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...
But this Pandora's Box I took from
my Grandpa is extremely dangerous.

die ich meinem Großvater fortnahm,

que robé a mi abuelo es muy peligrosa.
Pero la Caja de Pandora que le robé

Mais la boîte de Pandore que j’ai prise
à mon grand-père est très dangereuse.
Mas esta Caixa de Pandora que eu peguei
do meu avô é extremamente perigosa.
