Small note: (y/n) isn't able to teleport anymore, because I find that she has way to many superpowers then, but she is able to fly really fast (only short distances though), to make up for it, kay?

After dinner (which was delicious, Saitama could cook really well (unlike when you were young and he almost lit the house on fire)) you and Sonic went back to your house. You were planning on just watching movies for the entire night, but as soon as you were ready, the power went out.

Sonic was about to call it a day and wanted to go to bed, but you weren't done with him yet. Besides, it was way too early to go to sleep and you'd been unconscious for four days, so why not?

"Hey Sonic-chan" you said, grabbing his arm, so he couldn't run away. "I want to ask something"

"What is it, (y/n)?" he answered, but the fact that he didn't use your nickname was enough information to understand he already knew what you were going to ask. He probably didn't want you to know, so maybe he hoped you'd ask something else, but you didn't.

"What happened in your past and why won't you talk about it? You can trust me, you know?" you asked, and he froze.

"Why do you want to know?" he asked.

"Don't dodge the question like that. I've already told you about my past, so now it's your turn"

He sighed. "I guess I can't escape it then. But it isn't happy"

"Yeah, my own life wasn't that happy as well, with all the bullying and suicides and stuff"

"Why did you use the plural of suicide?"

"It... I'll tell you if you tell me about your life first" you quickly said.

He nodded. "Okay then"

You took a sip of your (f/d) and waited for him to begin, it was clear he wasn't sure how to start.

"So I grew up in a ninja village, where I was taught everything I know, including my abilities to run faster than sound"

You nodded.

"I was quite good, to be honest" he continued, "but there was one girl who was almost always way better than me. Since we only use names like my: 'Speed o' sound Sonic', I don't know her real name, but eventually, we fell in love. I was quite a happy time, until our instructor died and we got a new one. The first one was really kind, but this one believed that you needed two things to train people: rewards and punishment. He always gave us much more punishment, so that we'd really want the rewards and obey him" he folded his hands and looked at you. With your eyes, you begged him to move on, so he continued. "It made us really strong, but we were beaten up really bad every day, until the point where some of us started running away. After a while, only five of us remained, including the girl and me. The fact that only five of us remained made the instructor really mad at us, because he believed it was our fault the others ran away. So he killed the girl to set an example" he'd reached the point where he was just staring in the distance, his voice almost monotone. Without even giving you the time to act, he continued. "That was the moment when I snapped. I killed him, without any hestitation. There my road as an assassin began" he stopped talking for a few seconds. "Since then, I've killed many, trying to make others feel the pain I feel inside"

You wrapped your arms around him, and to your surprise, he started crying. The almighty ninja Speed of sound Sonic was crying in your arms.

"I know it sounds stupid" he softly said, "and others will have been through more, but-" he was interrupted by your door opening.

"Crap" you said. These were moments you didn't want others to see, the moments where you seemed weak.

Saitama and Genos walked in, looking for you and Sonic. Since the power was out, there was barely any light, just some moonlight coming from the window.

"(Y/n)?" Saitama said.

"I'm here" you answered, turning at them from the couch. "Also; do you know how to 'knock' on a door? Most people like it if you do that"

"Did we interrupt something?"

"Yes. Yes, you did" you coldly said as you turned back at Sonic, who had wiped away all of his tears and looked normal again.

"What are you doing here?" he asked.

"We were just checking if you were okay" Genos said. "Since the power went out"

"And why didn't you come here earlier?" you asked, placing your hands on your hips. You were quite annoyed at them. Again.

"Because there was a monster that attacked us" your brother answered quickly.

"Yeah, right. You can beat every monster in two seconds and you needed... Let's see..." a small ball of fire appeared above your watch, so you could check the time. "25 minutes to come here" you continued, making the fire disappear.

As he was about to answer, something shiny flew through your vision.

"What was that?" you asked.

"What was what?" Saitama said.

"I saw something shiny fly that way" you said, pointing to the left.

Everyone looked that way, as suddenly, a huge explosion appeared, sending all of you crashing against the wall.

As you tried to get up again, you noticed that the shiny thing you saw had grown into a giant... Well, whatever it was. It looked like a giant rhino, but it was bright green, standing on his hind legs and some parts of his body were like mirrors. It was really weird and ugly. The shiny thing was probably a part of the mirror-like things, or something else.

"See?" Saitama said. "Told you there was a monster"

"Sensei, this monster was not the one we just beat. The one we killed was much smaller" Genos answered.

"Shut up" your brother said, turning red.

"But it looked about the same. The only difference is that it was brown and less... Shiny..." the cyborg added, ignoring the last comment. "Is this it's mother?"

"Probably" you said. "Well, at least it's the same kind"

"Does it matter where it comes from?" Sonic interrupted your conversation. "We should just kill it"

"Indeed" you said. "Let's kill it"
