Vampire Demon Lord

"How will the elves blood taste" I thought while licking my lips.
Ronal was a university student but he was very unlucky no matter who he worshiped, he always gets beaten up, he always loses his chance at important things, he loses his money in bets, fails his exam even after studying hard and 1000 more things.
One day he decided to summon a demon but he did not know that it would be successful and instead of a regular demon he summoned the fallen angel Lucifer.
.
.
"You are the best candidate to take the next demon Lord position after me" Lucifer said.

"Me!" Ronal exclaimed while sweating.

But before he can get his answer Lucifer stabs his hand in Ronal's chest and kills him.
