Abengane

Abengane is a Nen user.

Powers and Abilities
Exorcism: Abengane's ability requires him to first burn a campfire. He takes a wooden effigy and chants a prayer to forest spirits. He takes a branch of leaves, weaves a netted decoration around the doll, and burns it in the fire. The size of the fire shows how powerful the Nen that has to be removed is. The campfire rages, amassing the auras of the flora and fauna of the forest alongside Abengane's to conjure a beast from their combined Nen. The beast generated is able to exorcise Nen curses from people by devouring them, though it will linger until the originator of the ability has died or Abengane satisfies the conditions to disarm the curse. No Nen beast can exorcise a curse left by the dead. The size and shape of the beast depends on how powerful the curse is.
