"The Dazzling Adventurer! Bouken Silver!"
―Bouken Silver's roll call[src]

Eiji Takaoka (高丘 映士 Takaoka Eiji) is the Dazzling Adventurer Bouken Silver (眩き冒険者ボウケンシルバー Mabayuki Bōkensha Bōken Shirubā) of the Boukengers.

Eiji is 24 years old when he joined the Boukengers.[1]



He is a descendant of the Takaoka Clan, those most likely responsible for having sealed the Ashu Tribe. He debuts in Task 17, as a monk-like warrior with a strange power in pursuit of the Ashu Tribe.

Eiji at first wielded Karato's shakujo. It allowed him to perform the "Takaoka-Style: Ashu Soul Destruction," which was effective on normal Ashu. But Gai, now a Quester along with Rei, broke the shakujo with his hip and gunned the ornament into oblivion. As a result, Eiji's Ashu lineage surfaced and nearly overtook. This was until SGS created the SagaSniper for him along with a GoGo Changer allowing him to transform into Bouken Silver.

Because his Accel Suit is connected to the new Neo-Parallel Engines, he is not affected by the Gordom Engine. Satoru told Eiji that the SagaSniper had the same power as his shakujo. But this was eventually revealed as a lie, since Satoru knew that Eiji's heart fought against and could control his Ashu side with his own power.

When offered to be the Boukengers' comrade he initially agreed, but when he remembered his father Karato he hesitated and ran away. After talking with Natsuki and seeing his mother's tear, he realized his place in the world and joined the Boukengers officially. He joined the SGS Rescue division and received his silver jacket.

His rivals are the Ashu Tribe & the Questers, specifically Gai. When Ouga was awakened, Eiji attempted to perform the Ashu Soul Destruction on Ouga. But his soul was dragged by the Ashu into the limbo between worlds. However, Eiji managed to defeat Ouga there and managed to return to his body and help the others fight the Questers. In the end, Eiji finally defeated Gai as he had vowed and later setting up grave markers for him and Rei as a sign of respect.

During Boukenger vs. Super Sentai, to help his comrades, Eiji gave the Spirit of Hope to AkaRed to power up DaiVoyager to its Burning Legend form. When Masumi took leave, Eiji filled his spot during mecha formations.

In Task 48, Eiji is reunited with his mother Kei once more in the house where he grew up in, and she helps Eiji discover what his personal treasure is, which is to have his own adventure.

In the finale, after the final battle with Gajah, Eiji spends the majority of his time in rescue work at SGS Rescue, assisting the Boukengers on the side until a new BoukenRed and BoukenPink are recruited.

Legend War

A few years later, Eiji fought alongside not only his own team, but every single Sentai ranger in existence, against the Empire of Zangyack 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, he gathered all the Rangers together and gave them the order to sacrifice their powers to wipe out the first invasion's armada.

Zyuohger vs. Ninninger

The first 38 Sentai projected into Wild Tousai Shuriken King.

Bouken Silver appeared with his team among the first 38 Super Sentai whom collectively empowered Wild Tousai Shuriken King in its fight against the titanic Gillmarda, granting the Ninningers and Zyuohgers the power to perform the Zyuoh Ninnin Super Sentai Burst which destroyed Gillmarda with the combined power of all 40 Super Sentai.

Super Sentai Strongest Battle

Eiji joined the Super Sentai Strongest Battle as a member of Vehicle Team. In the first round, his team fought against Legendary Team, with Bouken Silver engaged ChangePegasus. In the second round, Eiji and Go-On Red fought AkaNinger and Sasori Orange of Oddball Team. When he clashed with Sasori Orange, he revealed that he was unable to contact the SGS even though he could still transform. Although his duo was having an upper hand in the fight, Eiji and Sosuke accidentally crashed into each other and was knocked out of transformation. While they were busy arguing, Oddball Team was able to grab the gem and won the battle. Disappointed, Eiji told his successors to continue their Precious adventure with their teammates, before disappearing. Tvicon.png TV STORY-Battle1: Who is the Strongest in History!?


Aloof and somewhat arrogant, to Eiji, the world's Precious are of little value to him; all that concerns him is the Ashu Tribe. And this attitude tends to rub others the wrong way, especially Masumi. Furthermore, Eiji's father Karato had history with the Ashu and was slain by Gai, which is the source of Eiji's aggression. His source of aggression is also the fact his own mother Kei was an Ashu as well, making Eiji a half-human half-Ashu hybrid who believed his birth was an excuse to continue the Ashu bloodline.

Transformation and Roll Call

Ranger Key

The Bouken Silver Ranger Key.

Mobilates'/Gokai Cellular's Gokai Change announcement[src]

The Bouken Silver Ranger Key (ボウケンシルバーキー Bōken Shirubā Renjā Kī) is Eiji Takaoka'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 other fourteen sixth ranger keys and the ten extra hero keys, were initally acquired by Basco ta Jolokia and later used by the Gokaigers. Like all of his Ranger Keys, Basco used his trumpet, the Rapparatta, to turn the Bouken Silver key into a puppet to do his bidding. The copy Bouken Silver was one of the remaining ten sixth rangers after the Gokaigers defeated the first five, with Basco using these ten to ambush the Gokaigers and take all of them hostage bar Marvelous. When Marvelous rescued them, they defeated all 10 puppets and claimed the Ranger Keys.

A short while after, the first fourteen Sixth Ranger Reys, 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. The Bouken Silver key was among ten of these Sixth Ranger Keys who fought, and were defeated by, Gosei Knight. Tvicon.png TV STORY-Gokaiger Goseiger Super Sentai 199 Hero Great Battle

While in the possession of the Gokaigers, the Bouken Silver Ranger Key was mainly used by Gai Ikari (Gokai Silver), who used it to fight as Bouken Silver. It was also used by Captain Marvelous (Gokai Red) on one occasion.

After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. It is presumed that Eiji received his key and became Bouken Silver once more.
