"Look who is awake while my son has closed his eyes forever!"
His voice was filled with hatred as he spoke.
Just looking at the man, you could tell that he was not there to congratulate Zero on his recovery. Contrary to that, the man seemed to be very hostile to Zero.
It was not just him but other people who had the same expression. The looks on their faces indicate they were ready to attack Zero at any moment, but may have refrained due to Zero's parents being present. In terms of power, those people fell quite short compared to Zero's parents. Even if they attacked together, they would have been defeated by Zero's parents.
But that didn't stop them from shouting at Zero.
"Give my child back!"
"The Devil's friend!"
"You killed our child!"
…
Just listening to their words, one could guess who they were. They were the parents of Zero friends who died in the dungeon.
