The Main: Flashback

Dear, Robin-chan

This semester I don't plan to go home. Yeah, rather than having to meet the moss head dog, of course I'd rather spend my vacation with my girlfriend, right? She isn't an ordinary human, although she hides it, I know she is a vampire slayer. Mellorine... sure my relationship with her will be much hotter than you and the dog. Yes, she comes with a secret objection. I've ever told you when we met last winter that there's another vampire infiltrating my school. Well, she suspects me, mellorine, I'm even more attracted.

Okay, I'm deadly serious. I love her, Robin-chan. Honestly, I want to keep her away from that shitty lion faced-vampire but I certainly can't take her to your place, right? If only our vampire law didn't forbid us to interfere with other vampire's dinner event, the story would be different because I was the one who went to his territory since he was staying longer there. However, if I end up breaking it, I won't regret it. Like you.

Hope you always stay healthy, Robin-chan. My middle finger is sent to greet your pet.

Sanji

"I'll crack your bones, Ero-Leech!" Zoro responded as Robin read the letter afterward. "I want to crush you now."

"Fufufu, so you want him to go home," a female vampire named Robin teased him.

"Of course not!" Zoro shouted. "And how idiot he is having a relationship with a vampire slayer."

"Are you upset if they will be hotter than us?"

"N-nope!" And so a little red tinge appeared on Zoro's cheek.

Hot. Yes, a cold-blooded vampire. Werewolf and hot-blooded humans. Although it was initially a taboo to connect with them, vampires sometimes couldn't refuse if they came in contact with them so deeply. They are more emotional, they are more expressive, while the vampires are too rigid in feeling love to the opposite sex of their fellow until they also experience reproductive difficulties because their hormones are so low.

In general, vampires do prefer to connect with humans. There are some vampires who 'nurture' humans to be donors, that as long as not draining it in once suction, human blood cells will continue to produce again, like symbiotic mutualism because there are still many who don't get the knowledge that the actual human who often donates blood make their body metabolism becomes smooth and the function of blood to be better so as to make the donor be healthy. It's just that the sensation given through the syringes in the arm compared to the fangs of vampires in the neck is very different. Vampire's saliva that goes into the blood circulation like drugs, makes you want to ask again. And in some cases, its passion was like an intercourse so half-blood vampires and the descendants are born. And so humans will become entangled in the power of the vampire. Moreover, werewolf is like an enemy under the blanket for most vampires and their nature is too different: Too contrast, too hot. They have long been in the cold war for centuries, while humans themselves are still many who don't recognize the existence of those two-night creatures.

And, this time why Sanji sure that his relationship will be hotter? While werewolves could eat any animal flesh as carnivore, human's blood for vampires is a must. That's why vampires have new enemies that are more frontal hereafter. Human rebellion. Human beings who fight for the rights of their human's life. Yeah, they are Vampire Exterminator, within the organization led by Monkey D. Dragon.

Sanji was close to Robin, even when she decided to quit from Central Coven for secretly establishing a relationship with a werewolf named Zoro, Sanji was still following her. In a way, he's very anti with the werewolf and he wanted to keep Robin safe, worried if one of the ladies he dearly loves gets unpleasant deed. As for Robin, Sanji is like her little brother. She did not feel bothered and smiled amusingly every time she saw Sanji and Zoro fight. For her, the quarrel never got to the point of seriousness and she considered it a form of intimacy that could make Sanji rethink about werewolf that they aren't as bad as vampire commonly perceive.

"Curly Brows!"

"Moss Head!"

"Ero-Leech!"

"Shitty Dog!"

That's how Robin enjoyed her days with them.

