Under the campus of Beacon Academy is an underground vault. Inside are two pods containing Amber, the current Fall Maiden and Pyrrha Nikos, the Mistral Champion and the current candidate for the Fall Maiden. Beside them is Jaune Arc, the leader of Team JNPR and Pyrrha's partner as Professor Ozpin fights Cinder Fall, a student from Mistral but now reveals herself to be the mastermind behind the entire attack on Beacon.

Ozpin does everything he can to take down Cinder, but the woman dodges all of his attacks. She manifests a bow and arrow and takes aim.

"No!" Ozpin screams as she tries to stop her but it is too late. Cinder releases her hold on the arrow and lets it fly. As it flies, Cinder smiles, this was it. The power she has sought for will finally be hers.

… until it wasn't.

"Zoom Punch!" A manly voice rings out before an arm stretches to inhuman lengths and catches the arrow mere inches from reaching Amber's pod.

"Huh!?" Jaune said in clear surprise.

"What!?" Cinder screams out.

The arm retracts as a figure slowly walks out from the shadows. He is a man who looks to be in his early to mid-twenties, but what takes everyone back is how tall the man is. He has wild blue hair and wears an outfit consisting of a blue loose-fitted tank top with shoulder pads. He wears a pair of fingerless gloves that reaches his elbows along with a pair of wristbands. He wears gray pants along with a red belt and brown boots that go up to his knees. On his back is a backpack attached to the shoulder pads.

"Who are you!? Are you another of Ozpin's pawns?" Cinder growls.

The giant blinks in shock. "Oh! Where are my manners? Forgive me, miss." The man said with a particular accent. "I am Johnathan Joestar. And you are Cinder Fall, yes?"

'His accent reminds me of Velvet's.' Jaune thought.

Cinder's eyes widened. "How do you know my name!?"

"I believe this belongs to you." The gentleman doesn't answer as energy begins to build up in his arm. "Red Arrow Overdrive!" He throws the arrow back at Cinder who creates a pair of blades to block it, however, the moment they make contact, it unleashes an explosion that creates a smokescreen.

Jonathan moves to Pyrrha's pod and rips the lid off. "Careful, young lady. Here, let me help you." Jonathan takes Pyrrha's hand and gently helps her out of the pod.

"Thank you…" Pyrrha said.

Jonathan smiles and turns to Jaune. "You two should leave. As you are now, you cannot hope to best her."

Jaune's eyes widened. "But what about you!?"

"I will be fine. Now please go." Jonathan ordered.

Jaune reluctantly nods and grabs Pyrrha before they make a dash towards the exit.

The gentleman turns to the green headmaster. "You should leave as well, Professor Ozpin. It would be… unwise for you to die here."

Ozpin looks at the first JoJo suspiciously. "I am afraid I cannot do that. Someone must keep Amber safe, and I would rather not leave her in the hands of a total stranger."

Jonathan smiles. "That will not be a problem, professor. It's already been taken care of."

Before Ozpin can ask what that means, he sees Amber's pod suddenly sucked into the floor and disappears.

"W-What just happened!?" Ozpin asks in shock.

"Like I said, it's taken care of."

Just then, a torrent of flames rises behind them as Cinder walks towards them. She glares behind them and her eyes widen as Amber's pod is gone.

"WHERE IS SHE!?" Cinder demands from the two men before charging at them with fireballs.

Jonathan and Ozpin manage to dodge the flames and use another Zoom Punch to strike her gut, catching her by the long reach from their distance and the air escaping from her lungs stunning.

Jonathan looks at Ozpin. "Go. Help your students. I'll deal with her."

Ozpin nods. "Thank you, Mr. Joestar." He hurries off as Cinder quickly recovers.

"Now it is just you and me, false maiden. You and your mistress will not succeed so long as I am here!" Jonathan declares as he takes a fighting stance.

Cinder laughs. "You poor fool. What can one measly human do against us? Don't you get it!? You've already lost!"

"True. Alone, I could not hope to stop these monsters." Jonathan then smirks. "But I never said I was alone in this."

