Captain Gordon of the Earth Defense Force scoop up Laharl, Etna and Flonne and challenge the prince to a battle. Laharl recovers the Demon Tomb, and just as he harnesses its power, an airship materializes, threatening to destroy the Netherworld!
Would someone please tell me
what this "Demon Tome" is?
هل يمكن لأحدكم أن يخبرني 
ما هو "مجلد الشيطان" هذا؟
