Julia is a Child in the Mai-HiME continuum of the Mai-HiME Project.

In appearance Julia resembles a giant spider with a scorpion's tail and a female humanoid face. She is the Child of Nao Yuuki. Julia has several combat abilities, such as being able to emit sticky webbing from her chest, striking with her tail and releasing a caustic substance from an opening in her chest.

Julia is most likely based on Atlach-Nacha, a goddess in the post-Lovecraftian Cthulhu mythos. Atlach-Nacha is the invention of the writer Clark Ashton Smith and was a large spider with a humanoid face, similar to Julia.
