Setsu Suzaki and his classmates are suddenly summoned to a foreign world, and arrives at a kingdom that is just about to plunge itself into war. Most of the children are confused, except for Setsu, because this isn't his first time.
We should never have struck 
peace with the demons!
!لم يكن علينا الدخول في السلم مع الشياطين
No debimos haber firmado la paz
con los demonios.
No debimos haber firmado la paz
con los demonios.
Nous n’aurions jamais dû
coopérer avec eux.
हमें शैतानों के साथ कभी भी
शांति के लिए नहीं टकराना चाहिए था!
Non avremmo mai dovuto siglare la pace coi demoni!
Não deveríamos ter ficado
em paz com os demônios!
Зря мы вообще заключали мир с демонами.
