Ruby, Weiss, Blake, Yang, Goten, and Trunks all watched Goku as he was teaching them a dance. 

Goku: After you match yoru Chi exactly, you ahve to take the exact same pose, first stand a ways apart, and then watch the angle of your arms. 

He put his arms parallel to each other. 

Goku: Fu- Flip your arms and get closer together. Take three steps. Sion! Make a fist! Watch the angle of the leg! HA! Then point your fingers together. Don't forget to straighten the outside leg and point your toes. 

Everyone:

Weiss: That ... was- 

Trunks: LAME! 

Goten: Yeah. 

Goku: And you have to be symmetrical to each other. 

Trunks: What does that mean? 

Goku: Piccolo, mind helping me out? 

Piccolo: WHAT?! YOU WANT ME TO DO IT?! 

Nail and Kami: Get it over with already! 

The two then did it together! 

Blake: What is Majin Buu up to at this point? 

Yang: I don't even want to imagine. 

Back with Buu...

Back with you guys... 

Baba appeared. 

Baba: Goku, it's almost time. We must return to the Afterlife. 

Goku: I see. I leave the rest up to you, Piccolo. 

Piccolo: Right. 

You then returned. 

(Y/N): Okay, I'm back. Sorry, I- 

Goku: (Y/N), I know you'll handle everything. 

(Y/N): Heh, good luck. 

Videl: Wait! 

Videl appeared. 

(Y/N): What is it Videl? 

Videl: I still think Gohan is alive out there somewhere. 

(Y/N): What makes you say that? 

Videl: Just a feeling. 

Ruby: We can't detect his Chi. 

(Y/N): Maybe ... it's possible. Goku, do you think you can check? 

Goku: Yeah, I will. 

Goten ran to hug his father! 

Goten: DAD! DON'T GO DAD!!! 

Ruby: AWWW! 

Goku: You need to be strong Goten, look after your Mother, okay? 

Goten: O-Okay. 

Goku: Bye everyone! See you again when you die! 

Goku takes off with Baba! 

(Y/N): I hope he finds him. 

At the Checking Station... 

Goku found King Yemma. 

Goku: Hey King Yemma! 

King Yemma: Goku! You're back early! What's going on Earth? Look at all these souls! 

He had a long line of dead souls. 

Goku: Stuff happened. The entire population might even come down. By the way, right before this whole crowd, did Son Gohan come by? He's my son. 

King Yemma looked through his book. 

King Yemma: No, can't say that he has come. 

Goku: SO HE ISN'T DEAD! 

King Yemma: But there was someone else! Dabura, the King of the Demon Realm! I never thought he'd die. He'd be too happy in hell, so I sent him up to Heaven! 

In Heaven... 

Dabura was seen frolicking through the flowers happily. 

Dabura: Ah! Such a wonderful day! Hello friends! 

He was mingling with everyone else in heaven! 

Back with Goku... 

Goku: Wait ... I think I can sense Gohan! Wait, he's not here or is he with King Kai .. hmm .. 

He then teleported to Shin's realm... 

Gohan: DAD! 

Gohan was wielding the Z Sword! 

Goku: What's going on here? Oh hey, it's Supreme Kai and the other guy! 

Kibito: ANOTHER ONE HERE?! 

Goku explained everything. 

Gohan: I see. 

Goku: Wow, that sword is cool. Do you think I can chill here until Gohan goes to fight Buu? 

Shin: Uh ... sure ... I guess. 

Back with Buu... 

https://youtu.be/R_8Xal6Jf-o

Play from 0:03-end... 

Back at Shin's Realm... 

You arrived. 

(Y/N): HEY! 

Goku: (Y/N)! How did you get here? 

(Y/N): Instant Transmission, duh! 

Goku: Oh yeah! Sometimes I forget you can use that too. 

Kibito: ANOTHER ONE HERE?! 

Shin: (Y/N), how did you- 

(Y/N): Shin, you're okay! HEY! KIBITO! YOU'RE ALIVE! 

Kibito: Y-Yes, I am. 

(Y/N): So, what's going on? 

Shin: Gohan is training with the Z-Sword to fight Majin Buu. 

(Y/N): You don't say. How about we put it to use? 

Shin: Right. 

Shin summoned a giant metallic block. 

(Y/N): Wow. 

Goku: This stuff is hard. 

Shin: that's klangite, the hardest metal in the universe. 

(Y/N): Really? Well, here we go! GOHAN! GO LONG! 

Gohan: ALRIGHT! 

