Slayer

Magic

Arvis smirked readying to scare the pants off the Wizards.
The lights snapped off, startling a few people.
"Arvis!" Makarov yelled. "Don't you dare do that again! Turn the lights back on!"
Arvis chuckled turning the lights back on.
"You got lucky this time" she smirked at the fire dragon.

2 Days Later
Laxus was drinking by the bar half listening to Freed talking, half listening to Mira singing. Things had been calm between him and Arvis. A good sign for the dragon slayer.
Out of nowhere there was a loud boom and a growl.
"What was that?" Lucy asked.
The guild had gone quiet, everyone wondering what had made the noise.
Then coming through the wall was Arvis. She hit the wall, breaking a table.
She got up from the rubble looking pissed. She growled storming back out to the backyard.
Laxus got up and followed her out.
Standing in the back was a woman smirking at Arvis.
"Who's that?" Natsu asked.
Laxus then realized that most of the guild was also outside curious of what was going on.
"Arvis!" Makarov called. Laxus looked down at his grandfather who stood next to him. "What's going on?"
Arvis looked back. "This is Agora" she said.
The woman across the yard chuckled. "Arvis and I go way back. We've been rivals ever since she humiliated me!"

Arvis smirked, chuckling. "Just because I beat her in front of everyone she keeps challenging me." Arvis cracked her knuckles. "Give it up Agora. You haven't beaten me yet."
Agora smirked taking a fighting stance. "It's been a long time since we've fought. I've gotten a lot stronger. Fight me Arvis and lose in front of your guild."

Arvis sighed. "Fine. If we must." Arvis took a firm stance.
Laxus was curious to see how strong she'd become. Even he wasn't very sure of what her magic was.
"Earth Make!" Agora yelled. A large square of earth erupted from the ground and went barreling at Arvis.
Arvis merely raised a brow. She held her hand out. "Spear!"
A spear with a deadly sharp tip appeared in her hand. There were a couple gasps.
Her outfit changed as well. It went from plain black shorts and a red shirt to very tempting flare bottom black pants and a cream colored crop top with a high collar. Her pale green hair was put into pigtails and ram horns were on her head.
Laxus put a hand to his nose to try and stop the nose bleed he was getting. She looked very sexy to the Dragon Slayer.

Arvis easily cut the chunk of earth sending it flying away.

"Ah, still fond of your demon requip" Agora said.
"Makes me happy" she shrugged.
Arvis slammed the end of her spear on the ground. A crack in the ground started running towards Agora.
Agora laughed. "Earth make landslide!"
The crack Arvis had made filled with muddy water and rushed toward her.

Arvis stuck the end of her spear in the crack. "Harden." The mud turned back to solid ground."

"Hmmm" Makarov said observing Arvis.
"What is her Magic?" Lucy wondered to herself.
Agora threw another chunk of earth and having enough of playing around she lunged forward swinging her spear. Agora dodged and jumped back.

They fought for a while Agora throwing any attack she could to push back Arvis but she was persistent swinging her spear not really in the mood to fight with Agora.
After a while she landed looking mostly bored and a little pissed. "This is annoying" Arvis said. "Your attacks seem weaker than ever. Give me a real fight."

Agora smirked. "If that's how you want it Arvis. I've been working on a new attack for the last three years and it's finally ready for you."
She put a foot back, digging it into the ground.
She began casting a spell and black magic began rising around her.
Arvis knew exactly what she was doing and she couldn't believe Agora had learned that spell.
The wind picked up and dirt flew through the air.
Arvis put a hand up to protect her eyes. "Agora!!" Arvis yelled.
She ignored her rivals call and built up more power to cast the spell.
"AGORA STOP!" Arvis tried to reason with her. "You don't know what you're doing! That spell is more dangerous than you think!"
