Biology
Arachnevil strongly resembles Arachnus and Arachnia, the color scheme, however, is noticeable different: Arachnevil's hair and hakama are colored red, his shirt has a dark shade of gray, his jacket is black, and the markings in his face are entirely black. The other most noticeable difference are his fairly long, straight black oni-like horns that jut out from his forehead.

Etymology

 * "Onigumo" translates as Oni Spider.
 * "Arachnevil" is a portmanteau of Arachnus (or Arachne), and evil.

Origin
While "Onigumo" doesn't have a mythological basis, it is the name of a species of common orb-weaver spider, Araneus ventricosus.
