They began the battle and each one of them picked the opponent they thought they'd be able to beat the easiest. Lizzy attacked Gowther first and beat him, Meliodas attacked King, Ban Diane, Merlin Escanor. Escanor, Ban, Meliodas and Lizzy were the winners of the first round.
The next round Ban attacked Lizzy and Escanor attacked Meliodas. Lizzy and Meliodas won after about three hours worth of battle.
For the final round, they were up against each other. Lizzy laughed. "Let's go with all our power."
"What?"
"All of it." She grins.
"I don't wanna hurt you."
"You won't." She laughs.
Lizzy's Point of View~
As Meliodas stood shocked I summoned some fire. "Come and get me."
"You- How?"
"Heh. This is normal. Remember the drinking contests?"
"But you didn't pray just then."
"I don't need to." The battle went on for two days and nights before I had finally made him completely weak. I promptly knocked him out at sunrise of the third day. "That was fun." I grin. Then I see the other Sins. "Hey."
"Were you.... toying with him?" Merlin asked.
"Hm?"
"You... I sensed a lot of power coming from you in that moment when you summoned the fire. How powerful are you?"
"You got me." I smile. "I can, and have, beat the Demon King, Meliodas's father."
"What?" Their eyes go wide.
"Yeah..." I grin and flick Meliodas on the forehead. In the instant that my finger hit his forehead it was charged with enough healing power that a dead man could get up and walk. He literally jumped onto his feet.
"What the hell?"
"How?" Merlin asks softly. "Can you teach me?"
"Sure." I grin.
End Lizzy's Point of View~
"Alright!" She grins. "What now?"
"Well the world's still under attack."
"I suppose that makes sense. Let's go!"
