At the Flaming Foundry, Demon Bull King and Princess Iron Fan watches as the bull clones continued mining at the bottom of the trench has the top of what appears to be a tomb of some kind is revealed.

As the demon bull clones dug into the ground around the glowing blue capsule, as one struck down there was suddenly a large explosion of blue powers, blowing away all the bull clones as the chained prison was revealed.

It was a tomb.

Princess Iron Fan grins as she watched one of the bull clones managed to make a crack close to the tomb which released a blast of blue energy that dissipated the stone around it to reveal the entire coffin.

Soon the entire Demon Bull family stood in front of the tomb has whispers echoed and blue chains surround it. Demon Bull King approaches the coffin. "Finally." He reaches out a hand to open it but was blocked by a mystic barrier.

The bull king looked in shock before anger took over his face and he tried to break it open. "Another infernal obstacle keeping me from my destiny!" A huge blast occurred when DBK's fist collided with the barrier once more but it seemed to haven't make the slightest dent on it whatsoever.

"Patience, my love." The demoness calmly assured her husband, DBK got down to her level growling angrily. "I've been patient long enough. I need that power!" PIF looked at her husband in disbelief and indignantly, he has never in her life raised his voice at her before.

She huffed and walked towards the tomb. She placed her hand upon the seal over the lock and examines it. "The power that crafted this tomb, is beyond my skill. Without an artifact of equal strength, there's nothing we can do..." Princess Iron Fan lets her hand fall.

"In other words, we're locked out."

Red Son then approached his parents with a confident smirk. "Not for long." He then displayed his holographic screen has it displayed over the lock. "All we need is a key, And look what I found."

"Hold still MK, I'm almost done."

Tang instructed while combing the teens spikey hair down to make it look neat for today's special event.

"Sorry Tang, I can't help it, I'm just so excited!" MK exclaimed, bouncing up and down from her seat.

"Okay. So as of all the heroic antics I've done today, can you believe that the Mayor is coming by to the shop! I know right!? I can't believe it myself."

"All done!" Tang placed the comb, shows her a mirror. "What do you think?" Tang had put her hair up in two buns with flowers clips to hold it in place.

MK gasped in awe, eyes sparkling as she hugged Tang. "I love it, thank you Tangy!" She nuzzled his chest.

The scholar couldn't help but let out a whimper, "Oh my sweet little girl, you're growing up so fast." He let's out a cry, coddling her.

"Hmph?? Tangy, your smothering me." She muffled through his clothes.

He sniffed, wiping away his tears. "Alright, c'mon everyone is waiting for you."

The Mayor was a rather...strange man with pale ivory skin, ash brown hair with a slight gray streak and piercing ice blue eyes. He wore a tailored black tuxedo with a light blue button up underneath. The mayor was standing on some crates in front of a podium, MK beside him, he clears his throat before speaking.

"Thank you for this amazing turnout!" The mayor said with a big smile.

"Alright! Let's hear it for Monkie Kid! Hero of the city!/My bestie!" Mei cheered, grabbed a nearby chair and smashed it on the ground.

"As mayor, I hereby give monkie kid the key to our fair city." He turns to MK, shakily handing her the key. MK took the key in her hands, her eyes suddenly became blank as a blue aura surrounded her, bursting from her body.

"Thank you Mr Mayor. Umm...what does this key do, exactly?" Mk asked.

He chuckled "Oh, you'll love this, It has the power to open anything!"

"Oooh, anything?" asked Mei, getting into the mayor's face. "Like a pet shop full of puppies?"

"Yes! Or the door to a lion's cage, or an orphan's piggy bank, an imprisoned mystic power source, or whatever you'd like!" he chuckles nervously, turning to look at MK. "Today, you can do no wrong. You've got my permission, 'cause I'm the mayor!" He cackles menacingly, disappearing into blue smoke.

"Um...Okay?" MK sweat dropped at the Mayor's behavior.

