Everyone was celebrating with joy at Chrome's escape! 

Suika: SCIENCE IS AMAZING! IT CAN EVEN HELP YOU BREAK OUT OF JAIL! 

Weiss: That's what I've been wondering. How did you escape? 

Chrome: With a little help from Senku's pals. One of them slipped me a battery, and I used it to whip up a chemical. 

Blake: Taiju thought that far ahead? 

Senku: HAHAHAHAHAHAHAHAHA! No way, a clever scheme from him is ten billion percent unlikely. 

(Y/N): Of course, Yuzuriha is the smarter one. 

Senku: True, but she has her hands full with her own top secret mission. And she's not the type to get distracted and neglect something like that. 

Ruby: But if it wasn't Taiju and it wasn't Yuzuriha, then who was it? Maybe ... Nikki? I mean she's on our side now ... or was it ... UGH! I don't know! 

(Y/N): Well, it looks like more of Tsukasa's men are joining our side. Which we really can't complain about. 

Kaseki: Looks like my precious Steam Gorilla won't go to waste! 

Chrome: The wh- AAAAAAAAAAAAAAAAAAAAAAAAAGH! 

Chrome was in shock at the tank! 

Yang: Check out this bad boy! Yeah, we made a tank out of paper shields! 

Senku: And it'll be mighty handy when it comes time to claim victory on the final battlefield! 

Kohaku: Final battlefield? What are you talking about, Senku? 

Senku: It all ends when we fight over the Miracle Cave! 

(Y/N): Ah, of course, if Tsukasa can't have the nitric acid, then he can't get any more of the Petrification Cure and Gunpowder. Whoever has the cave is the winner. 

Weiss: In that case, Tsukasa is going to throw all of his men at us. 

Suika: But don't they have like a hundred people?! 

Magma: So what?! We can pull this off! I mean we have our brainiacs over there to think of something! 

(Y/N): Even better is that, Gen's plan is going to work out as we speak. 

At the Empire of Strength... 

Gen was playing the song to make it look like he was Lillian! 

Guy: Hey, is that- 

Girl: IT'S LILLIAN WEINBERG! THE REAL DEAL! 

Lillian: Hey, Japan! How are you doing?! 

Nikki: Good, it looks like the drilling paid off. He's even perfected the Southern drawl! 

Lillian: Civilization is up and running in the United States! And we're ready to save y'all! 

Empire of Strength: WHOOOOO! 

Taiju: YEAH! 

Yuzuriha was a bit freaked out at Taiju getting too into it. 

Nikki: Just make sure to keep quiet. Remember that Tsukasa rejects the authority of the old world. You really think he would agree to play nice with the American Military? 

Guy: SO WHAT?! LET THAT JERK DO WHAT HE WANTS! 

Girl: YEAH! THE US IS GETTING REVIVED! HE DOESN'T STAND A CHANCE AGAINST ARMED SOLDIERS!!! 

Lillian: You're darn right! Keep in mind, it'll be a little while before the US Army can get here. We're hoping to stop Tsukasa from destroying more statues, so until then, y'all go along with Senku's strategy, okay? 

Taiju: HA! This Lillian persuasion plan is winning us more allies by the day! 

Nikki: Yes, it's working so well it's almost scary. It's human nature, when people get comfortable, that's more dangerous than anything. 

???: Enjoying yourselves? 

Ukyo appeared. 

Ukyo: Mind if I listen into this call? 

Nikki: CRAP! Ukyo! 

(Y/N): Gen! Keep going with it! 

Lillian: This is Lillian Weinberg, y'hear? Who'm I talking to? 

Ukyo: You almost had me fooled, however, after belting out a song like that, your voice should have a nearly imperceptible tremor to it. You didn't manage to mimic that, Gen. 

Sci-Twi: Wow, he's good. 

Gen: AGH! I knew this was a lost ause-cay. Wait ... why on earth did Ukyo reply to us like that? 

(Y/N): Hmm ... that's true. He also didn't alert anyone when he attacked you guys. HEY! Ukyo, this is- 

Ukyo: (Y/N) right? I know. 

(Y/N): You're the one who gave Chrome the battery! You helped him escape! 

Ukyo: That's right. Because without my intervention, something bad would have happened. Look, I wouldn't call myself an ally. 

(Y/N): True, if you were, you wouldn't have thrown Chrome in a cell. 

Ukyo: I'm still investigating you to see what's going on. And I saw everything that's going on. 

Ukyo had been spying on Yuzuriha, who was collecting all the stone fragments of the people that Tsuksa had shattered and stitching them back together! 

Ukyo: Even wth the world as it is, you people are attempting to save all of humanity with the power of science! 

Senku: So, are you going to tattle on us to Tsukasa? 