You tossed it at Gohan and as he swung the Z-Sword, it broke! 

(Y/N): WHOA! 

Goku: Uh ... 

Shin and Kibito: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAGH! 

Gohan: Oops ... looks like it broke. 

Shin: NOOO! NO NO NO NO NO NO NO NO NO NO! TELL ME IT'S NOT TRUE KIBITO! 

Kibito: IT'S TRUE! THE Z-SWORD BROKE! 

Goku: Well, you did try it on the hardest metal. 

Shin: But ... it's a legendary sword. 

Kibito: HE who masters the sword should have limitless power. 

Gohan: I think it's overrated. But I did get a good workout. It was pretty heavy. 

(Y/N): HEY YEAH! It's like training at high gravity! 

Shin: Yes, if you gain so much strength, you'll be even greater once you turn Super Saiyan! That must be it! 

???: Well, I wouldn't count on that. 

Everyone: HUH?! 

An old man appeared. 

(Y/N): Who's the old guy? 

Old Kai: I'm the Supreme Kai from 15 generations ago. 

Shin: WHAT?! 

Kibito: YOU'RE A SUPREME KAI?! 

Old Kai: That's right. A long long long time ago, there was a terrible bad guy. Almost as powerful as Bu! And he sealed me away in the Z-Sword! He was scared of me,  you see. But now I'm free! 

(Y/N): Uh ... he doesn't look that strong. 

Goku: Maybe we should test him out! 

(Y/N): NO GOKU DON'T! 

Goku blasted Old Kai in the face! 

Old Kai: GYAAAAAAAAAAAAAAAAAAAAA! 

He went tumbling back! 

Shin: GREAT ANCESTOR! 

Old Kai: AAAAAAAAAAAAARGH! YOU IDIOT! WHAT WAS THAT FOR DODO BRAIN! 

(Y/N): That was just ... child's play. 

Gohan: Even my little brother could handle that. 

Old Kai: Hmph! He wasn't afraid of my strength! He was afraid of my special power. 

(Y/N): And that is? 

Old Kai: Well, I'm not going to tell you! 

He stuck his tongue out. 

Goku: Not even for a girlie magazine? 

Shin: GOKU, WHAT ARE YOU- 

Old Kai: HEH! I don't need magazines! I have my godly vision, so I can see real women! Even when they're changing clothes! 

Shin fell back in shock! 

(Y/N): How did you know he was a pervert? 

Goku: He reminds me of Master Roshi! 

(Y/N): Oh yeah, he does kind of resemble Master a bit. 

Old Kai: My, even I can see some beautiful girl with cat ears. Yes, she's got some big boobies that she- 

You ran over and hit him! 

(Y/N): YOU STOP THAT RIGHT NOW! 

Goku: Sheesh, hey Gohan, why don't you try introducing him to your girlfri- 

Gohan: NO DAD! HELL NO I'M NOT DOING THAT! 

Goku: Okay, then how about another girl like- 

(Y/N): Goku. 

Goku: Y-Yeah. 

(Y/N): You're not talking about Bulma are you? 

Goku: Uh ... 

(Y/N): YOU CONNIVING LITTLE- HOW COULD YOU MAN! THAT'S NOT COOL TO USE ANOTHER GUY'S GIRL LIKE THAT! IF YOU WANT TO ENTICE THIS OLD GEEZER WITH SEXY THINGS LIKE THAT! THEN TAKE IT UP WITH YOUR OWN WIFE! 

Goku: But Chichi's not nearly as pretty as Bulma is! 

(Y/N): You're just saying that because if you went to Chichi, she would destroy you. I know personally how scary she can be when provoked! Wait, Old Kai! I have an idea! 

Old Kai: You do? 

(Y/N): Yeah. I do in fact. Hahahahaha. 

You smirked and pictured turning Kazuma into a girl and leaving him with Old Kai. 

Meanwhile... 

Kazuma: I sense ... something bad is going to happen. 

Back with you... 

Old Kai: Okay! You got a deal! So, my powers allow me to draw out the hidden abilities far beyond the normal limits of even the most skilled fithers! 

Shin and Kibito were amazed. 

Goku: But we see that every day. 

Old Kai: I can go beyond the normal limits! Nobody else can do that! Say, you, the one who drew the sword. If you can swing it around already, you'll really be the strongest under the heavens by the time I'm done with you! 

Gohan: OKay. 

Old Kai: HERE I GO! LET'S DEFEAT MAJIN BUU! 