The three of them lived long enough until Sanji decided to break away, not wanting to disturb Robin's household again and perhaps already tired of quarreling with Zoro. He said he wanted to go in adventure looking for beautiful human girls. Yes, he didn't want to go back to his Coven, Germa, as he's arranged to marry a daughter of a high-status vampire family to extend their politic power. He wanted to go to the human school especially the one having dormitory facility, switching school every three years as he graduates. After all, vampires have a long time of their life, studying at school 5-6 times is still felt short for him especially his structure always young like teenager. He knows that vampires claim their people are intelligent (especially his family) but just like Robin, he also argued that humans have a wider knowledge than vampire because vampires are too proud of themselves, they will be surpassed by human science and technology. That's the result of living too long and not aware of the changing era. Nah, when school has a holiday, Sanji always come home to share his knowledge to Robin.

And the letter Robin read was dated 3 months ago.

Until one day, three unwanted people knocked on Robin's door ...

"Rob Lucci!" Robin cried out. She also saw two other vampires behind him, a wavy blond woman wearing glasses, and another square-shaped nose. "Why are you here?"

"Oi, Robin!" Zoro was also not happy with the presence of the three uninvited guests. "Who the hell are they?"

"They're official vampire officers, Mariejois Central Coven's representatives," Robin replied uneasily.

"Your greeting to the guests is not very friendly," said Rob Lucci smiling. Then, he looked at Zoro. "We're not in a fight with a werewolf who has defeated one of the most respected vampires. We still have brains to avoid the bloodshed even though we came three of us. Nevertheless, we already know that your reason for escaping from Central Coven isn't because you have a relationship with him. "

Robin's heart was beating fast. So they finally know it, she thought.

"You keep a 900-year-old ancient literature of vampire history that should have been erased. It's about the existence of Diable. You think we're not watching you, the Demon Child of Ohara? " Rob Lucci continued.

"So you're going to get me to Coven court now?" Robin asked. Meanwhile, Zoro didn't really understand the meaning of their conversation. But if they did want to take Robin away, he was ready to rage.

"No," Rob Lucci replied. "We want to give you a chance to atone and after that's done, we won't bother your life anymore."

"What's that?" She honestly didn't trust them.

"You must have shared the information in the literature with other vampires."

Sanji, Robin thought.

"And according to the latest news, a month ago the demon has risen again. You have to be responsible, Nico Robin. "

It can't be, Robin thought again. Sanji don't...

"We're not lying," a box-nosed vampire named Kaku cutting Robin's mind. "We have this note ready to prove it to you."

Then a female vampire named Kalifa threw a paper roll right in front of Robin's feet.

"Actually we want to let Vampire Slayer react first because it can reduce their numbers without them bothering us to intervene. But it should not be taken too long because other vampires will know this secret history. So we give you 6 months to fix it."

"Do you want Robin to kill each other with that demon?" Zoro interrupted brooding Robin dismissed. "Hmph, picking up two defendants at once, so cunning."

The three vampires laughed.

"What the hell are you laughing at!" Zoro exclaimed annoyingly because there is nothing funny.

"That's precisely why we gave her this chance," Rob Lucci replied.

"Yes, the key is on you," Kaku pointed at Zoro.

"Just ask her, the only way to kill demon," Kalifa continued.

"W-What?" Zoro glared at them. Then his eyes moved on to Robin.

"Werewolf's paws ..," Robin said rather quietly. "Werewolf's fangs and nails, that's all that can hurt the demon's flesh skin to penetrate into its heart."

M-Me? Zoro thought.

"Surely it doesn't matter to you who has ever defeated a vampire, do you? Isn't defeating a demon a bigger challenge?" Rob Lucci asked Zoro.

"Yeah, if you really want to save your woman from the burning sun execution in Enies Lobby at 12 noon, that's the only way," Kaku continued.

"If you don't want it too," Kalifa said sarcastically. "We can ask for another werewolf. I heard that Fire Fist is no less fierce than you. "

Ace can't do, Zoro thought. He's hunting down a vampire named Blackbeard so he doesn't want anyone to interfere.

"So, what's your answer?" Rob Lucci said again. "You two cannot refuse, can you?"

"I take it!"

"Zoro!" Robin yelled.

