Author: I don't have a very good understanding of Setsuna's attacks, so I gave her some original ones based on what I do know of her skills. (A lighting attack, a rock cutting attack, a cherry blossom attack, etc)

Chapter 2- Fire and Lightning

Setsuna and Red dash towards each other. Red draws his sword, Setsuna deflects it to the side and comes in close. Swinging her blade, the boy disappeared before connecting.

(Instant movement!) Setsuna sensed something behind her and quickly put her sword over her head. The downward attack forced her down, she spun around to the side to dodge and strike. Red jumped back to avoid the low slash. He stood sheathing his sword, entering his first pose again.

"I'm impressed, you're strong alright," he started. "But it'll take more then that to beat me."

Red charged first as Setsuna readied herself. Within striking distance he stops and pulls a quick draw attack, Set blocks it but several attacks followed. She was finally overpowered and taken down.

(Those attacks are fast.) Setsuna tries to get up and stare at her foe. (At least they're not the same speed as Takahata-sensei's. But they're still a problem, I need to make him keep his sword out.) She stands up straight, bringing her sword above her head.

"Rock Cutter!" Setsuna sliced the ground she was standing on, cutting up part of the stage and sending small debris and a bunch of smoke into the air. Red didn't flinch as the smoke rises, only tightening his grip on his sword. Setsuna dashes from the smoke at high speeds towards him, her sword seems to be surrounded by white sparks.

"Lightning Cross!" Setsuna swung from afar horizontally. A wave of electricity flies from her sword Red jumps back as it lands where he was standing, creating a line of lightning as tall as he his. Looking up he sees his opponent in the air, she swung her sword vertically at him and another wave of electricity shot out.

The red haired fighter jumped to the side as the young girl breaks through the wall of lightning, following him at a close range. Her sword was still covered in electricity as she attacks him. Forced to defend, Red takes out his sword and blocks a direct attack. As soon as they connect, Setsuna appears behind him, Red quickly turned to deflect a stab aimed for his heart.

(She's gotten faster, is it because of the lightning?) Red jumped back a little to create space, Set didn't give him time to recover as she went in quickly to attack while he was still in the air. Setsuna aimed up with her attacks while he tried to fight back from the air as they made it to the edge of the stage where Setsuna jumps up to meet him with her blade. They flew a little, deadlocked and face to face before Red holds his sword with both his hands and pushes Set down as he lands on the seats. The boy returns one hand to his sheath at his side.

They move instantly as soon as they landed, meeting each other with a slash. He gives off a happy smirk but Setsuna keeps her focus, then they pass each other landing where the other was standing before.

"Cutting Wind! 100 Cherry Blossoms!" Setsuna slashed at the air as pink petals flew around, the slice of her sword created a wind for the petals to follow as Red wonders what this attack could be. He jumps back up to the stage to avoid the attack just as the pink petals hit where he was standing before, leaving many small cut marks on the floor.

(The petals can cut? I need to be more care-) Red brought his guard up as Setsuna came in again. He had to deflect attacks from one side and block from another as Setsuna's blade seemed to increase in speed. Set faints an attack to his right side, taking the bait Red goes off to defend it as Setsuna quickly twirls around to attack his other side. There is no way he can move his sword fast enough to save himself.

CLANG!

(Impossible!) Setsuna is shocked to see her sword blocked mere inches away from her opponent's face. (He used his scabbard? But the sound I heard, it's made of metal!)

"Using your lightning attacks to increase your speed, and even your power. You're definitely not a regular swordsman." He told her. "However, while I can't tell you my real name just yet. Let me show you what it means."

He attacks with his sword, making the girl jump back to evade it. Bringing his sword to his side, he swings it, launching a wave of flames to his opponent. The young girl jumps into the air to dodge but she sees Red pointing his sheath towards her, it shoots out a stream of fire.

"Cutting Wind!" Set counters with her own attack, the pink petals and the fire collide in the air. They negate each other completely as Set lands back on the ground.

(Fire! It should've been obvious.) Setsuna readies for impact as her opponent instantly moves in front of her. She blocks and deflects both the sheath and the sword with great difficulty as she steps back after each second. Finding an opening, she swings her sword while it shoots out lighting, Red jumps high into the air and ignites both his weapons to stab the ground. The girl quickly retreats as the burning fire hits where she once stood, following the attack a huge geyser of fire sprouted from the ground. For the brief time it appeared, it was three time taller then Setsuna.

"Well?" the boy asked. "Is that really all you have?" He prepares himself once again, holding his sheath in front of him at face level horizontally and his sword behind him with its tip above the sheath and pointing at the girl.

Setsuna stands up and reaches in her pocket to take out a curious looking card. "Telepathia!"

Red seems to be quite intrigued by the action. (A Pactio card, so that kid I bumped into really is who I thought he was.)