He proceeded to do a weird dance. 

(Y/N): What the hell are you doing? 

Old Kai: QUIET! THIS IS AN ESSENTIAL RITUAL! 

Goku: How long is it going to take? 

Old Kai: Five Hours and 20 for the poer-up! 

Gohan: WHAT?! 

Back on the Lookout... 

Ruby and Weiss: Fu- 

Blake and Yang: Sion- 

Goten and Trunks: HA! 

They were practicing the dance! 

Piccolo: Good, almost perfect! 

Ruby: Thanks Piccolo! 

Piccolo: And now it's time to match your Chi Levels. 

As time passed on... 

The three pairs got ready to show everyone their transformation! 

And- 

Three fat people appeared! 

Yamcha: Uh ... 

Eveyrone was in shock. 

Piccolo: WHAT?! 

Bulma: This better be reversible! 

Chichi: Not even a mother can love that. 

Krillin: Uh ... Goku said that these warriors could beat Buu? 

Yamcha: Wait, maybe an eye for an eye! A fatso for a fatso! 

But they tired out quickly. 

Roshi: Tsk tsk. You girls, I expected better from you! 

Ruby and Weiss Fusion: MASTER! COME ON! 

Roshi: Hey, if you want, I can find a use out of th- 

Blake and Yang Fusion: NO! 

Roshi: Awww ... ruin your master's fun. 

Piccolo: Your finger was pointed when you Spoke Sion, your hands must be in a fist at that point. 

They then turned back. 

Blake: Well, that was ... unsettling. 

Yang: Man, it felt like after I ate too much fried chicken. 

Ruby: You do love your fried chicken. 

Yang: Hey, can you blame a girl? I remember this one time when I went on an eating contest against Leone and- 

Piccolo: AGAIN! 

Yang: Who died and made you God, Piccolo? Sheesh. 

The three pairs tried it again! 

And- 

Three old people came out. 

Ruby and Weiss Fusion: Huh? What day was it again? 

Blake and Yang Fusion: Back in my day, we used to look much better than Master. 

Roshi: HEY! I'M STILL YOUR MASTER, YOU KNOW! AGE HAS NO DIFFERENCE! 

Krillin: Sheesh, this is getting tiresome. 

Ruby and Weiss Fusion: WATCH IT KRILLIN, OR YOU'RE GETTING A SHAVE! 

Piccolo: Your fingers were out of alignment when you spoke HA! Go again. 

Finally... 

This time they got it right! 

Gotenks

Reiss 

Blang 

Everyone was in shock! 

Reiss: WE DID IT! WE DID IT! Of course, we did it, Ruby. We are always in sync. 

Blang: This is badass! I'll say. So, what do we call ourselves? 

Reiss: REISS!

Blang: Okay, then we call ourselves Blang! 

Gotenks: And we're Gotenks! 

Roshi: AMAZING! THEY DID IT! 

Piccolo: Okay, as for you two, we'll try it again as Super Saiyans. 

Gotenks: WHAT?! This is enough to beat Buu! 

Reiss: Goten! Trunks! This is no game! He's too powerful for you at th- 

He left already. 

And then- 

Gotenks: AAAAAAAAAAAAAAAAAAAAAAAGH! 

He was sent flying back. 

Gotenks: He beat us up good. 

Blang: WHAT DID YOU THINK WAS GOING TO HAPPEN IDIOTS?! THE GUY CAN LITERALLY SHRUG OFF DAMAGE LIKE IF IT WAS NOTHING! 

Meanwhile... 

Hercule snuck over to Buu's house. 

Hercule: Wow, it looks like he's not at home. HAHAHA! COME OUT BUU! YOU'RE MATCH IS MADE! I- 

He then heard a step. 

Hercule; AAAAAGH! I'M SORRY BUU! PLEASE I DIDN'T MEAN TO DISRESPECT YOU! I- 

It was just a lizard. 

Hercule: Oh, it's just a lizard! Ha! As if Buu can actually scare- 

Buu: Hello! 

Hercule: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAGH! 

Buu: What kind of candy do you want to turn into? Cookie? Lollipop? 

Hercule: NO WAIT! I got you a present! 

He brought out a box of chocolates. 

Buu: OOH! CHOCOLATE! THAT'S BUU'S FAVORITE! 

He began to eat them. 

Buu: MMM! Even better than human chocolate! You're nice! Buu make you friend! 

Hercule: F-Friend? 

Buu hugged him! 

Hercule: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAARGH!
