Yokai Buruburu

Yokai Buruburu appeared in 2015 TV special called Shuriken Sentai Ninninger Vs. Kamen Rider Drive Spring Vacation Combining Special. Yokai Buruburu (妖怪ブルブル Yōkai Buruburu, lit. "to shake") is a Yokai which appear in Shuriken Sentai Ninninger Vs. Kamen Rider Drive Spring Vacation Combining Special.

Later, Roidmude 089 (ロイミュード０８９ Roimyūdo Nanbā Zero Hachi Kyu), a Spider-Type Low-Class Roidmude, that affiliates with Shocker and the Kibaoni Army Corps, used the purified Sealing Shuriken following Buruburu's death to become Shocker Buruburu (ショッカーブルブル Shokkā Buruburu).

Yokai Buruburu was created when the corrupted Sealing Shuriken infected a Spider Viral Core by Kyuemon Izayoi via the Roidmudes' cooperation. This Yokai was first sent to help Kyuemon gather the human fears by attacking several civilians. The Ninningers transformed and fought the Yokai but overpowered by it's ability to induce a strange wave that decelerated their movements as he overpowered them and take his leave.

The Ninningers (minus Takaharu) fought Buruburu with Takaharu brought Shinnosuke to the location. Takaharu and Shinnosuke arrived to the spot but instead, they witnessed the other Ninningers shivering in fear and attacked Takaharu, seemingly emitted the Heavy Acceleration until Takaharu solved it and reveal the Yokai, gaining Shinnosuke's trust. He and the other Ninningers regrouped and battled Buruburu, killing him with Simultaneous Ninja Violent Slash.

Using his Sealing Shuriken, Yokai Buruburu was "reincarnated" as Shocker Buruburu by Roidmude 089, becoming his advanced form and attacking several construction workers while dueling the Ninningers (save AkaNinger). He also called up another lackey, Roidmude 076 for assistance whom lead leftover Hitokarage. Eventually, a battle raged between the Sentai and Riders against Shocker armies. He was finally defeated by Drive Type Formula's Trailer Impact and Deadheat Mach's Hit Macher.

Born from a Viral Core, Buruburu had a tendency to repeat his name in most of his speech. He was very loyal to the Shocker, Roidmude, and the Yokai cause.