"OK. Well then, seven months from now we are waiting for you to return to MarieJois with that demon. Otherwise, we assume that you run away again so that the death penalty is still valid and I can't wait to taste how fierce you are, Roronoa," said Rob Lucci in a sadist stare.

Soon, the three vampires disappeared as quickly as the wind. Zoro and Robin still stared at the wide-open door left in the void. Then he talked to her without turning around.

"A few years ago, a leech named Aokiji once intercepted me on the street," he said quietly. "He said I'd regret to give you a place. He said you're just taking advantage of me. So this is what he meant? That you're looking for a werewolf like me for you to make a shield when they come in? I've wrongly trusted you, woman."

'Woman.' Robin frowned. It's been a long time that Zoro never called her that way anymore as they become closer.

"From the beginning, I should've kept firm that you, the leeches, are our eternal enemies." He was now looking at Robin closely to his eyes directly, like asking for an answer and looking for any gap from her eyes whether she time would lie to him or not this time.

Vain. Robin remained silent. It was a sign that she didn't deny it.

"Okay, let's leave that aside," Zoro went on, sighing. "What the hell is this Diable? And why a history from 900 years ago wants to be removed from your race?"

"Diable is the ancient form of vampires before they're evolved to normal vampire you know now." Now she opened her mouth. "Diable is vampire before they have the mind, only carnality. And of course, their strength is far exceeded than normal vampire. The vampires have buried the form into deep until finally in the next generation, the form was completely extinct 900 years ago. They did it because it would make them wild animals out of control of their greatness. Though, in evolution period, vampire still enabled to return to Diable form. This manifestation arises from an excessive desire for strength when they are pressed, or when emotion is unstable which then bursts out of anger so that their common sense and cold head are defeated. The main requirement that must be met is the phenomenon of the Red Moon-you know it is vampire's peak period. They get the power but the consequences are paid handsomely. They will not remember anyone, friend or foe. Vampires believe they're the strongest and the greatest mortal creature that God ever created and they don't need that bad form anymore so it was forgotten. Only ancient literature record it and some Professors in Ohara Academy learn the language, including the Rector."

"And you are the last descendant? Those damn leeches call you the Demon's Child, aren't you?"

Robin shook his head. "The Coven thinks Ohara Academy going to awaken this demon race again with this forbidden knowledge. That's where the nickname of the Demon's child addressed to me since I take History of Diable as my dissertation topic. Rector Clover didn't worry because most vampires now aren't pureblood and we need more research to test if we congenitally still inherit Diable genes or not before deciding to publish it. If we positively didn't inherit it, then The Existence of Diable and Its Extinction was safe to be added in History subject at school-same as human schools educating their race about human evolution. But Mariejois already took action and I stole part of Diable literature before they burn them all."

Zoro listened to Robin carefully, "I see, so Diable really exist!"

"You ever heard about them?" she was a bit surprised.

"Yeah, the old man from our race keep reciting an ancient poet about this demon. And he said we have the power of 'Oni Giri', Demon Cutter. That we must be ready if they reappeared, only we could kill him. No one believed his story. But I always wonder whether it's true or not so I've prepared myself to kill them."

"So, you can do it? Killing Diable?"

Zoro grinned. As Rob Lucci said earlier, it is true that he really felt challenged. "There's no vampire I cannot beat. Diable is just another level of vampires," he said so confidently.

"What important is ..." Robin lowered his head to pick up the scrolls of sheets of paper thrown by Califa. She opened it and found pieces of news clippings from the human world about the demon's figure. She scanned it, saw pictures of a Catholic school, the record of the victims, and other info. Quickly, Robin was able to summarize it because she had been finessed. "The Diable is Sanji."

"ERO-LEECH?!"

Robin was slightly drooping because he felt guilty. "I've known Sanji since he was a little boy, his knowledge was vast, he was quite intelligent from most vampire standards, and he was interested in the books I collected in my library. He might ever read the graffiti of my translation when I left for a while. But I had not translated it yet to the part that being a Diable will lose the common sense in return for the great power he received. I never thought Sanji could be... Is this because he's a pureblood?"

