Etna

Etna is a bonus character in Makai Kingdom the player can recruit after completing at least one story cycle.

Recruitment
To fight Etna, a wish titled "I wish to see the ending!" must be granted in the Sacred Tome. The wish is unlocked on the players second playthrough with at least one unit at level 80 with 4000 Mana for the price of the wish during any episode.

Though, to actually recruit Flonne, a wish titled "I wish to an Overlord!" must be granted. In this battle she appears alongside Laharl and Flonne, though only Laharl must be defeated to clear the map.
