After defeating the War Gods, Ren and his friends are living the dream. 
It seems like they've finally managed to regain their normal lives. However, a mysterious girl by the name of Pandora appears, bringing with her a box that must never be opened. 
An unfortunate incident results in the box opening (of course), setting the world up for some big changes...
No matter which way you cut it,

Pero eres un monstruo, ¿verdad?
Peu importe ton nom,

Independente de como você pinta a coisa,
você é um monstro, não é?
