Irisviel von Einzbern

Irisviel von Einzbern is the lead female character of Fate/Zero. She is a homunculus coined by the Einzbern family based on the archetype of Justeaze Lizrich von Einzbern, thus referred as a Justeaze-late model. The one who became the mother body of the ultimate homunculus, among all Einzbern homunculi in the past, she is the only who experienced motherhood and gave birth to a successor. She loves Kiritsugu Emiya, her husband, and Illyasviel von Einzbern, her daughter. In spite of his normally restrained attitude, Kiritsugu calls her "Iri" out of affection. Irisviel is a vessel of the Holy Grail, but compared to Illyasviel, she is a less refined model.
