The first person that entered Keon's blurry vision was someone he was familiar with. It was the masked man he met in the past that called him as Master
At that time, Gabe and Mady were still not sure about his identity but when that masked man met Keon and they fought, he was forced to use his Avatar of Death. Only then did they confirm that Keon is their Master
Despite seeing a person that he knew would help him, Keon didn't even move an inch. His eyes were still completely lifeless as if he had given up already
The masked man saw Keon's current state and his eyes flashed with pity. He walks towards Keon's tortured body and kneeled in front of him
