Kasumi is probably DoA's most iconic character. The leader of the Mugen Tenshin clan, Kasumi was the main character of the first two games in the series.
She is a typical rush-down fighter that can create a lot of pressure in the close-quarters combat. One of the distinctions of her combos is the reliance on proper delaying, which, if done well, can empower any combo — or could ruin it if done wrong.
Kasumi is also very good at countering her opponents, and dealing critical stun blows in the process.
This trick can easily immobilize opponents, making her a significant threat in DoA 6.
