7 Prince Of Hell

I Immediately noticed the title and this is the book that Haru picked up from that horse carriage. And if I remember correctly, this book is at the power of a dragon rank magic knight, it's kinda hard to imagine that this book has more magic that Lios himself. " What about that book? ", I asked, Auntie Put it on her thighs and put both of her hands on top of it, " This is a demonic book, I've stole this from the Demon Kingdom from the South " You've stole that book?!, " but wait, thought this was just a diary? ", I asked, She open the book and flip the chapters, " I'll show you the page but don't ready the words no matter what ", Then what's the point of seeing it?!, " Here ", Auntie Elizabeth showed me the page, and the first thing that caught my eye, was the ink image on the page, a man, with long hair and muscular build but most of all he has two long horn pointing upwards. " That is man on the page is named asmodeus, He's the demon of lust and one of the 7 prince of hell ", Damn, that information is so heavy. But I do remember calling out for his name when I'm casting my spell, what does that mean?.
