Who is Graushaila

Who is Graushaila?

Graushaila, otherwise known as Dynast or simply, Ha-ou(Supreme King) takes form of a young man, whose features are younger than Gourry's or Zelgadiss'; probably a 15-yr. old; but definitely not a kid's face. They say that a mazoku can change form into a human and the way it will look will depend on its power. In other words, a weakling would have an unpleasant appearance and the strong would have the pleasant appearance anyone would like to see.
Anyway, back to Graushaila, he resides at North Foothold near Dragon's Peak. It's a cold place...really cold; definitely fit for a Mazoku with the coldest heart ever. He's reputed as the most ruthless, morbid, serious and smartest of the 5 Dark Leaders of Ruby Eye.
Now take this: how can a handsome mazoku like him have such an ugly, ridiculous-looking demon form: a huge BLOB-like creature. Take note: BLOB! Makes me wanna laugh though...
He appears in the novels but got defeated by Lina & co. He didn't get ruined nor killed but was seriously injured and had to retreat.
Graushaila has 3 minions: a general named Shaila and 2 priests named Grau & Grou. From their names, you can conclude several things about the way he thinks, two of which are: (1) He gives bad names; and (2) He must be dumb in naming minions.
Well, I guess that's it...

Who is Shaila?

Shaila is Graushaila's general. Once a human, he turned her into a demon when she died. She has blue hair and green eyes. She has this demon-sword called Doolgofa and if you get injured by this sword, you turn into a Lesser Demon.
Shaila has a very poised and serious nature which really makes her a great general anyone could ever have. She is also very loyal and devoted to her master, Graushaila; saving or defending for him his honor, grace and reputation. She hates it when people insult her master and ends up getting pissed at everyone but him.
She's also good in disguising(not to mention, acting!) as demonstrated in the novels: she was dressed in human clothes and was able to deceive Lina. Cool girl, huh?
