Because I Am a Monster.

"How?! How are you alive?" Tero sounded more angry than surprised.

"Heh! Like cutting my neck could ever kill me" Denis took out several injections from his overcoat pockets-- that were filled with black liquid inside them. "Because of this thing."

"That.." Luka's eyes widened as his body started trembling. "Why...do you have it?" Luka muttered

"Lu...ka?" Tero tried to call Luka.

"Why do you have it?!" Luka yelled

"I joined the school to scout some strong exorcists from the potential. And I did, but…" Denis sighed. "None of them could be useless, so I had to kill them."

Luka was trembling as though it was his body-- not Luka himself.

"And in this batch, there are some exorcists with potential. The first one is Ana Bismarc, second is Liz Earl, third is Nishetre Billionere, fourth is Seig Hams, fifth was you-- Luka Aldini, then Tero was on the list too, and many more students."

Denis looked at the injections and pointed them at Luka, "I was supposed to inject it to you and Tero so that you could join us."

Denis then smirked, "And this is a perfect chance" He laughed out loud. "Master will be happy today!"

"You are a monster!" Luka said with a voice filled with rage.

"Monster, you say?" Denis pointed his finger at Luka and said with an emotionless voice, "You are more of a monster than me, Luka."

"What are you talking about?"

"I honestly have no idea," Denis shrugged his shoulders and continued, "But my master has taken quite liking to you, and he wants to add you and Tero to his collection."

"I asked…" Luka muttered, then roared, "What the hell are you talking about?!"

"Why so angry?" Denis scoffed then said, "I will tell you everything--- if you take this injection."

"Exorcist council will track you down and kill you," Luka threatened.

"Shut up-- you dog of the council!" Denis raised his voice and said with a glare in his eyes, "Why do you even follow the council? Don't you know they were the ones who hunted down your real father?"

"You knew my father?"

"That's right. He was hunted by exorcists." Denis reached his hands towards Luka, "Come join us and take revenge on the council!"

Luka's brain stopped working. He was already aware that the exorcist council had killed his real father-- though he didn't know the reason. Deep down, he always wanted to know the reason. He wanted to know who he was and why all that happened.

'If you come back before night, I will give you a kiss. So come back as soon as possible, okay?' Suddenly, Ana's voice rang inside Luka's mind, and it brought Luka back to his senses.

"Don't let him get to you, Luka!" Tero warned Luka. "Don't listen to him!"

Denis was too fast for naked eyes to see. "Too late" The moment Luka looked at Tero, Denis had already injected three injections in Luka's body.

"Luka!" Tero yelled

Luka bent down and started scratching on the spot where Denis injected him.

"Argh!" Luka grunted in pain. "It burns! It burns!"

The spots where Denis injected turned black as the impurities started spreading inside Luka's body, and strange marks appeared. His veins and nerves started popping, and his body was turning black.

That was the sign of getting infected.

When a person gets infected by any impurities, the impurities first attack the brain and infect all the memories. Once the brain is infected, the impurities spread further and further when there is no resistance in the body. The blood burns out, and all the organs inside the body melt and gets ruptured.

That was the worst way to die for any human or exorcists.

"Luka!" Tero yelled, then glared at Denis and dashed at him, "Denis, you bastard! I will kill you!"

Tero tried to attack Denis, but Denis dodged him and kicked him on the back-- Tero slammed into a tree.

"You are no match for me." Denis' speed and strength was far more than an S-rank monster.

"Brff!" Tero coughed out some more blood. He was already injured from Denis' attacks earlier, and the second attack almost made him lose his consciousness.

Denis slowly walked to Tero while saying, "My master did say that he wants both you and Luka. I already got Luka, but you..." He frowned his face and glared at Tero, "I really don't like you."

"I will… kill… you." Tero was already feeling dizzy.

"That's right," Denis snapped as if he had got a brilliant idea," I will kill you and tell my leader that you died while resisting."

"Not gonna happen" Luka stood up and grabbed Denis' head with his hair.

"How are you fine with that much dose of impurity? No one should be able to--"

"Because I am a monster." Luka kicked Denis on his back while grabbing his hair and pulled Denis' neck as his body fell to the ground.

Luka tossed Denis' head in the air and slashed it until it reduced to nothing.

Luka then looked at the headless body of Denis and stabbed it a couple of times. "Now it's finally over,"

"Yeah," Tero stood up. "It's over."

"But what is going on?" Luka checked himself and asked, "How am I okay?"

Luka still had some marks on his body, but they eventually disappeared, and there was no sign of infection--anywhere in his body.
