Belial watched the boy's reaction closely, feeling satisfied by the initial apparent wariness and confusion that appeared on his face. That was the normal reaction to being presented with a situation like this, of course. That and intense fear, although it did vary from person to person. His smug smile disappeared quickly once the boy spoke however, his eye twitching slightly in irritation. Who does this damn brat think he's talking to...? Is this supposed to be some kind of bluster? Such a disagreeable child would surely make an awful master... Belial's lip curled as he wondered whether he could back out of this now, leave the brat for some other demon foolish enough to make a contract with him...but he was fairly hungry. And he had dealt with unpleasant personalities before. He couldn't let this brat force him to back off, after all. A mere human, simple prey in the face of a great demon such as himself.
"This sort of experience is arguably more dramatic than breathing your last in an alleyway surrounded by empty bottles and with a stray cat for company, but very well...I am offering you the chance to fulfil your deepest desire, child. The offer I am making you would bind me into your service, to obey you unconditionally until the day your wish has been achieved. After that I will have to take my payment, but...I believe this path would still be preferable to you compared to dying a nameless death as trash once I resume your time. So, what say you? Unless this has once again been too complicated for you to understand...shall we make a contract? As for the price for my loyalty...I suggest you do not worry about it. It cannot be taken until you are dead, after all," Belial finished, chuckling softly.
