Nobody's POV:
Tamayo & Yushiro were watching this as they feel really sorry for them. Yushiro was about to get Tamayo's attention until he saw her still looking at Tanjiro for some reason. This made Yushiro get really worried for her.

"Lady Tamayo..? What's the matter?" Yushiro asked as Tamayo was still looking at Tanjiro until her eyes widen in shock & fear at the same time. "No... Muzan... you monster!!!" Tamayo said as she was angry even more. Yushiro never see her so angry before.

"Tamayo?! What happened?!" Yushiro asked as he was confused still. "Muzan turn Tanjiro into a demon! He gave all of his blood to him now!" Tamayo said as Yushiro was terrified of this. He was about to warn the others but, he was too late. Tanjiro open his eyes to reveal red eyes, just like Muzan. Tanjiro regenerate so fast, this made all of the demon slayers & Hashiras in shock. "Get away from him!!!" Giyu said as he saved one of the kakushi in time before, Tanjiro can kill them.

"No... this can't be happening..!" Sanemi said as he was still looking at Tanjiro even, he saw Tanjiro's evil smile too.

Then Tanjiro saw the Sun is up and, he started to burn too. Tanjiro tried to head for shelter but, Kyojuro pinned him down to the down as he was using his strength so Tanjiro will burn and turn to ashes too.

"Kyojuro! Get away from him! Your going to get killed by him!" Tengen said as Kyojuro was still holding him until Tanjiro regenerate as he dosen't have the Sun burn anymore. He knocked Kyojuro away from him until he hit against the wall. "Oh, no... Tanjiro is able to walk in sunlight..." Tamayo said as Yushiro was shock even more.

"How are we going to stop him?! He's unstoppable now!" Sanemi said as everyone was scared. Tanjiro was about to attack Obanai until Nezuko run up to him and, hugged him tightly as Tanjiro bite down on her shoulder. "Tanjiro! Please, don't became like this! Do you remember me..? It's me... your sister, Nezuko! Please, come back to us!" Nezuko said as Tanjiro scream so loud. This made everyone cover their ears.

"Tanjiro! Don't hurt her! She's your sister!" Zenitsu said as they saw Tanjiro was going to blast them. They quickly dodges the blast, it destroy part of the city. "Tanjiro! Please, stop! This is not you!" Nezuko said to her brother as she was still hugging him still. Tanjiro was about to attack again until, he hear someone's voice.

"Tanjiro... Please, stop this" Tanjiro looked up to see the person until... he see Serena standing there in front of him. Everyone saw Tanjiro stop attacking as they looked at him, they were confuse of, what is he looking at. Everyone didn't see Serena, only Tanjiro can some reason. "What did you became, Tanjiro..? Is this, what you wanted..?" Serena asked as she put her hands on his cheek. Tanjiro wants to say something until Kanao came behind Tanjiro as he saw her. He tried to attack her but, Serena hold his arm from hurting Kanao.

"Tanjiro! Don't hurt your friends! Muzan did this you! Come back Tanjiro!" Serena said as tears falls from her eyes. Kanao dodges Tanjiro's attack and, she manage hit him with the antidote as she falls to the floor. "Kanao!!!" Shinobu said as in fear as she run towards her little sister to check on her. When Tanjiro got hit by antidote, he was knock out as he heard Kanao saying, 'Come back home' to him.

Tanjiro's POV:
I was lying down on flesh as I was doing nothing. I can't back because... Serena is not there anymore. Nothing is not worth it too.

"Serena... I'm really sorry, I didn't save you in time... I wish... can see you again" Tanjiro said as I was about to close my eyes until I felt someone holding my hand. I open eyes to meet blue eyes. It was Serena even, she had wings too.

"Tanjiro... Your not going to leave them" Serena said as she started to pull me from Muzan's hold. "Why are you here?! That's impossible!!!" Muzan said in shocked of Serena as he was still holding onto me tight but, I saw Serena gave him a warm smile.

"There's always hope, Muzan. You were defeated by them so it's over now" Serena said as she was still hold onto me even, still pulling me up with her too. "Hold on, Tanjiro!! Wait a minute, please!! Just inherit my will and feelings here!!" Muzan said as his hold became tight on me.

"You're the only one who can do it! Don't you know that you were chosen by a god to carry this out!? You can do it!! You can become a perfect... a supreme being!!" Muzan said to me as I was not listening to him. "You can't make him, Muzan. He dosen't want to hurt his firends even, he wants to go back home too" Serena said as she pulled me until I was out of Muzan hold.

"This is goodbye, Muzan... I hope you learn your lesson on, what you done" Serena said as she flys up with me in her hold. "NOOO!!! DON'T LEAVE ME HERE ALONE!!! NOOO!!!" Muzan said as we are far away from him. Then I saw wisteria above us until Serena stopped here. "Serena..? What's the matter? We can go home" I said as I looked at her. Serena looked at me as she was sad too.

"Tanjiro... I can't go with you" Serena said as I got worried now. "W-What... Why..?" I asked her as I saw tears fall from her eyes.

"This is not my home, Tanjiro. I live somewhere else... My firends & my family are waiting for me to come back home" Serena said as she looks up at the wisteria until I saw a hands come out. It belongs to my sister, Nezuko. Then she hold my hand as I saw more hands came out from the wisteria. "Serena..! Just come home with me! We can have fun even, we cane be like a family too!" I said as I didn't let go of Serena's hand.

"Tanjiro... you know, I can't come back with you. I'm dead now so that mean, I can go home now" Serena said as she smiled at me even, tears were still falling from her eyes too. "Serena! Please, don't leave! I can't do it!" I said as tears started to form in my eyes even, I was not letting her go too.

"Tanjiro. Thank you so much for help me. Even, the others too. Also, tell everyone... I said, goodbye too" Serena said as she let's go of my hand even, I was being pulled away from Serena too. "NO!!! SERENA!!!" I said as I cryed for her to come back until everything went to darkness.
