In the ghost zone.

In the air the ghost of summoner rose was flying she had black bird wings in her normal outfit form her life her skin grey her eyes still silver but now it was solid with silver mist coming out, her ears pointed. Her hood ripped and burned looking more like a cape, her high heel boots landed on ice as she adjusted the sword sheaved at her side.

She then knocked on the door of an ice manor molded after the Schnee manor.

Nicholas Schnee now having pale ghostly skin answered and said, "Oh summon Rose what can I do for the leader of the Fury's and head maid of the king of the ghost zone!?"

The silver eyed warrior put her hands together nervously , "samara's dropped her ball and thanks to our island being higher then yours it crashed into your upper towers window So as head maid I have to ask for it back!"

the old man laughed as he said, "Oh don't be silly this reminds me if the times is should have had with my grand children" he said sadly, " stupid cancer anyway the roof has a hatch for taking off you can fly up and in to get it!"

rose flapped her wings saluting, "thank you sir!"

the old man then went in to see his wife pale Green skin blue ghostly hair and eyes in a simple white snow like dress and white sleeveless glove nana Schnee adjusted her long flowing hair, "What's up honey."

old nick then said, "Nothing my darling Anywyn the neighbor girls dropped her ball again"

outside Summer was flying with the ball, "I am the leader of the furries female angels of vengeance born form the souls of women who fell in battle broken hearted yet I most act as nanny! Stupid king!"

She then stopped as all the light vanished, "great Danny is using void again! Just hold still and wait for him to turn light back on around him or for him to move out of range what old headache of his is it now?"

Meanwhile on earth.

the next day in the forest Jaune was with Pyrrha he used his shield with it's hard light expansion powered by his own ice powers to block a death stalker stinger freezing it n contact making it shatter.

First he had Missed his chance to partner with yang his girlfriend and the only one he could be himself around because she bumped into blake before his invisible ass could get to her. Now he had an over grown bug and thanks to the human beside him he couldn't go ghost.

it would be unneed as it was just a grimm but he really wished she was gone so he could just ectoblast it.

the red head held her weapon in rifle mode shooting it in one of the eyes, making the blonde say, " yeah now do that nine more times!" he said holding his sword out to block a clack strike. He covered the blade in green lighting using his ghost powers again but disguised as dust!

the blade went into a crack making it roar as he jumped back.

Unknown to them Salem was watching through the nevermores eyes for years she was puzzled by this phantom fellow. Sense he easily handled her dragon she looked into it, Stories of ghostly warriors appearing to slay grimm spread like wild fire as new legends. She knew this where true as she had images of all this so called ghost slaying her pets.

She put her finger tips together it wasn't till earlier this week she finally found out why she couldn't find them! She looked at a crystal ball of Jaune appearing form a ghost portal in human form in the middle of nowhere before going ghost to fly off. " they aren't completely dead!"

She was puzzled holding her chin! They had aura, She had seen other ghosts one of a little girl didn't have aura just this ecto energy stuff. She knew their was true ghost and ghost that lived. It was a puzzle all she knew is even while pretending to be human the one she watched outmatched her Grimm.

in the fight Jaune ducked turning intangible for a moment while still visible while the red haired Woman would just see him avoid a claw strike she saw the claw pass through his head. "The dead ruining my plan! How ironic this only start as I want the dead to return to the land of the living now I don't! be careful what you fucking wish for! It might just bite you in the got time ass!"

In the fight Pyrrha was calling out, "We need to fall back! " Jaune held out his shield form it firing off a green burst of energy, it could do this with dust but he was just using his ecto energy for the same effect. The energy blast hit the thing's cracked claw shattering the shell around it and burning the flesh inside away leaving it dissolving at a claw point enraged.

The blonde turned to run as he said," fine but we do it my way!" he said putting his sword in his shield to pull out something and he throw it making an energy shield dome around the thing leaving it trashing making it close. "Thank you grandpa!"

Pyrrha watched the dome shrinking as she said," the hell is that?"

the blonde said, "my grandpa fenton's Fentonworks crush shield. One use only makes a small energy shield that shrinks a little pit as it's power dies crushing what's inside if it can't brake out! and as the device is out side of it yeah going to hurt! I'll have to tell him his protype works!"

Pyrrha blinked She liked Jaune he didn't treat her like she was a queen didn't hear of her fighting records and now she was learning his grandfather was a very skilled weapon's smith with a specialty in defense.

She looked to his shield it was an odd weapon but form what she had just learned makes sense.
That is when he jumped up grabbing Weiss and using those hard light panels to glide them down to safety at the ruins below.

Once landed he set her down and Weiss blinked and said, "thank you very much!" She said bowing in thankfulness. She could have been injured so she had to thank him for it.

Yang was spinning her relic around in her hand, "yeah that seems to be what he's good at!" she sounded jealous.

Nora then point and said, "and he floats through the air with the greatest of eases Am I the only one sane here!" She said pointing it out. Jaune then gave her an eye flash of green and she said," HIS EYES CHANGED!"

Ruby then blinked," so when yang use her semblance her eyes change and he's semblance is already similar so nothing weird their!"

Later on when the nevermore came back Jaune touched Ruby's back to boost her aura as she did her run to cut it's head off.

it all seemed over but unknown to them the death stalker was still around it's armor cracked as shit. The crush shield almost got it it was missing an eye it's left claw and stinger it was pissed, and fearful of that blonde, but it's master ordered it to find him alone! To force him to change into a ghost.

as the sun was setting.

Yang was outside with Jaune and said, "And while I am happy to be on a team with my sister sucks I can't be with you!"

the halfa then spoke up, "you're telling me! dad told me not to go ghost or reveal myself unless it was against a ghost!" he then had a chill as his breath was seen.

in a moment he changed and turned to see a ghostly shadow hovering it had no face or eyes and looked to be falling apart with trails of mist spear in hand as it charged only for Jaune to hit it with an ecto blast knocking it away, "Relax it's just an echo!"

his girlfriend blinked as Jaune said," Oh right. There is something called the unworld when a soul is sent into their it's aura or ecto energy is ripped away along with form left in a black endless void alone with their thought for all of eternality!" Yang's eyes widened as he said, "An echo comes to be form the stripped away aura or ecto energy they act on instinct!"

he watched it fading away "they can't regenerate or restore energy so they normally don't last long! And act on instinct! As the school was build on a battle ground form the great war, One can say it's an echo of a solider and it only attacked out of instinct!"

That is when the death stalker form earlier appeared and Jaune said, "need to tell grandpa to adjust the power on that crush shield grenade oh well Relax I can handle a grimm easy!" he waving his hand making the things eyes freeze and shatter.

the grimm struggled unable to see Till it touched the echo and the Grimm screamed as the echo phased in as Jaune said, "Wait is that echo overshadowing the grimm!?"

Yang walked back as her eyes widened as the grimm changed the stinger regrow now made of sloppily shaped green crystal. The red became green glowing with ecto energy. The head and claws vanished replaced by a humanoid torso in scale while the left hand was a claw the right hand was a sloppy covered in mist three fingered hand the head was now a gladiator like helmet made of grimm bone crest and multiple eye holes.

jaune blinked, "I knew echos could merge are be absorbed but…. One merging with a grimm… A grimm ghost hybrid this is unheard of!" he said smirking at it.

Yang hide behind her boyfriend as she got her gauntlets out, "less geeking out at it more kill it with fire!" her weapons still had the silver and green colors but now had metal finger covers with green glowing spikes on them, "well I wanted to test out this mods your grandpa made." Even the fingers were tipped in green spikes
