Luverin (Japanese: ラブリン Loverine, サクラのラブカス Sakura's Lovecus) is a female Luvdisc that belonged to Misty's oldest sister, Daisy. She acquired her in the Kanto region, despite the fact that Luvdisc is not normally native to the area. The name is a play on both the name Catherine and ラブ love, which is also present in ラブカス Lovecus, Luvdisc's Japanese name. Her English voice actress is Rachael Lillis and her Japanese voice actress is 氷上恭子 Kyoko Hikami.
Daisy and Misty each obtained a Luvdisc of opposite genders, wanting to use them in one of the Cerulean Gym's water ballets. Misty's male Luvdisc, Caserin, was in love with Luverin, but Luverin ignored him.
In Luvdisc is a Most Splendored Thing, Dr. Namba of Team Rocket sent Butch and Cassidy to steal Caserin and Luverin as part of his twisted plan to rid the world of love (in the Japanese version, Namba just wanted the two Luvdisc captured for his R Project). His plans were ruined, however, when Luverin and Caserin managed to cooperate and save themselves. Seeing Caserin's heroic acts, Luverin fell in love with him.
