"The Fiery Adventurer! Bouken Red!"
―Bouken Red's roll call[src]

Satoru Akashi (明石 暁 Akashi Satoru), nicknamed "Chief" (チーフ Chīfu) by his fellow Boukengers, is the Passionate Adventurer Bouken Red' (熱き冒険者ボウケンレッド Atsuki Bōkensha Bōken Reddo) of the Boukengers. Driving the GoGo Dump and the GoGo Commander, he leads the team with a calm expression and a fire in his heart, mainly battling King Ryuuwon of the Jaryuu Clan.



Satoru is the chief of the Search Guard Success Foundation and the Fiery Adventurer. Once an enthusiastic treasure-hunter known as the "Immortal Fang," the tragic deaths of his partners Kyouko and Masaki in a blaze trap made him retire, only to be hired by SGS. With a calm exterior, Satoru actually hides hot blood inside, as evidenced when he simply catapulted Masumi Inou and Natsuki Mamiya into the Go Go Dump's bucket and carried them and an entire tub of dirt and gravel at full throttle out of the Gordom temple before dumping the entire load upon coming to a full stop. He says "Attack!" and simultaneously snaps his finger at the end of each order he gives to the others. He refers to the other Boukengers by their respective colors, something that Masumi has a thing against.

He is also seemingly oblivious to Sakura Nishihori's heavily implied attraction to him as he is a workaholic. He became filled with self-doubt in Task 4 after Go Go Vehicles 1~5 were buried under ice in a deep crevasse, the resulting suffering of his teammates sparked his memories of Kyouko and Masaki. It took his mighty willpower for him to control the overload-prone GoGo Drill and prevent history from repeating itself.

Satoru used to be a huge fan of Jimon Kagawa's writings about heroes. He is a constant rival of Ryuuwon and took Ragi, a human whom Ryuuwon had transformed into a Wicked Dragon, under his protection and received "the Greatest Adventure" while restoring the Water Metropolis. During the events of the Boukenger movie, Satoru encountered his father Kouichi, whom he eventually settled his affairs with. Satoru was given the offer to quit the Boukengers and join SGS Rescue, but he refused, because he likes to have his own adventures. Instead, he gave Eiji Takaoka the GoGo Changer.

Satoru has at times gone off by himself to find Precious or protect his comrades. In Task 10-11, he let Ryuuwon and Arch Priest Gajah take DaiBouken with him inside to the secret island where SGS kept the Manuscript of Leon Giordana. In Task 42, when most of the GoGo Vehicles were damaged by Furious Demon God Gai and Grand Beast Rei's new Homunculus, he took SirenBuilder, since Eiji at that time was frozen in stone and was never used, to go stop the Quester controlled Homuculus. His real intention was to detonate SirenBuilder with the Homunculus holding on, but everyone came in time to tell Satoru that they are a team and cannot do everything alone. He fought Ryuuwon for the final time, only to endure the destruction of the Precious Bank thanks to DaiKenjin Zubaan. He then followed Desperado in the modified DaiVoyager.

Six months after the final battle with Gajah, Satoru left the Boukenger team to take on a new adventure by taking the space-worthy GoGo Voyager into space to fight outer space Precious, though he was surprised that Sakura followed him, and apparently utterly clueless as to her true intentions. However, when Sakura is possessed by Pachacamac, Satoru is forced to aid him in obtaining the two jewels the monster needed to regain his power. Once Sakura is freed, Satoru aids his team and the Gekirangers in defeating Pachacamac.


Legend War


A few years later, Satoru fought alongside not only his own team, but every single Sentai ranger in existence, against the Zangyack Empire when it attacked the Earth in the Great Legend War. After fighting against hundreds of Gormin and their Zgormin commanders, AkaRenger noticed the fleet moving towards them and gathered all the Rangers together and gave them the order to sacrifice their powers to wipe out the first invasion's armada. After the Great Legend War, Satoru, alongside Go-Onger Saki Rouyama, is the one who informs the Goseigers that they destroyed the Zangyack's first invasion.

The Adventurer Heart

Satoru appeared in episode 21 of Gokaiger. Because the Boukengers support the collection of precious items from adventures - as was the case with the Akaki pirates and the Ranger keys - he begins by reassuring the Gokaigers that his team will not try to take their Keys back. He then asks for the Gokaigers' aid in retrieving The Heart of Hades (黄泉の心臓 Yomi no Shinzō), a powerful Precious. During the mission, Akashi taught Marvelous about having an Adventurer's Heart. At the end of the episode, Satoru mentions AkaRed, wondering if this is best for him.

Farewell Space Pirates

After the Zangyack's final defeat, Marvelous returned the Ranger Keys to their original owners. It is assumed Satoru and the rest of his team got their powers back. Final Ep.: Farewell Space Pirates

Super Hero Taisen

The Boukengers, alongside the Abarangers, Hurricanegers, Magirangers, and Dekarangers, emerge through a dimensional wall.

Satoru, alongside his team (Bouken Silver and Zubaan were absent), among the majority of the Super Sentai heroes, was caught up in the "Super Hero Taisen" incident which eventually resulted in the Super Sentai teams and Kamen Riders joining forces to defeat both Dai-Zangyack and Dai-Shocker. During the final battle, he is seen fighting Kiaido and the Armadillo Orphnoch. Kamen Rider × Super Sentai: Super Hero Taisen

The five-man Boukenger team was part of a force of Sentai and Rider reinforcements led by Akarenger and Kamen Rider #1Icon-crosswiki.png that came to assist the Sentai and Riders of recent years who were overwhelmed by the revived monster army of the Space Crime Syndicate MadouIcon-crosswiki.png. The combined forces of superheroes were able to turn the tide against the Madou army. They lined up and used their various finisher attacks to destroy the revived monsters.