Cinder's eyes widen before lashing out in a rage and charges at Jonathan.

Jonathan's eyes brim with determination as he takes a deep breath.

Meanwhile

At the remains of the cafeteria, Blake struggles to move from the stab wound on her side delivered to her by her ex-boyfriend Adam Taurus. They then hear someone yelling for her as Yang appears.

"... starting with her." Adam says and moves towards her.

"No!" Blake yells.

"[Hermit Purple!]"

Suddenly, Adam is wrapped in purple vines that pull him back before throwing him across the burning room.

As Yang finds Blake, the two look to see two very tall men. The first is a muscular old man with short gray hair and he sports a thick, well-trimmed beard. He wears an outfit consisting of a fedora, a light, short-sleeved, buttonless shirt; khaki pants; dress shoes; and white gloves with dark wristbands.

"You young ladies alright?" The old man asks, but gets no response. "Um… hello?"

"Wow, you're tall!" Yang exclaims.

"Hehehe, yeah I know." The old man said. "Anyways, you two should get to safety. This is no place for little girls."

A tick mark appears on Yang's forehead. "What did you call me, you old geezer!?"

"A little girl. What are you gonna do? Hit me? You'd hit a defenseless old man?" He taunts her. "But seriously, you should leave. Your friend has a nasty wound and should get treated."

Yang sighs but then realizes something. "Wait, what about you?"

The old man looks as Adam slowly gets up and cracks his knuckles. "I'm gonna go and tame a bull."

"Wait! You can't! Adam Semblance allows redirect kinetic energy! You'll be turned to shreds!" Blake yells.

"No worries, ladies. I got it covered." The old man says, making the girls a little confused. "Oh, and the name's Joseph Joestar by the way."

Adam slowly approaches the trio.

"Your next line is…"

""Damn you, human! I'll kill you!/Damn you, human! I'll kill you!""

Adam gasps and quickly turns to see a tall young man with unkempt brown hair, parts of his bangs shooting outwards in spikes. His outfit can be considered minimal and pragmatic. He wears a tank top cut above the navel, gloves studded at the knuckles, fitting pants with a leather belt, and knee-high leather boots. Around his neck is a long, broad, striped scarf and on his head is a long, thin headband patterned with a row of tessellated triangles.

"Hehe." The man pulls out a baseball bat and it suddenly surges with energy and smacks him in the face with it, shattering his aura and sends him crashing to the ground.

"HOMERUN!" The young man exclaims.

Adam struggles to stand, part of his signature mask broken revealing the SDC seared on his face.

"Yikes! That must have hurt." The young man hissed.

Adam snarls and unsheathes his sword, ready to kill this bastard even though he has no aura.

Adam senses a presence from behind, and not wanting to make the same mistake, he quickly draws his sword and slashes the person behind him.

ゴゴゴゴ

To Adam's shock, his sword is frozen in place. He tries using more strength but it doesn't budge. A purple hand slowly appears but before he can look up, a purple fist collides with face.

"ORA!"

The strength of the fist was strong enough to not only shatter his aura, but send him flying out of the building and crashing in the front area of the academy.

The brown-haired man lets out a whistle. "Well, that was epic." He then turns to the person who did it. "You sure took your time getting here, kid."

The man turns to another pretty tall guy. He has dark hair, a strong jaw, bold eyebrows, and green eyes. His outfit consists of a modified trench coat-length black school uniform, with a tall, stiff collar, pierced on the left with a golden chain. Underneath, he wears a fitted, sleeveless shirt and a pair of slim-fitting pants of very short, sharp flares held up by two thin belts, often differently colored, patterned in a row of alternately colored tessellated triangles. He also wears a pair of leather shoes (presumably) without socks.

He wears a visored cap which is adorned near the center with a golden button and, on its left, a rectangular golden plate with a design of a flattened hand. However, what's most jarring is the fact that his hat seemingly merges with his hair making it look like the hat is his hair.

"Shut up, old man. You two ran off and left me to fight those black things." The black man scowled.

The man steps back. "Eek! Jotaro's face is scary!" He exclaims. "And what did I tell you about calling me old man!? Call me JoJo!"

