Serotonin {Senku x Reader}

Part 26 - Nikki

"Senku.... I.... Y/n!! Y/n, Senku.... I'm..."

"I'M SENKU, Y/N!!"

Taiju's voice was cracking just like depetrifying stone as soon as Senku picked up the speaker. Y/n wiped away tears of joy as she laughed at Taiju's inability to form sentences. Senku gave the speaker a contradictory look.

"You're not Senku, I'm Senku. What the hell are you on?"

"Sorry, I'm just so overwhelmed....!!"

"In one year, you both managed to make a cell phone, didn't you? Wow... that's too amazing. I mean, I already knew that, but still...!!" Yuzuhira exclaimed softly. Y/n proudly put a hand on Senku's shoulder, grinning uncontrollably.

"Yup, that's our Senku!"

"Y/NNNNNN!!!"

"Jesus, calm down you big oaf. While finally connecting this damn thing has me trembling with emotion, there's no need to spend eons reminiscing over nostalgic memories—"

"Yes there is!" Y/n exclaimed indignicantly, taking the receiver from Senku, "We'll all catch up after Senku gives you his plan!"

"That's a waste of battery, stupid," Senku sighed, snatching the receiver back. "Anyways, I'll give you the important bits. All you two need to do is bring a member of the Tsukasa Empire, give 'em whatever reason you like, just bring them to the phone. I'll give you the rest of the details later. Actually, just Yuzuhira, the less Taiju knows, the better."

"That's kinda mean..."

"Well, if Senku says this is what we need to do, we can definitely do it, no questions asked!" Taiju's staticky voice said from the other end of the line. "Just one last question!"

"You said no questions asked..." Senku pointed out. Y/n elbowed him in the side to shut him up.

"Go ahead, Taiju!"

"This plan... will have the least blood spilt, right?"

Even though the audio quality of the phone sucked, Y/n heard his voice as clearly as if Taiju were in the same room, speaking to her. Senku chuckled, staring off into space and smiling.

"That's right, you big oaf. No worried there."

"Then we're all good! We'll call back once we have someone!"

"Wait! The nostalgic bonding!" Y/n cried. Taiju laughed from the other side.

"Don't worry, Y/n, we can have that once we defeat Tsukasa!"

"Aww, okay! But you both better not get caught!! Stay safe."

"Yes ma'am!" Yuzuhira replied, and Y/n could practically sense her salute like a soldier on the other end. Those two really had a way of warming her heart. Senku, on the other hand, was unaffected.

"Alright, enough with the nonsense. Talk to you both later, yeah?"

"Right! Bye Senku, Y/n!"

"Byeee!"

"Bye...!"

And then Senku hung up. Y/n looked at the phone longingly, as if they'd call back immediately. Senku sighed.

"We'll see them again. Right! Now all we have to do is wait for Gen—"

"I heard my name."

In the doorway stood an exhausted, but relatively unharmed Asagiri Gen. Y/n leaped up and threw her arms around him when she saw him, overjoyed that he was safe.  Upon closer inspection, she could see that Gen likely sprinted back to them.
