It was a dark night in this town. A man is running for his life through an ally way, something chasing him. The man was soon cornered in a dead end, he turned around and saw the thing chasing him, a purple lizard-like demon, its mouth was drooling for it was hungry.

Man: (terrified) Someone, help me!  Please! HELP ME!

The demon pounced toward him and the man closed his eyes. However, the sound he heard was that of metal slicing through flesh. He opened his eyes and was surprised to see the demon completely headless, it fell over and behind it, standing in the moonlight was none other than Erza Scarlet with a sword seeping with the demon's blood.

Erza: Leave now.

Man: Oh god, what was that?

Erza: I said, leave now. If you value your life.

She only said that as three more demons identical to the last one appeared out of the shadows of the alleyway.

Erza sliced a locked door near the wall, and the man ran inside.

Erza: Now then.

 She requipped two swords, one in each hand.

Erza: (sly grin) Shall we begin?

The three demons snarled at her as they jumped toward the Fairy Queen, only for them to get struck with multiple bolts of blue lightning, completely surprising Erza. Erza looked at the scorched demons and looked up to a rooftop. She was not alone, standing in front of the moon, shined by the moonlight was a woman. 

A young woman around Erza's age with blonde hair and blue eyes; she wore black leather pants, boots, with a black leather shirt and jacket, her shirt appeared to have a lightning bolt-shaped cut down the middle between her breasts. 

The blonde hair flowing in the light breeze, the woman chuckled a bit and gave a light grin. When Erza looked up toward the woman with swords at the ready, the woman had a blue electric aura surround her.

Erza: Lightning?

Flashback

Two days ago, Erza had taken an S-class quest issued by a church in a local town near Magnolia, more specifically the priest. 

He was an elderly man with gray hair, mustache and beard. Have eyes of black color and complexion of white color. He spots an open black daisy with red embroidery and a pair of red lines on both shoulders, in addition to having a red cross in the chest area. He wears a formal white undershirt with a dark gray tie.

The middle-aged priest described to Erza as the two were inside the church. Erza she sat on one of the benches.

Priest: It was terrible.

Erza: A demon disguised as a woman? Are you certain it's not a lightning wizard?

Priest: Absolutely. The town fell into ruins as soon as that so-called woman arrived, witnesses saw her commanding demons.

Erza: Go on.

Priest: And I saw it too, my dear. (Scared) That woman commanded lightning, and she used it to burn many of our people of our town to death.

He put his hands to his face, looking quite terrified, while Erza had a serious look on her face.

Back to reality.

Erza: So you're the Lightning demon that has been plaguing this town?

The she-demon merely grinned.

Erza: Have you nothing to say? I was told that you have used your power to slay innocent people, as a proud member of the Fairy Tail guild I will not allow this.

The blonde woman than casted lightning from her hands down to the alleyway for Erza. 

Erza blocked the attack by crossing her blades and broke it off. She then jumped from one wall to another, ascending for the rooftop as the woman continued to shoot lightning toward her. 

Erza was able to block and avoid all the attacks, she made it to the top of the roof and leaped up and fell to the roof and slammed the swords into the ground.

The woman jumped up and pulled out a weapon that had a menacing look to it. It was a large, single-edged blade with a red gem in the middle of it.

The woman fell and brought the blade down on Erza, who blocked it with her sword in her right hand.  Erza tried to bring her left sword to the woman's side, only for the woman to kick the arm away. 

Erza backed close to the edge of the roof as the woman came close to her with the massive blade, charged with her own lightning.  Erza blocked the blade successfully and pushed herself away from the edge, pushing her opponent back.

Both women clashed their blades with each other. The electric blade of the she-demon was very strong, but Erza was strong with her own weapons as well. 

Both women clashed and struck with their swords, but neither could get a hit in. The woman jumped backwards and landed on a chimney, she kept smiling.

Erza: I see you're enjoying this. You won't be for long.

The blonde then put her blade away and pulled out two pistols in each hand. She charged the guns with her lightning and fired. 

The bullets hit the ground in front of Erza's boots and caused a small explosion, forcing her to shield her eyes. When the dust cleared, Erza looked to find the woman had vanished.

Erza: Who was that? (Thoughts) There was something odd about that one, the way she fought. With a sword and guns, almost like... Dante.

Fairy Tail Guild Hall, the next day.

Guild Members: Go! Go! Go! Go! Go! Go!

Many of the guild wizards were all cheering this as they surrounded a table, the only occupants at that table being Dante and Cana, both were chugging down large mugs of beer. When they finished, they both slammed the mugs on the table, resulting in even more cheering.

Dante: (rubbed some liquid from his face) That's twenty-six. You sure you wanna keep going?

Cana: (red face) Rock on bro! *hiccup* I can do this *hiccup* all day. *hiccup*

Dante: Okay, one more round!

