(Author's Note: Ah yes. The hardest chapter for me to make sure who switched body with who. Don't worry, guys. I'll give my best!)

Person (Other Person's Soul)

Third Person's POV

The episode starts showing Ryuseidou, where Poppin'Party practice their song most of the time. Hokago Tea Time was also there knowing that they should also make a new song at least instead of drinking tea all of the time.

It's evening time and the girls just finished practicing their new songs.

Arisa: Kasumi! Hurry up already.

Kasumi: Hold on! I'm coming.

Yui: Yay! We finished our new song!

Ritsu: Alright!

Azusa: Well, not really complete.

Kasumi: Today was tiring, is it?

As Kasumi stepped on a stair, she slipped as she pulled Arisa's sleeves. This, of course, cause the other to also tripped down and fall together from the stairs.

Rimi: Arisa-chan...

Tae: Watch out!

Saaya: Everyone, what are you- woah!

Ritsu: W-Waaaaaaah!!

Mio: Aaaaaah!

Azusa: Nooooo!!

Mugi: Girls!

Yui: H-Heyyyyy!!

They fell together on the floor of the basement and when they woke up...

Tae (Saaya): Owie, is everyone okay?

Rimi (Arisa): No we're not okay. Don't go grabbing people's sleeves.

Arisa (Kasumi): Sorry.

She said as she scratched her head.

Tae (Saaya): At least no one got hurt.

Ritsu (Mio): It's getting late. We should get back.

Yui (Azusa): Y-Yeah.

Azusa (Yui): Ah! You're right!

Saaya (Rimi): See ya!

Azusa (Yui): Can't wait to go home and eat some dinner!

Tae (Saaya): Gotta go home and do my homework.

Poppin'Party and Hokago Tea Time didn't realize something. They... switched bodies with each other.

Cut to the scene where Arisa (Kasumi) was going back to her "home" and once she got there, she greeted her sister.

Asuka: Hey, sis.

Arisa (Kasumi): I'm home, Acchan!

Asuka freaked out seeing Arisa greeting her instead of her big sister, Kasumi.

Asuka: Ichigaya-san?! Where's my sister?!

Arisa (Kasumi) then brushed her cheeks together with Asuka, but then Asuka went to run away from Arisa (Kasumi).

Asuka: Mom!

Meanwhile with Yui (Azusa)...

Ui: Azusa-chan? Why are you here?

Azusa (Yui): W-What are you talking about, Ui? It's me, your big sister.

Ui: Big... sister? You want us to roleplay or something?

Azusa (Yui): Ui-chan, what's for dinner?

Ui: Why are you asking this? Where's Onee-chan? Isn't she supposed to be with you guys?

Azusa (Yui) then looked at the mirror as she realizes that... they switched bodies.

Azusa (Yui): Eeeeeeeeehhhh?!?!

Back to Kasumi's House...

Arisa (Kasumi): Acchan's acting weird...

Arisa (Kasumi) was on the couch at the living room as her phone rings and she picked up her phone. The person who were calling her was Rimi (Arisa).

Arisa (Kasumi): Hmm? It's Rimi-rin. Hello!

She answered the call and Rimi's tsundere-ish voice can be heard.

Rimi (Arisa): Hello, who are you?! Ah, no, not in a weird way...

Arisa (Kasumi): Hmm? This is Kasumi.

Rimi (Arisa): This is awful... Just go look in a mirror.

Arisa (Kasumi): A mirror?

She then went to the bathroom to look at the mirror. Kasumi then realized that she's Arisa.

(Author's Note: Ah yes. Mirrored subtitles. I've never thought that this would appear.)

Arisa (Kasumi): Huh? Arisa's here! Why?

Rimi (Arisa): I don't know how, but it seems like we all switched bodies!

Arisa (Kasumi): What? We all...

Poppin'Party & Hokago Tea Time: Switched bodies?

Said everyone who were involved as they're having a phone call together.

Ritsu (Mugi): So that explains it.

Yui (Azusa): I'm... inside of Yui-senpai's body...

Mugi (Mio): Eeeeeh? This is really cool! I get to cosplay with Mio-chan's maid costume!

Mio (Mugi): This isn't funny! Give back my body!

Azusa (Yui): No wonder Ui was scared of me.

Rimi (Arisa): I tried calling everyone else, but it seems we went home all switched up, and now everything's a mess!

Arisa (Kasumi): Wow, well that... sounds pretty fun!

Rimi (Arisa): You dummy! It's not fun at all! Anyway, let's meet up at basement!

