Flonne is an Angel Trainee from Celestia who was sent to the Netherworld by Seraph Lamington to assassinate King Krichevskoy. Unfortunately, she arrives to find that the king has been dead for two years. With no reason to return quickly, she decides to join Laharl's quest to reclaim his throne in order to learn whether or not demons are truly as evil as Celestians claim them to be.
Innocent and naive, Flonne has quality traits of an otaku and ditz. She is deeply devoted to both Seraph Lamington and the concept of "love," earning her the title of "Love Freak" from Laharl.
She appears in many other Nippon Ichi Software games, including those in the Disgaea series.