More beer was poured into their mugs, and they chugged once again. When Dante finished he slammed it on the table again.

Dante: That's number twenty-seven.

Though he was surprised he didn't hear a reply. He turned to Cana and looked with wide eyes.

Cana's face was more red than it had ever been, she was wearing the mug on her head like a crown.

Cana: (drunkly) Hey! Where'd that red sword *hiccup* go? (Wiggling her seat) Love you guys! *hiccup* Grandma is that you?

Cana then fell to the ground with swirls in her eyes and a lazy smile.

Dante: Well she's gonna sleep well tonight.

Happy was in a referee out fit and blew a whistle.

Happy: Cana is down!

Macao: (held up Dante's arm like in a wrestling match) The winner is Dante!

The whole guild cheered.

Elfman: That was so freaking manly!

Dante: Please, please. Hold your applause.

Dante got up and struggled a bit, the beer was now taking it's toll on him.

Gray: Hold on, I gotcha.

Gray put himself on Dante's arm and helped him to the bar and Dante sat on a table.

Lucy: I've never seen anyone out-chug Cana before.

Dante: I guess I have a higher tolerance than her.

Happy: Well she's definitely not gonna let you live this down, that's for sure.

Cana, meanwhile, was now being escorted back to Fairy Hills by Levy and Juvia.

Dante: Hey, where's the flame-brain? Haven't seen him all-day?

Gray: Knowing him he's probably doing something stupid.

Dante: (sweat dropped) Yeah, probably.

Lucy laughing at his comment.

???: I see you're having fun.

Dante, Lucy, Gray, and Happy turned to the source of the voice. Erza had just walked in.

Lucy: Oh hey Erza. Back from your job?

Erza: Not really. I only came here to ask Dante some questions.

Gray: You're still on the job?

Erza nodded.

Dante: So what do you wanna ask?

Erza: The quest I took was to help a church exterminate a demon that has been plaguing this town for quite some time, however this demon managed to get away from me.

Dante: Poor bastard. Guess you're gonna be hunting him down till he's dead huh? Well he's got my sympathy.

Happy: I wouldn't want to be hunted down by Erza.

Gray and Lucy having comical looks of fear at that thought. Erza gave an amused smile before speaking.

Erza: Dante, you wouldn't happen to know of a she-demon who uses lightning would you?

Dante: Lightning?

Erza: Yes, she also wielded a rather large demonic sword, along with dual pistols in each hand.

Dante: Well, demons have fingers right? That's really all you need to hold a sword and a gun.

Erza: Yes but she wielded them with great skill, and charged her own lightning into them. Most impressive if I must admit.

Dante: Can't say that I can help you. Demons can come in all shapes and sizes, sorry Red.

Erza: No worries, thanks anyway. 

Erza then walked out to the exit.

Lucy: You're leaving already?

Erza: Yes, I am still on a job. 

But then she remembered something and turned her head toward Dante.

Erza: Oh I forgot to mention, this demon, she wielded her weapons almost like you do. She also had the appearance of a woman with blonde hair.

Dante had a serious look on his face.

Gray: A blonde demon woman?

Happy: You sure it's not you Lucy?

Lucy: When was the last time you saw me using a sword or guns? And I can't use lightning either!

Dante: This lady sound pretty interesting. Maybe you should introduce us sometime, and I can teach her how to use those guns.

Erza: That won't happen. (She left out the doors) The next time I see her, she's dead.

Happy, Lucy, and Gray had chills sent down their spine.

Dante: Damn, you're one scary lady.

Lucy: Lightning she-demon. Someone who can go on par with Erza. Sounds like she could be trouble.

Dante: Speaking of trouble...  (he raised three fingers) Three, two, one.

Natsu: DANTE!!! (crashed through the ceiling) I'm gonna beat you this time!

Natsu fell with a fist gunning straight for Dante. Dante merely caught him by the wrist, and used the momentum from Natsu falling to swing him around and send him flying through the wall on the other side of the guildhall.

Lucy: Oh, geez. Here he goes again.

Gray: And we're on the same team with him, it's almost embarrassing.

Gray and Lucy both sweat dropped.

Happy: At least he's determined. Right Dante?

The blue cat gained a curious look when he saw Dante deep in thought; Gray and Lucy noticed this as well.

Dante's mind: Lightning huh?

Dante got a amused smile having an idea who this she-demon was.

Mirajane: Hey Dante. 

Mirajane called from behind the bar with a phone in her hand.

Mirajane: We got a phone call for you.

Lucy: Wonder who it is.

 Mirajane handed Dante the phone.

Dante: Yo?

Dante spoke into the phone, when he heard the voice on the other end he sighed.

Dante: So it was you. I knew it.

It was in the afternoon, the sun was setting and the sky was a mix of red, orange, and yellow. Erza was back at the church owned by the priest who issued the quest to her.

