Osoji is a Daimon Heart Snatcher created by Kaorinite to extract Pure Hearts. She has the appearance of a vacuum, as she was created from a vacuum that resembled an elephant. Her tail looks like a plug, and she can turn her arms into vacuums to create a suction to attack her enemies. She can also throw bags of dust at them. She appeared in Sailor Moon S Episode 5, Swept Off Her Feet.
Osoji extracted a Pure Heart from Andrew's sister Elizabeth, but lost it while being attacked by Sailor Uranus and Sailor Neptune. She found it in the junkyard and fought Sailor Uranus and Sailor Neptune, and Sailor Moon. She was winning until Tuxedo Mask hit her in the head with his rose attack, and Sailor Moon destroyed her with Moon Spiral Heart Attack.