Far away, Negi hears a voice. "Negi-sensei! Negi-sensei!"
"Dwah? Setsuna-san?" Negi looked around until Asuna bonked him.
"She probably using the pactio card aniki!" Chamo told him.
"Oh yeah!" Negi takes out her card and begins talking. "Setsuna-san, what's happening?"
(I need help Negi-sensei. This guy, he's strong.)
"What do you need Setsuna-san?"
(I'm going to use the artifact, can you send some magic my way as well? It looks like I'm going to need it.)
"You need some magic? I can do that." Negi confirmed. "For how long?"
(I don't know. Give me four, no five minutes for now.)
"Right," Negi take out his wand and lifts it high.
"What's going on Negi?" Asuna asked.
"Setsuna needs some help, so I'm giving it to her," Negi chants his spell to grant Sestuna additional power. An aura of magic quickly floats from where he's standing to the stadium.
Sestuna holds her card out to her side, "Adeat!"

The card glows and transforms into a smaller version of her sword. A magical aura appears from nowhere and immediately surrounds Setsuna. It glows around her as she takes in the power.

"That's more like it," Red ignites some fire from his feet and is now surrounded by small flames.
"I will get Knonka oujo-sama back," Setsuna keeps her pure focused look on her face. Both her blades covered in electricity.
"Then prove it to me."

"So, Negi gave her a magic boost eh?" Kotaro observed them powering up on the stage. "Now thing are going to heat up."
"Now we can really see how strong both of them are," Kaede added.

The flames and the magic disappear from view and are absorbed by the fighters. They dash towards each other with amazing speed, their collision creates a small dust cloud. Red deflects her sword from up above him and thrusts, the girl jumps back but fire followed her from the weapon. Twisting off to the side, Set manages to avoid the red stream and launch a lightning wave.

Her opponent ignites his sword and slashes down as the wave nears him, cutting it in half. Following up he instantly moves towards her, they exchange attacks furiously. Sword against sword, sheath against knife, lightning against fire. Their weapons made a lot of noise in this quiet stadium, their speed unbelievable, their power equal, their skills unimaginable. Several thrusts, pokes, evades, parries, counters and blocks were made as the two fighters kept exchanging attacks, exchanging skills, exchanging their respect.

Eventually, all four weapons crossed. Setsuna summons up more lighting to her swords and pushes hard on her weapons. The boy is sent flying as he guards from the lighting cross. Calling forth his fire he cuts up the cross with a single swing from both weapons. Red stabs the sheath through the stage floor, Setsuna jump off where she stood as a pillar of flame burst from the ground. The boy ran through the flames towards her.

"Cutting Wind!" Setsuna sent a gust of wind his way. Red stops and swings his sword, launching a wave of fire that crashes with the wind and petals.

Looking up, Setsuna sees her opponent slash downwards. The girl rolled and charged, they became deadlocked once more. Set had made it so she was holding back both his weapons with just her big sword, she brings the smaller sword back and attempts to slash him, only sending a wave of lighting to an empty stage as the boy flipped over her. Setsuna brought her swords behind her, the boy only held his weapons vertically on each side, blocking the attack.

Setsuna stood up quietly and the boy relaxed his arms. They stood in the middle of the stage, back to back, in utter silence. A small gust of wind blows through them, rustling their hair. The two combatants felt the wind blow with their eyes closed, almost enjoying it. The wind slowly dies down as the two fighters reveal their eyes.

Setsuna quickly turned around to stab the boy, he too turned and deflected the attack while sending his own. The girl used her other weapon to keep it away from her body. Using the second weapon, she aims for the head. Red goes low and attempts a sweep kick, having Setsuna back flip to avoid it. She flips some more to create some distance between them.

Red got up while Set lands, he was smiling at her, praising her skills. It may not look like it but Setsuna also respected her opponent, though the battle wouldn't have gone like this if he just challenged her outright. She keeps her determined look as they race towards each other once more.

Kotaro and Kaede sense something away from the stage, a green arrow hits the ground between Set and Red. Both stopped in their tracks, watching the green arrow disappear.

(That arrow, it's made of magic.) Set and Red look over to where the arrow came from.

There a girl as old as Red stood, she wore an archer's clothing, white at the top with green pants, and held a mysterious bow almost as tall as she is. She had short but bright green hair as well as green eyes, her bow seems to be just a bigger, more decorated version of a regular one. It too had gems, only they were green and the gems were placed at the two ends of the bow, shining through both sides. Not only that, the seemed to be a pair of blades on the weapon.

"So they sent her…" Red muttered. Setsuna questioned within herself who and for what?

Kotaro was about to move when Kaede held him back. "Let's see where this goes first."

The girl pointed her bow and pulled a magic arrow from it, aiming for the two of them.
