Serena's POV:
I watched Genya started to fight the Upper Moon 5, Gyokko. That demon looked really strong even, he's faster too. I hope Tanjiro & Muichiro are okay. We need them, right now!

"I'm really surprised your with the demon slayer. Even, can smell demons on you. You are consuming the other demons to get a lot of power too" Gyokko said to Genya as I got really confused. What is that demon talking about? Genya is not demon! But... they know something, I don't know.

"Genya..? What they talking about?! A-Are you hiding?!" I asked as Genya got... scared? Why??? He doesn't wanted me to know..? "Oh? She doesn't know, what you are?" Gyokko said as he laughed evilly at Genya.

"That be a shame if, she finds ou-" Gyokko was cut out as he got attack by someone. When we both looked, it was Tanjiro & Muichiro. They were okay! I was so happy of this until three people were here with them too? "Serena! Are you okay?!" Tanjiro asked in worried tone as he came next to me.

"I'm okay, Tanjiro! But, we need to stop that demon! He's going to hurt the people!" I said as Tanjiro, Genya & Muichiro nodded at me and they turned to Gyokko. "I'll just kill you all! He will be really happy for, what I did! You demon slayers will never going to live!" Gyokko said as he started to attack them as they quickly dodges his attack.

"Breath of the Moon Sixth Form: Moon Ninja Attack!" I said as I used the Sixth Form and, I run towards him until I attack him.

I only mange to cut both of Gyokko's arms off but, he quickly regenerate his arms. I almost got him but, he was too fast. I really need my friends here, right now. So, we can defeat this Upper Moon 5.

"Your actually good at your sword, Serena. But, I'm getting really angry here. Just come with me if, you do that. I'll spare your friends and, let them live" Gyokko said to me as the others got worried of this. "Don't do it, Serena! We don't want to lose you! If Muzan Kibutsuji gets you! I will never forgive myself!" Genya said as he was really scared for my safety.

"I'll never come with you! I don't know, what Muzan wants with me! But, I'll never let him hurt everyone! I'll stay and, fight to protect the people from the demons, like you!" I said to him in anger as Tanjiro, Genya & Muichiro were shocked of until Gyokko grow in annoyance. "So... you like the hard way, huh?" Gyokko said until he started to attacking me. I freaked out as I dodged his attack a lot.

"Where's Mitsuri?!!! We need her more, then ever!!!" I said to myself as I started to run away from Gyokko. He then started to chase me too. "Why are you running?!! Your being a coward!" Gyokko said as I scream in fear. Why did I do something stupid?! I regret everything!!! Then there was a mist as Gyokko was confused until Muichiro came out of nowhere and slice Gyokko's head off too.

"Wow... Muichiro did it... WE WIN!!!" I said happily as I hugged Tanjiro, Genya & Muichiro until Nezuko came out of her box. "Hey, Nezuko! We win! We finally defeat the Upper Moon 5!!!" I said to her as I stop hugging them. Then Nezuko grow as I got got worried of her.

"Um... Nezuko? What's wrong?" I asked her as she was looking at something. Even, It's was behind me too. When I turned around until I saw another demon as he was really scared.

"Y-Your... the Neo Queen Serenity... O-Our Master wants us to... bring you alive to him..." he said as I was still looking at him. Even, the others were confused of this demon. I... have a bad feeling about this.
