In the kingdom of vale Jaune Arc was sitting outside of one the buildings by himself. He told his team he wanted to be alone for a little while.
He sighed, "I can't believe how useless I am. How did I become the leader of Team JNPR? Some leader I am couldn't protect the two people I cared the most about. First I loss Pyrrha and now I've lost Ruby. Heh maybe my sisters were right I don't have what it takes to be a huntsman."
A mysterious young man appeared behind Jaune. "Now I wouldn't say that Jaune."
Jaune quickly turned around by instinct pulled out his sword. When he turned around he saw a young man probably around 23 years old. The man wore a black leather jacket with a red undershirt along with black fingerless gloves. The man was about a few inches taller than Jaune.
Jaune gripped his sword tight, "Who are you and what do you know about me?"
The figure said, "My name is of no importance. I know that you wish to redeem yourself. You feel weak and useless. You think of yourself as a failure of a leader. I am here to simply give you the power and chance to redeem yourself. What would you say if I told you there is a way to save the one you call Ruby?"
Jaune said shocked, "Wait are you saying she is still alive?"
The figure nodded, "Indeed after she disappeared from your world she was sent to another world. I can show you what has happened to her."
Jaune said, "Please do I need to know what happened to her." The figure smirked and waved his hand in the air. A small window like object appeared in front of Jaune.
The figure said, "This is a windows into another world. It will show you what has happened to Ruby." In the window it showed Ruby fighting off a large Grimm that looked similar to a Beowulf. Ruby was putting up a fight, but it showed that she was weakened. The Grimm seemed to turn into some sort ghostly figure. It entered Ruby's body causing her normally silver eyes to turn red and the image disappeared.
Jaune said, "What happened to her? What kind of Grimm was that?"
The figure said, "That Grimm is one unique to that world. It's darkness overpowered her and possessed her."
Jaune said shocked, "What!? How can I free her?"
The figure said, "You must defeat her and force the Grimm's spirit out of her. So will you help her?"
Jaune said without hesitation, "I will save her and force that Grimm's spirit out of her. Just tell me what I have to do to get to that world."
The figure said, "All you must do is shake my hand and I'll grant you the power to force the spirit out of her and I'll send you to that world."
Jaune said, "Alright I'm ready to go." Jaune did as he was told and shook the man's hand. He felt power flowing through from the man to him. Suddenly Jaune was teleported from vale to the other world.
Once Jaune had disappeared the man smirked as he contacted his master.
The man said, "I have completed my assignment Lady Salem. I have sent Jaune Arc to the other world and granted him the power of the darkness residing in his heart."
Salem said, "You have done well Yami. Return to base for now."
The man now known as Yami said, "As you wish my lady." Yami disappeared in a cloud of black smoke.
Jaune landed in the other worlds and took a look at his surroundings. Where he had landed seemed like a town square. There were stores that were selling products ranging from clothing to electronics. There were multiple people just going about daily business no Grimm, gangs, or thieves around. It was a very peaceful scene that Jaune wished is what Vale was like right now.
Jaune said, "Well things definitely seem more peaceful here than back home. Anyways I have locate Ruby and defeat her to free her from that monster's control. The only problem is that I have no idea where to start looking." Suddenly he heard cries of help from people and head towards the direction where the cries for help came from. Once he arrived he saw a group of civilians being attacked by Grimms and…..Ruby? That guy was right in Jaune's eyes it looked like Ruby was attacking the civilians.
He called out, "Ruby! You can't let that monster control you!"
In reality Ruby was fighting off some Grimm that were attacking the civilians until she got distracted by a familiar voice calling out her name. She looked at the source of the voice and she was shocked.
She said surprised, "Jaune?! What in the? What are you doing here?" This had to be impossible Jaune should be in the world of Remnant not here. An Ursa Grimm pounced onto Ruby while she was distracted.
Ruby said, "Get off of me!" She managed to fire a bullet from her scythe launching the ursa into the air crashing a few feet away, but the Grimm still seemed to be standing. Ruby once again looked back at where she had seen Jaune, but he was gone? Was she just imagining him? That was the thought that entered her mind until she felt something slash her back thankfully her aura protected her but it still knocked her back about a foot. When she looked at what had attacked her she saw Jaune with his sword out.
Ruby said, "Hey! Jaune what the hell was that for? Our enemy is the Grimm not each other!"
Jaune growled, "Shut up you monster! If the enemy are the Grimm why are you attacking innocent civilians!"
Ruby took a defensive stance, "What are you talking about Jaune I'm fighting the Grimm not the civilians?" Ruby didn't like how Jaune was looking he had a dark aura around him. His eyes had a blood thirsty look in them.
Jaune once again charged at Ruby with dark aura around him getting bigger. "Don't lie to me you servant of Grimm! I saw it with my own eyes you just sent a civilian flying into the air. Release Ruby from your control right now before I force you too!" Jaune rammed Ruby which sent her flying into a brick wall.
Ruby seemed to be losing her energy. Her aura wouldn't last much longer if Jaune kept up with powerful attacks like that. She knew something or someone had to be messing with Jaune's mind causing illusions. She had to snap Jaune out of it. She got up to her feet, "Listen to me Jaune someone is messing with your mind! You have to snap out of it before one of us gets killed!" He didn't seem to be listening to her as he continued his assault. He ran towards Ruby with speed almost rivaling her semblance. As soon as he got close he started slashing Ruby non-stop. She managed to block some of his attacks by spinning her scythe in circles, but she wouldn't last much longer. Ruby started to feel her aura dissipate this was bad news without her aura to protect her it was very possible for her to die. Jaune started focusing his attack on the hand Ruby held her scythe he managed knock her scythe out of her hand leaving her without any form of protection. Ruby finally felt her aura run out leaving her wide open for major injury and possibly death. Jaune put his sword just barely far enough away from her neck that it didn't slit her throat.
He said, "Give it up Grimm! Leave her body now you have no way of fighting back."
Ruby made one last attempt to talk some sense into Jaune, "J..Jaune please listen someone is messing with your mind. There is no Grimm controlling me. I was fighting Grimm not attacking the civilians."
Jaune growled, "Shut up!" He slashed Ruby's arm leaving a large cut on her arm. Ruby cried out in pain she could feel the blood flowing from the cut in her arm. She couldn't die here not now, but she was drained and had no energy left to fight. Her vision started getting blurry. Before her eyes closed she saw a blur of yellow knocking Jaune off her.
She heard a voice saying, "What the hell are you doing? You are not killing my sister!" After hearing that voice Ruby's vision went black. She could feel someone wrapping something around her cut, but not much else.
