Launch

Launch (ランチ) is a woman with a strange disorder which causes her to switch between two different personalities each time she sneezes. She appears as a sweet, blue haired woman, who is pure-hearted. But when she sneezes, she is an angry, trigger-happy, blonde haired woman, who commits crimes for money and is quick to respond with gunfire when angered. She does not remember her actions, or anything she said. In the Japanese version, her name is Lunch.
