"Child, I am useless, knowing my abilities are limited. Even if I had three lifetimes, I could never fully repay them. So I have decided to return to the Clan of Darkness. Child, I know you, like me, hold some grudges against the Clan of Darkness, but you definitely do not hate them,"
"Before you died, you always worried about the clan, hoping I could help them if I could. After all, we are father and son; I am your son. No matter what you ask of me, there would never be a hint of refusal, so why use the word 'please' in the first place?"
"Therefore, I have decided to repay your kindness to the Clan of Darkness. I will first return to the clan and should the Clan of Darkness face difficulties, I will certainly help as much as I can. At that moment, it could be considered repaying about a tenth of your kindness,"
"As for future repayment, if I have the chance to be your son again in the next life, I will repay you slowly..."