Timeskip...

Arisa's Basement...

Once again, the band members of Poppin'Party and Hokago Tea Time gathered up to find out what was the reason of why are they switching bodies.

Tae (Rimi): Why did we switch bodies?

Saaya (Tae): Maybe it was when we hit our heads...

Mugi (Mio): That explains it.

Kasumi (Tae): What are we supposed to do?

Arisa (Kasumi): I got it! From today, I'll live my life as Arisa!

Azusa (Yui): And I'll continue living my life as Azunyan!

Arisa (Kasumi) & Azusa (Yui): Yaaay!

Arisa (Kasumi): Kasumi, honestly...

Azusa (Yui): Yui-senpai, no tea time until we finished studying.

As Rimi (Arisa) saw Arisa (Kasumi) who were roleplaying as the real Arisa, she screamed and get really irritated by this.

Rimi (Arisa): You gotta be kidding! I hate this! Give it back! Give my body back!

Said Rimi (Arisa) as she were headbutting Arisa (Kasumi)'s head.

Tae (Saaya): Cut it out, you two.

Mugi (Mio): I don't want my family to stare at me like a creep! Give back my body, please! I'd rather cosplay as a maid than being a weirdo!

Without the girls realizing, they're at the stairs of the basement again.

Saaya (Rimi): Stop! That's my body!

Said Saaya (Rimi) as she slipped down the stairs causing the other girls to fall along with her creating an avalanche. Loud crash can be heard from the basement.

Once again, the girls went laying down on the floor of the basement. Then, all of them went awake from the fall.

Kasumi: Owie, is everyone okay?

Arisa: No, we're not okay! Huh?

Saaya: We're back to normal?

Mio: M-My body... I got my body back! I'm so glad!!

Yui: Eeeeeh? But... I want to live as Azusa.

Azusa: Not happening, Yui-senpai.

Rimi: Yay!

Arisa: Thank goodness!

After all of the chaos going on, everyone else went back home leaving only Arisa alone at Ryuseidou. She went back to the basement and feels glad to get her body back.

Arisa: Yeesh, I thought we were done for.

As she was about to relax, her phone received a notification. As she check it out... a lot of things that Arisa (Kasumi) did popped up on her phone and there's even pictures were taken.

There's Arisa (Kasumi) with Ako using their twin tails to make a mustache, Arisa (Kasumi) went to Hagumi's croquette shop as she ate a lot causing her to gain weight, Arisa (Kasumi) went to Hanasakigawa High School as Kokoro and Kanon were seeing her playing around unlike her normal self and a message from Asuka. However, what shocked her the most is that Arisa (Kasumi) went to hug you as she rubbed her cheek together with you causing some outrage from girls of each band.

Yukina: What do you think you're doing with (Y/N)-san, Ichigaya-san?

Chisato: (Y/N) belongs to me, Arisa!

Aya: I trusted you, and everyone else do too. Then, why in the bloody heck... would you betray us?

Arisa: Kasumi!

The camera points to the night sky from outside of Arisa's basement as her voice screaming can be heard.

(The end...)

(Ending song...)

(Post-credit scene...)

Right now, you were just going back home since you just finished your work shift for the day. Then, you saw Arisa sitting on a bench as you went to greet her.

(Y/N): Hey there, Arisa.

Arisa: Oh, it's you... (Y/N)...

(Y/N): Hmm? What's wrong?

After a moment of her not talking, she finally went to say what she was about to say.

Arisa: I-I wanted to apologise about what happened.

(Y/N): About what?

Arisa: Don't you know? About me hugging you and a picture of us together went to spread online. As a result, I got death threats from other girls.

(Y/N): Oh, that. It's fine though.

Arisa: Actually, it was Kasumi. We switched bodies at my basement and she went to have fun using my body.

(Y/N): Haha, it's like when someone else were using your email address and mess around with it. That's what happened to "you" when Kasumi was using it.

Arisa: Could you please not rub a salt to my wounds?!

(Y/N): Okay! Okay! Sorry.

Arisa: No. I-I'm the one who were supposed to apologise.

(Y/N): Arisa... I accept your apologies.

You then smiled at her and you went to pat her head as she blushed.

Arisa: W-Why are you petting me like I'm a pet?

(Y/N): Oh, sorry about that.

Arisa: I didn't tell you to stop.

You then continue to pat her head as you laughed a little seeing how cute she is.

Arisa: Everyone... I'm sorry.

(Author's Note: Feels seriously bad for Arisa. Oh well, at least you're here to comfort her. See you later.)
