As more and more people were killed the police became more and more suspicious about them. Yet despite their best investigation they just couldn't find any suspects to connect to the murders. Some of them suspected vigilantism due to the fact that the murderer went after criminals, abusers, and other people who were basically no good. Others suspected someone who was obsessed with pyrotechnics due to the fact that the murderer burned the bodies of their victims. But nothing added up. Then one day while looking into another murder they found something very interesting at the crime scene.

Unlike the others the body and the decapitated head had not been burned. Normally the murderer burned both the body and the head but this time he or she forgot which might have given them a lead. Both the head and the body were examined thoroughly and they discovered that the victim had not died from decapitation but instead of extreme blood loss. They also found unusual bite marks on the neck and that both the head and the body had no blood in it's system. It had all been completely drained. Still even with this newfound evidence the police couldn't make a connection. Well...One officer who was very superstitious suspected something supernatural was at work so he made an anonymous call to Professor Jellal Fernandes.

A man who specialized in matters concerning the occult and had knowledge pertaining to ghosts, exorcism, séances and of course vampires. After hearing the details regarding the body and the head he suspected vampirism was at work so he decided to pay Magnolia a visit. Cana had previously been a colleague of his and he figured that her knowledge on hematology would prove useful in his investigation. 

Knock-knock!

"Coming."

 The door was answered by Natsu. Standing at the door way was a very intelligent looking yet rather dashing young man with distinguished features. 

"Can I help you?" Natsu asked.

"Sorry if I'm intruding but I'm looking for Dr. Alberona, I was told she lived here."

"She does."

"Is she here at the moment?"

"No. Right now she's at the tavern. What do you want her for?"

"My name is Professor Jellal Fernandes, I'm an old colleague of hers and I need her help with something. When she returns would you mind informing her that I'm here and that I'd like to speak with her?"

"She'll be back any minute. You can wait here if Miss Scarlet says it's alright."

"Is she the lady of the house?"

"Yes. I'll tell her you're here."

He went upstairs to tell Erza that they had a guest wanting to see Cana. She told Natsu to let him in and later she came downstairs to greet the guest. 

"Professor Fernandes it's a pleasure to meet you." She said approaching him.

"Well...Hello." He said not expecting the matriarch of the house hold to be so lovely. "I apologize for arriving without calling first but I...I...I...I-"

"Are you alright?"

"Yes! Sorry I'm a little jet lagged from the trip. Again I apologize but it's very urgent that I speak with Dr. Alberona as soon as possible."

"Natsu has just left to bring her back here. He's pretty much her sober driver when she goes out for a drink."

"So she's still a booze hound? Some things never change." He chuckled.

While Natsu had gone out to retrieve Cana, Erza invited Jellal into the living room where they talked for awhile. 

"Can I get you anything while you wait? Coffee? Tea?"

"No thank you ma'am."

"If I may ask what is it you wish to discuss with Dr. Alberona?"

"With all due respect ma'am if I told you I'm sure you'd think that I've gone mad."

"Forgive me. I didn't mean to pry into your business."

"That's quite alright but I will tell you this. It does involve the murders that have been taking place in this town."

Erza suddenly became very stiff with worry. 

"Oh? Do you work with the police?" She asked.

"Not exactly but I hope that whatever I find will prove useful to them."

Erza started to feel very nervous. If this man knew something or found something that could lead the police to Gray heaven only knows what would happen. 

"Something wrong ma'am?" He asked after seeing how stiff she was.

"No Professor. It's just that I don't like to think about those murders. They...They frighten me." She told him. "They make it less easy for me to let my nephew and my stepsister leave the house."

"I can understand that. I don't mean to frighten you but I do believe that you should be on your guard and don't leave your home after dark."

"Thank you for your advice Professor Fernandes."

"Miss Scarlet we're back!" Natsu called when he returned with Cana.

"Ah Cana so good to see you again." Jellal said. "You're not drunk I hope."

"I was close to it." Cana said. "Before you had Natsu drag me back here."

"Forgive me Cana but it was circumstantial."

"Well in any case, it's very good to see you again Jellal. How are you?"

"I've been better. Cana if you don't mind I'd like to talk to you in private."

"We can speak in my office."

Once they were alone in Cana's office Jellal handed her some blood samples he had brought with him.

"What are these?" She asked.

"Blood samples from the recent body that the police found. It was given to me anonymously and I want you to examine it. See if you can find anything unusual about it."

"Like what? Aids?"

"No. Like a change in the D.N.A of it."

"I don't understand."

Jellal looked around to make sure that no one was listening before he spoke again.

"Cana do you believe in the existence of vampires?" He asked.

"You're not really serious?"

"I am. You know there are many well documented cases."

"Well I know about the legends. That they exist only at night and that they have no reflections in a mirror."

"This is no legend Cana. The body that they recently found was entirely drained of blood. Something had torn out it's throat and sucked all the blood which led to the victim dying."

"I thought they were killed by decapitation?"

"That's another thing. Once victims are dead their bodies are decapitated and burned. According to studies that's one of the best ways to kill a vampire or prevent a victim of a vampire from becoming one them self."

"What do the police think about this theory of yours?"

"If I told the police that the person they're looking for lived by night and slept in a coffin by day they would question my sanity. I need more evidence."

"Assuming you're right, how in the world are you going to prove it?"

"That's where you come in. I believe all the evidence we need is in those blood samples. That should at least be enough to convince the police that there is a vampire at large."

"Alright I'll look into this but I really don't think it's a vampire killing these people. I think it's just some crazy vigilante."

"Lets hope so. Because if the killer is human all you have to do is sentence him to jail or give him the chair then it's done but if it is indeed a vampire then God help us all."

"What do you mean can't you just kill a vampire?"

"Oh Cana if only you knew how hard it is to kill something that's already dead." He told her. "While you're working on the sample I want you to keep an eye out for anything suspicious. Like someone who's only seen at night or someone who has no reflection."

"I'll keep my eyes peeled." She said taking a sip of her flask.

"Get serious Cana." He said taking the flask from her. "This is a matter of life and death."

"Is it really? Or have you finally lost it?"

"I'm not crazy!"

"I never said you were."

"You just implied it."

"Well excuse me if this all seems a little insane to me. Last I checked vampires aren't real."

"They're real and dangerous. So be careful. Please."

"Alright. I still think this is nuts but for your sake I'll  watch for anything weird."

"Thank you."
