Lum's childhood friend Ran comes to Earth, but she's here to seek revenge on Lum for all times that Lum got her in trouble when they were both little. She also tries to suck out Ataru's youth by kissing him.
Did You Know?
I'm going to stay on Earth and hide the fact that I'm an alien until after my revenge is completed. And if you reveal what I really am, I'll tell everyone about the time you stayed at my house and wet my bed!