After Demon King PsychoIcon-crosswiki.png was destroyed and the battle was finally over, the Boukengers appeared standing on a cliff with all the other heroes who appeared to help, to say goodbye to the heroes of recent years before taking their leave.

Bouken Red appeared as part of a conference of the first 38 Reds led by Red Falcon, whom addressed the Ninningers and Zyuohgers as the greater Super Sentai pantheon intervened to save them from defeat at the hands of the titanic Gillmarda. Empowering the Combination Nin Shuriken to form Wild Tousai Shuriken King, the first 38 Super Sentai further imbued their successors with the power to perform the Zyuoh Ninnin Super Sentai Burst, destroying Gillmarda with the combined power of all 40 Super Sentai.

Appearances in other media



MagiRed (outside) calls Bouken Red (black background) through his MagiPhone. Through a split-screen effect, Bouken Red turns his attention toward the viewers, posing. This is, so far, the only Hand-Off where the two Reds do not physically meet one another, with MagiRed instead making phone contact with Bouken Red (Satoru Akashi) from a different location. This is also the only Hand-Off between two Reds who did not meet up in a subsequent team-up focused exclusively on their teams' meeting (ie. not counting the Legend War, where they did not interact with each other anyway).

Lucky Bouken Red

Lucky Mode

Akashi donned a good luck outift in Task 27: The Feng-Shui Trap, which he later wore as Bouken Red. The whole team donned "Lucky Mode" (referred by Akashi as "Courageous Mode") in the The 30 Sentai Encyclopedia file of Task 46: The Awakened Darkness, in a parody of the Power-Up Henshin. The lucky outfit was later worn by the imaginary Bouken Red in his first appearance in Akibaranger episode 3.

Bouken Scooper

In order to help Akibarangers, the imaginary Bouken Red transformed into Bouken Scooper (ボウケンスコッパー Bouken Sukoppā), the Ludicrous Power of the Boukengers. The Bouken Scooper is wielded by Akiba Blue. Bouken Scooper is based on DaiBouken's Go Scooper. The Bouken Scooper is strong enough to be used as a drill and a normal spade. As a drill, the user can also drill in along with it for hiding purposes.

Legend Sentai Devices

The Bouken Red Ranger Key.

The Bouken Red Ranger Key (ボウケンレッドレンジャーキー Bōken Reddo Renjā Kī) is Satoru Akashi's personal Ranger Key and what became of his powers after he along with the rest of the 34 Super Sentai sacrificed their powers to end the Great Legend War.

This key along with the majority of the Ranger Keys were collected by the Red Pirates and later used by the Gokaigers. Marvelous and AkaRed found the Bouken Red key together, with AkaRed saving Marvelous from a trap shortly before. Ep. 21: The Adventurer Heart The Bouken Red Ranger Key was mainly used by Captain Marvelous (Gokai Red), who used it to fight as Bouken Red. It was also used by Joe Gibken (Gokai Blue) and Gai Ikari (Gokai Silver) on several occasions.

The Boukenger keys, along with all the Ranger Keys of the first 33 Super Sentai, were briefly taken by the Black Cross King and turned into Ranger puppets that were fought by the Gokaigers and the Goseigers. Splitting up, the puppet Bouken Red was defeated as part of a group of surviving Red warrior keys by Gokai Red and Super Gosei Red. Gokaiger Goseiger Super Sentai 199 Hero Great Battle

After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. Satoru received his key and became Bouken Red once more. Final Ep.: Farewell Space Pirates

Marvelous discovers the Bouken Red Ranger Key, with AkaRed by his side.

Behind the scenes


Satoru Akashi is portrayed by Mitsuomi Takahashi (高橋 光臣 Takahashi Mitsuomi). As Bouken Red, his suit actor was Hirofumi Fukuzawa (福沢 博文 Fukuzawa Hirofumi).


  • "Akashi" (明石) is from the surname of Japanese officer Motojiro Akashi (明石 元二郎 Akashi Motojiro), who entrapped Russia to confusion as a spy of the imperial Japanese army in the Russo-Japanese war.
  • The kanji for "Satoru," "暁," can also be read as "sunrise" ( akatsuki, literally red dawn). "Satoru" is also Japanese for "to realize".
  • The First 3 Letters in his Surname (Aka) also refers to the kanji for his color

Dub names

In the Korean dub of Boukenger entitled Power Rangers Treasure Force, which aired in South Korea, Satoru is renamed Caine.


  • Satoru's personality is based off of Tsuyoshi Kaijo (Akarenger) from the original Sentai series, Himitsu Sentai Gorenger. However, his love of adventuring is similar to another Red: Ken'ichi Akama (GoggleRed) of Dai Sentai Goggle V.
  • Due to his own anniversary connection, Akashi is the only Sentai Legend who has admitted to meeting with AkaRed outside of Captain Marvelous.
    • The only other Sentai hero who had met with AkaRed and appeared in Gokaiger as well was Nanami Nono (HurricaneBlue), but she did not mention it during her appearance.
  • In Gokaiger, there is a deleted scene of him with a Legend Shift.
  • Is the last Core Red Ranger to not have a child portray in a flashback or outside then until RyusoulRed (Thirteen years later).
