スペリオル・パーフェクト, Ganma Superioru Pāfekuto) and a Proto-Mega Ulorder (プロトメガウルオウダー, Puroto Mega Uruōdā) brace that allows him to assume the forms of Gamma Combatants via Gamma Change (眼魔チェンジ, Ganma Chenji).

However, her first attempt is thwarted by Gammisers Climate and Planet, who destroy her Gamma Eyecon and return her to her mortal body, allowing Adel to take her captive. Alain and his allies eventually free Alia, who helps Takeru return Adel to his senses. After the Gammisers fuse with the Great Eye, Alia elects to stay in Gamma World to protect it while Takeru, Alain, and their allies defeat the Gammisers.

Utilizing a Proto-Mega Ulorder and a pink-colored Necrom Eyecon, Alia can transform into Kamen Rider Dark Necrom P (仮面ライダーダークネクロムP（ピンク）, Kamen Raidā Dāku Nekuromu Pinku).

Adonis

Adonis (アドニス, Adonisu) is the emperor of the Gamma World and the father of Alain, Adel, Alia, and Argos who cares for his people and family. During the Yayoi period, as detailed in the tie-in novel Kamen Rider Ghost: Memories to the Future, Adonis led a group of people in migrating from Earth to Planet Gamma to protect them from a barbaric king. After losing his wife Alicia (アリシア, Arishia), firstborn child Argos, and many of his comrades, Adonis created the Demia Project to ensure immortality for the Gamma. Due to this, he was chosen by the Great Eye and used its power to realize his magistrate Edith's machine, which he developed to transfer the Gamma World's population's souls into Eyecons. However, the machine killed more of their people, which led to Adonis reluctantly approving his son Adel and scientist Igor's idea to invade the human world to solve the problem.

Over time, Adonis came to regret the innocent lives being taken, causing him to doubt his actions. Before he could call off the invasion, Adel destroyed his father's Gamma Eyecon, imprisoned, and framed Adonis' youngest son Alain for regicide. Alain and Takeru Tenkūji eventually free Adonis, who sacrifices himself to protect Alain from Adel's army. Dying in Alain's arms, Adonis reaffirms his love for him and tells him to listen to his heart in the hopes of stopping him from making the same mistakes that he did.

Following the Gammisers' defeat, Gyro is freed of the Demia Project and awakens in his mortal body.
