"There is darkness within you, Masumi Inou... That is the absolute truth... You'll never escape from the Darkness... The power of darkness can never be... Destroyed!!"
―Yaiba's final words to Masumi.[src]

Yaiba of Darkness (闇のヤイバ Yami no Yaiba, 3-46) was a deputy leader of the Dark Shadow, serving Gekkou of Illusions alongside Shizuka of the Wind. He betrayed the group near the final to siphon darkness for his own in order to cover Earth with darkness until his destruction by Bouken Black, making him the most evil and powerful of the Dark Shadow. He is also nicknamed as "the paper crane ninja".



Encounter with Masumi Inou

Though he wears a face guard, it opens up to a terrifying monster-like face when he is about to kill, performing the "1000 Paper Crane Dark Blizzard" that summons a hail of deadly colorful origami cranes that repeatedly strike and slash the enemy. Yaiba used that attack to slay Masumi Inou's abusive excavation group when Masumi himself was little, and since then a rivalry/grudge has grown between them.

The Steel of the Heavenly Mine

Pursuing the Steel of the Heavenly Mine at Akaneasake, Yaiba and Shizuka attacked Bouken Yellow and fought her off. Exploiting her ignorance of her past, they arranged for Nendogami to take the form of a girl who claimed to be Natsuki's sister in an attempt to acquire the ore destroy the Boukengers. The team was able to get through to Natsuki, however, and defeated Nendogami while recovering the ore. Tvicon.png TV STORY-Task. 14: The Revived Past

The Ashu Mirror

Engaging in another skirmish with the Boukengers having acquired the Hundred-Demons Mirror, Yaiba and Shizuka were confronted by the Furious Demon God Gai and Grand Beast Rei who took the Mirror containing their fellow Ashu for themselves. Retreating with a dismayed Shizuka, Yaiba contacted Gekkou who warned his servants that the Ashu, who would emerge as their own Negative Syndicate, were not to be underestimated.

The Hyde Gene

Receiving word from a messenger offering a powerful Precious, Yaiba and Shizuka, backed-up by Tsukumogami revived by Gekkou, fought with the other Negative Syndicates in an attempt to claim it. Ultimately, it was the Boukengers who uncovered the living Precious, Hyde Gene, and prevented it from wiping out life on Earth.

God's Head

Obtaining the God's Head, Yaiba and Shizuka arranged to sell the Precious for a great sum of money which would allow them to renovate Dark Shadow's base while concocting a decoy to split up the Boukengers' efforts to intercept. However it was a trick with both set up as traps: Yaiba led Masumi, Natsuki and Eiji into a fight with himself and Karths while Shizuka trapped Souta and Sakura in a science complex taken over by the supposed God's Head, in actuality the Tsukumogami Mamorigami. The true God's Head appeared to be actually sold off to a person in the black market, but ultimately the Boukengers had one-upped the Dark Shadow: the informant they sold it to was Akashi in disguise, while the Akashi who appeared to help them out was actually Morio sent to make them think that the whole team was there and that their mission had failed.

Fall of the Questers

Promised the defeat of the Boukengers, Yaiba and Shizuka were manipulated by the Questers into stealing the Paracelsus' Mercury from a high security chemist museum for them. With the Gordom Civilization and Jaryuu Clan providing Precious as well, all three Negative Syndicates were double-crossed by Questers who took the respective Precious into the Mercurius Vessel, allowing them to create the Ultimate Artificial Lifeform Homunculus which made them an unstoppable force.

Betrayed by the Questers whom embarked on a campaign of destruction against humanity after overwhelming the Boukengers in Homunculus, Yaiba and Shizuka met up with Arch Priest Gajah of Gordom and Creator King Ryuuwon of Jaryuu, contemplating the coming showdown between the Questers and the Boukengers. Ultimately, the Questers were eventually defeated by the Boukengers and Zubaan with the combined strength of all their mecha, finally vanquishing their Ashu rivals.

Yaiba attempts to entice Masumi into unleashing his inner darkness.

Yaiba also revealed to Masumi that he let him live that day because of the darkness in Masumi's heart when he used the excavation group as a shield. After being labeled a traitor to Dark Shadow for summoning the Demon Bird, Yaiba reveals that he used the group to perfect his dark power to use the Three Headed Dragon of Darkness to bring eternal darkness to Earth with Yaiba ruling over it. However, it rejected him as his darkness wasn't worthy. However, Yaiba had a back-up plan, which was why he allowed Masumi to live and have him embrace his own darkness. From there, Masumi would use the Precious' power to Yaiba's intent.

However, when Yaiba exposed his goal to Masumi, the light within Masumi grew stronger and both engaged in combat while the others stopped the darkness. In the end, Yaiba was ultimately destroyed by Masumi's Hammer Dynamite, but tells him that his darkness is eternal. These words forced a guilt-ridden Masumi to leave the team.
