After so many months it's ready, but I do have announcement to make, the last chapter are gonna be either one or two, and somethings might not be including like certain flashbacks like on the space station, that's is if I have time. And I have a deadline to finish this, so please feel rest assured, I'm not completely finishing this book,  the final chapter is of when gen tells them about tsukasa, you'll just see the other chapters in the second one in season two, but if I managed to come back to this, I'll add them in when i can

Gen began walking back towards the bridge "I think it's best if I leave the village for now" he says, the only ones watching him were kinro and kaseki "I'm an outsider and I'm not competing, So I bet our kinro will through a fit if I didn't~" he smirked while Kinro and kaseki wheezed, However they weren't the only ones listening " I came here to have a little chat with you and yuna senku, but I'll be patient" he says " we can discuss your end of the deal after you've taken over the village"and with that began his leave

"Sure" senku replied still smirking

Meanwhile ruri watched with a face of relief, her friend was okay "Oh chrome..."

"Ruri" the person below below who was Ginro called out gaining her attention "Priestess I mean, your gonna have to marry the winner right?" He questioned, then turned his head towards her, hand blocking the view of his mouth from others " don't worry, it's down to us four, and senku and I are just gonna throw our matches, that leaves chrome and the goddess left, your in safe hands" he grinned

Ruri looked surprised " don't look so surprised, it's pretty obvious, I can tell you've been rooting for them" ginro stated, in the background her father didn't look too pleased, angry of anything, her eyes caught the two interacting with senku "Nice job figuring out the difference between convex and concave chrome senku praised, however yuna only watched confused cause he was nudging him in the back as chrome laughed

"No, As the priestess I am but a servant of the gods, I can not favour anyone, I will simply Marry who ever wins" she says with a gentle voice, and sad smile

••• 😐

"Huh.." he blinked in confused to what he just heard "Seriously?...that's weird I could sworn you..." He then exclaimed " hang on! Are you saying you don't care who wins at all?!" Ruri began to panic, sweating a little feeling pressured " Uh!...well..I'm!....yes?" Jasper, who was next to him, gave him a ' are you kidding me look' 'Learn to Read between the lines a little ginro! What else is she supposed to say when you ask her like that?'

Meanwhile ginro was in deep thought, him being the chief, Ruri and the goddess aka yuna at his side as his first and second wife, people bowing to him 'village chief...ginro!' Senku was next to fight him, so he began his March to the centre as Jasper announced "We now begin match two of the semi finals, senku vs ginro, contestants come forward"

Senku barely managed to dodge as the crazed ginro swung his staff forward, missing and hitting the floor

"What the hells gotten into you ginro?!" Senku exclaimed, blocking another attack

" what do ya mean?!" Ginro Says in a crazed manner, while running after him "You heard the girl Ruri said she'd marry anyone! That means even I can be the village chief! My time has come! It's the age of ginro!" The whole time senku was running away screaming while ginro tried to hit him

" no! you've got to be kidding me!"kinro exclaimed in horror

" is this really happening?!....." yuna exclaimed wide eyed, hugging kohaku terrified, clearly as forgotten her immense strength, Kohaku shuddered at the thought wrapping her arms around the terrified girl " what a scumbag!...."

" if I win and become the chief, well all get to eat ramen every single day!" Ginro proclaimed, ga'nan and suika seemed on board for that " and everyone gets a harem! Just you wait I'm gonna turn this place into the village for all our dreams!~" The girls seemed to catch on to what he was saying, more like him and the men

While ginro kept mercilessly attacking senku as said person was running away from the crazed boy, the villagers could only watch in shock

' ugh...please not him..'

'Ginro...Anyone but you man....'

They all had the same thought ' we can't let him become the village chief!'

"We have to take him down as soon as possible" kohaku stated as the group watched the fight which wasn't looking good " but how is senku supposed to do that?.."

" he's screwed..." yuna stated bluntly

Chrome who was still lying down on the ground, weakly reached to arcs the broken water melon mask, which suika noticed "Senku our...Weapon is science...So get in there and use It!..." with the strength he had he threw it towards said guy

Shocking both ginro and senku, it rolled past his leg and lay in front on the ground, senku smirked "I guess I don't have any other options" he says leaning over it "Huh, You're gonna use some crazy sorcery now?!" Ginro exclaimed, and was full on with his Pursuit, slamming his staff on the ground towards Senku "Well not if I get you first!!!" Meanwhile senku rigged up a contraption with his staff and the helmet, like a seesaw, and when ginro got close, senku stepped on the side closest to him, and the one opposite, flew upwards and hit ginro....

