Killua X Reader [An Endless Bond]

[40] Tension

Your complex expression didn't go unnoticed, as Killua looked at you worriedly. 

"Well, we gotta start training as fast as possible first!" Senka smiled, standing up. "We'll teach you guys as much as we can. Of course, you'll be helping us get stronger, too!" 

You looked to Senka, who had a big grin on her face along with a thumbs up. Ryu wasn't really looking at you, but you could see a quiet fire in his eyes. You then looked to Killua, who gave you an encouraging smile. 

You eventually found yourself smiling back. "You're right. Then, we can find Sanguis together–"

"And take him down! Once and for all!" Senka added, punching the air.

Ryu nodded, a determined glint in his eye. "I'm down."

"Alright! So now that we know how strong (Y/N), Killua, and Alluka are, we can start training together tomorrow!" Senka said, nudging Ryu. "We might actually be able to defeat Sanguis with them, don't you think?"

"Yeah, that's great," was Ryu's mere reply. 

An irk mark appeared on Senka's forehead. "Hey! At least sound more excited about it! I know you want to defeat him more than anything!" 

"Geez, you're so loud and annoying, Senka." Ryu sighed, turning away.

"I'm loud and annoying because of YOU, Ryu!"  

"Oi, keep quiet! You'll wake Alluka!" Killua interrupted, glaring at the two Bounty Hunters.

Meanwhile, you sweatdropped. 'Tomorrow's gonna be a long day...'

The next day, you all gathered by the big forest clearing. It was the crack of dawn, as the sky was only starting to turn orange. 

"Senka, why'd you call us here so early?" You ask, yawning and stretching your limbs.

Alluka nodded, yawning as well. "When Onii-chan woke me up earlier saying we had to meet you guys, I was so confused! It's no fair you all agreed on that while I was asleep–" she pouted while stifling another yawn. 

Senka chuckled. "Sorry about that Alluka. We, especially Killua, didn't wanna disturb you," she said, smiling apologetically.

Killua sighed at this as he scratched the side of his head in annoyance. "Seriously, you guys were so noisy. It's a miracle Alluka was able to sleep through all that." His eyes were clear and alert as he said that, despite how late he, and everyone else, stayed up last night. 

You tilted your head at this. "Killua, you look pretty awake, considering how early it is."   

"Hmm?" Killua turned to you. "I'm pretty used to this. I can last a few days without sleep." He shrugs.

You gasped in awe. "What?! That's no fair, but at the same time, that's really cool!" You exclaimed, as your eyes lit up, making you feel more awake.

Killua, taken aback, froze for a split second. "C-Cool?! No, it's not! It takes a stupid amount of training to get to do that, geez..." he stammers, averting his eyes as heat rushed to his cheeks. 

"Oh! If that's the case, Killua, then you'll probably have an easy time today as well!" Senka put a finger to her chin. "Actually, nevermind, it really depends. Ryu could give you a hard time!" She laughs.

Ryu sighs. "Senka, you could give them a hard time too, you know?" 

"What? Me?" She waves a hand dismissively while rolling her eyes playfully. "Nah."

Alluka tilts her head. "But isn't Senka's ability mainly for information gathering? How is that gonna give us a hard time?" She asks.

Ryu looked at Alluka with a raised eyebrow. "If Senka only had a lame ability like that, there's no way I'd let her work with me. She wouldn't be able to fight," he said matter-of-factly, earning a furious glare from Senka.
