Kasumi Todoh (藤堂香澄 Tōdō Kasumi) is a video game character in SNK Playmore's Art of Fighting 3.

Kasumi is the daughter of Ryuhaku Todoh (藤堂竜白 Tōdō Ryūhaku) from Japan. Her father was also playable in the original Art of Fighting game.

According to her official biography, Kasumi was born March 29, 1980. She stands 1.54 m (5 ft 1 in) and weighs 45 kg (99 lb). Her blood type is B. Her three sizes are 0.75 m (29.5 in), 0.54 m (21 in), and 0.74 m (29 in). Her hobby is watching movies, especially horror films. Her favorite food is beef croquettes given to her by the butcher on the way home from school. Her favorite sport is aikido. By the AOF timeline, she might be about 10 years older than what the official biography might claim.

Kasumi Todoh grew up learning the Todoh school of Aikido and Kobujutsu, induced to her by her father. As the single heir of the Todoh family, Kasumi has to do all she can to stand up to the family.

When Ryuhaku travelled to Southtown to settle an old score with a man named Takuma Sakazaki, Kasumi remained in her house, waiting for her father's return. A couple of months later, he came back with some bad news: he had been defeated by Ryo Sakazaki, Takuma's son.

Kasumi told her father to rest up, and let it all to her. She decided to fight Ryo and anybody else in order to avenge her father. Unfortunately enough, her mother, Shizuka, did not like that idea.

Kasumi went on to participate in the 1996 King of Fighters tournament with King and Mai Shiranui. After Leopold Goenitz (highest priest of the Orochi Power) was defeated (not to mention taking his own life), King took Mai and Kasumi to her bar.

In 1999, she not only reunited with King, but also teamed with Blue Mary and Li Xiangfei to try to stop NESTS. Later in 2000, Kasumi rejoined Mai, and the two teamed up with Yuri Sakazaki and Hinako Shijou. While Kasumi had some reservations about teaming up with Yuri (mainly because Yuri is a Kyokugenry Karate practitioner), Kasumi knows that she has to live under a family code of ethics and accepted Yuri as her teammate. This was a sign that Kasumi matured a little bit as time passed by.

Kasumi considers herself as a rival to Kyokugenryu Karate, but knows that in her heart, a code of ethics has to be followed, as she knows that she cannot foul her family's name. She respects all rivals, and will cooperate with other people's efforts to fight injustice at anytime. As opposed to Eiji Kisaragi (who totally hated Kyokugenryu Karate), Kasumi remains a gentle, kind rival to Kyokugenryu Karate, although she can be high-spirited and immature at times. Kasumi provided a lot of comic relief to Art of Fighting 3, in which she had to look up a translator to see which word in English she needed to say (because she didn't understand a word in English when she first ran into Ryo), though this appeared to not be an issue in KOF. Kasumi also appears as a playable character in SVC Chaos: SNK vs. Capcom and The King of Fighters R-2. Kasumi Todoh has always been voiced by Masae Yumi, who also did the voiceovers for Leona Heidern and Vice.
