DD2 - Etna's 'Sexy Beam'
Disgaea Dimension 2 - Etna's 'Sexy Beam'
Etna appears in the game as a primary character(with Laharl and Flonne). Like Laharl her outfit has been changed too. This cosplay is about her unique skill 'Sexy Beam'.
2- 'Sexy Beam' Unique Skill
ps. Playful Succubus may have work better for the Tail and Wings, but the item is CLEARLY a reference to Etna, so I prefer to go for a more Original way... is VERY expensive too. ^ ^
