It had been a few weeks after he met his mom and his younger sister, and Jack had been hard at work training his close combat skills. Along with learning how to use his fist and claws effectively, he'd also been learning how to use a multitude of guns.

According to his trainer, who also happened to be Zoe, he had an unnatural talent in both close quarters combat and marksmanship, this was attributed to both his lineage as a vampire and because he seemed to be inherently talented towards these things when he was a human.

Some more interesting things Jack had found out today would be that Zoe was a half-human. Her Mother was a Human while her Father was a Draconian, this mix of genes led to her becoming incredibly powerful, powerful enough in fact to throw Jack's 6"6, 265Ibs figure around like it was nothing more than a thin twig.

"Ahhh!"

As Jack was thrown into yet another wall by Zoe he let out a scream. His body was in tatters but it started healing as soon as he hit the floor.

After he healed, which was incredibly quickly, he stood back up with a helpless look on his face as he spoke towards Zoe, "Come on, Zoe, I know I have a healing factor and all that but it still hurts when you break most of my ribs and then throw me into a wall!"

As she heard this she giggled and stuck her tongue out at him and this signaled the end of their training session.

These past few weeks Jack had gone through such intense training and fighting that he had gone all the way to the peak of his current rank, E-Rank. He wanted to break through into D-Rank but Zoe warned him to not push too far too quickly in case he mutates too heavily and becomes a mindless monster. So in the end, Jack decided to wait until she gave him to affirmative; she knew more about this stuff anyway.

Anyway, his rapid increase in strength was because of his own efforts and because of the amount of blood he'd ingested, to put it lightly he'd been drinking 5 times more bloody than necessary a day.

While he didn't need to have this many - he only had to have one or two pints of blood per day - the more blood he drank the faster he recovered and the stronger he became. So, Jack drank as much as he could.

Over the past few weeks, he'd been training in a few martial arts which were: Taekwondo, Muay Thai, Krav Maga and the MCMAP used by the Marine Corps. He'd reached a level that would shock master level practitioners of these martial arts if they knew how fast Jack had learned and progressed through these Martial Arts.

Zoe described 5 levels that were the so-called realms of these martial arts which were Novice, Apprentice, Adept, Expert, and Master. Jack had reached Apprentice in all of the martial arts which showed just how immense his talent was when it would take a normal human a few years to normally reach the level he had.

He had implemented his claws into these styles of fighting as well, meaning he could also use these martial arts when he's in his Feral Form.

Onto his other lessons, mainly his lessons regarding learning Japanese.

He'd learned to read the language quite quickly, this was expected by Zoe as apparently Vampires naturally learn things quite quickly, one of their many talents as she put it. When it came to speaking the language he was getting there, he could understand it fully but he wasn't quite completely fluent in it yet but he was good enough in it that Japanese people should be able to tell what he was saying.

Jack looked at Zoe as he grumbled: "So we're going to Japan tomorrow, huh?"

Hearing his question, Zoe nodded without looking at him as they both walked towards the canteen.

Jack found out that he could also eat normal food but for some reason, he couldn't drink normal liquids. His past favorite drink, Orange Juice, tasted like shit to him now and when he forced himself to swallow it he threw it straight back up as soon as it hit his stomach. So now whenever he had food, he'd wash it down we a blood bag.

'Man, I must just scream 'I'm a vampire' Welp, not much I can do about it.'

As he and Zoe sat down and ate their meal, Zoe suddenly spoke up, "Jack, we need to have you go see our Psychiatrist," seeing his worry, Zoe quickly consoled him, "Don't worry, it's just protocol for when Agents leave to go on a mission."

Jack let out a breath of relief and simply nodded before carrying on with eating and drinking.

Soon after he and Zoe were done, they walked to where this psychiatrist was. Soon he entered and saw a petite woman with purple hair and red eyes sitting at a desk.

"Hello Jack, have a seat. I only want to ask a few questions, you'll be out before you know it."

"Alright Doc, do what you need to do."

Zoe waited outside while the questions went on. About 15 minutes past before Jack walked out of the office.

As soon as he walked out, Zoe told him to wait there and she walked in to have a chat with the psychiatrist.

POV Change - Zoe

"So, how's it looking Dr. Vrak?"

Hearing her question, Dr. Vrak showed a troubled face before she asked a question, "Where did you find this boy? He's incredibly unstable!"