... right in his crotch

Ruri didn't know how to feel about it, meanwhile her after pondered 'He's clever that one...Senku was it?'Ginro stood there, foam coming out of his mouth, he then collapse to the floor, gripping it in pain, Jasper then announced " The winner is senku!" The villagers around began to cheer

"Ginro's down!"

"That means senku's going to the finals!"

"They're United and relieved ginro didn't win!" Suika clapped her hands together smiling joyfully

"And now we can save..." chrome was struggling to keep himself upwards " Ruri..." and then collapsed, yuna gasped when she saw the boy collapse " chrome!" And rushed to his side cradling him in her arms, Senku's eyes Widened when he saw chrome unconscious, after hearing san shout his name the ground surrounded the unconscious boy "Okay, he's completely Konked out" suika says after poking chrome a few times, senku sighs exasperated

"Oh chrome..." yuna says worried

"Maybe the tension was keeping him awake, Once Ruri was safe it all went away" kohaku stated, before pausing, it then dawned on her, she started sweating profusely as did everyone else

"Oh crap..." yuna cursed with a worried smile of realisation

"And does that mean?..." suika shivered, then yelled " senku and yuna have to fight each other?!?"

" There's no way I stand a chance in hell against the wolf girl!!!!" He exclaimed, The faces were drawn and Jasper announced " Final round, senku vs yuna! contestants come forward!"

Yuna panicked and shouted without hesitation "Uh! I withdraw!!!!" She yelled

"Huh?!?!" The villagers exclaimed

" but why?!" Someone in the crowd exclaimed
"I'm sorry but I refuse to harm my comrade and friend!" Yuna yelled at the top of her lungs

...

...

" as expected of the warrior goddess!" They cheered

Yuna anime falls to they're response ' are you freakin kidding me!!?!' Especially after what she heard next

" the warrior goddess is so kind!"

" she could hate to harm someone so close to her! So she forfeit to keep herself from harming him!"

No matter how much it pained him, Jasper then announced to the entire village "The new village chief, And husband of the priestess...is the winner of the grand bout, senku..."

Kohaku and suika gasped in disbelief, followed by her father and sister, and senku was in disbelief

"Huh?...."

________________________________

However the most hilarious expressions in the area, where the ruri and kohaku's father, Jasper and turquoise

'So...' Jasper says in thought

' what..now?..." turquoise wondered, Senku sighed, picking his ear " well this is just great, this just got a hell of a lot more annoying, so just to be clear if I were to marry ruri, then this entire village is mine, is that right?" He asked as he walked forward in front of ruri " then I guess I'll do it" he says giving in, The girls exclaimed in shock " they're married now?!" Suika exclaimed " this is happening so fast!"

But of course, there was drama, and who to start it, kokuyo " hold it senku! Where'd did you even come from Huh!?" He yelled " your an outsider! We can't let you be our chief!"

" my my!~" senku mocked, still picking his ear " If it isn't the former village chief himself, to tell ya the truth I don't have a millimetre of interest to listen to your lack of approval" He stated

Of course this argument started making things more complicated for the villagers, who were trying to confirm who sides with whom

" uhh...who are we supposed to side with?

"We side with kokuyo obviously!!!" Turquoise exclaimed in anger " do I have to spell it out for you?!"

" but the gods are watching, and he did technically just win, even the goddess herself approved"

"Not to mention he's married to the priestess now to..."

"Object all you want to, a win is a win" senku stated with no hesitation and with a dark grin " so chop chop! Bring the winner his booze!"

" can you not?!" Kohaku and yuna exclaimed at his behaviour "You sound like on of those old drunkards who can't get his full!" Kaseki commented, Two of the villagers brought over some pots, and placed them down on the ground, however examined them after noticing something "Hmmm this pots no good, All of its turned into vinegar" the man who examined it stated

"I'll take it!" Senku said rushing over "We need that too!"

All of a sudden ruri began coughing violently and began to fall forward "Ruri!" Yuna quickly rushed forward and caught her

"Not again!" Kohaku exclaimed worried

" are you alright?" Yuna questioned

" ruri..." kokuyo also worried

"It's not that bad..." she assured, yuna looked horrified as she saw blood in her hand ' we're running out of time!...'
Meanwhile senku too seemed to be in thought himself about the situation 'Looks like the clocks...haha...we literally just finished the grand bout, but I guess it's straight back to work...'

