Kazumi Mishima (Tekken) (2024)

Many years ago, Kazumi Hachijo arrived at Jinpachi Mishima's dojo when she was a young girl. As she trained alongside Heihachi, they became fierce rivals and eventually fell in love. Kazumi then gave birth to their son, Kazuya, and she was enamored by and doted on him. But the family's days of happiness came to and end one day when Kazumi collapsed with a fever during training. While Heihachi was treating her, she got up and suddenly attacked him. The next day, Kazumi had no recollection of what she did to her husband and her fever was gone. For a while, Heihachi believed that Kazumi was suffering from a split personality disorder. But on one stormy night, his belief was proven incorrect.

While Heihachi was practicing his martial arts moves in the dojo, Kazumi confronted him and proclaimed that he would one day become a threat to the world. As they fought, Kazumi revealed to Heihachi about her reason why she married him in the first place. Her family, the Hachijo Clan wanted to kill him and this was her destiny as she finally assumed in her devil form. After a long and grueling fight, Kazumi attempted to kill Heihachi with a Devil's Beam but missed, prompting her to punch him in the face. But Heihachi retaliated by hitting her groin with a powerful uppercut, seemingly killing her while she reverted back to her human form. After Heihachi checked upon her body and turned to leave, Kazumi transformed into her devil form again to attack him from behind but he grabbed her neck. Desperate, Kazumi warned her husband about the chain of hatred and begged him to release her because of their love with one another. Despite her pleas, Heihachi noticed it was a trap and stated to her that she was no longer the Kazumi that he knew as he immediately snapped her neck, killing her. As Kazumi lay dead on the floor, Heihachi shed a single tear over the loss of his wife. Her death also leads her son, Kazuya to take revenge against Heihachi for killing his mother.
