Kazumi Mishima, wife of Heihachi Mishima, is well versed in Hachijyo Karate. She was childhood friends with her husband Heihachi and eventually they fell in love. Through their love they birthed a healthy young boy. Fast forward a few years later, Heihachi would become the head of a huge organization called the Mishima Zaibatsu, with plans to conquer the world. Kazumi loved Heihachi unconditionally, but at the same time he was beginning to feel dangerous. In this state, Heihachi threw the world into a war and Kazumi took it upon herself to stop him. Kazumi's fighting style is Hachijou-Style Karate, but mixes with Mishima-Style Karate. She utilizes a strong combination of the two styles, to the degree she was a threat to Heihachi in his prime [1]. In Kazumi's promotional art, her appearance resembles that of a white Japanese empress. Kazumi is a very beautiful woman, she has a long black hair with a full fringe and is tied in a large Japanese bun and brown eyes. She also has a mole on her bottom right eye. She wears a white short sleeved traditional kimono dress with a red rope tied in each side of her shoulders and a red ribbon attached on the back on her shirt which is connected to the red rope and a gray diamond designed obi which is tucked into her kimono dress. She has an off-white traditional kimono dress which is tied in a white karate belt on her waist and both sleeves of the kimono dress are hanging loose with flower designs in her sleeves and her skirt of her dress. She also wears a white and red fingerless gauntlets with a golden shell design tied in red ribbons in each side underneath her arm and wrists. The interior of her off-white kimono dress is red. She also wears white tabi which is tied in red ribbons and traditional Japanese geta. She also has a Mishima Zaibatsu insignia at the center of her waist while wearing the outfit. At the back of her hair which is just above the nape, she wears a kanzashi shaped like a gold phoenix.

During her transformation to Devil Kazumi, her kanzashi can be seen and heard falling off after she was struck with a lightning strike while she was down on her knees and being engulfed with a white haze. It's possible that her kanzashi acts as a limiter device to restrain her Devil Gene. In one of the Heihachi's flashbacks, she wears the same traditional kimono dress as in her current attire as her fringes on her hair is parted on the right side. Also in one of Heihachi's flashbacks after she gives birth to her son, Kazuya and shows it to her husband in both scenes, Kazumi wears a white short sleeve martial arts gi with a black belt which tucked into her gi, a matching martial arts pants and white sandals. Her long black hair is tied in a low ponytail at the right side. Kazumi has a combination between both Heihachi and Kazuya's moves as she gains both their Demon Slayer and Flash Punch Combo. Her own moves include vicious punches and strikes, and another skill where she flurries her opponent with several punches as well as knocking her opponent with both a roundhouse kick and a straight kick. Her unique ability is to summon her pet tiger which can be done during a combo or individually, it is also seen after Kazumi performs an uppercut along with her tiger. She shares her ex-husband's Hell Axle but has an additional downward kick and his unblockable move but it's not as strong as his. She also has a taunt where she calmly pets her tiger during the fight. Kazumi's (and Devil Kazumi's) Rage Art move involves stunning her opponent with a single punch to the gut, knocking him/her with an uppercut, unleashing a single punch and a kick with two consecutive punches followed with another kick in mid-air and finally slamming the opponent with a heavy blow on his/her chest before landing on the ground [2].