Priest: You still have not slain that demon?!

Erza: Not yet. But rest assured I will.

Priest: This must be dealt with immediately! If this demon isn't stopped, the damage could spread to other towns! She's terrible!

Erza: I do not believe she's as evil as you make her out to be.

Priest: What are you talking about? She's a demon!

Erza: I am aware of that, yet she had an opportunity to end my life, but she didn't.

Erza remembered her fight with that demon. She could have shot Erza, but she shot the ground instead and left.

Priest: How can you understand the motives of this creature?! She is an unholy abomination!

Erza: Do not worry, I will deal with this Demon; but I suggest that you leave. She is here.

At that moment, there was an electric current that zapped all the chandelier lights above and they all shorted out. Once that was done, the blonde she-demon crashed through the ceiling and landed in front of the priest.

Erza: So you decided to reveal yourself. (got up)

The woman looked to Erza than back to the priest, who was looking much nervous. Erza stood in front of the priest.

Erza: Let us finish our battle.

She then requipped into her Black Wing armor.

Erza: Go, now!

The blonde woman eyed the priest who was leaving, only for Erza to stand in front of her.

Erza: Did you not hear? I am your opponent.

 Erza than swung her sword only for the woman to backflip and avoid it, Erza flew forward and slashed again, but the woman jumped high to one of the chandeliers and pulled out a pistol and begun to fire electric bullets to Erza, who was able to block and slash them all away with her sword.

Erza flew upwards and slashed at the chandelier, only for the woman to fall back, she fired both her pistols towards Erza who flew down and slammed her elbow into the woman and they both impacted the ground, leaving a bit of a crater.

The woman was able to deliver a kick to Erza's right temple, forcing her off of her, she then grabbed Erza by the shoulders and used her enhance strength to throw her into one of the pillars.

The woman breathed a few breaths, before a bolt of lightning shot out from the pillar, forcing her to stand back. She had a surprised look on her face as she turned to see the dust clear and Erza now in her Lightning Empress Armor.

Erza: You seem surprised. This armor not only gives me the ability to use lightning, but also grants me resistance to most electric-based attacks; your own element won't be as effective as before.

The woman gave an amused smile and drew her massive blade once more. Both woman charged and clashed sword with spear. They blocked and parried each attack that was dealt. They stood on the benches of the church as they continued to clash. Sparks flew, both of friction and of lightning as their own electric weapons struck.

They both leapt back to opposite ends of the church. The woman charged her sword of her demon lightning to a large amount, almost till the entire weapon was covered. Erza mirrored the action with her spear. 

The blue glow from the large amounts of lightning illuminated the entire church. After staring down, quite a while they charged. Both weapons clashed. The resulting clash sent a massive stream of blue lightning straight up, breaking through the roof and leading directly into the sky. 

This caught the attention of a certain red-coated individual outside the church. The dust settled and both women were panting, both quite exhausted

Erza: You are indeed... quite skilled. But I will not... loose to you.

A certain, large sword was sent flying like a spear and impacted one of the benches in between them. Both looked to the entrance to the one who threw it.

Dante: If you're gonna continue like that, maybe you should go find some underground club or something. Your little show could probably bring in some money.

The blonde merely sighed as she walked closer to the entrance. To say Erza was surprised would be an understatement.

Erza: Dante! That's the dem-

???: You're late.

Dante: Am I? What time is it? (looked around) Too bad, doesn't look like there's a clock around here.

???: I told you not to be late, you never did listen.

Dante: I'm here, aren't I?

Erza: (to herself) Hold on a minute.

???: I mean, sure, everything's okay since neither of us are hurt. But, what would you have done if one of us was killed, what about then?

Dante: Relax, neither of you are gonna die that easily.

Erza: Excuse me! 

Dante and the blonde woman looked at Erza.

Erza: What is going on here?

Dante: What do you mean 'what is going on here'?

Erza: Is this some kind of joke? You two know each other?

Erza then pointed her spear to the woman.

Erza: Who are you? It's now evident that you can speak.

???: (looks at Dante) Don't just stand there, say something will you.

Dante: Hey don't look at me, you're the one who opened your big mouth. And it looked like you were having fun with that little misunderstanding.

???: Yeah maybe but...

Erza: 'Misunderstanding'? Perhaps you should explain this from the beginning so that I understand it.

Trish: Yeah, I'm sorry I had to put you on. You can call me Trish, and I'm Dante's partner.

Dante: (corrected) Ex-partner. Now these days we work independently. 

Trish: That's not a very nice way to put it.

Dante: It was your idea wasn't it? (walked inside with his arms crossed) And we probably work more efficiently apart.

Trish: (flirtatious tone) Are you pouting? Maybe you're lonely being all on your own.

