Virus is a sadistic Toko that loves watching others squirm in fear. He works side by side with his brother Trip, both of them being rogue Tokos that live outside the ranch boarders. Both of them seem to have an infatuation toward the ranch's lilac male Aoba and, because of this, are usually found pestering him whenever the chance arises, only to be chased off by Mink or Noiz. Virus is, however, the more intelligent of the duo, being sly and always knowing how and when to strike when hunting. He is also extremely patient, knowingly unnerving his prey by stalking them for days on end. All in all, Virus is a sadistic Tokota that isn't afraid to attack and frighten anyone he doesn't deem worthy of his time.
