It's been years since the coup d'etat on Zoble, and the demons have managed to remain hidden for that entire time, as the Idaten fruitlessly search for them. But when Miku springs her plan to rendezvous with the Demon Lord, all that is about to change.
It's the same as when 
people spend their lives
هذا لا يختلف عن النّاس الّذين يقضون حياتهم
Wie Leute, die aus Angst vor Versagen
gar nichts mehr machen.
È lo stesso errore che si fa quando si vive
senza fare nulla per timore di sbagliare.
É o mesmo tipo de erro que
as pessoas fazem quando
Такая же глупость, как ничего не делать в жизни
из-за страха неудачи.
