"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 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".
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.
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.
Yaiba is revived as part of Dai-Zangyack. When Dai-Zangyack unites with Dai-Shocker, they battle the army of Kamen Riders and Super Sentai, including Yaiba's enemies the Boukengers. During the charge, he is seen throwing a punch over GokaiRed, which is caught by GokaiPink. In the battle he is seen fighting KirinRanger, GingaRed, Heart Queen, and GingaPink.