Ukyo: No, I believe that helping you guys might do the right thing. But on one condition. 

(Y/N): Condition? 

Gen: (Y/N), let me talk. Negotiating deals are the forte of a mentalist. 

(Y/N): Go ahead, Gen. 

You let Gen do the talking, but- 

Senku: Dancing aroud this is a waste of time, get to the point. 

(Y/N): Well there goes that. 

Gen: AAAAAAAAAAAAAAAAAARGH! 

Ukyo: No one dies, including Tsukasa and Hyoga. 

(Y/N): What's this? Are you a pacifistic idealist or- 

Ukyo: No, what I am is a coward. More than anything, I want to avoid a massacre between our camps. I was willing to overlook Tsukasa's nasty statue-smashing habit. He said that they're just things, not people. And that not reviving them isn't actually murder. But I can't bear watching people die. In this world, what can we hold on to, if not that? Promise me that no lives will be sacrificed, and I will join your side. But if you kill a single person- 

(Y/N): Okay, you've got yourself a deal. Besides, we weren't going to kill anyone. 

Gen: That's still a tough promise to keep. 

Ukyo: Thank you. And another thing, when Hyoga returned after attacking your village, he reported back that his underlings were killed by your schemes. I can tell now that you weren't to blame! It was him! Though they're both strong, both of them are different people! I can't sit on the sidelines any longer! 

Ruby: Hyoga actually- Oh no. Maybe he's- 

(Y/N): Tsukasa is in trouble. Hyoga's going to betray him! 

Meanwhile ... 

Hyoga was searching near the grave. 

Hyoga: Hm ... these footprings here are too neat. It's as if someone swept the whole are clean and laid a fresh set to imply a single grave visitor. Was there some sort of gathering here? 

Tsukasa appeared. 

Hyoga: I heard that some of my men had come to the grave, did you too, my Lord? 

Tsukasa: No, I'm here to pay my respects to our dearly departed Yo. 

Yo had fled and faked his death in order not to get in trouble for letting Chrome get away. 

Tsukasa: A pity, he's returned to the Circle of Life. Gozen, Yuki, Ren, Akashi, Kyoichiro, Morito, too. Let us pay our respects to them. 

Hyoga: Who are they? 

Tsukasa: The ones who were taken out by (Y/N) and the villagers. 

Hyoga: Right. Pathetic. 

Meanwhile... 

Sci-Twi: IT'S FINALLY FINISHED! 

Senku: HA! Our awesome paper tank is now fully functional! GET EXCITED! 

Sci-Twi: We finally did it after so long! 

Ruby: So, how does it work? 

Sci-Twi: We use this leather rupture disk! We sap the water inside to make it bubble. The resulting hydrogen and oxygen build up and inflate the rupture disk, and then KABOOM! 

Chrome: Oh yeah, that makes sense. That setup is simple enough for me to understand! EXCEPT IT'S A ONE AND DONE SINCE THE THING RIPS APART! 

Senku: That's fine. Those modern timers are ten billion percent sure to lose the will to fight after just one shot from the tank! 

Yang: Of course! WE GOT A FUCKING TANK BABY! 

Kohaku: If we hope to suppress them without any loss of life, it'll all be decided just after that initial shock! 

(Y/N): We've also got- TAIJU! 

Taiju appeared. 

Yang: Welcome back, Dummy! 

Weiss: It's good to see you again, you big idiot. 

Soon... 

(Y/N): LET'S GO EVERYONE! 

The tank appeared and fired right at Tsukasa's men by the Miracle Cave! 

Yang: BLITZKRIEG! BLITZKRIEG!! 

Senku: We can only afford 20 seconds of this! 

Yang: HOLD ONTO YOUR BUTTS! LET'S RAM THIS SON OF A BITCH!! 

Muscle Man: OH NO BROS!!! 

Guy: THEY GOT A TANK!!! 

Magma: HAHAHAHAHA! YEAH WE GOT A TANK! WHAT NOW?! 

Ruby: CHARGE!! 

Ruby was leading all the warriors right to Tsukasa's men! 

Taiju: COME ON! 

Taiju was taking so many hits and kept charging in! 

Guy: HOW STRONG IS HE?! 

Muscle Man 2: I THOUGHT I GOT HIS HEAD, BRO!!! 

Taiju: I'M READY TO TAKE ALL THE PAIN LEADING THE CHARGE! HURTING PEOPLE IS JUST PLAIN WRONG!! 

Ruby: LET'S GO!! 

Ruby, Weiss, Blake, and Kohaku were tearing through the warriors! 

Kinro and Ginro were doing tag team attacks, and even Kokuyo was knocking guys out, and then- 

Yang: AGH! Shoot, it was fun while it lasted! 