"Huh, I'm starting to think...maybe that ain't the mayor." Mei said.

MK turns her attention back to the key. "Wow. A key that can open anything." She and Mei stared at it, looking at the other with wide smiles. "Are you pondering what I'm pondering, Mei?"

"Sure MK! But...I don't think Jack DeSena's available in this AU."

MK held the key in front of her as Mei stood behind her. The key activates and a line of doors appears before them. "You ready for this?" MK asked Mei.

She laughs, grabbing Mei's hand as they head through the door. First the arcade, where the two played monkey mech. Then a truck full of puppies, along with other dangerous animals.

They went everywhere; the shoe store, back to the anti-gravity arcade to party, even the weather station. They were having a blast, not a care in the world. MK turns to look at the key, holding it to her temple and gasping, an image invading her mind.

"Mei! Mei! Okay, hear me out. We knew the key could magically unlock anything."She stated.

"But maybe, it can also magically lock anything, too!"

"You literally just described all keys."

"Yeah, yeah, fine. but do you know what this means?" MK asked.

"Having this key, this power. it's so much responsibility," she said before grinning. "But I know what we need to do."

Back at the shop, Pigsy came back from the shopping district, humming to himself. He placed the bag of groceries down, pulling out his keys, unlocking the door. But when he tried to open it, the door wouldn't move.

"What the-" He grits his teeth, rolling up his sleeves and trying again. the door still wouldn't open.

Crack!

"Ow! my back!" Pigsy growls, rounding the back of the shop, hitting a pile of trash in the process. He grunts, kicking at the back door as he fell to the ground, struggling to open the door. "Let me in! let me in! who's in there? let me into my noodle store!" He shouts at the top of his lungs in front of the shop.

There was the sound of snickering, looking up at the balcony of Mk's apartment to see Mei and Mk, snickering and laughing. "Ah, I wish we had this key all the time, I don't think I've had this much fun in...forever!" She chuckled.

"Ooh! Maybe that key has the power to open...your heart~" Mei said in a teasing manner, wiggling her eyebrows.

MK yelped, blushed madly, "M-Mei...I dunno what you're talking about." Mei elbowed her bestie. "Ow!"

"C'mon MK, when was the last time you've had a boyfriend...or girlfriend?" She leaned against the railing on her balcony. "Gotta be someone that's caught your attention." MK fidgeted with her hands, shuffling her feet nervously.

Lately she's been receiving gifts and flowers and she's got no clue who that is. But she had to admit, so maybe someone did caught her eye.

"I dunno, maybe...someone has already has?" The dragon girl gasped in excitement, shaking her shoulders. "Who is it? Tell me, Tell me!"

"Wait Mei! I don't really know if-" MK was about to speak, but froze when the scent of smoke fills her nose.

"Mei, Look out!" An explosion went off, the two were thrown back by a burst of fire. MK groaned, looking up to see Red Son emerge with a grin. "Noodle girl! Finally!"

"What the! What the hell are you doing in MK's house?!" Mei cried.

"You better not have gone through my drawers, you little pervert!" MK yelled Red Son scoffed, pink in his cheeks.

"H-How dare you!? Do you know how long I've been waiting here for you?! Your house is...depressing! A lady such as yourself shouldn't be living in such a hovel. But...I'm going to need that magic key." He smirks, lifting his hand as it engulfs in flames. The key suddenly coated in red, levitating into the air as Mei and MK tried to grab it, but failed.

"Yoink! so long, ladies!" Red Son teleports into flames, flying past the two and into his truck, laughing menacingly.

"Oh no! the key!" MK cried out. Mei frowns and whistles, her motorcycle appearing overhead, as she jumps on.

"Wait for me!" MK calls after her as she drives off.

"No, please, It's all good! I definitely don't want a ride," Mk frowned, summoning her staff. "It's totally fine!"

Meanwhile, further down the city, Red Son's truck is seen hitting every car he passed by.

