We cut right into the story.
Diede: Oh god, This is bad so many corpses
Shiro: I CANT TAKE THIS ANYMORE! I WANT IT DEAD.
Diede: WE ALL DO
Yuri: Im holding them back! SHIRO USE METAL!
Shiro creates a ball of metal and launches it at the demons, which attacked the city.
Diede: SEWER BURST!
Diede created a tornado made out of acid that got sent to the demons but something unfortunate happens, Diede was hit by a spear but he didn't go back down as he created a bigger version of the acid tornado in the form of a tsunami
Diede: FLOODING SEWER BURST.
Yuri: Diede! Stay back you got hit. Shiro?! Where are you?!
Shiro was standing there crying looking at Yuri, as turned to him
Yuri: There you are, alright keep fighting.
Shiro: I'm sorry.
Yuri: Huh?- | Yuri's eyes widen as Shiro's head explodes and his body falls to the ground.
Yuri/Diede: SHIRO!
Diede/Yuri: ACID RAIN/SANDSTORM! | Diede shoots 10 acid bullets at the demons as Yuri attacks with a Sandstorm that absorbs the acid bullet which turns the sandstorm into ACID
Yuri: QUICKSAND | Yuri Creates Puddles of sand under the demons but it fails intensely, Diede then fell with a spear through his neck, coming out on the other side of the body. He died right here.
Yuri was alone while fighting and defending herself with tears in her eyes. Yuri did everything to defend herself but it wasn't enough, She soon collapsed to the ground from exhaustion as she then quickly got spread to pieces by the hoard of demons and soon enough the demons have taken over the city with no one left.
A Few years later. The Demons have left the city and gone back to humans living there but yes, Demons will always return somewhat.