Zoro took the paper from her hand and read it.

"The vampire exterminator has lost 20 members, he is not a vampire, he has wings and horns, he is a demon, he is too strong, any weapon cannot hurt him-holy water and silver which used to easily hurt a vampire. Fire can't burn him because he even produces fire from one of his legs," said Zoro reading the piece, don't like how the monster is described so invincible. "There were no clear eyewitnesses, but we received information that the demon first appeared at East Blue Academy where one of our former hunters was assigned to be transferred there as a schoolgirl and we found the remains of her in the woods near the school. The vampires never killed the victim to that stage like a monster! Thankfully the students were on summer vacation, but some of the teachers and nuns who were picking up and guarding the school were also victims, the school is now sealed. "

Got there, Zoro realized. School ... Exterminator ... Student ...

"Wait... His letter?"

"Yes, that's the proof," Robin went on short.

"You gotta kidding me, woman! You said Ero-Leech is pureblood? The fuck is he doing all this time with that status instead of staying at his castle like common purebloods? Having fun with human school girls!"

"Sanji had abandoned his surname, Vinsmoke, since his mother died and he followed me because his family wanted him to marry another pureblood from Charlotte Family. We are now his family where he goes home on vacation," Robin replied, but suddenly realize something. "Wait... Vinsmoke Family are infamous because they discovered how to turn human into vampire slave. Right now, as their experiment continues, Mariejois pay them to produce slave soldiers who are still able to maintain their endurance under the sunlight as they used to when they were still human. We're facing Dragon's threat. I can hear war is coming. Now imagine if they knew their third son transformed into a kind of destructive monster. No wonder they want us to bring back Sanji ONLY ALIVE."

"Just tell me clearly what's gonna happen!" he started being fussed.

"Diable experiment. Diable production if the experiment was successful. Diable Era would come back if they couldn't control this monster. And whoever wins in this World War, we return to Dark Age. Your race can't escape from not being involved."

"Shit, you know what you had started, woman?" Zoro squeezed the paper. "Now I get why they're about to punish you."

"I just want to know the truth of history, I'm an archaeologist, nothing more!" Robin defended herself. "Who wants Sanji's incident happened?"

"What's done is done. Now, if I'm helping you to kill that monster, that's because I just don't want my race to be dragged into this war in the future."

Robin now stared at him deeply as she spoke softly. "Zoro…. Will you really kill Sanji?"

"Why not? Finally, I've gotten a chance to beat his shit out mercilessly."

"I won't ask to what you think of me now, but Sanji is…." Robin paused for a while. "He's been a part of your family, right?"

Zoro was silent. Yes, they always argue, fight, quarrel about unimportant things. But…

.

"Oi, Leech!" the green-haired called in full mouth. "This bear soup is delicious!"

The blond smiled. "I'm right, ain't I? Need me to cook again?"

"Yeah, I'll hunt for more bears because you couldn't," he chuckled.

"You shitty dog! I won't tell you if I pour poison in it."

.

"Tsk, that idiot is troublesome!" He slowed down the tone of his voice back.

"I guessed he ended up clashing with the vampire who was after his girlfriend, he was defeated and..."

"That's what I said he was stupid," he cut in. "And I am also an idiot myself who could accept vampire like you as my life partner."

"Did I ask you, will you kill him?" Robin asked repeating her question, avoiding Zoro's innuendo.

"You test me?" Zoro asked back, his tone rising again. "Listen, Curlybrow doesn't recognize anyone anymore, he does not remember us anymore. And according to this article, he EVEN killed his own girlfriend, the one he wanted to protect so hard. And you think I'll soften myself up against him? What do you want me to do? "

Hearing Zoro's last sentence, Robin became relieved. She knew the two people were always fighting and she wanted to make sure that the quarrel wouldn't actually spark of hatred. She hoped she didn't wrongly see the relationship between the two of them since the beginning, she never misjudged someone.

"I ask you to free him..." she replied.

"Tell me everything you know about this demon."
