Your goal was achieved with impeccable skill, intimidating and exciting others, while one was impressed and vowed to live up to your strength. The three that had varying reactions soon became your lose acquaintances in your journey. There were times where you had lost your patience and flicked their foreheads in punishment for causing your headache, but that didn't stop the fun that happened, the fighting and the close calls. 
You ended up finding out that Tanjiro, one of your acquaintances, was finding someone, more importantly a demon. You were tied down just like him, watching one of the pillars cut himself to show blood to Nezuko. You were sure she was gonna devour him in an instance, you looked at Tanjiro betrayed, scared, and pissed off, but before you could kill him she turned her head away shocking everyone. 
When the dramatic impression ended and you were escorted to the Butterfly Estate, you couldn't help, but be drowned in your own hatred. You confronted Tanjiro, taking him by the collar and throwing him out of the room where the boys were staying. He looked at you shocked, he saw your tears, reaching out a hand before he winced, being it back down. 
"Tanjiro!" They heard Zenitsu cry out in vain. 
"Why do you keep a denom?!" You shouted. 
"She's my sister! And you saw what happened, she's different!" He commented. "She wouldn't hurt a human." 
You felt your headache come back. You cradled your head, feeling the lighheadness affect your vision. You passed out in front of Tanjiro, and he called out help in the middle of the night. He's surprised no one heard him impacting the wall. 
Due to your impulsive actions, you now had people watching you at all times, and your recovery took longer. Tanjiro and the others left, when Aoi told you the news, you dismissed it, but you were deeply shocked. . . Maybe you deserved it. You may have been strong then, but now you were weak, alone in the Butterfly Estate being babied. You felt your ears go red, hearing the faint voices in front of your door. You looked over at the small window and a tragic idea struck your head. To be less of a burden, you must take yourself out of the equation. You quietly took off the sheets, opening up the window to crawl out. 
You did it successfully and now you climb other obstacles to be free. You find yourself on a cliff, abandoning everything you have ever known, before you could take two feet to Hell, a voice from behind you startled you. You turned around and the greater evil, the demon of all, Muzan. Your reflects took you to your side, but you were outside with nothing but bandages and thin clothing. He lowly chuckled at your defensive stance. 
"You know that you can't kill me. Not here, not now." He said, walking out under the moon light. "But maybe you don't need to kill yourself over me. All your life you wanted a name for yourself, right?" 
"How did you--" He stood right in front of you, his eyes looking down at you. "I have eyes everywhere, would you like to be one?" You thought to yourself. You hated demons, why would you want to be one? "No matter what you say, no isn't an answer." You felt the gross warmthon the back of your neck, and in that moment your world changed. You became what you swore to kill, but now, you'd have a name for yourself--purpose. 
"Come my pretty," He spoke, holding you back your neck. "Be my servant."

You don’t remember how long it has been since you've been a demon, a loyal one, under Muzan you felt alive than you ever had as a human. But nowadays, Muzan has been doing him own stuff without your need. You had been withdrawing back to those thoughts after your old friends left you. Your purpose seemed to be fading, and you were afraid, you shouldn't be afraid. You were grateful for heading to you the day you wanted to end it up, you took it upon yourself to do his order with nothing by loyalty and obedience--he found it amusing. 
Now after so long, you bow before him, he called for you. A meeting had commence, but you were else where. Your mind running for miles, adoring him, hating yourself, back and forth, back and forth. . 
"Gah!" You felt his hand around your neck, squeezing, everyone around you was dead at his feet. You saw him eyeing you, there wasn't hatred, but confusion. 
"You." He began. "I never wanted to admit it. I couldn't admit it." He dropped you. "But all I could hear is your self-deprecating voice in my head mixed with such loving. . . words."
You gasped, inaudible to him. You forgot. "Don't act surprise. I'm not going to kill you, heh, you'd be such a lovely toy with a precious ring to keep beside me. How about it, Y/N?" 
You nodded. "Then get on your feet. There is no time to wait, let's devor this world together." 
A purpose, a name, a reason is what you wanted. You never expected to fall for evil, but it wouldn't matter, you are evil now--not way you're going back.
