Zoycite sent Suzuran, Housenka, and Grape to kill Neflite. They kidnapped Molly, and Neflite came to save her. He beat them up, but instead of killing them, told them to tell Zoycite that they would not be getting his star crystal.
However, the plant sisters returned to kill Neflite. Before they could kill Molly, however, the Sailor Scouts appeared. After Sailor Mercury used Mercury Bubbles Blast, Sailor Moon and Sailor Mars used Moon Tiara Magic and Mars Fire Ignite, combining their attacks to destroy Suzuran, Grape, and Housenka.
In the Mixx Entertainment novels, the 3 "Plant Sisters" are known as the "Delta Girls".
Suzuran gets her name from the Japanese name of the Lily of the Valley variety of flower.
