On the top we have L-sama . Below her we have Ruby-Eyed Shabrinigdo. Below him there are five dark lords. They are Hellmaster Phibrizzo, Chaos Dragon Lord Gaav, Greater Beast Zelas Metallium, Deep Sea Dolphin, and Dynast Gyasherra.
Each one has two more mazoku working under them a general and a preist. The exception to this being Zelas who only has one mazoku as her general and her preist that would be Xelloss. The power is usualy divided among two mazoku but in this case it is all given to one mazoku.Therefore he is the 6th most powerful. I've also heard that Dynast has 2 generals and 2 preists.
First dak lord: Hellmaster Phibrizzo.
Okay Hellmaster Phibrizzo (as inferred by his name) is the master of all nine hells. His human form is that of what looks to be a 10 or12 year old gir. . . ah . . . I mean boy. He uses these little things called soul orbs which look like little golden beads. What they do is when crushed they destroy whoevers soul they represent.
Second dark lord: Dragon Chaos Lord Gaav.
Gaav looks like a middle aged man with long red hair. His Mazoku form is a dragon of sorts(duh).
Third dark lord: Greater Beast Zelas Metalium.
Greater beast lives on Wolf Pack Island. It's not marked on any map.
Zelas' Mazoku form as far as I know is a wolf like beast of sorts. Her human form is that of a young blonde woman.Zelas is also known to be a heavy drinker and smoker.
Fourth dark lord: Deep Sea Dolphin.
Deep Sea is rumored to have been driven crazy by Greater Beast. That's about it.
Fifth dark lord.
I know absolutly nothing about Dynast.I'll be doing some research on him soon probably.
Then I suppose I should tell you about Ruby-eyed Shabrinigdo. Well he isn't pretty. Well He is called ruby-eyed for a reason he has red eyes. Shabrinigdo was split into seven pieces long ago. One piece was sealed iside the blind eyes of Rezo the red priest. This is the piece thet he released and that Lina fought and defeated using the giga slave. Do you know the words to the dragon slave? Darkness beyond twigloght, crimson beyond blood that flows, buried in the stream of time is where your power flows, I pledge myself to conquer all the fools who stand before the power that you and I posses. Those words are describing Shabrinigdo.
Well there is more to tell you but not much. Well mazoku feed on the negative emotions of humans. That's about it for now.
