I don't own RWBY just my oc.

Glynda Goodwitch stood in front of her class, she was thinking which students should start off first and she was interested to see what her new student can do.

"Shadow Rose and Team RWBYS onto the battle platform please." She calls out as they move up onto the battle platform.

The rest of team RWBYS all brought out their weapons.

Shadow put on earbuds as he played music while he draws out his sword.

"It will be team RWBYS versus Shadow Rose." Glynda Goodwitch said.

All the students muttered as they were wondering when they had gained a fifth member and slight name change.

Yang charge at her little brother, he blocks her punches with his sword then Yang jump back as Weiss's Myrtenaster was thrown into the ground between his feet as he was encased in ice now unable to move his sword.

Blake rush at him swing her blade at him but he had managed to get free and jump back away from her, he quickly protected himself with his sword from Ruby scythe then he kicks her away as he blocks a strike from Weiss.

He quickly dodges Yang's left hook and kicks his older sister making her aura drop to red.

"Yang! You're out!" Their teacher yelled as Yang leave the battle platform.

'He got stronger while we were gone, guess he up his training.' Yang thought then warn her team, "Careful he a heavy hitter."

Weiss uses her glyphs for a speed boost as she charge at him when she was about to strike at him, he caught the blade of Myrtenaster in his hand.

"You and Blake are good but the three of you weren't who interest me in this fight." He said to her.

"If it not Blake or me then who?" She asked even though he couldn't hear her due to his earbuds but was able to read her lips.

"My twin sister." After he said that he punches her draining her of her aura.

"You're out Weiss!"

Weiss grumble as she walks to Yang who gave the 'I try to warn you' look.

He did a 'come at me' gesture to Blake with irradiated her, they both charge at each other with their blades colliding.

Ruby just watch her twin take out their team one by one and she knew he had no interest in them but just her.

Ruby use her speed semblance to get between them.

"Blake, I am going to have to kindly ask you to forfeit and let me fight my twin brother alone," Ruby said her tone serious which Blake never has seen this side of her.

She listens to her leader and walks off the battle platform as the two took some step away from their counterpart.

Shadow's Crescent Moon took on it scythe mode.

Yang looks at her little brother weapon, "Now that it just him and Ruby, he is taking it more seriously."

"How can you tell?" Weiss asked her.

"He has his weapon in it scythe mode." She stated.

They stare each down waiting for the other to make the first move.

Ruby use her speed semblance to charge at him, the sound of the scythe's collision could be heard.

Ruby fell on her back from a kick she receives from Shadow as Crescent Rose was knock out of her hand, Shadow drops down on her ready to strike but Ruby had quickly managed to reclaim her weapon and block his attack, Ruby quickly kick him off of her.

'He been training, I can tell that he improve.' Ruby thought as she counters and matches her brother attacks while she kept looking him straight in the eye.

Then there was a loud buzz when both their aura gauge was in the red zone, Glynda Goodwitch walks up to them.

"Excellent fight you two, you fought great even though the fact you weren't taking your older sister and other teammates seriously just your twin." She said, "Why is that?"

"It simple, she is the only other Scythe user here besides our drunk uncle Qrow that makes her my rival as I want to surpass my drunk uncle." He told her with a bored tone in his voice.

Shadow walk off the battle platform with Ruby as they go back to their team.

'Has losing mom as well what the White Fang had done to you affected you this much?' Yang thought in concern about her little brother as she remembers back to the time she had spied on her father conversation about the twins when her uncle has decided to train them on how to wield a scythe.

Flashback

Yang hide behind the couch thankfully the twins were asleep, she was listening in on her father conversation with her uncle.

"What did you need to talk with me about?" asked Taiyang.

"Your daughter Luna, she gifted, she quickly mastered the basics of using a scythe, she learning more quickly than I expected while Ruby has trouble with the lessons but that was to be expected from the both of them and I didn't think Ruby's twin sister would soak up the lessons far more quickly than she did," Qrow said.

"Is that it? So she a prodigy, just keep her at the same pace as Ruby." Taiyang told him, he wasn't happy that his daughters wanted to be huntresses well he could understand that two of his daughters want to pursue that but he rather keeps his daughter Luna living a normal life.

"Ruby is a lot like her mother in some ways but Shadow is the complete opposite, there is darkness in her, unlike Ruby who has inherited her mother light." Qrow says, "We better hope the light in Ruby's heart can dim the darkness in Luna's heart or Luna will…"

"She'll what?!" Taiyang shouted at him.

"Or she'll become like my sister." He stated.

"She is nothing like Raven! She is the child of Summer Rose. Yang is Raven daughter not Luna! " He exclaimed, "We just got her back from the White Fang! Qrow they turned my daughter into a wolf Faunus as a sick experiment to turn Human into a Faunus, whatever else they have done to her has mentally traumatized her to the extent that she uses her Gender Shift Semblance to become male!"

"Don't you get it, whatever they have done to her, Luna could possibly become something worse than Raven! All we can do is hope the light in Ruby's heart will keep Luna from going down a dark path!" The scythe master yelled at him.

Yang couldn't believe what she was hearing, so she decided that she sneak back into her room as her mind kept replaying what she heard repeatedly.

End flashback

Throughout their course of today classes, Yang had kept her eyes on Shadow thinking that he was going down the path that her uncle had predicted, perhaps there was something they can do to keep him from going down that dark path like her mother.

"Will you stay as Shadow Rose forever or will we get our Luna back?" Yang muttered to herself wishing she could see her little sibling in her actual form.

They can only hope their efforts can keep him from falling deeper into darkness.
