Your's POV:
I was at Master Kagaya's home as I was sitting in front of you. Even, his two daughters one next to him too.

"Master Kagaya..? Is there something you want to tell me??" I asked him as Master Kagaya nodded at me. "Yes, Y/N. I want to talk to you about... your home at hidden Leaf Village of Konoha" Master Kagaya said as I feel something was wrong.

"Yeah... what's the matter??" I asked him as he looked down the floor. "I'm sorry to say this... there's no other way to get you back home. We don't know about your home. Also, we already know you're not from around here too" Master Kagaya said as I was horrified to hear this.

"I'm really sorry... I'm sorry, we can't take you back home to the hidden Leaf Village of Konoha" Master Kagaya as I was looking down to the floor until I leave his home.

I was all alone in the forest as I was crying my eyes out because I'm stuck here for good. And, I can't get back to my friends and family too.

"I'll never see my family and friends again..." I said as I punched the tree and I end up destroying it too. "I hope... everyone will be okay. Even... enjoying the future without me too" I said as I was about to go back to the butterfly estate until I hear a big explosion.

"What the hell?! What's going on?!" I said as I went towards the explosion until... I saw so many demon slayers were dead. Even, I saw my friends were injured too. "What happened here?!" I asked myself until I saw a demon, who had tentacles coming out from his back.

he was about to attack everyone until he saw me standing there as I was horrified what he did to everyone in the demon slayer corps.

"Wait. It's you. You're the girl, who killed my Upper Moon 4 demon" he said as I glared at him in anger. "So? Who are you, then?" I asked as he answered me.

"I'm, Muzan Kibutsuji. And, you must be Y/N Hyugo. From, the hidden Leaf Village of Konoha. Akaza, tell me everything about you. He should have killed you from the beginning" Muzan said as I saw the others were getting ready to attack him. "I'll never forgive you, Muzan" I said as I activate my chakra and, everyone were shocked of, how much power I had.

"This means war! I'll end you here, Muzan Kibutsuji! Even if, I get killed by you! I'm going to dragging you with me!" I said as I punched Muzan to the ground with so much force.

Muzan coughed up blood as he tried to attack me but, I blocked his attack with my chakra. I saw the fear in his eyes as he now knows, he messed up.
