A/N: Ignore my grammar mistake and enjoy.
If a human drink a vampire blood then the human will be cure from any illness.
If a vampire drink human blood then their lust for blood will be lessened in a limited time.
If a human get bitten by a vampire they will become a vampire as well but a level E that is mostly reconsider as a monster by both human and vampire. A creäture that can't be control and when it didn't drink the blood from the vampire that bites him then only death awaits. That's how life goes.
"W-why?"
Souma press his hand on the wound as he look up at the red-eye vampire.
"Why Takuma?"
He was afraid, scare and disgust. He thought Takuma is nice, friendly, possessive sometimes, caring but he never expect this.
"Souma . . . drink my blood."
Does Takuma want him as a possession?
"NO! STAY AWAY FROM ME!"
He starts to cry, even though his not the type to show weakness in front of others but this situation is an exception. He just got betray by someone he trust, it feels like he is experiencing the same thing as his mother.
Will anyone believe him if he says he and his mother got kidnap by a family of vampire and then they admit they were his step siblings that doesn't have any blood connection with him. They even think his stupid enough to believe he was one of them but maybe he is stupid to believe this kind of nonsense.
If only this is just a bad dream.
How does everything become like this, all he remember is that Senri from his class wants to apologize of what he says and asks to meet at the rooftop. He thought everything is just fine after that since he accept the apology and become friends but then things start to change.
"Your eyes are beautiful."
"Thanks, I guess I inherited it from my father."
"How's he like?"
"I don't know since I never meet him."
It feels like he has watched him all the time but he doesn't mind much since he is more powerful than kids in his class. He already proves it the other day about his strength. It's not like they have a power, right?
Anyway, he thought this is just a normal friendship like he has in his old school but . . .
"I want you."
Somehow he feels like he isn't looking at Senri anymore but why does he eyes and voice are different than usual.
"Senri?"
It was then the vampire pushes him on the floor.
"I want you all for myself."
"Huh?"
He start to struggle from him but find no accomplishment, their distance just gets closer when Senri seems to aim on his neck. He knows vampire drink blood and thinks it won't bring harm except for blood loss but his instinct is telling him something will happen if he let this man drink it so he quickly cover it with his hand.
"STOP IT!" He screams.
"If I don't this I can't mark you."
"You don't have to. Get off from me now!"
Why is Senri acting weird than usual? He is an emotionless bastard that get him in trouble in his first day of school and a guy who call him a puppet so when he turns to a scary molester that start touching his body freaks him out.
He starts to kick the vampire with his legs when Senri open his mouth wide showing those two pointy fangs.
"DON'T YOU FUCKING DARE VAMPIRE!"
'Stay away from vampire.' His mother words starts ringing inside his ear. 'You don't have to go to the same path as me.'
"What the hell are you doing to Souma, Senri?" Takuma appears beside them with his hand crosses and his eyes narrow.
"Oh . . ." Senri eyes turn back to normal before he move away looking confuse, he looks around before he stand up and walk away as if nothing happen just now.
Takuma stand there keeping his guard up as he watch his . . . cousin leave.
"What are you doing here Takuma?" He asks suddenly find the urge to asks.
"Saving your ass life before you gets bitten by him."
"I don't need your help."
"That's what your mom says all the time even though we know he needs it badly but as always pride is what matters to everyone."
"Don't talk about my mom like that! You make it sounds like you hate my mother and despise her!"
"Zero left us, left my father in his loneliness! How should I love him like I used to after what he has done?" Takuma shouts frighten the half human more than he intend to. "I hate the part of you that remind me of him."
"What's wrong for me to have some of my mother attitude? At least I'm not a wimp or a vampire since you guys are nothing more than a BLOODY SUCKING FUCKING VAMPIRE BASTARD! All of you should just die when you make contact with sunlight."
Takuma wonder why he starts acting like this. When he suddenly sees Senri on top of Souma make his blood start to boil and instead of masking his emotion like he usually do, his body act on its own and he rush to their side and stop them. Even in a billion years he won't let anyone else other than him to take the first bite on Souma neck.
Since the first bite is the eternal contract between the two sides. The one that got bitten will forever belongs to its master until the end of its life.
But . . .
Do you really want to be bitten?
"Ta-Takuma? Let go of my hand!"
No matter how much you scream, the predator won't hear you cries or prayer to be free from those eyes.
'Why? Isn't Takuma supposed to be the nicest between all of them so why is he doing this? Did I anger him too much?'
It didn't take long for everyone to know someone got bitten when the scent of blood is spread in an instant.
"Kain, isn't this . . ." Aido gulps.
"Takuma has bitten him."
"What should we do? Father never told us anything about turning him into a full vampire like us, we are in such a big trouble!"
"Calm down, dad rarely at home and he never been to our school so there's nothing to worry about." Kain says and look up. "We better use this chance to start planning on what we should do next, just as you say before we're in big trouble for not being there to control Takuma and keep leaving him alone with Souma."
"What's so special about him other that being half vampire and human?" He decides to ask.
"Well, Souma has the blood of the strongest vampire ever existed and the blood of the strongest hunter so you can say he has the power the kill us. The greatest weapon that our parents suddenly create even though his supposed to be the prove of coexistent between the two sides."
" . . ."
"He is also Takuma fiancé, to make sure Souma didn't go in a wrong hand father engage him with Takuma so he can be protected."
"Ah . . . I never know his that important and how come nobody tells me he is Takuma fiancé."
"You always slept when father tells us something important." Ruka shows up behind them with an angry look on her face. "Get off your ass from that chair, we need to clean some things and you Kain go and see Uncle Cross and let him handle the rest."
"Sure Madam."
"What is this sudden interest of yours in the new student Senri?" His childhood friend asks.
"Father wants to see him so I will just obey."
"And?"
". . ." Senri pauses before he continues. "His blood, there's something about it that seems so familiar. It's the same as Aunt Zero but a bit different."
"Are you talking about the Kuran blood?"
"No. . . It's actually more similar to me than them."
And for the first time in that girl life she sees a smile shown on the boy face. The amuse smile that have known something very interesting.
"Ta-Takuma." His voice is shaking as he can still feel his blood refuse to stop flowing out from his neck.
"You're mine now, right?"
It was then he passes out.
