Etna is the leader of the Prinny squad and one of the few vassals who remains by Laharl's side after King Krichevskoy's death in Disgaea: Hour of Darkness. After reviving Laharl through interesting means, Etna accompanies Larhal on his quest to reclaim his throne. Although not trustworthy and manipulative, she becomes Laharl's closest vassal and joins him on the battlefield.
Etna often acts carefree and snarky towards Laharl and Flonne, but she always has alternative motives and is usually plotting somthing in secret. She likes to spend her time abusing her Prinny squad and has a deep respect and loyalty towards King Krichevskoy, Laharl's father.
In an alternate story, Etna Mode, available on the PSP and DS versions, Etna kills Laharl by accident when waking him up. In order to prevent suspicion from Maderas, Etna places fake antennas on a Prinny and passes it off as Laharl.
She also appears as a playable character in many other Nippon Ichi Software games, including most of the Disgaea games.
