Duel to the death Brother vs Sister End

Kyle narrowly dodged the lightning bolt and swung his sword towards Rose. Rose was impaled in the left leg but that didn't slow her down as she sent electricity down the sword and into Kyle. Kyle let go of his sword and started throwing punches at his sister who dodged them with ease.
"Come on Kyle, I thought this was gonna be fun!" Rose said before grabbing Kyles fist and sending more electricity into his body. This started affecting Kyle as he was now finding it difficult to stand and he fell to his knees.
"Well Kyle, it was nice knowing you." She then threw a bolt of lightning down to him and... it was deflected? A strange barrier had surrounded Kyle and was protecting him from the lightning that Rose was throwing at him.
"What is this!" Rose shouted before Kyle slowly stood up.
"You see Rose, I am an agent of the gods and goddesses; they want to see you brought to justice just as much as I do. So they have given me their power in order to destroy you!" Kyle then released a ball of light from his hand and threw it towards Rose.
"Fuck!" Was all Rose said before letting out her own ball of blue electricity and throwing it towards the ball of light coming towards her. The two balls collided and exploded sending bolts of blue and yellow light in every direction. The two siblings continued with this until they were both worn out.
They could both pull off one more move. Kyle created a sword of light and charged towards Rose whilst Rose created two daggers of electricity and charged towards Kyle. They were both impaled with each others weapons and they fell to the ground in pain. Kyles gods couldn't save him now nor could Roses power save her. The duel to the death was other and it had ended in a tie. But one person said that they could see a hand twitch with life hours after the two had fallen...
