Kazumi Mishima (三島 一美 Mishima Kazumi?) née Hachijō (八条 Hachijō?) is a character in the Tekken series. She is the late wife of Heihachi Mishima, the late daughter-in-law of Jinpachi Mishima, the late mother of Kazuya Mishima and the late paternal grandmother of Jin Kazama. She was introduced in Tekken 7 as a new character, and as the antagonist of the game.
The existence of the character before Tekken 7 was alluded to twice: the first time was in Heihachi's Tekken 2 stage, in which their names ("Heihachi and Kazumi") are written on the floorboard of the temple in the style of Aiaigasa, a romantic expression to show the love between couples (the floor carving mark itself was later seen again in the very first trailer of Tekken 7[4]). The second and last time was in the non-canon OVA film Tekken: The Motion Picture, where she was simply referred to as "Kazumi." Her name was also briefly mentioned in Tekken 2's musical score.
