|“||Looks like it's time...for the walls to come down!||„|
|~ Yokai Nurikabe's final words before his death.|
Yokai Nurikabe is the main antagonist in episode 22 of the 2015 TV series Shuriken Sentai Ninninger. He is a railroad crossing signal-themed Yokai. He is also called "Misleading Wall Nurikabe" in his introduction credits.
He was voiced by Yasuhiko Kawazu.
Although seen off-screen, Yokai Nurikabe was presumably created by Kyuemon to destroy the Ninningers and generate more fear. He then goes to earth to create massive walls showing unfortunate truths to people to generate fear (such as parental objections for two lovers and the expectation of high grades for a failing student). He battles the Ninningers when they arrive with Ariake No Kata threatening to turn him into an actual wall if he failed.
The Ninningers tried their hardest to defeat him but weren't powerful enough to stand up against Nurikabe's durability and firepower and he quickly sealed Kinji and Yakumo within two walls and fought the other Niningers. The remaining heroes got pounded by him, Kyuemon, and Ariaka until Yakumo freed him and Kinji. At this point, Ariaka left him to battle alongside the Jukkarage.
He did battle again with Kinji and Yakumo whilst Takaharu morphed into his Chozetsu armor At this point, they combined powers by using their Transcendant Strike and hitting him with Kinji and Yakumo spinning rapidly to defeat the Yokai. Kyuemon then made Nurikabe grow so they summoned Shuriken Gattai Shurikenjin, BisonKing, and Lion Ha-Oh into battle. They were quickly overwhelmed when Ha-Oh's Giant Shuriken Crush was deflected back into the formation by his Impenetrable Nurikabe Shield so they were forced to create Ha-Oh Shuriken Gattai Ha-Oh Shurikenjin for the first time. Nurikabe used his Nurikabe Shield but a barrage from Ha-Oh's cannons obliterated it. Akaninger then leapt atop the formation and, with the Ha-Oh Splendid Buster attack, Yokai Nurikabe was gone for good.
Nurikabe was among ten Yokai who appeared alongside Kyuemon Izayoi and the Western Yokai Wolf Man to Kinji in his vision after he had transformed into reincarnation of the Wolf Man, all bearing his face. When Kinji overcame his fear and doubt, and thus his Yokai side, he used the Demon Sword Urasame to vanquish all of the illusionary Yokai and return to the real world.
Nurikabe's likeness appeared among a set of Yokai karuta cards assembled by Shurikenger for the Ninningers to analyze the Yokai they had defeated so far. Due to Yokai Fudagaeshi's dark art Karuta Dance, Nurikabe was one of six illusionary Yokai which manifested from their respective karuta cards in the Igasaki Ninjutsu Dojo. The illusionary Nurikabe was subsequently destroyed by ShiroNinger's Karakuri Hengen Bow.