Zoe grimaced slightly before carefully answering her, "I know Doc, but he's gotten better. And he won't be able to do anything too bad because I'll be with him most of the time and I can easily stop him."

Hearing what Zoe said, Dr. Vrak visibly relaxed, but only slightly, "As a psychiatrist, I can't exactly let him go into the field can I?" her worried frown slowly changed into a mischievous smirk, "But as a Demon, I wish for him to go into the field and cause chaos. Oh, how I am torn~"

"Well, he wouldn't be the most insane one you've ever let through into the field, would he?"

Conceding to what Zoe said, the Demon shook her head and let out a dramatic sigh and stamped on Jack's papers in a green stamped that said: "APPROVED".

"Bye-bye then Doc!~"

POV Change - Jack

2 days later~

Jack and Zoe were in their new house in Japan.

Jack had been briefed on his mission he had to complete while he was here. He had to be a rich young lady's bodyguard for her entire 2nd year at high school. Meaning Jack had to join the school as a 2nd-year high schooler and go to a Japanese high school for an entire year all while protecting this young lady.

As he was thinking this he couldn't help but rage a bit as he put some strength into his hand as he relentlessly hit the special-made sandbag. This carried on for another hour before he calmed down. He went to have a shower and when he came out he dried himself off and put some pants on and looked at himself in the mirror.

'How am I supposed to pass as a 2nd-year highschooler?!'

As he looked at his body, all he saw was perfectly carved muscle that looked like every inch of it pack immense power. His body gave off the sense of looking at an apex predators body, a body meant to kill and fight; not the body of a 16/17-year-old boy.

His aspect of the beast hadn't helped with this at all, as his Aspect was that of the Tiger, the apex predator, the king of the hill - How could his body be ordinary if he was meant to be the Apex?

Shaking his head, Jack looked at his pretty much perfect body he let out a laugh as he thought about how many girls he could possibly woo when he was both handsome, tall and had an incredibly well-built body.

'Well, Vampires are all known to be lady killers~'

As he chuckled at his joke he looked up at his face, he nodded at the changes Zoe had done the night before.

Knowing that his red eyes would attract a lot of attention, she gave him new blue eye contacts, as his last ones broke after his outburst when he had a reunion with his family. They decided they could leave his hair as it was because it didn't look too unnatural and if push came to shove he could just say he dyed it.

As he looked at himself, he finally did his hair right and slicked it back with only a few stubborn strands of hair falling down onto his forehead.

Today was the start of the year and Jack had to go to school and meet this young lady he had to protect.

After putting on his school uniform and making sure he'd put enough knives on his body (He stopped at 8), he packed some flasks of 'juice' into his bag and then ran towards the high school.

He soon arrived without breaking a sweat - perks of being a vampire - and went towards his classroom, 2-C.

When he was outside the door he opened it and entered a quiet room full of people who were looking at him.

He didn't know whether they were shocked because of his height, his hair and eye color or because of the fact even though he had clothes on, it didn't take much effort to see that he was incredibly muscular, but they were all looking at him like some kind of exotic beast.

He shook his head and walked towards the teacher. The teacher was a handsome looking man who was a bit on the short side but made up for it by being quite physically conditioned.

The teacher looked up at Jack, introduced himself with a smile as Mr. Hanagawa and pointed towards a seat near the back between two, quite frankly, very beautiful girls.

The one on the left was like Jack, she was definitely a foreigner, she had blonde hair and ice blue eyes, unlike Jack's royal blue eyes. The one on the right was definitely Japanese, she had short black hair in the style of a bob cut and black eyes that seemed to shine.

Jack sat down between them and they both turned to look at him, both for different reasons. The blonde girl because she had found someone like her whom she could relate to and the Japanese girl because she seemed to be very curious about Jack.

Jack ignored their stares as he thought about whom he had to protect, her name was Hanazawa Aya. He looked around and then finally he looked towards a girl sitting on the far side of the class and saw that she had a tag on her bag which said "Hanazawa Aya".

He knew this was the person he had to protect so he decided to introduce himself next time they were on break. The only disconcerting thing was that she kept looking over at him and death staring him.

'Oh god, she's one of those annoying Hime-sama kind of girls...'

As Jack was despairing, both the girls on the left and right of him seemed more and more curious about him as time passed on and Jack's problems grew with each second.
