Princess Syalis is abducted from her home of the Nation of Goodereste by Twilight the Demon King. Despite the horrors lurking in the Demon Castle, all Princess Syalis wants is a good night’s sleep.
Once, in times when humans
and demons mingled and coexisted...
...في قديم الزمان، عندما كان البشر متعايشين مع الوحوش
Früher gab es eine Zeit, in der
Menschen und Dämonen koexistierten.
Alguna vez, cuando humanos y demonios
convivían y se mezclaban,
Il y a fort longtemps,
les humains et les démons
Molto tempo fa, in un'era in cui esseri umani
 e demoni convivevano pacificamente,
Era uma vez, num tempo em que humanos
e demônios se misturavam e coexistiam,
Некогда люди и демоны сосуществовали, 
дружили и роднились между собой.
