Karin is from the wealthy Kanzuki family
(daughter of Daigenjyuro and Nadeshiko Kanzuki), whose motto is "All you
need is victory".
Karin considers herself
a rival of Sakura,
whom she was defeated by when challenged. Karin uses the martial art of
Kanzuki-ryu kakutojutsu (which is based on Chinese Kenpo). Karin made her first
appearance in the 1996 Street Fighter manga Sakura Ganbaru! by
Masahiko Nakahira. Later in 1998, she made her fighting game debut in Street
Fighter Alpha 3.
During the timeline of SFA3, the Kanzuki corporation is threatened by Shadaloo, which then makes
demands of the dynasty. Karin uses the family fortune when attempting to track
down Shadaloo as well as a roving Sakura to challenge her again. Along the way,
she encounters Blanka
and defeats him in a friendly match, musing that "the world is so
vast" for such a beast to exist. She also encounters R.
Mika and battles her, and is so impressed by Mika's ability that she offers
the wrestler her sponsorship. Karin eventually finds and defeats Sakura, but
realizes the victory was a fluke, and that the fight itself is more important,
not winning or losing (Ken
Masters told her this previously). She lives by her motto more than the rest
of her family, as she takes majority control of her father's company from under
his nose in a hostile takeover (ironic since he was the one to drive that
philosophy into her). Her family's estate covers 200 miles of land, and not only
has its own geographical features, but its own climate.
Karin's butler, Ishizaki,
appears in her win poses. Ishizaki is a pudgy but engaging middle-aged Japanese
man with burly arms and a warm, welcoming smile. He is always willing to do what
Karin wishes of him, though sometimes he wants to get in on the action and do
battle. In addition, Ishizaki was assigned the job of baby-sitting/watching over
Karin while she traveled the world, in search of a rematch with Sakura. Since he
and her have such a close albeit rocky bond, he can be considered to be her
closest friend in the Kanzuki mansion, as he is very proud of her and takes such
good care of her.
