Nemea

Nemea is a succubus fought in the collab The Night Country and the Heroes of the Seven Worlds. She comes from Succubus Prison: House of Lewd Demons with Myusca and Vinum. She's a cruel succubus that enjoys pampering young men to their death.

Biography
She is first briefly seen at the end of chapter 2 when Kazuya runs into her and Vinum. She's intrigued by the fact that they managed to escape Myusca.

She's properly introduced at the beginning of chapter 6, where she tells that she will enjoy eating down Hakunen before disappearing to suck dry more villagers.

The party later runs into Nemea again as the latter is draining a young boy to death, while telling them that he jumped to his demise of his own accord. Understanding that they're outclassed, the party is forced to escape.

The party meets her once again when they reach the entrance of the village while fleeing Vinum. The party fights her, and barely manage to hurt her when Vinum arrives behind them. Fortunately, they are saved by the intervention of Magatsu, Lauratt and Rigeo

Strategy
Just like Myusca, keep Defense song to limit her regeneration and song of Mahobora up to limit status effects and keep your party operationnal thanks to Dream Fox. She can also be stopped with Mukuro.

Using holy attacks is quite effective against her. Last, don't forget a loss can be replaced with the fifth party member in a pinch.