"Let's head back and finish the sulfer-" before he could finish, he was cut off by two male villagers approached had approached him
"Hang on, Where do you think your going?" One of them asked "Your the guest of honour"

"Yeah have a drink with us" the other man said

"To celebrate your marriage, We're drinking the night away, It's tradition around here" the same guy from before stated "Yeah, In that case" senku picked his ear, deadpanning

"Huh?"

"I wanna divorce" he announced, Everyone looked at him shocked, ruri including by his sudden announcement, even san was in disbelief, like her brain still haven't processed what he said 'Eh....'

"They're divorced now?! This is happening so fast!" Suika exclaimed

Senku dragged poor old man Kaseki while kohaku and yuna carried the alcohol and vinegar

"Haha! We've scored a tone of alcohol and vinegar!" He cackled as they ran down the bridge "Let's haul ass citizens of the kingdom of science!"

"Excuse me! Since when am I a citizen of the kingdom of science?!" Kaseki yelled as he was practically abducted by the boy

"Since you helped make the glass bottles!" answered for him "I'm sorry ruri!" She yelled her apology to the long blond haired girl "We'll explain later!" Kohaku added, Leaving the villagers gobsmacked "Huh..." turquoise stared in disbelief to what she just witnessed as did Jasper "That guys making a mockery of our ways" he commented

Ruri however smiled awkwardly "I'm still a little confused, But I think I may have just become the first divorced priestess ever" she giggled, then genuinely smiled "Well how's that chrome?" Who was still lying unconscious on the ground, but kokuyo was enraged "This is utter bullshit! Capture them right now!" He ordered pointing in the direction they ran in, but kinro stepped forward "Senku and yuna aren't villains" he stated without hesitation

"Hmm?"

"Please let them explain for themselves What the sorcerers...I mean the the scientists" he corrected as Ginro nodded to every word he said "have been working on, What they bet they're lives on for half a year, What I've seen them do..."

Time skip

The group was now gathered at the water fall, where old man Kaseki had created some kind of bamboo waterwheel

I still don't know what it is

"What's this?" Kohaku asked curiously

"The force from the water fall is making the bamboo spin around." Suika noted

Old man kaseki turned to them happily, who was also submerged in the water in front of the contraption " aha! And I nailed it on my first attempt! Pretty cool Huh? Are you charmed by my talents ladies?"

" impressive" senku compliments with a grin " I usually bosh my first few attempt at building anything." 

"Thank you, but I wasn't trying to charm you"  the old man replied "So, what does this allow us to make?" Gen questioned out of curiosity  "Well, i know it's spins, but what its for I don't know." Kaseki admitted "Don't worry, You'll find out tomorrow." Yuna replied, ruffing her wolfs fur, who whines happily wagging they're tails

"I think I'll keep an eye on it for a while" kaseki announced "I'd cry if my baby were destroyed by a piece of drift wood or something"

As gen was about to walk away with the others, he suddenly felt a hand holding him back which turned out to be old man Kaseki. "Hey you! Want me to stand guard by myself?! A weak old man like me?! You've got nothing better to do! Stay and help!"

"Huh?!" Gen exclaimed struggling to free himself from the old mans strong grip " is really rather not gramps!"

But once the old mans cloth was ripped, revealing his muscles, he caved " oh...sure I'll help you out....'" he said with a quiver in his voice ' weak old man?!?!'

Time skip

Meanwhile, Suika runs in front as kohaku and yuna carried the unconscious chrome back to the science lab, suika still couldn't see clearly without her watermelon mask and tripped as she got close, but brushed it off and ran inside

Chrome was still unconscious, even after being, suika watches over him as senku came back with Two sticks, which the buds at the end were soaked with ammonia, Senku stuffed two buds in his nostrils, And with that the boy wake up screaming at the putrid stench "AHHH!!!!"

"Wake up and smell the ammonia buddy!." Senku jeered the green-haired man while the girls watched with expressions of shock " we're gonna need you on team science let's go!"He picked up a glass bottle " we don't have much time left, all we have to do is put it everything together and we're done" he then announced " by morning Tom more well have it, the cure all sulfa drug!"

