(I know I'm still working on my Persona book, but I thought I publish this chapter because why not, anyway enjoy!)
Donnie and Mikey were heading back to the lair with Celica and Minerva, what they didn't know was that Platinum was following them.
Sena: Luna are you sure it's a good idea to follow them?
Luna: Of course it is Sena, Master Jubei might be there.
Platinum looked down to make sure no one noticed her.
When the coast was clear she jumped down into the sewers
Platinum quickly held her nose to avoid the stink of the sewers.
Sena: Ugh... why does it stink down here?
Luna: Shut it, Sena! come on we're almost there.
Platinum had to be very careful following the two turtles, one wrong move and she would be busted.

Donnie and Mikey arrive back at the Lair with Celica and Minerva with them,
Donnie: We brought Celica back,
Tsubaki: oh thank goodness, we were so worried!
Donnie: You feeling better Tsubaki? After what you witnessed?
Tsubaki: yeah. Much better.
Donnie: Where's Ragna?
Tsubaki: Oh Ragna went out to get some fresh air. anyway, training's about to start
Donnie: alright, Celica wanna watch us?
Celica: Sure!
Minerva: ...
Celica and Minerva head over to the training room
Kokonoe: Oh yeah Raph your weapons are repaired
Kokonoe sent Raph his newly repaired weapons by sending and turning the hologram into weapons.
Raph: Wow, thanks.
Once everyone was in the training room Platinum came out from hiding and looked around in amazement.
Luna: Ok I have to admit this place is impressive.
Platinum looked over in the kitchen and saw a leftover slice of pizza.
Sena: Luna don't tell me your going to steal that are you?
Luna: Hell yeah I am!
She carefully tip toes over to the slice of pizza before she snatched it from the kitchen table and took a bite of it.
Platinum then walks over to the training area with a slice of pizza in hand hides behind a wall then peeks from behind the wall.
Luna: That rat guy reminds me of Master Jubei.
Sena: Quiet Luna we don't want them to hear us.
Platinum quickly hides behind a wall before Leo looks over.
Noel: Something the matter Leo?
Leo: I Could've sworn I heard something.
Sena: That was close...
Luna: Ugh! It chaps my ass just thinking about it! How dare that Rat guy be so happy talking about you, Michelangelass
Luna then had an idea as a lightbulb appeared above her head.
Luna: I got it!
Sena: What's your idea, Luna?
Luna: Once the old man leaves the room we'll attack the pervert from behind,
Sena: Which one?
Luna: The orange one idiot!
Splinter: Noel will be paired with Michelangelo against Raphael and Donatello
Noel and Michelangelo looked at each other with a surprised look, they had never been paired up before.
Noel took out her Nox Nyctores and pointed them at her opponents
Splinter: Hajime!
As the match started, Noel fired her guns at Donnie.
Noel: Bloom Trigger!
Noel fired shots from Bolverk.
Donnie: I better be careful against Noel's Nox Nyctores
Donnie thrusts his stuff forward but Noel ducks under and gets close,
Noel: Spring Raid!
Noel does a flash kick. Knocking Donnie's bo staff out of his hands
Makoto: Noel Behind you!
Raph already beaten Mikey, uses his sais to disarm Noel as her Nox Nyctores fall to the ground.
Raph: What are you going to do now without your guns?
Noel's mind: Guess I have no choice.
Noel: Summoning Lux Sanctus!

Makoto: Oh boy, you guys are screwed...
Donnie: I've never seen that form before.
Mu-12: Murakumo Unit... Activate!

Raph: What kind of outfit is that!?
Mu-12: don't hold back.
Mu fired her bladed wings at Raph,
Raph tries to get close to her while dodging her bladed wings. but Mu-12 uses one of her attacks
Mu-12: Origins!
Mu-12 projects a barrier around herself  knocking back Raph,
Mikey: Woah Noel looks... different!
Kokonoe: That is Noel's true form, She was once brainwashed by Terumi and was called Kusanagi the God Slayer. She hated the world and only knew destruction until Ragna saved Noel at the cost of his left arm. thankfully I gave him a new one.

