The four walked back to camp in silence, senku glared at taiju the whole time; while tsukasa walked closely behind (y/n). It sent shivers down her spine, the sound of his feet provoked a kind of fear she's never felt with him. Usually (y/n) feels safer with him. However after seeing him kill a man.... 

When the four got back to camp, taiju clothed yuzuriha. While (y/n) just stood awkwardly next to Tsukasa. 

oh god... my fucking best friend killed someone. oh god.

(y/n) was sweating bullets. She was standing next to a murderer. But she had to keep cool, make it look like she didn't want to throw up whenever she looked at her friend. So (y/n)  put a big smile on her face.

And held his hand.

before he could say anything to her, taiju talked.

"There we go yuzuriha! At last, this time, I'm really going to set you free!"

Tears of happiness were falling out of his eyes, but that was ruined by senku rudely interrupting his best friend.

"What the heck, there's not even enough here to revive one person. (y/n) can you get some more revival fluid."

"su-"

"no, it's dangerous if you go alone (y/n)."

Tsukasa spoke, tightening his clutch in her hand. Not breaking her smile she just sighed and looked at her friend.

"WHAT?! GAH! SORRY I WAS SO EXCITED AND IN SUCH A RUSH... I'LL GO GET MORE RIGHT NOW!!"

"I don't want to sit around all day and play I spy with tsukasa and (y/n) so hurry up."

Taiju was about to run off, but tsukasa, still holding (y/n)'s (s/t) hand grabbed taiju and stopped him.

"well then, it'd be faster if i went. so how about you tell me where the miracle water is?"

Senku told the brunette the location, making Tsukasa quickly let go of (y/n)'s hand. He ran off, only a few steps, before he ran back to (y/n) .

"I promise i'll be back. We can talk about what happened later, and if anything hurts you, don't worry i'll deal with it."

Trying to get me to trust you more and more Tsukasa... I know what you promised me, no need to remind me unless you're trying to play trick with me. Make me forget you murdered someone, I can't only remember the good.

"Of course! Also no need to be rough with taiju, please be a little gentler next time."

(y/n) said with a smile. Thankfully Tsukasa believed her smiles and polite gestures she's been doing. He then ran off. Leaving the three behind. Around 2 minutes after he left senku spok.

"Is Tsukasa gone?"

Senku asked, yawning.

"yeah he left right away! At incredible speed..."

senku rushed to the miracle water.

"GOOD. THEN LET'S MAKE SOME REVIVAL FORMULA AND REVIVE YUZURIHA AS FAST AS WE CAN. WHILE TSUKASA IS GONE, (Y/N) GET THE WINE RIGHT AWAY."

The scientist yelled, (y/n) and senku were rushing against time.

"What..? what's going on here Senku, (y/n)?! Just a second ago, you said we didn't have enough revival formula..."

Taiju asked in utter confusion. running into the lab with (y/n) and senku.

"As if i'd left a jar there that wasn't the right size? Seriously. Also good acting before (y/n) it may have gotten him to soften up more." 

"you've got a point! but then why did you let sukasa go? And acting? I thought you were best friends (y/n)?"

Taiju looked back and forth between the two.

"Taji-kun... you're so out of the loop!"

"Look taiju, it's a double edged bait. Even if it meant him finding out where the cavewas, I wanted him away from us before we revived yuzuriha."

"why?! Why would you get rid of him? Especially you (y/n)! He's a good guy, isn't he?"

The brunette desperately said, looking for some kind of answer. He looked over to (y/n) his eyes pleading her for something, anything.

"taiju he... oh god..."

(y/n) tried to explain, but tears were forming her eyes. So senku rubbed her back, continuing on for her.

"We both don't have a single millimeter of inteest in his grandiose dreams of the strongest, ultimate world. kukuku... what excites me is this real life game of civilization."

senku said. Taiju got a serious look on his face.

(y/n) is crying... it must be serious. But yuzuriha would love to see this!

