Constant Variable (Senku x Reader)

4: Weapons of Science

"Hey!"

Just then, Taiju appeared with his loud voice, causing all heads to turn in his direction as he came running towards them with tears in the corners of his eyes and a wide smile on his face.

"Good news, everyone!" He skidded to a stop in front of the group and in his hand, he held up the jar of nitric acid collected from the cave. "We have a full pot of miracle fluid from the cave! We can finally revive Yuzuriha!"

(E/C) eyes widened in horror while Senku's jaws dropped wide open in disbelief shock that Taiju had literally foiled his plan without even knowing that he did so.

Said person blinked his eyes once, wondering what had caused such a dramatic reaction from his friends. However, before he could ask, Tsukasa opened his mouth to enquire about the revival fluid.

"What's this 'miracle fluid' you speak of?" His eyes, gleaming with curiosity, were fixated onto the jar in Taiju's hand.

Senku startled, his eyes instantly meeting Tsukasa who was already staring deep into his gaze, a deep frown on his handsome face. On the other hand, you immediately froze, unsure of what to do or say, however, Senku was quick on his feet.

Chuckling, he cracked his neck in a casual manner like he usually did. "Let's not waste time standing here explaining it. It'll be ten billion times faster to just show you. You'd better feel honoured to see this. Time to enjoy the humanity revival show."

Without waiting for any response, he turned on his heels and headed for the tree where Yuzuriha was resting against, expecting Tsukasa to follow him.

You regained your senses and smiled uneasily at the other teen before dashing after Senku who was whistling a happy tune as though he didn't have a single care in the world. If only you could be as laid-back as him in this kind of situation.

Soon, all four of you were gathered in front of Yuzuriha's stone body. Taiju handed the jar to Senku who took it wordlessly and got to work on filtering the nitric acid.

All right, Yuzuriha." Taiju grinned blissfully, his cheeks painted a light pink as he held Yuzuriha's body upright against the tree trunk. "We're finally going to save you, for real this time!"

You giggled at your friend's lovestruck expression before turning your focus onto Senku who was transferring the liquid into a larger pot filled with tiny stones, a concentrated look on his face.

"What the hell?" He frowned as the last few drops trickled out of the small jar and into the pot below. "This is just short of enough revival fluid for one person."

"What?!" Taiju startled and released his hold on Yuzuriha, her stone body dropping to the ground with a loud thump. "Did I take it out too soon?!"

You furrowed your brows in worried. "Do you want me to go and fetch some more?"

"You're too slow." Senku was quick to reject the idea and instructed Taiju to go instead. "Tsukasa, (Name) and I will play word games or something while you go get more. So make a mad dash, big oaf."

You saw how his gaze slid over to Tsukasa who was placing his spear against the weapon rack and immediately, you caught on to what he was trying to do. So, you played along.

"Yeap, you should be the one to get it since you're faster than me like what Senku said." You smiled embarrassedly, rubbing the back of your neck. "I'll also probably just end up tripping over a rock or something and spill everything which will be a huge waste."

The scientist's lips curled into a teasing smirk, but his eyes told a different story as they gleamed with pride. "Finally admitting you're a clumsy ass, huh."