Guy: HA! WE GOT THEM RIGHT WHERE WE WANT THEM! 

Muscle Man 3: You know who else has them where we want them? MY MOM! 

Guy 4: Dude, can you stop it with that? 

(Y/N): MAGMA! 

Magma brought out a giant pot lid! 

(Y/N): EAT THIS! 

You punched it, releasing a giant sonic blast that blew down all of the bad guys! 

Minami saw the whole thing. 

Minami: Uh oh, this isn't good. We're getting creamed. But I- 

She saw you. 

Minami: 

https://youtu.be/Bh5qlCwpOns

Play from 0:18-0:45... 

At that moment Ukyo shot an arrow near her! 

Minami: AGH! UKYO! 

Nikki: Nice try! 

Nikki appeared behind her and tickled her! 

Minami: HAHAHAHAHAHAHAHAHAHAHA! STOP! THAT TICKLES!!! 

(Y/N): TAIJU! 

You got Taiju and then Yang joined in! 

(Y/N): BOTH OF YOU! SCREAM! 

Sci-Twi and Senku made the tin lid like a microphone and- 

Yang and Taiju: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAGH! 

Their screams blew all of the bad guys away! 

In 20 seconds, the Miracle Cave was now under control of the Kingdom of Science! 

(Y/N): NITRIC ACID IS NOW OURS! 

Sci-Twi: We can make both Petrification Cure and Gunpowder as much as we want! You ready Senku?! 

Senku: Yeah, let's get to work! 

Chrome: Alright! Let's whip some up before Tsukasa and the rest of his guys show up! 

Sci-Twi and Senku got out some sulfur and charcoal! 

Sci-Twi: This will help us out big ti- 

Ukyo: EVERYONE! RUN! 

(Y/N): Ukyo, what's going on? 

Blake: Shit, he's right! LOOK OUT! 

Sci-Twi and Senku were both hit as the chemical compound was destroyed! 

(Y/N): NO! OUR INGREDIENTS!!! 

Several muscle-bound men appeared! 

Ruby: Oh no! It's them! 

Both Tsukasa and Hyoga appeared! 

(Y/N): Tsukasa, long time no see. 

Tsuksa: Hello, old friend, it's been too long. It pains me to know that this time, I'll have to kill you. 

(Y/N): Ouch, hat really stings. 

Guy: HEY, Lillian is in the tank! We got to keep her safe, before- 

Hyoga: LIARS! ALL OF YOU! Gen, show yourself! 

Gen: Uh ... h-hi. 

Gen popped up all scared. 

Guy: IT WAS GEN?! 

Girl: You were impersonating her? How could you?! 

Tsukasa: Looks like the outcome has been decided. Senku, just give yourself up. 

Hyoga: You've lost, give it up. 

(Y/N): Oh please, it's different. 

Hyoga: What? 

Yang: You only got to Senku because we weren't there, and you caught Yuzuriha. Now look at us! WE GOT AN ARMY! 

Kinro: We'll fight to the end! 

Ginro: No backdown for us! 

Chrome: And there's another science guy here! 

Kokuyo: You wish to harm our new friends? That we can't allow! 

Magma: Science is better than whatever you have to offer anyway. 

Kohaku: Nice to se you again, Tsukasa! REMEMBER ME?! 

Tsukasa: Of course. 

(Y/N): SCI-TWI, CHROME, SENKU! FOLLOW ME! 

You three ran into the cave! 

(Y/N): GO FOR IT GUYS!! 

Ruby: CHARGE!!!! 

Ruby lead all the fighters to take on Tsukasa, Hyoga, and their men! 

Tsukasa: How foolish to throw your lives away. 

Both Tsukasa and Hyoga charged in! 

As the muscle men were getting beaten down, well- 

Yang: HEY! TSUKASA! HAVE SOME OF- 

Yang tried to hit Tsukasa, but Hyoga tripped her with his spear! 

Yang: AGH! 

Tsukasa: You have strength, Yang, but you're not that smart! 

Tsukasa floored Yang to the ground! 

Ruby: SIS! YOU JERKS! EAT THIS! 

Ruby clashed with Hyoga! 

Weiss: COME ON! 

Weiss used the tin shield, with Nikki, and Magma backing her! 

Weiss: THIS IS A STONE AGE BATTERING RAM! EAT IT!

The three charged at Tsukasa, but he threw his spear, knocking them into a wall! 

Taiju: YOU GUYS!!! 

Inside the cave, you were cheering your men on as Senku was getitng to work. 

Gen: ARE YOU KIDDING ME?! WE'RREUSING BAT POOP?! 

(Y/N): Don't worry, Gen, it's fine! We just need something like ... crap! If only we had sulfuric acid! 

