~The Haunted Castle~
Arvalis, Natsu and Lucy ran to the haunted castle as a long the way, a series of electricity made arrows flew through the air. Natsu quickly turning with a flamed fist knocked them away.
"Natsu!" Lucy yelled
"Keep going, I can handle this." Natsu says as Happy stuck around for him as Arvalis ran with Lucy towards the castle that came into view.
But as soon as they made it out of the haunted forest came a rush of water from below. Arvalis placed his left hand on Lucy's back and thrust her forward as a geyser was shot upwards on Arvalis tossing him upwards.
Lucy landed on the ground in front sliding a bit as she turned and looked to find a water made hammer slam onto Arvalis's back as he fell to the ground hard.
"R-run a Lucy!!" Arvalis said as she didn't want to go on and could help out.
"No I'm helping!" Lucy yells
"Then drown with him! Water make Tidal wave!" Yelled Mizu as a tidal wave hurled at them.
"Lost Blade Requip!" Arvalis yelled as his Greatsword appeared in his hand as he darts and slices the tidal wave destroying it.
"Lucy go inside!" Arvalis says as she grits her teeth and runs to the castle.
Meanwhile over at the battle with Erza and Kaze...
Kaze leapt forward and backwards with a wind made swords, one in each hand going at Erza. She had a tempest armor and wind blade sword as she was battling Kaze.
"Wind make Sparrow." Kaze says as multiple wind sparrows shout oh of her hand going around as Erza either sliced or dodged the multiple wind sparrows.
"Damn, your good...." Erza smiles as she makes her armor and sword vanished then required her heaven armor.
"Heaven Armor, Circle sword" Erza had multiple blades spin around while staying straight and hurled at Kaze.
Kaze was caught off guard as she was flown backwards and swords hitting her clothes pinning her to a tree. She gritted her teeth.
Over at the battle with Natsu versus Arashi....
"Fire dragon wing attack!" Natsu swinging his arms as a trail of fire went around and whipped at Arashi.
"Thunder make wall!" A walk of thunder appeared only for the fire to clash and cause an explosion.
"Thunder make cheetah."
Cheetahs of electricity was made as it ran at Natsu hitting him as he was tossed backwards. Natsu planted his feet down sliding on the ground as he leaned forward emitting flames.
"Fire dragon sword horn!" The quick retaliation caught Arashi off guard as he was hit and thrown towards a tree and fell to his knees.
Now at the battle with Arvalis versus Mizu....
Mizu was sending multiple thin streams of water at Arvalis as he was defending himself.
"Water make Current"
A curved water current rushed around and collided into Arvalis on his left side making his right hit a tree. He groaned as a fist made of water hurled at him.
He sliced it destroying it as when he thought he was gonna requip into a chain, the blade turned into a chain itself. The chain went around Mizu as he made the chain blade up and around and bring it down to have Mizu slammed to the ground.
All three fairies thought they had their opponents down, but the Theya siblings had a trick up their sleeves. Black markings appeared on their right arms.
"No way...it's devil Slayer magic!" Natsu and Erza were saying as Arvalis had no idea what kind of magic this is as he readied himself.
Explosions were heard from the forest as Natsu and Erza flew out of the forest and collided right into Arvalis sliding a bit. Soon Arashi and Kaze joined up with their sister Mizu.
"Ah, so you two decided to use your devil Slayer magic as well." Mizu said
"Indeed we did." As the three stood in front staring at the three fairies.
Just a moment ago inside the castle, Lucy was looking around when the sound of a door opened and there were footsteps. Lucy then saw a female in a white cloak with a hood up and saw black braided hair in front of her chest.
"What is going on out there and who are you?" She asked
"Are you Belle Phantasia?" Lucy asked
"Why do you ask?" She asked next
"I'm Lucy Heartfilia from Fairy Tail on a quest to get a one of a kind gate key as a reward for raiding this castle.
"Oh? Well, I am indeed Belle." She said lowering her hood.
"I was the one that sent the job request for the Castle Raid here." Belle said
"Well as much as that interesting, my friends need help to thwart the enemy from a merchant guild named Phantom Skull." Lucy said as Belle nodded.
Belle walked down the grand staircase reaching the bottom and walking towards the door when it just blew off as Natsu, Happy, Erza and Arvalis skidded on the floor.
"D-Damn it...their unison raid magic is powerful." Erza said as the three were having trouble getting up as Erza's armor reverted back to her regular (final season) armor and her sword vanishing just Arvalis's sword as well.
"Stand aside Fairies..." Belle says walking past the four as they lean up to watch.
"Just one? Now that's pathetic. Together sisters." Arashi says
"Unison Devil raid: Devil Storm Make, Clashing Thunder Wave!" The three Theya siblings say together as they did their stance as they then let forth a black torrent of water with black electricity and fierce black wind went at Belle.