He thought, looking at (y/n) and senku hugging. It was a rare sight to see senku giving (y/n) any kind of comfort. Usually he just watches from afar. Never really doing anything.

"I got it! I don't need any explanation. Senku, (y/n) . If you say it then it must be so."

 "yeah... taji-kun he..."

"shishiou tsukasa... he may be a good guy, but he's a murderer."

.

.

The three went out. Reviving Yuzuriha. Taiju said his love confession.

"The reason i was able to survive all that time.... was because of you yuzuriha. And yet... i'm sorry, I wasn't able to protect you...

 I'VE ALWAYS LOVED YOU! FOR HUNDREDS, AND THOUSANDS OF YEAR!!!"

Yuzuriha was revived. It was a beautiful scene to witness from the perspective of (y/n), her two best friends getting together. So sweet. Senku glanced at (y/n) from here and there.

That big oaf... he doesn't know what he's getting himself into! Love is unpredictable and it is irrational. 

"YUZURIHA!!! AAAAAAHHHHHH!! ARE YOU THERE, YUZURIHA?"

"taiju...? Is that you?"

"YES... yes.... I'M SORRY!! SORRY YOU HAD TO WAIT THESE 3,700 YEARS. I'M SO SORRY!"

"It felt like i just woke up... but i have a feeling that i'm meant to be here. Because you saved me.. didn't you taiju? you did."

The tears of joy taiju was shedding fell onto the girl's face. Which made him realise he should probably let her get up.

"It wasn't me. It's all thanks to (y/n) and Senku. They have spent an entire year developing the revival formula."

He said, whipping tears from his eyes.

"It was no big deal! I'm so glad you're awake again yuyu-chan!"

(y/n) said, helping the girl up. 

"kukuku sorry to break up your touching reunion talk, but before Tsukasa gets back we need to decide something immediately. There are only two paths to choose from, we've got to pick which to take!!"

oh god this isn't going good, i swear to fucking god if he metions sacraficing himself i'll lose it.

(y/n) thought, crossing her arms.

"Plan A! Taiju and Yuzuriha, you two get the hell away from here right now, go somewhere far away and live on."

"Bitch you're sacrificing the both of us this time!"

(y/n) spoke, in an obvious joking tone.

"well of course! What if i need my assistant at my aid while i die."

"Whatever... but i think i know what plan B is... It's to fight and stop Tsukasa's murdering? With the power of science!"

"Ding ding! 10 billion points for you (y/n), so what do you two say-"

"I'VE GOT MY ANSWER! OF COURSE WE FIGHT!! DON'T GO MISJUDGING ME AND YUZURIHA, SENKU (Y/N)!"

"SORRY! BUT IT'S JUST BETTER IF WE DO GIVE THE OPTION SO YOU TWO DON'T DIE POINTLESS DEATHS! SENKU AND I JUST WANT YOU TWO TO BE SAFE!!"

"YEP YEP I HAVE NO IDEA WHAT'S GOING ON, BUT I'LL HELP HOWEVER I CAN!"

"Alright, I get you two are dedicated and willing. So just listen to my explanation... you guys seriously look like a married couple."

The four made so much noise, taiju and yuzuriha were yelling at the doctor and scientist. 

"IF TSUKASA IS REALLY DESTROYING STATUES, IF HE'S REALLY KILLING PEOPLE, THEN NO MATTER WHAT IT TAKES-"

"I'm not killing for the sake of just killing. It's simply the solution I've arrived at."

A voice said from behind senku and (y/n).

fuck Tsu-kun is back... why the fuck did he have to do this, of all things! 

"I'm just thinning out the population. To create a new world."

Tsukasa spoke. As (y/n) turned around Tsukasa dropped a few pieces of statue out of his hand. (y/n) was terrified. 

"of all people (y/n).... I thought you'd think a bit more highly of me. Oh well it's not like you'll have a choice or not to join my empire."

his what...?
