Naoi is God.
He controls it, he is president, he can maintain this world, how it works, and he can do it alone.
There is a need for Naoi, such a yearning need that the various NPCs call out his name, begging for him to be their leader. They plead and beg and he hurtsthem.
He makes sure they won't whine, because whining is annoying and stupid andimperfect and it doesn't need to be in his world.
That's how he maintains his position as God. He shows his subjects the good and the bad - if you are imperfect, you will most certainly be punished.
And that's how it goes.
You don't deserve to be in his world? Well he'll show you how much you don't belong - and if you don't fix it, he'll make sure you're out.
He doesn't want stupid, imperfections in the mirror making it completely blurry.
Because he is God.
And he sees your thoughts, your actions, your life, because he is in control. They all fall down, almost in a bowing motion, making him their full-fledged leader.
Naoi Ayato is finally needed. He is finally a person. Finally needed to be himself to keep something in balance.

Keima smirks as the next girl succumbs to his obvious charms, the screen glaring off his glasses.
It's just a matter of time, really. One day, they'll all fall down, fall in love and he will be the leader - the God of the harem of angels.
Their hair that falls just perfectly, their eyes that meet his, their blush that captures their cheeks - just all for him, for God, for the 'Divine One.'
No one can run, no one can hide, because all the girls are his, will be. It's not that hard to comprehend - in fact it's so simple, that even the stupidest girls would get it.
They all love him.
He is God, they all fall down to his charms.
Simple.