Dante: Don't talk down to me like I'm a kid, and I'm not alone alright? Kat and I joined a guild. I totally dig it, and I can eat all the pizza I want.

Trish: Didn't I tell you for years to go easy on the pizza? And don't tell me that's all your eating everyday, god you're pathetic you know that.

Dante: Please don't talk to me like you're my mom, you're not the maternal type.

Erza slammed her spear into the ground getting both their attention. 

Erza: That's enough! I didn't ask about your personal lives, I want answers now.

Trish: Aw, if you're feeling a bit jealous honey. You should let yourself express that.

Erza: (anime angry mark on her head) Say what?! I am not jealous! (whispered to herself) Even though he does look handsome.

Trish: What was that?

Erza: Nothing! (turns to Dante) Now as for you...

Dante: Like I said, don't look me.

Trish then gave a light laugh, the situation itself was indeed very funny. Erza lowered her spear and gave a light smile, letting the situation soak in. Though there was something that she needed to know.

Erza: You knew it was her, didn't you? 

Dante: (nodded)

Erza: Why didn't you explain it before?

Dante: Well, I think you can understand, that in this business, people will want to test themselves against a powerful enemy. Can't say that I blame her, since neither of us have gotten much of a work out from our opponents.

Trish: And when I saw you, I thought the mighty Titania would give me more fun than my quarry.

Erza: Your quarry?

Trish then got a serious look of her own.

Trish: Why don't you come on out? You've been watching us all alone haven't you?

From behind the massive organ pipes at the back of the church, was none other than the priest of the church, with glowing eyes.

Erza: I see.

Trish: I'm here at the request of another person. Since this strange priest showed up, this town has become a den for demons.

Erza: And he felt that he was in danger so he hired me. Clever, I admit.

Demon-Priest: Don't misunderstand me. Putting an end to you three do-gooders will be easy, just thought I might avoid the hassle of doing so. 

The priest then began to step up.

Erza: A demon disguised as a priest, how ironic.

Demon-Priest: Now that you know what I am I have no choice. It's a hassle, but your all going to have to die here!

He then glowed white and tore out of his human disguise to reveal his true self. A giant white ape-like being with white wings, a large beard, horns, and red eyes.

None of the three heroes was even slightly intimidated.

Trish: (amused smile) Heh, tell me Dante, what do you think?

Dante: Unfortunately for him, since this horny little devil is new to town, he probably doesn't know what people like us do for a living.

Erza: To think I was fooled by such a weakling, I can almost cry.

Demon: ENOUGH OF YOUR JOKES!!! (charged)

Trish charged her sword with lighting, Erza readied her spear and Lightning Empress Armor, and Dante pulled out Nevan to add to the mix.

Dante/Trish/Erza: Joke's on you pal!

They blasted lightning; which exploded the entire back of the church.

Five minutes later

Trish: Fairy Tail huh?

She, Erza, and Dante walked away from the town.

Dante: Yep, Kat and I only joined just over a week ago. Best choice I ever made. I'm now actually starting to earn a profit.

Trish: That's a first.

Dante sweat dropped.

Erza: So tell me Trish, what do you plan to do now?

Trish: Not sure, the whole Devil Hunting business is starting to run a bit dry, this is the first job I've done in a couple weeks.

Dante: Maybe you could consider joining a guild yourself. There's a lot more fun than you think.

Trish: Maybe, that sounds like a good idea.

Erza: You know, I have been thinking. Seeing as you are now considering joining a guild Trish, and you seem to know Dante, perhaps you could join Fairy Tail?

Trish stopped walking for just a moment, even Dante was slightly surprised. 

Trish: Really?

Erza: We're always looking to accept new members.

Dante: Just warning you. You're gonna get a lot of collateral damage if she joins.

Trish: You're one to talk.

Erza: You'd definitely fit right in.

Trish (put her finger to her chin to think) Hmm, you know what? Why not? Could be fun.

Erza: Glad to hear it.

Dante: (sighed) Oh boy.

Trish: At least this way I can keep an eye on Dante here; and maybe even a rematch from the mighty Erza.

Erza: (smiled) I'll be happy to take you up on that.

Dante was already walking back.

Dante's mind: Trish is in now, this could be either really good, or really bad; Natsu's gonna really enjoy this. What's next?

It was night once again, the moon was covered behind the clouds of another town. On top of the rooftops stood a man, who could not be made out in the darkness. The man looked down onto a destroyed building.

???: So you're no longer here.

The man looked to a broken sign that read 'Devil May Cry'.

???: This just means we will meet again somewhere else. And I hope you're ready, for your sake.

The moon began to emerge from the clouds and shed some faint white light onto the rooftop, it shined at the man. He carried a katana with him, wore a blue robe and had white hair, with blue eyes, eyes that were more cold and dark than the coldest night in winter.

???: I'll see you soon, brother.

Chapter 6 ended.
