Basically, another alternative for the first motive.

I woke up and..... wait, this isn't my room..

I go to a mirror for a moment....

Is that Marvelous?!?!?? Wait.... unless this is.....

(Note: Any names with this font means that is the soul of the body)

Marvelous (K): Sayaka!!!!!

I knock at the door furiously..is this true!?!??!

Sayaka (Carl): Ugh... Marvelous.. don't yell at me like that... and why did you say Sayaka? I'm Carl.

Marvelous (K):...... look at your mirror.

Sayaka (Carl): What? Is there something wrong with my face?

He... she...I don't even know!!! Goes to check the mirror....

Sayaka (Carl): AAAAAAAAAAAAAAAAAAAA!!!!!!!!!!!!!!!

And then...."Carl" was awake.

Carl (Sayaka): What is going o-! WHY IS THERE ANOTHER ME!??!!??!!?

Sayaka (Carl): AAAAAAAAAAAAAAAAAAAA!!!!!!!!!!!!!!!!!

Marvelous (K): S-Sayaka!! Look at the mirror!!!

Carl (Sayaka): Um... okay Captain..?

Suddenly, someone kicked...MY DOOR!!!!!!!!!

K (Marvelous): WHO THE HELL SWAP OUR BODIES!!!!!!!!!!!!

I have no idea that my body can do that..

Carl (Sayaka): K's right!!!!! Our bodies were swapped!!!!!!!!!!!

K (Marvelous): I'M NOT K!!!!!!!!! I'M MARVELOUS!!!!!!!!!

Carl (Sayaka): Wait.... that means.....

MY LIFELONG DREAM CAME TRUE!!!!!

Marvelous (K): Yea, I become an alien!

K (Marvelous): Don't yea!!!! I'm short now!!!!!!

Carl (Sayaka): Wait, Captain, how did you know we were body swapped?

K (Marvelous): Two of my teammates were effected by this before. I couldn't believe it happened to me now.....

Sayaka (Carl): AAAAAAAAAAAAAAAAAAAA AAA AAA!!!!!!!!!!!!!!!!!!!!!!

Carl (Sayaka): CARL!!!!!! Stop screaming in my body!!!!!!

Sayaka (Carl): Sorry.

Suddenly, Yuga woke up.

Yuga (Maria): Uuu.... what's all the noise? Maria couldn't sleep....

Marvelous (K): .... check your mirror..

Yuga (Maria): Uuu? Okay.....

Suddenly... Maria's....? Door was busted open.

Roy (Ren): YUGA!! What's all the rackets going on here?!?!!

Maria (Yuga): .... Roy, who did you body swap with?

Roy (Ren): Body swap? What are you talking?!

And then..."Ren" woke up.

Ren (Roy): Good morning ev- is that my body?!?!

Roy (Ren): Oh my god he's right....we are body swapped.

Ren (Roy): What?

Yuga (Maria): Body swap! It's where your soul and conscious are inside of someone else's body and theirs is in yours.

Ren (Roy): Really?!!?!? Then who's body I'm in?!!?!!

Roy (Ren): Mine!!!! I'm Ren!!!! And I'm in yours!!!!!!

Flora (Ashlynn): Indeed. I'm Ashlynn!! Although, you have an amazing skin Flora.

Ashlynn (Flora): My, yours is more beautiful, Ashlynn.