Jotaro gives Jojo a look.

"Hey!"

Jotaro sighs. "Here he comes…"

Joseph walks up to them. "You could have saved me some? I wanted to teach that brat a thing or two about hitting a lady!"

"I told you to protect the girls, old man." Jotaro states.

"Well yeah. They're fine now! Well, except for the cat, we should probably get her to a hospital." Joseph said.

Jotaro adjusted his cap. "Yare, yare daze."


In the sky, Ruby was fighting against Torchwick. She was able to get Neo off the ship, but she was currently weaponless. In retaliation, Roman swipes Ruby causing her to lose balance and falls but manages to hang on the ledge.

"You got spirit, Red. But this is the real world! The real world is COLD! The real world doesn't care about spirit!" Roman exclaims as he stands over her. "You want to be a hero? Then play the part and die like every other Huntsman in history! As for me, I'll do what I do best: lie, steal, cheat and survi-!" But before he can finish, a Griffin flies with its maw open.

"DORA!" Suddenly something punches the Grimm away, causing it to collide with another Grimm before falling straight to the ground.

The two turn to see a young boy casually walking up to them, much to their shock, seeing that he just appeared out of nowhere. He is a tall, handsome teenage boy of average build. He wears a small stud in each ear. The feature most important to him is his well-maintained pompadour, something that Roman recognizes and is instantly taken aback by it. His outfit consists of a dark, modified school uniform of sorts. His jacket conforms to his body, extending to the middle of his thigh, accompanied by a pair of wide-legged pants. He keeps his jacket unbuttoned and pinned aside, revealing a light undershirt with a short zipper on each side of his chest. He has a number of metallic/golden emblems. On the left of his collar, he wears a modified anchor, and on his right a row of two small hearts. Pinning his open jacket to his chest on his right is a peace sign, and on the left is a heart. He wears a gold band at both wrists, above his sleeves.

"Man, that speech was so lame. Saying stuff about surviving when you were about to become bird food. Next time be more aware of your surroundings." He said.

Roman's eyebrows twitch in irritation. "Who the hell are you? And what the hell do you know? You're just so kid with an outdated haircut! Your mom must be blind or stupid if she lets you run around with hair like that!"

*Snap!*

"Oi… what did you say about my hair?" The young man asks.

"Uh oh." Ruby mutters as she can sense the rage he's emitting.

"Do I really need to spell it out for you, kid?" Roman asks. "Your hair! IT SUCKS!"

Josuke sends him a glare before a pink/silver hand appears and punches Roman without even realizing, sending the Gentleman Thief off the ship.

"Oh… oops." The boy said. "I'm sure he'll be fine."

"A little help…?" Ruby calls out.

"Oh! Don't worry, I got you!" He pulls Ruby back into the ship. "There. You okay?"

"Yeah." Ruby nods. "By the way, what was the pink guy you summoned? Was that your Semblance?"

"You… could say that. It's complicated." Josuke said sheepishly. "I'm Josuke. Josuke Higashikata."

"Ruby Rose. It's nice to meet you!" Ruby says and smiles.

'Cute.' Josuke thought. "Anyways, I think we should get off this thing. It doesn't look like it'll last much longer in the sky."

"*Gasp* You're right! I got to look for Yang!" Ruby then grabs Josuke. "Hold on!" The two then blast off in a fury of petals.


In the chaos, Emerald and Mercury were currently on stand-by while recording all the destruction per Cinder's orders as they watched up the top of a building.

"Do you think Cinder will be okay?" Emerald asks.

"Of course she's fine. This is Cinder we're talking about." Mercury said, not even bothering to look at her.

"But… she's fighting Headmaster Ozpin. He's a headmaster for a reason." Emerald points out.

Mercury rolls his eyes. "If Cinder wanted help, she would've said so. Besides, who would be stupid enough to stop us?"

"MUDA!"

"What the-!" But before Mercury can see what's making the noise, a yellow fist collides with his face, sending him flying straight to Emerald.

"Get off me!" Emerald yells as she moves Mercury off her.

