This is about the anime characters. For the monster itself, see Jura Wall.
The Jura Walls are a group of scaley Monols who are supporters of Moo's regime. After he falls, they allign themselves with Durahan's rebel forces.
The Jura Wall troops and their captain follow Genki's team across a huge swamp, intending to steal the Dark Disc for Durahan. Luckily, they find a taxi driver to help them outrun the evil Monols.
