"Boss, what are your intentions towards me?"
Since Realius had told him that he could ask about that, Deus did just that.
"I want to recruit you to become my subordinate, officially. Not as your boss in Real Delusion but towards me, Realius Regulus."
Realius offered to recruit Deus to become his subordinate, instead of just being the subordinate of the Real Delusion organization.
"You should be aware that it is difficult for a system user like you to survive long in the vast multiverse when your system isn't battle oriented. I can offer to protect you until you become strong enough to fend for yourself but at the price of you becoming my subordinate and listening to my orders."
"You don't have to worry as I won't treat you miserably. I have always treated my subordinates with lots of benefits in exchange for them listening to my commands. As long as you perform well as my subordinate, I won't treat you poorly."