ゴゴゴゴ

The green theft looks up. She sees a yellow, borderline gold, humanoid entity of slender build and average height floating off the floor. It has what look like ladybugs on both hands, and the oblong grooves across its body. Its head extends into pointed tips with the back of the head hollow, giving it the appearance of a crown. It has exposed eyeballs embedded in cross-like structure within slanted sockets. It has an extended ridge collar on the back of its neck and several indentations and various other patterns covering its body. In its chest, it has an inverted heart.

Overall, it was a freaky sight to behold.

Beside the creature is a teenage boy of average height and slim yet muscular build. He has golden hair of moderate length tied back in a short, braided tail, with three distinctive oversized curls arranged in a row over his forehead. He wears a pink two-piece suit outlined with green with a checkered coat tail and several ornate features, including wing-shaped emblems on the collars and a heart-shaped opening in the chest area. The most distinctive feature on his suit are the three ladybug emblems located on either side of his chest and directly below his zipper.

"So you are with Cinder Fall." He looks at them with visible disgust. "Scum like you have no right to harm the innocent for your sick pleasure."

Emerald's eyes widened. Where did he come from? How does he know Cinder!? She frantically gets up and takes out her guns. "Get up, Mercury!" Emerald yells but gets no response. "Mercury!" She looks at the assassin only to see his glazed eyes looking blankly at the sky. "The hell!?"

"That is part of my ability. He will be out of it for a while." The young boy strikes a pose. "My name is Giorno Giovanna. And I was sent here to stop this madness.


Qrow, Glynda, and the injured Ironwood were still fighting against the Grimm as they tried to reach the others while also being concerned for the Grimm Wyvern approaching.

"Leave me…. Get out of here." James told them.

"Stop talking like that, James. You're going to get out of this alive!" Glynda yelled at him.

Qrow strikes down Grimm, but this only causes more to take their place. "There's no end to them!"

Glynda slowly begins to panic as she uses her Semblance to push Grimm away.

"Glynda, listen to me…" James began. "I just wanted you to know that you're fantastic. Absolutely fantastic…"

"Didn't I tell you to stop talking!? You need to save your strength!"

Unbeknownst to the two, an Ursa Major pounces on the two.

"GLYNDA!" Qrow screams out.

Glynda holds onto James as she closes her eyes, ready to meet her end.

But the end never came.

Glynda opens her eyes and finds the Grimm to be trapped in blue strings. James wastes no time and shoots the Grimm square in the head, killing it immediately.

"Hey, you seem to still be kicking despite looking like shit." A female voice comments.

The three Huntsmen turn to see a young girl of above-average height and slim to athletic build. She wears her hair in two "layers": A dark base including two large buns atop her head and a short length going down her neck; above which, lightly dyed or bleached, she keeps a plait or braid that winds around both buns, joining in a short length at back, and bangs that frame her face.

"Young lady, while we are thankful for helping us, you should head back to the safe zone." Glynda told her.

The young woman gives the deputy headmistress a look before she scoffs. "You're welcome." Her voice was dripping with sarcasm. "And I'm not a student. I'm 19."

James slowly aims his weapon at the girl. "In the name of Atlas, I order you to identify yourself at once."

The girl glares at the general before unleashing more string upon the general, tying him up before he is pulled before the girl.

"James!" Qrow and Glynda yell as they read themselves for a fight.

"Listen fucker. I don't know who the hell you are, but you have a lot of nerve holding me at gunpoint, especially when I just saved your life. If I were you, I'd be more worried about the people instead of my fucking identity." The girl states.

Qrow lowers his sword. "She's right, Jimmy. We have bigger things to worry about."

James looks at the girl before lowering his weapon. The girl scoffs as she commands the strings to let him go.

"My name is Jolyne Cujoh. And I am here to help you deal with your shadow war bullshit." Jolyne says with a sigh. "Yare Yare Dawa."


In the battlefield below, Weiss Schnee along with other students struggle in their fight against the Atlas Paladin. "Damnit, I'm not dying here." Weiss activates her Semblance, slowly summoning an armored knight only for it to be crushed by the foot of the robot before she collapses from exhaustion.

