The victor

As Mariamne charged towards Ami while continuing to spin like a top, Ami sheathed her wand and slipped out two black flintlocks from her mantle. 

"How exactly do you plan to impress with flintlocks?" Mariamne scoffed as she prepared to kick Ami in the head.

All Ami did was smile as she blocked with one of the  flintlocks.

BOOM!

Mariamne grimaced in pain as she was sent tumbling back.

"Ah, looks like your leg is still attached. I was worried I didn't lower the power on these things enough," Ami snickered.

"Your eyes deceive you, Ami. I shielded my leg from your attack. It was just the impact sent a shock wave through my body," Mariamne scowled as she slammed her feet down.

Her skin then began to turn silver before she cracked her shoulders and charged in.

"Going all-in on defense, huh? Well that metal skin's gonna weigh you down," Ami smirked as she dodged a kick.

"You bragged about those things having enough firepower to blast off a leg, so I naturally must take precautions," Mariamne scoffed as she unleashed a wind blast from her palm.

"Thanks for the wind, dumbass," Ami grinned as she sliced the oncoming blast with her flintlock and leapt over it towards Mariamne.

"How did you- Ngh!" Mariamne scowled as she found herself crossing her arms above her head as Ami brought her flintlock down on her. "Wh- What are those things!?"

"I told you, my latest weapons," Ami huffed as she swung her other flintlock around towards Mariamne's neck, landing a direct hit and sending her skidding away.

She then landed gracefully, allowing me to see her flintlocks appeared to have green blades on them, but what exactly those blades were made of was a complete mystery.

Mariamne, meanwhile, scowled as she touched the laceration on her neck. "You really made something nasty, you little shit. If I didn't coat my skin with metal, my head would be rolling around somewhere," she glared.

"So does that mean I win given the rules?" Ami smirked.

"No, her skin was coated in metal and she's still standing. The fight continues," Slavena proclaimed.

"Figures," Ami shrugged as she blasted off a shot at Mariamne.

Mariamne leapt into the air to dodge, causing the blast to smash into the barrier, and dissipate into staticky green energy. "Oho? Condensed plasma magic? Ami, you little sneak. If I'd known you'd created such a thing, I'd spare your hair in exchange for getting my hands on those to study!" she laughed as she summoned a long wooden pole and coated it in metal.

"You sure it's a good idea to be coating yourself in all that metal?" Ami smirked.

Mariamne let out a laugh as she summoned a waterball and splashed herself with it. "Go on, then. The only lightning that can hurt me is my own."

Ami sheathed one of her flintlocks and began charging her hand with lightning magic as Mariamne began running towards her. She then unleashed a lightning blast, which Mariamne seemed to dodge, however, a second later, Mariamne's whole body was engulfed in lightning.

"Ahhhhhhh... Told ya," Mariamne grinned as she suddenly burst forth from the lightning, now no longer sporting the metal coating on her skin or the pole she was wielding.

She quickly thrusted the pole at Ami, landing a direct hit on her stomach, causing her to hack up saliva as she staggered back. Mariamne then began thrusting rapidly, causing Ami to pull out her other flintlock again and use the blade on it and the other one to slice up the pole as she closed the distance to Mariamne.

"I'm impressed with the way you wield those, but sadly, I've seen through them," Mariamne smirked as she ducked and struck Ami's right arm, causing her flintlock to hurdle out of her hand.

However, Ami gritted her teeth and thrust her hand forward, grabbing hold of Mariamne's ponytail. "GOT YOU!" she shouted as she pulled with all her might.

Slowly, a malicious grin spread on Mariamne's face as her ponytail detached itself from her head.

"Wha- AH!" Ami cried as the ponytail suddenly morphed into slime and pinned her down to the arena.

"I was waiting for you to try and grab my "hair"," Mariamne laughed as she gave her now shoulder-length hair a haughty flick.

"H- How? I thought you cared about your hair," Ami trembled as Mariamne thrust her hand towards her neck, stopping it just before touching it.

"Oh, I do care about my hair very much. It's just... I don't like it growing past my shoulders, but to keep up appearances, I use slime to make it look long," Mariamne smirked as she retracted her hand.

"The match is over! The winner is Mariamne!" Slavena declared.

The barrier slowly vanished as Mariamne yanked the slime off Ami and refashioned it into a ponytail before attaching it back onto her head.

Ami slowly rose and picked up her second flintlock before putting it and the other one back in her mantle.

"Now, punishment time," Mariamne smirked as she snapped her fingers, causing a wooden stool to materialize in the middle of the arena.

Ami visibly began shaking as she trudged over to the stool and sat down on it.

"Don't worry," I'll make this quick," Mariamne grinned as she grabbed Ami's hat and tossed it aside.

She then summoned a ball of wind around Ami's head, causing her hair to begin flapping around madly. When it dissipated, all of Ami's long white hair was gone.

"Now for the finishing touch," Mariamne snickered as soap began to form in her hands.

"What are you- Mmph!?" Ami cried as Mariamne mercilessly encased her head and face in the suds.

"Oh, just giving you a smooth finish," Mariamne smirked as she snapped her fingers, causing another wind ball to form around Ami's head.

When it dissipated, all the cream was gone, leaving Ami's head smooth and shiny. However, as I squinted for a better view, I noticed Mariamne had done something nasty.

"MY EYEBROWS!" Ami cried as Mariamne flashed a mirror before her.

"Oops, guess they got shaved off with all the cream. That means it's no hair AND eyebrows for a year!" Mariamne laughed as she clamped her hand down on Ami's head and began chanting an incantation.

Once she was done, she released Ami and began walking off the stage in triumph.

"Looks like leader wins this one," Perl grinned as she and Penina rose from their seats.

"Yes, but had she known about our slime hair, perhaps things would have lasted longer," Penina chuckled.

"Is your hair also-"

"Oh, yes. The shorter the hair, the better in our line of work since long hair makes for a nice thing to grab hold of. Now, don't keep Ami waiting, I'm sure she'll need comforting."

I nodded before dashing down to the arena where Ami remained seated in the stool, tears oozing down her shocked face.

"Ami-"

"IT'S ALL YOUR FAULT! YOU GOT LOST, SO I HAD TO FIGHT HER, AND NOW I'M BALD! I LOOK LIKE A FREAK AND I'M STUCK LIKE THIS FOR A YEAR! I HATE YOU!" Ami cried as she ran away in tears.

My head slowly tilted down towards the ground.

"Don't be too hard on yourself. This fight was bound to happen sooner or later," Slavena sighed as she put her hand on my shoulder.

"But I'm the reason it happened. Ami did this to protect me, and got humiliated. I made her cry... How could I feel good about this!?"

Slavena let out a sigh. "There is a way to reverse the curse so Ami can regrow her hair. However, I doubt you'll be able to pull it off."

"What is it!?"

"Convince Mariamne to fight you, and beat her."