"Tomorrow?!" Chrome exclaimed, In shock, Kohaku was however surprised and excited, with a hint of relief " that quickly?!"

Fun with making sulfa drugs

Step one

"First, we're using using a burnable rock called coal to-" "Burnable rocks!" Chrome excitedly bolted out of the lab into the storage shed to procure the material "Got it! I've got plenty of that stuff!" He stopped when he noticed that the pot in his hand, was completely empty, and gasped horrified "Yeah I sort of figured we must have used it all up when we made iron" senku stated "That's bad!!!!!!" Chrome cried

Senku chuckled as yuna stood at the top of the iron furnace with a bamboo and a clay pot strapped at her side. "Don't worry about it." She reassured while scrapping the insides with the bamboo. "If we need more originally coal like you've had, we'll just take a trip up into the mountains" she said

However she used the bamboo to scrape the tar in the inside " but for now, we don't even need the coal itself, just the tar that's left after its burnt"

After collecting, the substance was now in a Florence flask, before pouring hydrochloric acid in " just wash it in hydrochloric acid" senku explained as he carryed out the procedure. "Then throw in ethyl acetate made from alcohol and vinegar, and we've got aniline." Chrome, however, was still confused about all this. "Wait wait wait! Slow down! You guys lost me like five sentences ago!" he called out. " if that's all step one, and we're done by tomorrow, how many total steps are they're?" He asked " like three or four?"

" hmm, oh only twenty five" senku replied all laidback as he messed with chemicals

"Oh...That's bad." muttered Chrome. " then what are we waiting for?" Yuna asked, before cracking her knuckles smirking "Let's get to work!" And with that the kingdom of science got to work, it was dusk and the girls, excluding suika swam to the bottom of the sea, collecting what looked like a sea sponges as materials

Back at base

Senku placed two Florence flasks onto the ground and then set up the condensing column to carry out the next step as kohaku and yuna arrived with heat they collected, On one of the fires, they boiled the sulphuric acid which caused the vapour to travel through the column.

The vapour soon began to transform into liquid as it slowly dripped into another Florence flask placed in the centre of a clay bowl partially filled with water, also on top of a small fire, Suika helped by dripping water onto the cloth wrapped in the centre of the glass tube

As the night came, The science team continued they're work, along with the help of yuna

Next day

Old man Kaseki had fallen asleep, leaving gen to watch the contraption in his place " I still have absolutely no idea what this thing is, surely it wouldn't hurt to take a quick peek inside" he mumbled as he reached and took out the bamboo off, Casually walking over to a glass flask he had brought and pouring the substance out into it, The liquid was water, but his eyes opened into realisation when he saw it fizzing, carbonated water, the whole contraption he had no idea what it was, finally figured out, a water carbonator

But most of all to him, carbonated water, was an ingredient to make cola, He immediately began running back with the two glass flasks of the stuff

Flash back

To the promise

"Even in this stone world yuna...could you and senku make one for me?...just one...cola..." he asked weakly

She smiles softly "Of course, for sure, nobody else can, don't worry gen, even if senku wouldn't be able to in his time, I'll make it for you..."

He smiled weakly

Flash back end

' careful now! Don't get your hopes up, there's no way he or she are that nice' he thinks, however the excitement was overwhelming him ' right?...' "Senku, yuna~what's this fizzy water for~?" Gen who happily arrived at the laboratory with two conical flasks asked, only to shriek wide eyed at the sight of the unconscious scientists on the ground with bits of material sprawled all over, the wolfs of whining at yuna's state the most in worry

He picked up one of the pieces of broken material after placing the flasks down safely " did a bomb go off in here?..." he asked " there's a lot of collateral amage a...what have you gotten into this time?" He asked

Senku chuckled as he listed his head "nothing special really, just mixing stuff together" he replied, then retraced his steps

"poured vinegar on burned shells, , extracted glacial acetic acid using sulphuric acid, turned into ketene in an iron pipe, and put it back to make acetic anhydride"

" uh...oh..very interesting..." gen smiled sheepishly, not understand at all

" so I tried to drip that acetic anhydride into the aniline. But I poured in way too much. And kaboom"

"I see, hence the wreckage." Gen understood, As a fire outside boiled the substance in a water bath, senku explained more to gen "Mix the chlorosulphonic acid into the acetanilide we just made" As senku continued, a cringe expression morphed onto his face, considering he didn't know a single thing senku was same it can't be blamed " for para- acetamidobenzenesulfonyl chloride. And then. throw in ammonia to get para-acetamidobenzenesulfonyl acid cook it in hydrochloric acid, and get that" he said pointing at the stuff boiling on the fire

"I'm impressed you can say that without stuttering, good job" gen compliments

"Lastly, that carbonated water." Senku said reaching for the flask gen had picked back up to hand over "Oh yes" gen gleaned " I meant to ask, I'm not expecting anything, but is this for..."

