Nurikabe is a Giant-Type Makamou with a snail head and a Bagworm moth body and an antagonist in Kamen Rider Hibiki.
Kamen Rider Hibiki
It initially posed as a tree in Shimotsuke before it began heading towards the city to devour more people. It was destroyed by Hibiki in his Mouka Dotou form.
During the start of Orochi, a Nurikabe appeared at the Western House. The Man attempted to seal it but was unable to, so he and the Woman destroyed the berserk monster.
Nurikabe appears as one of Dai-Shocker's Great Commanders. He takes on the Gokaiger successfully, but is later seemingly defeated by the combined Rider and Super Sentai forces. His human identity isn't made clear in the movie.
