She tells Akuma that Heihachi must be killed to stop the loss of innocent life he will inevitably cause in the future. A subsequent montage of destruction attributed to Heihachi also includes crimes committed by Kazuya and Jin, implying that Heihachi is responsible for setting in motion all those subsequent evils. In the story trailer narrated by her, her feeling towards Kazuya indicate that she primarily fears what Heihachi will do to their little son when he discovers he has her powers. She then adds 'and also, unfortunately, my dear son, Kazuya', implying that she is also ordering Akuma to kill him. In Tekken 7: Fated Retribution during Akuma's reveal trailer, Kazumi is shown to have an antagonistic side towards her husband, as she tells Akuma he must kill him if she fails to do so. In one of her win animations, she is shown petting her tiger happily. In Kazumi's case, she trained a pet tiger which she can summon at will as part of her moveset, unlike Heihachi who trained Kuma but cannot summon him at will. Kazumi also seems to share her husband's affinity for animals. She also uses the formal and antiquated first person pronoun 'watakushi' (わたくし). Kazumi is shown to be quite honorable and formal, as, in one of her intro animations, she formally bows to her opponent while announcing she will be their next opponent. Her name was also briefly mentioned in Tekken 2's musical score. The second and last time was in the non-canon OVA film Tekken: The Motion Picture, where she was just referred to as 'Kazumi' at the time. 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 ). She was originally one of the unplayable bosses along with her grandson, Jin, prior to the release of the Arcade version. She was introduced in Tekken 7 as a new character, and as the posthumous antagonist of the game.

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. Yumi Hara Kazumi Mishima ( 三島一美, Mishima Kazumi ?) neé Hachijō ( 八条, Hachijō ?) is a character in the Tekken series of 3D fighting games.
