Puck immediately came out of his flashback as he saw Rael in his battle stance.
When he had met Rael, he was in one of his debauchery stages he would go through whenever he was sad, which would last for hundreds of years.
After Puck was adopted by him, Rael's interest shifted and his time started to get invested in him instead.
Rael's expression remained completely calm, and his posture was that of someone confident in their victory. He had taken notice of Puck's bizarre reaction when he released his aura but didn't pay any mind to it.
Flames burned high in the sky as his faith sword descended… it was a straightforward attack without any flourish or profound skill yet it held all of the power in Rael's body.
The oppressive power of the attack was so large that it seemed like there was a mountain crashing down from the sky.
