Eruzu (エルズ, Eruzu) is an arachnid Horror that possessed an unnamed young girl.
Eruzu used her host to target aggressive men. Her abilities, other than spider-related powers, include each surviving piece of her body being able to regenerate into a new Horror. Because of this, Garo could not simply cut her down and had to burn her whole, using his Blazing Armament technique.