"Yeah, what else would it Be for?..." senku traileld of with a warm smile.

" I have no earthly idea"?" Gen replied with the same expression, But was disappointed when senku repied while pouring the substance inside a large beaker. "Mix it with sodium hydroxide to make Baking soda!"

"...baking soda...yes right...that's definitely what I was thinking..."Gen said with a painful smiled

It was finally time, everyone who contributed into creating this had arrived

Chrome and Senku handled the final procedure as the others stood at the side to watch in anticipation "Step twenty five, we wash this stuff with our newly acquired baking soda, and then we sit back and wait"

"This is it" chrome commented, smiling with excitement

All the effort, collecting the iron sand, the ramen stand, the iron rod, the generator, the glass, and acid, plus everything else they made along the way along with the materials they put effort into gathering for this very moment " it took a long, Bad half year"

"It's Sulphanilamide." Senku stated as he poured the substance into the glass flannel " or you could say,..." Once the mixture was rinsed, they finally got a petri dish containing a white powder like substance " the fruits of our labour, The cure-al sulpha drug!"

"Yeah!" Chrome jumping up with his fists raised up high cheering with delight, suika and old man kaseki high fives, kinro just glanced at his brother who cheered for the groups victory, Gen who merely had a closed-eye smile and arms crossed underneath his yukata sleeves.

Yuna smiled And the wolfs letting out they're very own victory howl, tepo included

"We Finally have it..." Kohaku muttered looking up to the sky with a new found hope " and now ruri will...."

" are you crying kohaku?" Said girl flinched when she heard the voice from the top warrior of the group " save your tears for when ruri's well" she said with a smile "Oh! I'm not crying my goddess! Rest assured!" she denied fast with reddened cheeks, waving her hands, while using the other to wipe the tears away quick

At the bridge

" unfortunately..." The group made it to the bridge, however gen stood at the edge, not crossing over " I remain bard from the village, so I won't be able to come see ruri take her medicine"

" sorry gen" yuna apologies " we'll see you later!" She said as she turned and walked with the others "Gen helped us out so much." Suika stated walking alongside yuna " it's a shame he can't come " she said feeling bad for him " don't worry suika" yuna assured confusing the little girl" Huh?"

" I left a little thank you present for Him inside back at the lab" yuna Admitted sheepishly.

Meanwhile

" that's just the way it is for rats like me"gen muttered as he walked towards the lab, only for his eyes to widen in surprised at what he found on the table

On the screen, of you were expecting mecha senku then I'm sorry, little miniature yuna appeared " survival specialist yuna here! To speak some facts, Car donated water, plus cilantro, lime and honey caramel, and you get coal! If you don't believe it, then try tossing some limes zest onto crush cilantro, it will shock you how it smell like it!"

Gen chuckled " that girl..." holding the bottle in his hand, Once he opened the cap, a wide grin stretched across his cheeks before chugging down the carbonated drink, After finishing, in delight, he let out a howl of his howl "Wooohoooo!!!!!!!!"

Back in the village

The group walked  towards ruri, who had kokuyo, Jasper and turquoise by her at the waiting for them

The scientist looked over to the redhead, who gave him a curt nod to which he brought out his pouch, From inside, he pulled out the bottle of sulpha drug, opening it to pour the substance onto a leaf, he handed it over to yuna, who took only one step forward offering it to the girl "Hey, don't Worry Ruri" Chrome assured. "I promise you, this is the powder of life, born from stone, it's the cure all of science. It'll knock that sickness right out of you!" 

Kohaku nodded to his words

Ruri didn't hesitate to respond with a curt nod as well, the goddess was who had eased her pain before during her first visit, she willingly stepped forward Much to the adults' surprise, and sat on the stool to accept the medicine, She opened her mouth, allowing yuna to pout the medicine down her throat.

