The Mirror Dimension is a parallel dimension that mimics the world's plane of existence. It is complete with the same surroundings and inhabitants, but its visual appearance is distorted like a fractured mirror. Accessible only by users of magic, sorcerers use the Mirror Dimension as a reconnaissance platform and a teaching aid for magic practitioners since it can be reshaped and manipulated freely without fear of adversely affecting the natural order of the world.
However, Jaune could enter a Mirror Dimension without inhabitants, a desolate version of the original. Here, Jaune wasn't training to use his magic. No, at this moment in time, Jaune was facing off against Scáthach. It was a do or die moment.
RWBY, NPR, Arc Family and Rose/Xiao Long family were confused about where they were.
"Whoa! What is this place?" Yang asked. "It's kind of freaky. The fractured mirror effect is freaking me out".
"Don't be scared," Jaune said. "Nothing bad is happening. I brought you all here to act as a witness".
"Witness for what?" Weiss asked. "And where is this place?".
"This place is known as the Mirror Dimension," Jaune replied. "A parallel dimension that mimics our world's plane of existence".
"Okay! Enough of the mumbo jumbo," Yang said. "Why are we here? And how do we get back to the real world".
"I can bring you all to the real world now if you don't want to watch a fight of a lifetime," Jaune said. "However, if you wish to watch, just kick back and enjoy the show".
"So, we're acting as a witness to the fight happening here?" Ruby said. "Who's fighting?".
"You'll find out later when it starts," Jaune said. He then used telekinesis to bring everyone in the air. He then created a platform that is covered in powerful defensive magic. "This area will be the safest place for you during the fight. Do not go out of the barrier, or you might get hurt".
"You're doing it now, aren't you?" Haruhime asked. "You're challenging her".
"I am," Jaune said. "That's the reason why I had to make a powerful barrier around everyone. You know that we aren't the same as normal people".
"Don't die, Jaune," Haruhime said. This confused the Arc family. "Please, don't die".
"What the hell is going on?!" Joan asked. "Why are you saying those words to Jaune?".
"That's because what he is about to do could get him killed," Haruhime said. Joan was about to stop Jaune from leaving, but it was too late. "Jaune is challenging Scáthach to prove himself".
Jaune headed to the ground. Once there, Scáthach came out of his shadows.
"So, you're finally fighting me to prove yourself," Scáthach said. "Do you believe that you can defeat me? Know that I won't hold back".
"I know you won't hold back, and I know I can beat you," Jaune said. "And I will do so with your speciality of using a spear".
Jaune and Scáthach then took out their weapon. In an instant, they clashed. The wind pressure from each attack was so powerful that nearby brick walls were sent flying. The speed at which Jaune and Scáthach moves are near imperceptible by people who aren't used to watching high-speed fights.
Jaune stabbed Gáe Bolg through Scáthach, and he tossed her in the air. Using Kokū Shundō, Jaune got behind Scáthach and swings Gáe Bolg down on her, making her crash to the ground. However, this does nothing to her.
"Holy shit! What the hell are those two?!" Tai shouted. "Are they even human? With each blow of their weapon, they're destroying their surroundings".
"Oum! Damn! Now I understand why Scáthach said that we couldn't beat Jaune even if we all worked together," Yang said. RWB and NPR nodded at her and continued watching the deathmatch. "No wonder he was able to stop Nora's Magnhild with a single finger".
"I didn't think that people can get that strong," Weiss said. "I already saw veteran huntsman and huntresses as the peak of what Humans and Faunus are capable of. This…This is a whole new level".
No matter how hard Jaune hit Scáthach, she would always remain unscathed. Gáe Bolg's curse that makes wounds made by the spear hard to heal isn't working on Scáthach. Meanwhile, Jaune was bleeding from when Gáe Bolg Alternative hit him.
From within his Inventory, Jaune took out Gáe Buidhe. According to Alice, Gáe Buidhe doesn't have the power to kill Scáthach. However, it can stop her from healing. How this works is a bit complicated.
Jaune didn't hesitate to stab Scáthach in both her shoulders. As Alice advised, Scáthach is no longer healing, and the injury on her shoulder is impeding her ability to wield her spear.
Despite the injuries of Scáthach, she was still able to keep up with Jaune as she has more fighting experience than he does. Her ability to predict Jaune's movements were enough to counter Jaune.
When Scáthach saw an opening for her to strike, she hesitated for a moment since she was hoping for Jaune to win, but she took it in the end. She knew that if Jaune found out that she held back, he wouldn't accept the win if he won. So, Scáthach stabbed Jaune in the thigh.
Jaune anticipated Scáthach's attack, so he placed Gáe Bolg in the path of Gáe Bolg Alternative. He then used Gáe Buidhe to slice off Scáthach's hand. Unfortunately, it failed. Scáthach was able to take out another one of her Gáe Bolg Alternative to block Jaune's attack.
In the sky, the people watching the fight were horrified at the scene they were watching.
"A-Are they killing each other?" Ruby said. "This…I thought they were only going to have a spar".
"Same here, Ruby," Yang said. This is the first time they've seen someone fight to the death. "Is what they're doing even worth it?".
"To Jaune, it is," Haruhime said. "He told me that this was something that was going to happen no matter what".
"I'm going to kill him!" Joan said. "When this is over, whether he is alive or not, I'm going to kill him!".
Angry would be an understatement of what Joan was feeling. She couldn't believe that her son was doing something so stupid.
To Joan and the others, what Jaune and Scáthach are doing is stupid, but it's about more than just pride to the two.
Scáthach long ago challenged Jaune's desire to give her a better outlook in life. She and Jaune have been waiting for this day. The day Jaune was strong enough to stop Scáthach's desire to die. But there was something Jaune didn't know. His desire has won long ago.
Just as Jaune can see Scáthach's memory in his dream, Scáthach can see Jaune's life. When she saw Jaune with his family, she didn't think anything of it. However, a year after watching Jaune's life, she started to crave the love of a family, and this affection was concentrated on Jaune. That's why, when Jaune summoned her and told her that he was in love with her, she was overjoyed.
But Scáthach isn't just an average person, she was a one of noble birth. Scáthach had her own pride. She wouldn't accept anyone that could not stand by her side. Hence, she made a deal with Jaune. Beat her, and he gets all of her. Scáthach's heart, body and soul would belong to Jaune.
"Have you had enough, Jaune?" Scáthach said. "You can always challenge me another time".
"No! This will be our last fight!" Jaune shouted. "I've known for a long time that you've had feelings for me for a long time. I've made you wait long enough. No more, this will be our last fight! I either die today, and you get your wish of dying. Or I win, and we can be together as our hearts desire".
"Let's end this fight in one last hit!" Jaune said.
Scáthach can see that Jaune was up to something, but she could not figure out what it was. She then saw Jaune drop Gáe Bolg and retain Gáe Buidhe in his hand.
With Gáe Buidhe in hand, Jaune would use a move he's been modifying to be used with a spear. Two years have passed since Jaune tried to recreate this technique to be wielded with a spear. Yet, this is the first time he was using it on someone.
Jaune took a stance and waited for Scáthach to make her move. And when she did, Jaune initiated the technique.
"Tsubame Gaeshi!" Jaune shouted.
Scáthach had no room to retreat, no room to defend and no room to block even with two Gáe Bolg Alternative. It was too late to do anything, and Jaune was able to cut off both her arms and legs. With Gáe Buidhe, she wasn't able to heal. Scáthach may not be dead. However, she was now immobile and unable to do anything.
Jaune…won.
