Who is Heihachi Mishima's wife and Kazuya's mother in Tekken 7?

Kazumi Mishima is Heihachi Mishima's wife and Kazuya Mishima's mother in Tekken 7.

Tekken 7 expanded the Mishima family history by finally showing Kazumi, who had previously been mentioned only indirectly. She met Heihachi while visiting Jinpachi Mishima's dojo, grew close to him, and married him. Their son was Kazuya, whose later conflict with Heihachi forms the central family feud of the series.

Kazumi is also important to the Devil Gene storyline. The game reveals that she belongs to the Hachijo clan and possesses a devil transformation. Her clan sent her to assassinate Heihachi because it foresaw his future attempt at world domination. After Kazumi tried to kill him, Heihachi defeated her in self-defense.

Jun Kazama is Kazuya's partner and Jin's mother, not Kazuya's mother. Anna and Nina Williams are unrelated to the Mishima family. Kazumi also serves as Tekken 7's arcade-mode final boss, making her identity central to both the plot and gameplay.
