586 Why does it seem so immoral?

After school.

Seiji headed over to the Juumonji mafia group's residence and explained to Hisashi about training in the Domain.

Hisashi fell silent when he learned that the demons there might be connected to Hell and influence him negatively. But, he then broke out into laughter.

"I've already been through the real Hell. Who cares about some Domain?"

"I apologize for treating you like an experimental subject." Seiji was truly apologetic.

"Kaede and I are definitely the best choices when considering that we should be more resistant against Hell's influence. And since it's an experiment, simply me going alone will be sufficient." Hisashi adjusted his eyeglasses. "This is a reasonable arrangement. I understand how it is. There's no need for you to apologize."

Seiji could only smile in response to Hisashi's smile. "I shall prepare a full set of equipment for you, and then contact you about the time for the training."
