In front of a foe that is lethal to one, what could be the biggest mistake that one can make?
Though many things could be counted, there is one specific thing that is the most important.
'Keeping your calm.'
A calm mind and coldness bring the best results when a plan is made. Those who operate with their emotions are unstable beings and can never climb the ranks of power.
There was a reason why this count needed to seal himself under the ground. It was because he couldn't control his urges and attacked his servants, revealing to the world that he was an enemy.
If he was able to control himself and utilize the power his position held, he would be one of the most dangerous beings in this world.
But he couldn't.
Therefore, I knew for a fact that this vampire before me wasn't someone who was coolheaded, and I was going to use this to my advantage.
