Millions of decades ago, Y/n was well known for his massive killing, cold blooded heart(u have 6 hearts just like 7ds), and his trickery. People all over were terrified of him, even some overlords because of how cold he was. Not like the other demons. But ever since then no one has seen him. And he has changed his name and appearance. (Yes. To look like a low life demon, bc he doesn't like the attention sometimes)

As y/n was was walking a random demon bumped into him.

Random demon pov
As I was walking with my friends we turned the corner and I saw just another low life demon...tch.. he even looks weak.
"Hey, guys.Watch this." I said quietly to them and they heard me and watched. We all had a wide smirk. As we got closer to the demon I knocked him down and started laughing, so did the others. "Heh, he's so Pathetic." One of my friends say.  "Ikr. Let's go, he's a waste of time." Another one of my friends said then we started leaving.

Y/n's pov
I was just wondering around when some demons came around the corner. I noticed that one of them noticed me. As I kept waking I also noticed how close they were getting to me even though I was on the other side of the (the other half of the sidewalk) so now I'm sure they're headed my way. One of the demons whispered something which I heard. They all had smirks on their faces. He then knocked me down while the others watched. My eyes widened a little but not where they could see it. They all laughed at me. "Heh, he's so pathetic." One of them said. "Ikr. Let's go he's a waste of time." The other friend agreed and they started to leave.

I've been hiding my Aura ever since I left. But I was so irritated that I didn't know my Aura started showing. Meaning any overlord that's around would sense it and know it was me, bc ofc I've talked with them before.

"I really hAte demons like you..." I said as I got up from the ground. They all stop laughing and turned around to look at me. Startled by a demonic voice coming out from me the big looking demon spoke. "What did you just say...?" He said angrily. 

I turned around coldly, walking up to him, grabbing him by the neck, and squeezed hard. "L-let....go." the demon cried out. "You're always picking on low life demons, and yet... you're one yourself." I said sarcastically. "You act like you're above others...*I look at his friends and smirk widely, they flinch*..heh~, he's so... pathetic." His friends were to scared to help. "What? You guys weren't scared a few minutes ago, what's wrong??" I said making a sad yet happy face. "Hey, guys! Watch this!" I then squeezed his head neck so hard his face turned a deep maroon. Then his head popped of and I dropped his lifeless body like a ragdoll onto the ground. Hid friends looked gross out and terrified for their lives at the same time while I was laughing like a psycho they started running. "Aw, where you guys going......... let's play." I said with a with a wide smirk as shadows came from me running at them with a black Aura. I'm pretty sure you don't wanna know what happened. It was too gruesome. I waited, wondering why my shadows weren't coming back to me. Then I turned around and started walking away...then I  heard a little muffled scream, almost like....."Hm~."

I slowly walked towards the place I sensed my demons at. To be honest I was kind of mad that one of them disobeyed my orders. As I turn into an alley way I see some of my shadow demons bullying, clawing at what looks like a child, a little girl demon. My eyes turned a deep red as I said "what do you think your doing." Some were already facing where i was coming from, the rest turned to face me and bowed, moving out the way. "Hg fvhdh skttup.(I'm sorry master)" he said then I started laughing and he got scared. I then stopped laughing and had a smirk on my face. "Oh don't worry." My smirk grew wider. "You'll make it up to me.......by the pit...won't you?"
He didn't say anything. I gave him a cold hard stare and stopped smirking, making a serious face. "Won't you..?"
"G-rsh jsgtiw.(y-yes m-master)" "the smile happily (coldly) at him. "Good.~ now go get your punishment." I said and he left through a portal on the ground, the rest went through me.

The little girl was looking at me terrified, so terrified for life that it looked like waterfall falling from her eyes. I turned to leave but before I do I smiled at her, she calmed down a little and I started walking off. She then spoke, nobody could hear it...but I could that's how quietly she spoke...
