Nobody's POV:
Muichiro make sure to block the Upper moon's way before, he can get Serena. This got Gyokko got really annoyed but, he just smirked at the Mist Pillar.

"That was big mistake for letting her escape from me, you Hashira" Gyokko said as Muichiro started to attack him until he started to used his demon blood art.

"Blood Demon Art: Water Basin Of Hell!" Gyokko said as Muichiro was trap in a water bubble thing.

"You can struggle all you want, no one cannot escape from my blood art. I'll be looking for Serena now. I have a feeling, she found the other demon slayers" Gyokko said as he disappeared in the pot. Muichiro was terrified now.

"No... No!!! I need save Serena before he gets her!" Muichiro said to himself as he struggles to break free from the demon blood art.

Serena's POV:
I was still looking for the others until I found them, I quickly run up to them as they got worried of me. They should be really worried for Muichiro's safety.

"Serena?! What happened?! Even, why are you running??? Also, where's Muichiro too???" Tanjiro asked as Genya looked at me in concerned. "It's Muichiro! A Upper Moon Demon is here! A-And, he came for me too! Muichiro told me to tell you, guys so you can help him defeat Upper Moon 5!" I said to them as they nodded at me.

"Hey, Genya. Can you stay with Serena. We don't know if, the Upper Moon Demon will come for her" Tanjiro said to Genya in a kind tone. "Sure... Just be careful. We don't know, what the Upper Moon is capable of..." Genya said as he was not looking at Tanjiro. When Tanjiro quickly leaves us as he went to help Muichiro to defeat the Upper Moon Demon.

"Genya..? Why are you being mean to Tanjiro? You should have a good reason.." I said to him as Genya got nervous until we both heard something above us. When we both looked up... we were terrified to see. It was Upper Moon 5, Gyokko! Even, he looks so terrifying too! What the heck is he?!!

"You can't hide forever, Serena! That man will have you!" Gyokko said as I was shaking in fear until Genya pulls me closer to him even, he pulls out his nichirin sword & his gun too.

"You staying away from Serena!" Genya said in anger tone as he was ready to fight him.