Senku: This would be a bad time not to have any! Especially because- 

Ruby: GO! 

Team RWBY, Kinro, Ginro, Magma, and Kohaku all tried to hit Tsukasa, but he took them all down easily! 

(Y/N): TSUKASA'S MAKING MINCEMEAT OUT OF EVERYONE!! What do we do?! 

Chrome: Hey, need a hand? 

Sci-Twi: Chrome, what do- 

Chrome held some sulfuric acid! 

Sci-Twi: NICE JOB CHROME!! TIME FOR SOME SCIENCE!!! 

Soon.. 

Senku: YES! We have nitroglycerin! 

Gen: Wait ... I've heard of that before ... and- AAAAAAAAAAAAAAAAAAAAGH! THIS IS UTS-NAY!! 

Sci-Twi: Calm down, Gen, it's going to be fine. No one is going to die. But this bomb will take them down! Now how do we get it out there? 

Gen: Hmm ... 

Gen constructed a paper airplane. 

Gen: This design won the Guinnes World Record for longest flying paper airplane! 

(Y/N): HA! Our brainiacs have come through again! Now- 

You threw it out! 

(Y/N): OH TSUKASA! HAVE SOME OF THIS! 

It hit a nearby tree. 

Tsukasa: A paper airplane? 

(Y/N): Wrong, it's dynamite!!! THIS IS THE POWER OF SCIENCE!!! UKYO! 

Ukyo: Got it! 

Ukyo fired a flaming arrow straight at the airplane and- 

KABOOM!! 

Gen: So destructive! 

Ruby: YES!!! 

All of Tsukasa's men surrendered! 

Chrome: HELL YEAH! 

Taiju: WE WIN!!! 

Tsukasa: Looks like there is no way to evade your weapon. But others surely could have died. (Y/N), you are not the type to sacrifice people like that. 

Senku: Guess we're at a stalemate. 

Tsukasa: By your own design, of course, you intended this. Which tells me that your goal was to make a deal, right? 

Senku: Yep. 

Sci-Twi: Gen, you mentioned that Tsukasa, he was shooting a TV Special when you first met him. 

Gen: Yes, why? 

Senku: He talks about purging socity of the rich, powerful, and corrupt. He's giving it all for those ideals. 

(Y/N): But he's the same guy who fought in the ring, and was making dough. That doens't add up. 

Gen: Exactly! Why would he want so much money if he already makes it? 

(Y/N): Tsukasa, do you have someone important to you? 

Tsukasa: I ... yes. I have a little sister. 

(Y/N): I see. 

Tsukasa: her name was Mirai, and she was pronounced critically braindead. I fought to earn as much money as I could. An- 

(Y/N): I'll help you. 

Tsukasa: Wh-What?! 

(Y/N): You have to promise me to give up your goals, if you let us help you. Please, Tsukasa. Stop this meanless bloodshed. 

Tsukasa: How do I know I can- 

(Y/N): As a hero, I will not someone innocent down. Just give up, Tsukasa, please. 

Tsukasa: Everyone, stand down. 

Soon... 

You, Sci-Twi, Senku, Chrome, and Gen searched the beach near the Empire of Strength! 

Tsukasa: I believe her hospital was around here. 

Sci-Twi: We've got a lot of digging to do. 

Senku: Or we use dynamite! 

Sci-Twi: YOU MADE MORE?! 

Gen: What if the statues all break from that?! 

Senku: We got a way to put them back together after all! 

Sci-Twi: You know Yuzuriha is over there, right? 

Yuzuriha: That wasn't easy to do, you know. 

(Y/N): WELL, LET'S GET TO WORK! 

A lot of digging later... 

(Y/N): HEY! Is this her?! 

Tsukasa: That's ... her. 

He began to cry. 

Tsukasa: Mirai. 

You looked at Tsukasa, and- 

(Y/N): I know what it's like to have a little sister. Not just Suika, but also girls like Wendy. If Wendy was turned into stone, I would not rest until I found a way to get her back. Guess, we're not so different. Senku! Sci-Twi! 

Senku and Sci-Twi constructed the Petrification Cure, and- 

Mirai broke free! 

Mirai Shishio (Tsukasa's little sister! She is a sweet little girl who loves her big brother very much! Gets curious and excited about new things! Voiced by Emi Lo (The Voice of Mao Mao from Apothecary Diaries!)) 

Mirai: What? Where am I? 

Tsukasa: M-Mirai. 

Mirai: Big Brother? Ha, looks like you've grown up! How long was I asl- 

He hugged her! 

Tsukasa: 6,000 years. 

You cried hard. 

(Y/N): Tsukasa, take good care of her, okay?! YOU HEAR ME?!
