"What do you want?"
Belial gradually calmed down. The reason for His anger was naturally because Marvin broke the covenant, but if Marvin broke the covenant because He had not fulfilled it...
As the Covenant Ancient God, He would certainly think of repairing the covenant.
Now that He knew the root of the problem wasn't Him, Belial was no longer upset.
"First, you cannot harm my parents. You must send them back safely and unharmed."
"No problem."
Belial readily agreed. Marvin's parents were trivial in His eyes, and Marvin himself wasn't particularly important either. As long as He could get this troublemaker to leave quickly, anything was negotiable.
"Second, you cannot interfere with my freedom. I want to return to the Church of Truth."
"That's fine too, but right now you're just a soul, and this body belongs to me."
