Serena's POV:
"Wait a minute... why is Kokushibou's body still there..?" Genya asked as we all looked at the body. His body was still standing until something happen. Kokushibou was regenerating fast until he became something horrifying.

I started to freak out as I saw Sanemi, Genya, Muichiro & Gyomei fight him. Then Kokushibou looked at me as I got really scared until he tried to attack me but Sanemi saved me as he was glaring at him.

"Serena! Get out of here! We can take care of him!" Sanemi said as he went to attack him again. Wait... is he... in pain..? He must be suffering from something or... feeling guilty too. Then Kokushibou knocked both Genya & Muichiro away until he came towards me. "SERENA!!! GET AWAY!!! RUN!!!" Gyomei said as he was tell me to move but... I refused. I let go of my sword as I waited for him until Kokushibou bite down on my shoulder as blood came out of me.

"SERENA!!!" Muichiro shouted as he was about to attack him until Sanemi, Genya, Muichiro & Gyomei saw me hugging Kokushibou as they were shocked of my action.

(This is, how Serena is hugging Kokushibou, right now!)

Kokushibou was shocked & confused of me as I gave him a sad smile even, tears were coming out from my eyes too.

"Is this, what you wanted... Kokushibou? You wanted to fight for ever..?" I asked as I was still hugging him tightly even, I didn't let go of him too. "W-What made you become this... Is it hatred..? Or, is it something... you wanted for along time..." I said as Kokushibou slowly loosen his grip on me.

"I wish... I can help you... & the others, what you gone through. I'm so... sorry for you.." I said as I saw him turning into ashes. Tears finally fall from my eyes as I looked at him in sadness. "I... hope you go to a... better place. Goodbye... Kokushibou" I said as he was finally gone from my arms.

"Serena! Are you okay?! Your badly injured!" Genya said as I was really worried of me. Sanemi, Muichiro & Gyomei were about to come & check on me until I stand up from the floor. "Sanemi... Genya... Muichiro... Gyomei... This is the finally battle against Muzan." I said as

I turned around to them.

"Even... This is going to be my last finally life too" I said as I smile at them. They got confused of me as both Genya & Muichiro were very worried of me too. "Serena... What are you talking about..? Even, what did you mean your finally life too..?" Muichiro asked as Sanemi saw me rising my sword high up.

"Serena?! What are you doing?!" Sanemi asked as he got really confused. "Go & get the other Hashiras... You need to work together to defeat Muzan for good... So, this is goodbye guys.." And with that, I quickly destroy one of the pillars even, blocked their path to get to me too.

"Serena! What are you doing?! You need to stop this, what your doing!" Gyomei said in a worried tone from the other side of the wall. I turned around as I started walk away from them even, they were still call me. "I hope you are hungry... because I'm your lunch tonight, Muzan" I said as I run towards his location.
