Your's POV:
I saw Urogi pulled out my Kunai as he looked at it until he broke the silence between us.

"Your a shinobi? Are you??" Urogi said as I looked at him. "Yes... what happened here with shinobi..?" I asked him as Urogi let's go of my Kunai.

"Shinobi went extinct by the Edi Period. I didn't know they still exist" Urogi said as I was shocked to hear. "Oh, shut up! She's not the only one, Who still exist!" Sanemi said as I turned to him in confusion.

"Tengen Uzui & his wives are shinobi too! They still exist here!" Sanemi said as he was giving them a crazy smile. I feel really happy, what he said. "Shut up, you Hashira. At least one of you will die soon"

"What did you say..?" I asked them as I quickly attack Karaku. He was caught of surprise until I tackled him to the ground and, I put my Kunai near his neck as I was glaring at him too. "What are you, guys talking about?! Which Hashira is going to die?!" I screamed at him as he just smiled at me.

"Okay. If you really want to know" Karaku said as I was putting my Kunai closer to his neck. "Akaza is going to Mugen Train because a Hashira is there, on their Mission to protect those innocent humans" Karaku said as Sanemi's eyes widen in realisation.

"That's where... Kyojuro is. Even, the other demon slayers too" Sanemi said as fear took over me. Akaza is going to kill Kyojuro! "Calm down, Y/N... remember what to do, what is something bad happened..." I said to myself as I took a deep breath and let it all out. I then activate my Byakugan again, as I was looking around me until I found fifth demon, who is hiding in fear.

"I found you, demon!!" I said as I threw my Kunai at them until they screamed in fear as they quickly dodged my weapon.

"What the?!" "Sanemi! That's the real demon, we have to kill! Those demons are clones! You hold them off until I killed that demon!" I said to him as Sanemi nodded at me until he begins to attack Urogi, Karaku, Sekido & Aizetsu.

"Where that demon go?!" I asked myself until I found him running away from me. "You can't get away from your death!!" I said to them as I pulled out my Kusarigama.

"This ends now!!" I said as I managed to cut his head off.

He screams in pain as his head fly off from his body. I saw his body slowly turning to ashes as Urogi, Karaku, Sekido & Aizetsu slowly disappearing too.

"You did, Y/N! You killed Upper Moon 4!" Sanemi said as he gave me a crazy smile. "There's no time for that! I need to go save Kyojuro! Before, he gets killed by Akaza!" I said as Sanemi nodded at me until I saw a crow landed on his shoulder.

"Follow my crow. They can lead you to the Mugen Train" Sanemi said as the crow start fly and, I followed them. "I'll bring back up too! Be careful, Y/N!" Sanemi said as he went to a different direction to get back up. I just hope, I'm not too late!