'Yes! I have the key, and soon the mysterious ancient power will be ours to command!' Red Son thought excitedly in his head, then his mind began to wander as he thought of MK being all over him.

'Ooh, Red Son your so mighty and powerful~'

'Oh I know I am, Noodle Girl~'

He sighed lovingly in his daze, Unknown to him, green lightning is seen following behind him. "What the?" It was when he saw the motorcycle jump into the air that he noticed Mei had caught up to him, causing him to gasp.

Mei grins, pulling out her dragon sword. She lands in front of him, making the fire demon growl in frustration. "Can't you and your little peasant friends let me plot in peace just one time?!"

Mei lowers down her hologram, removing her helmet, before giggling as she turns to Red Son "Oooh, Red flames are so cool! Wanna see some green ones!" She grinned.

"Say What?"

With that, Mei cranks the gas as she zips around the truck. Far behind her, MK swung on her staff when she noticed Mei and Red Son. She loses her balance on the staff, nearly falling until the staff stopped, flinging her into the air.

"Stop moving around!" He shouted in frustration.

"Does it get boring? us beating you all the time?" Mei taunted, getting closer to the truck. "You know we're gonna get that key back, right?"

Red Son growls in frustration, his hair and eyes bursting into flames as he jabs into the panel, slamming his foot on the gas. He swerves the truck to face Mei, descending himself down as the truck shifts, the top flying off.

"Whoa!" She cried, she swerves, dodging the top and cranks the gas, jumping off the bike. She swung her sword, cutting through the parts, landing on the ground.

"Ha! So long, dragon horse girl!" The fire prince laughs, looking over his shoulder. "Here's a tip. Next time, pick one animal and-" His words are cut short, as MK appears above him, crushing the fire demon with her staff.

Red Son grunts, tumbling and rolling to the ground, dropping the key. MK lands in front of him, picking the key up.

"So, looks like you've reached the end of the line, Red Son. What the heck were you even gonna do with this thing, anyway?" MK asked, eyeing the key.

"Why spoil the surprise?" A female voice said.

Mei and MK turned to see Princess Iron Fan appear, smirking. "Now, hand the key over and stop wasting our time."

Mei and Mk shared a smirk, charging at her. Princess Iron Fan smirked, blocking Mk's staff with her fan as Mei tried to swipe at her from behind, but she easily dodged it. Mk tried to kick at her but she used her fan to push him away. The three kept clashing, until Princess Iron Fan used her fan to pick Mei and MK up, throwing them across the street and into a building.

Red Son quickly got up, grabbing the fallen key. "Come along, Red Son. We have things to do." Princess Iron Fan said.

"Thanks for the key, ladies!" Red Son exclaimed.

Princess Iron Fan facepalms at her son's childishness, the winds covering their forms, as they disappear into the sky.

Mei groans, sitting up and looking around.

"Did they get away with the key?!" sliding off the building, MK fell face first into the pavement with a groan, sitting up.

"Yeah, But what I can't figure out is, why?" She wondered.

"You know, I'm beginning to think that a key that can open any door is sounding incredibly dangerous, we have to keep our guard up." Mei said.

"Something tells me that you're absolutely right Mei."

Back at the Flaming Foundry, Demon Bull King holds the key in hand. The key shifts, inserting itself into the lock with a twist. The tomb unlocks, cracks of blue light appearing. There was a powerful gust of wind, knocking back Red Son. The doors of the tomb open, as mist filters out. Red Son gulps, slowly walking into the tomb.

"Bones? I-it's just...bones?" Red son gasps, a chill rolling down his spine, kicking his leg. He looked down to hear hissing and tried desperately to kick off whatever was on his leg. Both Princess Iron Fan and Red son turned when they heard Demon Bull King laughing. His yellows fade to blue, absorbing the mist surrounding him.

The fallen bull clones suddenly come to life, their eyes glowing blue.

"Freedom!!"