The Paladin aims its weapons at Weiss, however before it can fire a bullet zips past them and strikes the mech blasting off a large zone on it and causing it to be destroyed.

Everyone was shocked that the mech they had such a hard time with was quickly destroyed.

They hear the sounds of a horse behind them, and to their bewilderment, they see a young man on a horse. He has light eyes, and light, shoulder-length hair curling upwards at its ends. He wears a knit cap, printed with many small five-pointed stars. His hair sticks out of holes on either side of the top, taking a shape like short horns. A horseshoe hangs from the front; framing an image of the dark silhouette of the profile of a horse's reared head.

His outfit consists of similarly star-patterned pants; of a piece with footwear bearing spurs. He commonly wears a light-colored, hooded, short-sleeved top; printed with thick lines in the approximate formation of a harness. A long feather emerges from under the back of his collar; and he wears wrist cuffs patterned with stars and stripes.

"Is everyone okay?" The young man asks.

"Who are you?" Weiss asks, surprised by his sudden appearance.

"My name is Jonathan Joestar, but you can call me Johnny. And I'm here to help." Johnny said as a strange red creature appeared floating beside him.


Up in the sky, the Grimm Wyvern was closing in on its destination as it was ready to cause death and destruction.

But before it could get close to the tower, a small bubble-like object with a star symbol on it attached itself to the monster's face, and suddenly cried out in shock as it suddenly lost sight.

This causes the Grimm to crash to the ground, thankfully to a non populated area.

The camera then zooms out revealing someone standing on a roof. He has black hair and wears a tasseled "Dixie cup" sailor cap. He wears a sailor suit, cut with a wide neck and above the navel, a neckerchief with a button resembling a slotted screw head, large emblems of an anchor on his right side and a compass rose on his left, fitted pants with a belt, and a pair of high-top athletic shoes.

"I can't beat that thing. But I can steal its sight thanks to [Soft & Wet]'s Plunder Bubble." Josuke Higashikata, the eighth JoJo, comments as he watches the dragon writhing on the ground.

Later

The Grimm have been eliminated and the White Fang has been driven away. Atlas artillery managed to kill the Wyvern before it could get up.

Ozpin, Glynda, James, Qrow along with the students stand in front of the newcomers.

"On behalf of the kingdom of Vale, I thank you all for your assistance. If it wasn't for you all, the assault would have resulted in uncountable loses." Ozpin states.

"Eh, this is nothing! We're used to fighting more dangerous enemies!" Young Joseph exclaims (AN: I'm just gonna call him JoJo and the old man Joseph to set them apart).

"I… see." Ozpin didn't know what to say to that.

Jotaro steps forward. "Regardless, I think it's time you fill us in on what is going on here. And you better not lie to us."

Ozpin sighs. "Very well."

"Ozpin, you can't be serious! We don't even know these people or where they come from! For all we know, they could be working with her!"

Ozpin's face twitches. "For once, James, control your paranoia! I am on my last nerves here and I do not need to hear your nonsense right now, understand!?"

James steps back, shocked that his old friend would snap at him like that.

"Damn…" Qrow mutters.

Ruby frantically raises her hand. "Oh, oh! What was that pink arm you summoned?"

"And those purple vines?" Yang asks as the other students ask the group a ton of questions.

"Alright, alright, calm down. One at a time please." Jonathan says as the voices die down. "As for your question, it's a long and bizarre story."

?

In an unknown place, a figure watches everything that is transpiring through their screen.

"Good. Everything is going as intended. This time, fate won't have its way. Not this time." The voice said. "Now, what will Remnant do, now that a third player has joined the war?" She chuckles. "This will be fun."


Author Notes

Here's another chapter. This one is interesting. Never thought I would tackle JoJo so soon. It's a little short, but this is more or less a one-shot, for now at least.

I'd like to thank triscythe59 for the brilliant idea. He makes a lot of good reaction stories.

As always with new stories, if you guys like it then it stays and I'll continue writing for it and if not then to the dumpster it goes.

Peace~