Mu-12: Arrows of Heaven!
Mu-12 fires an arrow projectile which Raph deflects it with his weapons.
Raph then jumps in an attempt to stab the God Slayer but Mu-12 binds Raph in place.
Raph: wha-? Why can't I move!?
Mu-12 then summons 8 giant swords to surround Raph.
Mu-12: Wisdom of the Divine!
Mu-12 then strikes down the 8 swords at once
Splinter: Yamē!
Mu-12 returned to her original form.
Celica: Let me help you guys.
Celica used her healing to patch Donnie and Raph.
Raph: You never told me Noel can do that!
"Thank goodness I was paired with Noel." Mikey sighed in relief
Platinum carefully crept up behind the party turtle
"GOTCHA!!!" Luna yelled as she tackled Mikey to the ground from behind.
Mikey: W-Where did you come from!? Let go of me!
Platinum: I did it I got him!
Raph: Hey what are you doing here?
"Oh uh... we just got lost and stumbled onto this place." Luna lied
Sena: Luna your a terrible liar,
Leo: Huh? Who are you talking to?
Sena: oh I was talking to Luna.
Donnie: How did you know where we lived?
Luna: We kinda... followed you. But it was Sena's idea.
Sena: What? How was it my idea?!
Donnie: You followed us!?
Leo: Wait, Mikey, you know this girl?
Mikey: yeah...
Jubei came out and saw Platinum, he instantly recognized her.
Jubei: Platinum?
Luna/Sena: Master Jubei!
Platinum ran over to hug her master after she lets go of Mikey.
Leo: Seems you know this kid Jubei.
"Kids" Jubei corrected.
Jubei: Turns out Platinum has a split personality first there's Luna the rude and brash type and Sena the polite and understanding type.
Luna: We've been looking for you! Where have you been?
Jubei: I guess you haven't been caught up to speed yet.
Jubei explained everything about what happened.
Luna: huh. So basically this Shredder person is the guy that we need to take down to get back home. Yeah... Master Jubei let's kill this Perv,
Mikey: Wait! You don't want to kill me!
Jubei: Now now Platinum let's calm down. Why don't you have a sparring match with either of them?
"Oh whatever, one of you guys can take me on, Be my guest" Platinum devilishly smirked at the last sentence.
Jubei: Splinter I'll take it from here.
"Very well," Splinter said as he returned to his room
Jubei: so who's going fight Platinum?
Donnie: Mikey will take her on.
Mikey: Wait what?
Donnie: You clearly have a rivalry with Platinum. And the fact that she stole your pizza.
Mikey: Yeah no thank you, I can't hit a little girl!
"Not even for... this" Luna Taunted as she held out a slice of pizza.

Mikey: Oh your on Platinum!
"Don't blame me if you lose, pervert!" Luna taunts as she summons Muchorin.
Mikey: stop calling me that!
Jubei: Begin!
Platinum: Magic Missile!
Platinum fires a cat missile as Mikey dodges it.
Platinum turns her Muchorin into a frying pan as she whacks the prankster with it.
Platinum: This is for calling me a Pizza Hogger!
Mikey: Since when can your weapon do that!?
"Oh no, is the big bad pervert having a hard time against a magical girl?" Platinum taunted
Sena: Luna, You're getting cocky.
Raph: Now I see why Mikey can't stand this brat.
Luna: Hey don't forget Sena's here too!
Sena: Luna watch out!
Platinum looked ahead of her and saw Mikey managing to land a hit on Platinum, which knocked the pizza out of Platinum's hand. Mikey catches it with his hand.
Mikey: Thanks for the pizza kid
Luna: Hello! Sena is present you know!
Mikey: Oh right my bad.
Luna: Ok... You asked for it you perv!
Platinum: When Luna and Sena's spirit...
Platinum immobilizes her opponent as her outfit changes to white and gold

Platinum: Unite as one! We'll crush all who dare oppose us..! Take...
When Platinum is about to use her ultimate attack, Jubei stops her by gently chopping her on the head.
Jubei: That's enough Platinum. The Winner is Michaelangelo!
"Master Jubei, I was about to win!" Luna complained.
Jubei: You were. But using that attack was against the rules.
"Take that Kid...s!" Mikey Corrected
Luna sticks her tongue at the orange headband turtle.
Platinum then noticed that Noel, Makoto, Tsubaki,
Platinum: where are you guys going?
Leo: We're going to find Ragna, Noel you're with me, Donnie goes with Lambda and Tsubaki, Raph, You'll be going with Platinum. And Mikey will head out with Makoto, Celica. you stay here.
Luna: Can't I go with you, Master Jubei?
Jubei: Sorry but I'll be looking for Ragna as well so I'll be pairing up with Leonardo and Noel as well.
"You can't do this to me, Master Jubei! It's against the rules you can't take me with him I'm a magical girl! This is illegal, it's totally illegal it's gotta be illegal! Wait! WAIT!!!!" Luna whined.
Mikey: you're going with Raph and there's nothing you can do about it!
Luna: Please don't make me go with a creep like him! PLEAAAASE!!!
"Come on Let's go you runts," Raph said as he carried Platinum over his shoulder.
Luna: No, no put me down put me down!
Try as she might, but she couldn't escape Raph's strong grip while everyone else headed out.