' a mystery bug verses the combination of two million years of humanities scientific endeavours, time to get excited' After swallowing the last of powder, yuna walked behind her  "Alright, ruri, time to make a diagnosis, just relax while I press this on your back" she said as she placed the beaker against ruri's back, who let a startled Yelp escape her lips , with reddened cheeks "Now please say Eeeeeeeeeeee. Loud and clear" Unbeknowning to the redhead, everyone else - with the except Senku - was just as flustered at her actions as the priestess who obligingly and meekly repeated, "Eeeeeeeeee." 

Yuna had her ear placed against the base of the beaker while covering her other ear with her free hand, Something wasn't right about the sound Ruri made. ' sounds like a bleating goat.' she noted 'That's proof there's fluid built in her lungs. But, what's the cause?' She eventually got her answer when she turned around and saw a rat's carcass, and a skeleton of one

Back at the lab

Later that evening, the group had returned to the laboratory, But this time, yuna was the one working on this discovery, She had brought back a bundle of cloth wrapped around the carcass of the dead rat " I'll just come out and ask" gen says breaking the silence " why do you have that rat yuna?"  As said person had her long hair tied in a bun, wearing a surgical mask and Gloves

"Maybe we're eating it?" Kohaku inquired, with a finger on her chin, catching him off guard as he snapped his head at her " uh! It's incredible that's the first thing that comes to your mind"

"Trust me, rats aren't exactly a part of my diet." she reassured cheerfully. 

"That's comforting to know." said Gen with relief, until she said " usually.,."

"Oh yes... usually... it right.."

"They are a valuable source of protein." Senku chuckled. "But we're not here for a meal right Wolf girl?" As the girl held a mini scalpel she'd made "Yeah...." she replied

" what yuna is doing is an autopsy" senku explained as the girl dissected the rat with a clean cut and then opened it with her forceps.

Her eyes widened with shock and worry ' red inflammation all over the lungs.' she noted. 'It's definitely a bacterial infection. To think that this rat was found near Ruri's house worries me. If this rat is also infected, then I'd say Ruri has the same bacteria like this one.'

  "So what's the verdict?" Senku asked

As the group stood outside the lab as free yuna cleaned up " we need to narrow it down more." She said confusing the three but senku"Even our the cure-all drug has its limitations. It isn't ten billion percent guaranteed that it'll wipe out this specific bacteria. And in the worst cause scenario...if our enemy is Mycobacterium tuberculosis, there is nothing we can do in our current state." she added grimly gripping her fist

Kohaku and Chrome became worried, all of a sudden

"Quick! You guys got to come with me !" Suika cried as she ran towards them. "It's ruri! She's gotten worst!"

Back at the village

Ruri violently cough, wide eyed, hands clenching around her mouth, with the three aunts word I'll get terribly

"don't get up! Just stay on your side like this and try to breath slowly!" Kokuyo instructed as he had her rolled on her side

" it's never been this bad, never..." Jasper remarked worried "I can't help but feel the worst here..."

"She had that white powder!..." turquoise grot her teeth " and now this starts happening?! I knew not to trust in they're sorcery medicine!"

"Ruri we're here!" Chrome called worriedly  "just hang in there!" followed by Kohaku

Senku's eyes widened before he knelt to the ground, with san standing beside him just as silent.

Kohaku noticed this as her concerned gaze landed fixed onto them. "Senku? Yuna?" she muttered hesitantly.

"Senku, you bastard!" Kokuyo yelled reaching for him, only for yuna to step in front and catch his hand "Get out of my way!" He barked at her

" father!" Kohaku exclaimed

" if you hadn't given her that! Ruri wouldn't have taken such a drastic turn for the worst!"

" calm yourself and listen!" Yuna glared daggers

"Yeah, your probably right." Senku calmly responded, much to everyone's surprise.

"So you admit it!" The chief hissed

" listen you damn fool!" Yuna barked the same voice volume he did before " The bacteria are getting worse! This is because it's making allies by spreading its toxic genes into the harmless bacteria all around it!" She says as ruri heavily breathed after the violent coughs, Senku kneeled down to her " it's the signature move of the new pneumococcus bacteria's..." he says with a grin "which means that ruri's disease is... pneumonia. And that's nothing to laugh at, it's a deadly disease with a kill count of hundreds of million....but sulpha drugs absolutely slaughter pneumococcus bacteria!" He announced with a fist

"Which means that we won, with the power of humanities science!" He got back up "Now that we know what it is, we've got the upper hand, all that's left is to pump her with more sulpha drugs." 

