A bestial instinct driven Harry dashed at Kai, he had no speck of intelligence showing, his vampiric instincts weren't telling him that he was speaking to his sire and the progenitor of his race.
As he got within two metres of the vampire lord, the uncontrollable thirst that had taken over his mind exploded and took effect as he lunged at the goblet in the older vampire's hand.
Kai moved out of the way and ran at trackable speeds for Harry's sake, they ran outside of the castle and onto the quidditch field. Harry was right behind him, saliva dripping out of his mouth and his eyes were dilating. His appearance once again gained a more bestial look along with his long fangs, clawed hands and sinister glowing green eyes.
Kai watched as his son lunged and attacked him multiple times in an uncontrollable fit, he didn't manage to touch the hems of his trench coat but that didn't stop the boy from continuing.
His father could have easily shut him down and stopped him whenever he wanted to, but instead, he wanted to see the full extent of Harry's vampiric abilities as well as the true decline and sealing of his vampiric powers.
After letting Harry attack him for a couple of times he commanded his son to stop. "Stop," he said. The one word was filled with the majesty and power of the vampire progenitor as well as one of the most powerful beings in the world.
His son stopped his onslaught immediately, his instincts were screaming at him to bow down and submit to the being in front of him. His bloodlust disappeared immediately, just like the aura that had come out of Kai with his command and it vanished as soon as it came out.
After the vampire lord saw that his son's troublesome behaviour had stopped, he told him to breathe. His vampiric nature slowly returned into his body hidden from view and Harry's control.
Kai picked Harry up immediately and appeared in his new office, to Harry who was unaware of the extreme speeds that vampires usually moved at was shocked.
"I thought that you couldn't apparate in Hogwarts."
"Your thoughts are correct, you can't."
"So what did you do professor?"
"I did something all vampires can do. I ran."
"Your joking professor, if all vampires could move at such speeds then they would have won the war easily a long time ago."
"Before I explain Harry, it seems that you have not been educated on the vampire ways, as well as our individual talents."
"Yeah, I had some training with my godf-," he stopped. At the moment the wizarding world thought that Sirius was still the betrayer who gave away the location of James and Lilly Potter.
"So is your godfather a vampire Harry?"
"Huh, um yeah… he" Harry was very nervous that if he let something slip then Kai would call the aurors.
"Do not worry Harry, everything that is said in this room stays in this room."
"Well yes, he did help me better control myself better."
"If this is your improved control then I don't want to know how you were before. I swear that I was sure that there was a moment that you almost ripped off my manhood." His father joked.
"I'm sorry sir." He said guiltily.
"And that has brought me to the next subject that I wanted to speak to you about. I have noticed that you have not received any actual training from an authorized vampire. This is incredibly dangerous, you could cause extreme damage and even kill people if you aren't trained properly.
So I am offering you a chance to have private lessons with me and learn to control your vampiric nature. Would you like to receive my help?"
Harry looked at his professor with surprise at his offer. "I don't know sir, from what I have gathered from Hermione we have to study for our O.W.Ls and I was also offered some private lessons with professor Snape earlier today."
Kai looked at him, his eyes piercing into his own. They seemed to uncover all of his deepest secrets. "Are you sure, this is a great opportunity and most vampires would love to be in the position that you are in. I will let you think it over until our next lesson on Wednesday.
Just understand that if you do this then you won't only be doing this for yourself it will also be for your godfather, who hasn't received any real training either."
When Harry heard this, he seemed deep in thought before saying in the end, "alright I will take the lessons, but I will have to look at my timetable and tell you when I can."
They walked back to the hall in silence as Kai gave his son the goblet of blood, he didn't seem to want to drink the liquid lifeforce, but his instincts seemed to prevail, and he drank messily from the cup.
After he finished Kai cleaned the traces of blood from the boy's mouth and escorted him in. They entered the hall and returned to their seats.
As Kai sat down, he entered a state of deep thought, the professors that surrounded him seemed to want to ask him why he left with Harry but noticed that he was thinking and didn't disturb him.
He went over the information that he had discovered from his encounter with Harry.
The first was that Harry obviously had no control over himself, it could be because there was another vampire in the surroundings that caused the boy's own instincts to protect his sanctuary- Hogwarts. Vampires were known to be possessive of important and sentimental things that were close to themselves.
But even without his own presence in the mix, it didn't remove the fact that Harry's continued existence would cause the public's opinion of vampires to plummet even further and take the boy's own reputation with him.
Kai didn't care what they thought but he knew that it would be detrimental in the boy's memory recovery and acceptance of him.
The second was Sirius' poor upbringing of Harry, he didn't seem to know how to use his vampiric powers properly. And even if he did then it wouldn't affect Harry as he was a different type of vampire from Sirius.
Another issue was the fact that Harry's power had dwindled by a large margin compared to his original power. His current power was equivalent to a 3rd generation vampire native to this world. It caused Kai to be angered, Harry was his son and the very first vampire that he had turned.
He was a transcendent being, he possessed the ability to live forever and move at speeds that could easily decimate the wizarding community. But due to the powerful being that interfered with Harry and the rest of the world's memories, his power was limited by a large amount.
