I stopped eating and looked at her. 

She was still eating the food, acting like everything was normal. 

Didn’t she just say that I had no emotions? How did she even find out?

She looked up from her food, still chewing the food inside her mouth.

“What? You thought I wouldn't know? It was painfully obvious, y’know? Pretendin’ to like my food, not carin’ about May being depressed about both of your parents dying 10 years ago, and you can’t sleep because you're a cyborg, right?”

“I was that obvious? And I thought I was doing a great job.” I let out a sigh. “So you gonna do it now, or what?”

“Now.” 

“Sure, let me open the door first.” 

I got up from my seat and walked up to the door, opening it. But right after I did that, I felt a huge gush of wind coming at me.

It was Yuki, moving so fast my sensors couldn't detect anything.

I saw her fist coming at me, but fortunately, I blocked the attack with my right arm.

Her punch was so strong that it grazed my skin. My skin was very tough, so tough it could withstand hundreds of bullet shots without getting scratched.

But the problem wasn't her strength; it was her speed.

My sensor eyes were built with Japan's top-tier technology. The sensors were so advanced that they could analyze anything, even if they were on the other side of the Earth, and they could even measure speeds up to Mach 5.

But Yuki...

Yuki went faster than Mach 5. I do not know the exact number, but it was definitely faster than Mach 5.

"Calculation... Finished. Yuki sped up to Mach 25. The strange gush of wind before she punched you was her speed going so fast that the air followed her movements and hit you."

Thanks for the information, Chikou.

It was very useful.

But back to my fight.

The punch not only grazed my right arm, but it also sent me flying into the air, but I stopped myself.

Before her punch landed on my right arm, I also shielded the whole apartment inside out with a damage-negating forcefield so the shockwaves from her punch didn't just obliterate the whole building, though soundwaves and air can still pass through.

I disabled the forcefield and used my flight to get back to the ground.

“You almost destroyed the whole apartment, Yuki. Our neighbors are going to get annoyed.”

“Then let’s take this to the mountain you almost destroyed days ago.” She said as she used her thumbs to point in the direction of the mountain.

“Sure, let’s.”

She jumped forward and grabbed my face, landing on the half-destroyed mountain and slamming my head against it, creating a crater as big as an average house. Her strength and speed were incredible. I used my sensor eyes again to measure her power level: over 20,000.

I fired a large light sky blue blast towards her head, but she easily dodged it.

“You dodged my light beam? You're way too fast, and your strength could destroy a small building with one punch.”

“I know.” She said as she gripped harder, tightening her grip enough that my words were muffled a little.

“Well, in that case, I can't win against you, you're holding back, and I still can't match up to you; you’ll demolish me,” I said truthfully with my poker face.

“I was just testing you out to see if you're strong or not, n plus, I was getting you back for not caring about May when she cried. You're her older brother, it’s your job to care for her, she’s your cute little sister, y’know?” She said as she let go of my face and got off me. 

I brushed the dust off my clothes as she did that.

“Yeah, I guess. Anyways, what made you so strong?”

“Do you really want to hear my story on how I became strong?”

“Why would I ask that question then?”

“Okay, well, it all started 12 years ago…”
