Killua as Bakugou (MHA X HxH)

~Chapter 6~

"hey ponytail" he really didn't want to talk to momo, but he needed her help. She opened her dorm room and blinked at him, "Bakugou? Gon?" she furrowed her brows. "is that a child?" Gon was currently holding Eri while he did the talking. "look, as much as I don't really like you, I need something" she crossed her arms. "like what?" he gestured to Eri. "well, I need a tracker. This child's got some people after her and if she gets caught I'm gonna snap" Gon put a hand on his shoulder. "actually can we get three? I just think it's safer" Killua blinked at Gon. "hah?" he smirked, "one for each of us, if I remember correctly you always said you'd get me a tracker" he frowned. "why the hell do I need one?" he snorted, "so if you get kidnapped again I know where you are" momo handed them three trackers and two locator things. "here, also I made some clothes for her" she handed them a bag. "ok thanks bye" he walked away with all the items as they made their way to Killua's room. He infused each tracker with a little aura, then placed one on Eri's stomach. "never take this off, if you ever get lost press the button ok?" she nodded and he put one on Gon's waist. "that one's yours" Gon put the third one on his chest. "there!" he handed Gon one of the locators and he pressed buttons to see how it worked. "ok, so try pressing the button on your tracker" he poked Eri's tracker and there was a click, then her dot started to blink and the locaters made a beeping noise.

"ok great" he turned to Eri, "just so you know, I go by two names" he pulled out two pictures, one of bakugou and another of Killua. "this is me, but I'm called Katsuki, or Kat" he pointed to the other one. "this one is Killua" he crossed his legs. "you can still call me Oni-chan, but if you need someone to get me just say kat or Killua ok?" Eri nodded, then pointed to the pictures. "kat, and killua" he smiled. "good job, now this is Gon" he gestured to Gon and she nodded. "Oni-chan's friend, Gon" Eri glanced at the bag and he opened it. "here's some new clothes for you" he helped her dress and Gon awwed at how cute she was. She was wearing a small hoodie and baggy pants. "you're so adorable" Gon pulled out his phone and took a picture. "wait, wait, Killua do your monotone expression again" he let his face fall into his monotone expression and crossed his arms, he wasn't sure what Gon was planning. "Copy him!" Eri's arms crossed just like he did and also copied his expression. Gon snapped another picture and grinned. "that was so cute" Eri blinked, "but I didn't even smile" he grinned. "if you use that expression all the time you don't need to smile"

He let Eri watch him get dressed as Katsuki, so she understood. "woah, Oni-chan looks so different" Gon placed her on the bed and gave her a tablet, which he had no idea where he got it from. "me and Oni-chan have to go, just play and watch videos on here ok?" they left the dorm room and were halfway down the hallway when their locators started to beep. Killua bolted down the hallway and slammed the door open to see that Eri was sitting on the bed, alone in the room. "i-I'm sorry, I just wanted to-" he walked over and gave her a hug. "I get it, you want to know your safe. But you can't push the button unless of an emergency ok?" she nodded and he pulled back. "I'll come visit you during lunch blueberry" as he made his way out the door Gon took his hand and he let him. "did you just call her a blueberry?" he smiled a little, "I think it suits her"

The next day in class people kept talking about how good some of them did at their work studies. What irritated him was that nobody mentioned the fact that he actually did more than any of them. Without knowing, Killua had stopped the production of quirk erasing bullets. His ears caught what Kirishima was muttering about, "I still dunno what happened with his quirk, so weird" he sat up straight and locked eyes with Kirishima. He pointed to his desk and he walked over, "you need something?" he crossed his ankles and narrowed his eyes. "you said something about someone's quirk acting up" Gon was suddenly attentive. "did it happen to disappear?" Kirishima's eyes widened. "how did you know?" he growled and clenched his fist. "damn him" Gon decided to explain, "so apparently this guy is making quirk erasing drugs out of a girl's blood" Killua clenched his teeth. "I can't stand people who use children like that" Gon put a hand on his shoulder. "calm the hell down kat" he took a deep breath and put his hands behind his head, "wait, was that the girl who called you Oni-chan?" he nodded. "yes"
