Selling candy that made whoever ate it overweight and unhealthy and opening up a spa that would drain the energy out of the clients who went there.
deVleene was an agent of the Dark Agency.
deVleene had short curly hair. She wore a light-colored blouse with a bow and a heart, a black skirt with a heart stitched in the middle of it, and high heels. Her accessories include earrings and a hairband.
She introduced fattening candy called Rainbow Chocolates around Valentine's Day. She managed to fatten up a majority of the female population, and opened a spa which promised to help them lose weight, but it was only used to suck out the energy of her clients. She was later defeated by Sailor V's Sailor V Chop and Crescent Slender Beam.
