Kei is one of the protagonists of the Dirty Pair series. A hot-headed tomboy, she is part of the Lovely Angels with her teammate Yuri. She has red hair, tanned skin, brown eyes, and often wears a silver-white uniform (light purple in Affair of Nolandia). She favours large weaponry and has a "shoot first, ask questions later" attitude.

Kei is the more outgoing of the Lovely Angels. Her fierce red hair matches her temper, and woe betide the person who faces her wrath. She is highly motivated and will often move forward, sometimes, regardless of the consequences. Kei is an expert shot and is highly skilled in unarmed combat. Kei has apparently dated a number of men. However, despite her evident charms, she has not managed to gain a steady relationship.
