Avenger (復讐者, Fukushū-sha?) is a Class Skill of the Avenger class, representing the state of an Avenger as one that gathers people's hatreds and grudges onto oneself. The Skill makes it easier for the user to accumulate hatred and resentment, which are then turned into power for the Servant.[1]
Ishtar Ashtart was once a great goddess whose anger caused sadness and suffering which was praised by the devil. Although she admits that she is evil, she stands on the side of justice and order, and is somewhat unqualified to be an Avenger.
A state of being that gathers the grudges and hatred of men turned into a skill. Her body continues to be subjected to the grudges and hatred of the masses even now.[3]