Belle stayed perfectly still as the attack drew near and once near, she starts to breath in and the devil storm maker magic goes inside her mouth as she eats it. Everyone was shocked to see this.
"Devil magic....a good source for me....yummy..." Belle says with a grin.
"You three should run now....before I make my roar." Belle says coldly
"We're not scared of you! Right sis?" Arashi claims as his sisters nodded
"Too bad....I warned you." Belle breathes in expanding her lungs.
"Ghost God...Spectral Roar!!"
A turbulent of spectral energy shot out her mouth as the three siblings were hit and were thrown far away carrying them real far and beyond the haunted forest and then landed in the prairie where they became knocked out.
"Phew...that was good and a bit nasty...always hated eating devil magic." Belle says as the three fairies on the ground got themselves up.
"Holy cow! What kind of magic was that?!" Natsu asked
"I've never seen it before." Erza says
"One of many lost magic....God slYer magic." Arvalis answers the two.
"Your correct umm...your names please?" Belle asked
"I'm Arvalis. That's Natsu, Happy, Erza and Lucy." Arvalis pointed to each one.
"Nice to meet you all. Also, I am a Fairy Tail Mage that have been around since it was first formed by Master Mavis." Belle says
"Seriously?" Natsu's jaw dropped
"I'm in fact over seven hundred years old. I was born in the year X-Fifty." Belle said
"That really is over seven hundred years ago." Erza says
"Yet you look so young ..how are you this old? Are you cursed like Zeref?" Lucy asked
"Oh no. I'm not cursed at all. In fact.... I'm a Demigod....the Demigod and princess of the underworld. Daughter of Hades, God of the Underworld." Belle says as everyone was so stunned and shocked.
"Holy fricking crap...." Natsu says
"I'm speechless." Erza says as Belle looks over at Arvalis who's keeping his cool.
"You....your father....it's Alubar Zendai isn't it?" Belle asked as he gasped as she knew his father.
"Y-Yeah.... that's my father's name....you met him?" Arvalis asked
"I have.... he's a good man and helped me in a lot of jobs when he first joined Fairy Tail." Belle said
"You have to tell me more about him later." Arvalis says
"I will...so now....the job about the Castle Raid quest...We have to go down below the castle.....into the dungeon." Belle says
"Into the dungeon?" Happy questioned
"Yes Happy....follow me." She says as she walks up to the grand stair case as she went off to the right and tipped over the statue of a lion and pressed a button. The middle section of the stairs then slid downwards as torches began to light up.
"Woah! Awesome!" Natsu seemingly excited
Belle went first while grabbing a torch off the wall. Arvalis did the same too as the group walked down into a wine cellar first where there was a bar caged. Belle passed the torch to Erza as she grabbed onto it.
The handle was a bit intricate as she then opened it and then the group went on. They must've walked really far down a long winding path until they came up to a big circular chamber were lflames erupted all around the room.
They all saw a door at the very end where Natsu instantly ran over.
"No! Natsu!" Belle tried to warn quick but the ground began to stir underneath him. From beneath the ground, a giant necro lizard emerged snarling with an orb at its center beneath it.
Natsu rolled backwards back towards everyone. The group now knowing why Belle didn't move on the first place.
"Now we battle." She says as the group then split off as Natsu would occasionally jump in and try to kick or punch with flames and feet raged with fire.
The Necro lizard swiping and using its tail to swing around towards the group with force roaring.
Belle was trying to focus on attacking the orb, but gets halted.
"Damn it." She muttered as she jumped away, Erza and Arvalis requipped their swords as they went in to slash at the Necro dragon to have it drop some pieces down, but it was healing itself.
"This thing can heal itself?!" Erza became frustrated as Arvalis just darts in relentlessly slashing as Lucy summons Leo and Capricorn both out as they went in and attacked.
The Necro lizard noticed the celestial spirits coming in to attacks it swept its tail at them, but Capricorn hurled a black sphere at it causing it to roar and then Leo going in for a Regular impact. Leo's hand glowing and emanating a yellow sphere on its hand slamming into its left slide.
"Fire Dragon Iron Fist!" Natsu yells with a flamed fist
The Necro lizard turning to swipe at Natsu when Erza and Arvalis swooping in with an upward slash at it. The Necro lizard was uplifted a bit revealing its orb underneath.
"Ghost God: Spectral Claw!" Belle swiped her right arm with curved fingers as three slash marks came about on the Necro dragon. The middle slash cracked most of the orb that it exploded and the life within the Necro dragon vanished and the corpse falling down.
It became motionless. Everyone walked in closer to get a better look as it wasn't moving and truly dead.
"Your an amazing mage Belle." Lucy says
"Your ghost God slaying magic is incredible." Erza said
"Thank you...and now...to the final room." Belle says as they move around the Necro lizard and open the door. Once open, they came to a room that looked like a studies room.
A desk, bookshelf and more. There was even a coffin in the middle of sorts.
"A...coffin?" Lucy questioned