Kokuyo however wasn't enthusiastic, more like an animal blind by rage "Enough of your trickery!!" And tried to attack senku again, only for yuna to once more intervene, but this time she had reached her limit "I said enough all ready!!!!!" And threw him over her shoulder to the ground, much to the others shock

"Chief!" Jasper and turquoise tried to rush to his aide, only to flinch and stop when they heard a powerful voice which belonged to the redhead "Don't you dare!"

She glared down at the man "I have had absolutely enough of you! I've held my self back from doing this" she admitted "but you've exceeded my anger limit! Don't you dare lay a hand on him or anyone that contributed to making the medicine! They've all worked really hard, kohaku most of all from the very beginning!" As she said that, said girl being talked about looked rather surprised

"The only thing she's done before we arrived is protect ruri and try to find a way to save her! Just Like chrome! Who tried to find the medicine to save ruri!" Said boy also flinched surprised when she mentioned his name  "kohaku's endured so much! Even after you've threatened to disown her! And to have ruri married to a tyrant like magma! Who would have just let her die! Even if they disease hadn't killed her, he certainly would have! Do you know how much your daughters gone through just to save her sister?!"

"Yuna...." the blond girl breathed

Senku snickered at the redhead who was enraged "And that's why you never make a Wolf girl mad" he stated as she continued

"You may be the village chief but most of all your a father! You may care for the villagers and your daughters! But being a father is important as well!  We never came here with bad intentions! So why can't you see that!?I don't care what you say or need your damn permission! The night I left the village i made a promise! That I would make sure ruri gets cured! And I always keep my promises"she said
"And anyone that tries to get in my way...god help you cause I won't be merciful..." she Says in a low dark voic, releasing him from her hold and standing next to senku in case he pulled anything again

"Father, This is nothing like the frogulent sorcery that you know!!" Kohaku stepped in, shocking the man, she continued, "It's science the culmination of human wisdom. And I believe in it, I trust and believe in Senku and yuna"

"That's right!" Chrome chimed in "So do i!" Kinro, Ginro, and Suika nodded curtly

"Not entirely sure why, but i do too." Kaseki added, The two adults in the back stayed out of it and lead it up to kokuyo to decide, he looked to the two outsiders and decided

Next day

The next batch of the drug was in the making "I gotta say, it's a miracle that ruri managed to live to eighteen" senku comments as he pouted the liquid, While he and chrome worked on the drug, yuna stayed with ruri to keep an eye on her, with the help of kohaku " bit of you stay clean and keep warm, the diseases Progression slows significantly, turns out that hot spring water that kohaku hauled in everyday, ended up helping her sister a lot more than she knew"

The same thing she did when she first met with her, helped with cleaning, and keeping her warm, then when the sulfa drug was complete, she'd give it to her, it made her feel embarrassed a little, but Soon

To kokuyo's shock, ruri was cured, standing tall and happy, not a single cough escaped her mouth, not only that, she was standing outside the village for the first time in so long "Ruri...Ruri..."The father fell down to his kneels sobbing

Even Kohaku had tears streaming down her cheeks, Ruri went over to hug her sister

Even Jasper and turquoise were crying happily

Ruri glancing at Chrome with a knowing look, to which he returned with a curt nod and a smile on his face.

Ruri went over to her father and said something, that made his eyes widened, tears still leaking down his eyes, he stood back up glancing at the two who were talking

"I can't even remember how long it's been since I've left the village and been Able to run!" she said happily before suddenly speeding off, Everyone and the animals was caught off guard by energy "I know that rambunctiousness, It must have actually run in the family all along" old man kaseki commented

Back at the village

Back at the village, kukuyo raised senku's hand up to the sky and announced to the whole village "Everyone! as of now! This man known as senku! Is pronounced the new chief! Of ishigami village! And has brought peace by the hand, that saved our lands from the wicked beast! Our warrior goddess, yuna!"

The villagers cheered, however senku and yuna were in shock after hearing the name of the village "ishigami village?...."

"That's right senku" ruri says, appearing behind the two, surprising them "I know of you and yuna, have for a long long time
Since I was a child....

....Your full names Are ishigami senku, And Suzuki yuna"
