The Little Sister | A One Punch Man Fanfiction

Chapter 18

"... I hate you.."
"I love you too, bro!" I shot back, laughing, eventually making my brother laugh as well.

Our laughter began to die down, but the smiles on our faces stayed. He opened his mouth to speak, but then we heard someone's phone ring. We both turned to where the sound came from, only to see Genos answer his phone.

"Hello?" He spoke, only to be followed by silence. He listened to the one speaking in the other side, occasionally nodding his head. We were about to turn our heads away but then he suddenly had a serious look on his face.

"I see." He spoke again. "Is it alright for me to bring two A class heroes with me? I believe that they would help a lot."

He became silent again until a "Understood" escaped his lips. He then hung up, and kept his phone.

"So, what's the problem?" Saitama asked as Genos quickly continues to do the dishes.

"Apparently two powerful beings are creating havoc in City Z. The disaster level is Demon, and the people are already making their way to the evacuation center." He informed.

Saitama and I quickly stood, "I'll go and get ready." We spoke in unison before we both ran up the stairs, and straight into our rooms.

Thinking that the long sleeved white shirt was enough, I simply put on my tailcoat jacket, after I attached my hidden daggers. I changed out of my sweatpants, and put on my black shorts. I quickly put my belt on, before I put on my boots, and gloves. Once I was done, I ran out of my room, not bothering to retrieve the rest of my daggers.

I began to tie my short black hair into a small ponytail as I walk down the stairs.

"Let's go." I announced as I walk into the living room, where Genos was waiting with his suitcase, followed by my brother.

Genos nodded before we ran out of the house. I quickly locked the door, before we began to follow Genos, who knows where the threat is.

"This is annoying." I heard my brother commented. "They just had to attack on your day off from training."

"So, can you tell us more about these threats?" I asked him as we ran, ignoring my brother's comment. Well THEY ran, I used my rollerblades.

"There are two of them, and both are apparently 10 meter tall. One of them has red skin, hair of flames, wielding a burning battle axe, while the other has blue skin, raven hair, wielding a mallet." He informed.

"Sounds interesting." I commented. "Let's hurry up!" And with that we sped up.

Soon enough, we were in a part of the city where mostly everything was destroyed. There were flames everywhere, and what stood in the middle of it all were the two threats Genos told me about earlier. The red one was to our right, while the blue one was to our left.

"What in the actual fuck is this shit?" I muttered, earning the attention of the two boys, who knew I would rarely curse THAT much in one sentence. "A fire giant, and a frost giant. Like from the Norse myths."

"Norse?" Saitama asked, confused.

"Yeah." I informed him as I swipped both of my hands to their opposite sides, revealing the two hidden blade in the process. "I swear, if the next thing that attacks us are elves, or whatever, I will- well I don't know how I would react."

"Genos, use your fire power on that frost giant." I spoke, pointing at the blue one. "I'll be assisting you. Saitama," Upon hearing me call him by his first name, he turned to me with a serious look on his face.

"You can take on that fire giant alone, right?" He only nodded.

"Alright! Let's go!" And with that, we split up. Once we were closer, I went faster with my blades ready. Before the frost giant could even notice me, I slid past it's two large blue feet, giving him a deep cut on both of his achilles tendon. Thankfully I was able to get out of the way before the blood began to pour out violently from the wound. The giant roared in pain as it fell into it's knees.

Upon noticing that Genos was about to send out a fiery attack, I scatted over to a safe distance, but stopped when I saw the frost giant slap him away as if he was some kind of pesky fly.

"Maybe I should've warned him to be careful?" I muttered to myself as I quickly began to skate back over to the giant. I dodged the giant's hands as it tried to crush me, before I jumped on it's right hand as I turned on ice skating mode.

The giant roared in pain as I ran up it's arm, making sure to leave wounds behind with the blades underneath my boots. Once I was close enough, I jumped, planning to stab it's eye, when his hand came into view. I turned off ice skating mode as I landed on one of it's fingers, before I jumped up to the sky. I prepared myself as gravity began to pull me down, and successfully kicked it on the top part of it's head, breaking it's skull in the process.

I jumped off as the giant began to fall. I tried to stab it in the back so that it would lessen my momentum, but before I knew it, the giant was out of my reach.

I looked down as I swiped my hands, in a way that the blades went back in their hidden state.

"Guess this is where my story ends." I spoke to myself as gravity pulled me down more and more. You know, I've always wondered if there really is a thing called heaven or hell. I closed my eyes, accepting my fate.

I waited for the impact to come, but only felt two arms caught me. I opened my eyes in confusion, only to see Genos, who caught me in mid air when I was only a few meters away from the ground.

He landed safely, leaving a crack on the concrete ground. He then turned his gaze to me. "Were you just about to accept death?!" He scolded.

I awkwardly tore my eyes away, "I might."

I then heard him let out a growl in annoyance, "Don't you dare die on us like that."

"Right, right, you can put me down now." I deadpanned, but to be honest, I was pretty happy.

The cyborg sighed, before he gently placed me down. I stood on both of my feet with ease, before I turned to him and gave him a quick kiss on the cheek.

"Thanks for saving me." I spoke as I pulled away, flashing him a smile as my own face redden. My smile only grew wider at the sight of his flushed face.

I quickly turned on my heel. "Anyways, let's go see if my brother is done with his task." I announced, as I turned on rollerblade mode, and began scatting away, not waiting for his answer.

Soon enough, the cyborg was running by my side, as we head to where we last saw the fire giant. As we ran, the memory of me breaking that frost giant's skull with one kick crossed my mind.

Maybe I am more powerful than I think?
