Douma's POV:
I was really confuse of Serena-chan as I slowly remembered, what Serena said to me. Even, I remember those butterfly hairclips too. The pillar I killed.

"Oh! You mean the girl, who use the flower breathing technique!" I said happily to her as I saw her expression got very angry too. "Is that the girl's name? I was really upset of, I didn't get a chance to eat her. I really want to eat her but the Sun was coming up-" I was cut off by Serena-chan as she stabbed me in my eye with her nichirin blade even, I was shocked of her action so quickly used my demon blood art but, she dodges my attack.

"She's even more faster... I didn't realise, she moved" I said to myself as I was regenerating from her attack. "I didn't realise you moved, Serena-chan. I'm very impressed of you!" I said happily as she was still glaring at me.

"I hope, I make you suffer! This is for Kanae!" Serena said as she was still pointing her sword at me. I was prepared to attack her until I feel something painful on me. It was wisteria poison?! This is amazing for the first time!

Serena's POV:
I was watching Douma cry in pain as I was still on my guard until I saw him vomit out blood as I was shocked of this.

"He got rid of the poison?! I did not expect this! So, I have to think of a way to kill him" I said to myself as Douma give me a creepy smile as he was regenerating too.

"This... is the first time you amazed me, Serena-chan! Where did you learn that from?! You made me feel something, I never felt before!" Douma said as I was standing there in confusion of him. "I learn the special technique from one of the Hashiras!" I said as I was still glaring at him.

"That's amazing, Serena-chan! You learn a lot from the pillars! Even, you used one of the pillar's skills too! Your just amazing girl, who's Queen of the Moon Kingdom!" Douma said as I started to attack him a lot.

"You're so fast, Serena! If I was you, I should keep your guard up" Douma said until something painful hit me across the chest as blood came out from me too. "He... got me..." I said as I was in a lot of pain as I fall onto my knees. This must have hurt you, Kanae.

"I wish, I can save you in time so your sister will be so happy.." I said as I was about to close my eyes until I saw Kanae in front of me. "Serena! Don't give up! If you die, right now! Everyone is going to die!" Kanae said as my eyes widen, what she said.

"No... I'm not going to give up here! I'm going to save everyone! Even, i'm going to end Muzan for good too!" I said to myself as I slowly stand up from the floor even, I was ignoring my pain too. "Wow... you're still standing. That cut is really deep, I made" Douma said as he was still shocked of me.

"I'm not going down... not just yet!" I said until I run towards him as Douma was surprise of me. He tries to hit me but I keep on dodging he's attacks until I stab him in his stomach with my sword and use my strength to push them up until I pinned Douma against the ceiling.

"I feel so tired already... from fighting him. If my friends were here... they will be proud of me or... happy because I'm protecting the innocent people from those demons..." I said as I was imagine of my friends even, they are smiling at me too.

"I... I wish you, guys were here to help me fight them..." I said as I was fall from the ceiling. When I looked back up at Douma, I saw his stupid smile even, I saw ice flower coming towards me. "Why can't that stupid man stay down..." I said to myself as those ice flower veins wrapped around me. When those ice flowers pulled me towards him until Douma wrapped his arms around me tightly, like he's giving me a hug.

"That was great! You worked so hard! I was so moved!!" Douma said as I saw him begin to cry for some reason. I slowly pulled out the wisteria poison, the one I took away from Shinobu. Then I stabbed him in his stomach until I push the wisteria poison inside of them and I broke it with my bare hands too. I quickly pulled it out so he doesn't realise, what I'm doing. "You can't stab me forever, Serena-chan! You just waste your energy!" Douma said to me as he was still crying even, smiling at the same time too.

"I never expected a weak girl like you to get this far! You hunted so many demons even thought you have less talent than the girl named, Kanae" Douma continued as I was struggling to break free from him but, he tightened his hold on me as I growled at him in anger. "It's a miracle you haven't died yet. Despite knowing everything is useless, you're still foolish enough to try and take me down. This foolishness is what the humans so fleeting, yet so wonderful" Douma said as I was trying to find a way to escape from him.

"You are now worthy of being eaten by me. Let us live together for eternity. Are there any last words you want to say? I'll listen to you" Douma said as I didn't give up yet. "Go to... HELL!" I said in anger as I dig my nails in him.
