Launch is a Yandere to Ten Shin Han from the anime Dragon Ball.
She is a woman with a strange disorder which causes her to switch between two different personalities each time she sneezes. Her first personality is a sweet, blue haired woman, who is pure-hearted. Her other personality is an angry, trigger-happy, blonde haired woman, who commits crimes for money and is quick to respond with gunfire when angered. Neither of Launch's personalities remembers the other's actions, or anything they said. Her blood type is AB. Tenshinhan to fall in love is when your yandere side comes out (of course in your state bad).
