Lunch is Muten-Roshi's house maid, retrieved by the young Goku and Krilin in order to receive martial-arts training from him (his requirement was to "bring him a pretty girl").

She has dissociative identity disorder; whenever she sneezes, she switches between a sweet, innocent girl with blue hair, and a cleavage-bearing blonde bombshell who commits crimes for fun and is quick to respond with gunfire when angered (pulling a machine-gun out from nowhere when needed). Neither of Lunch's personalities remembers what the other says or does, and it is never said if the evil side knows of the innocent self; however, the innocent Lunch is aware of her evil side, although she doesn't really seem very concerned over her presence.
