Lemmings

Lemmings, or Nezu, is a killer and star member of Takeru Shinoyama's Dragon King's Palace Agency. Though most Shinjuku residents consider him an urban legend, Comps-3 has linked him to more than one crime and seeks his capture.

Lemmings was haunted by the souls of his victims until his attack at Youtoukorou, during which the Corpse God used most or all of the souls to replenish his magic. Possessors of the Evil Eye would have seen that the souls had been warped by their competing fear and loathing for their murderer.
