This one is not actually on the prompt list, but I decided to post it here anyways. Consider it a bonus of sorts. In dedication to Light's narm-charm (and his ego the size of Tokyo), I made it slightly narmy.
Mirror
When Light looks at himself in the mirror, he sees the visage of an all powerful god; but not just any god. No, what he sees is the God – the all-powerful, unrelenting force of justice, beautiful and oh-so absolute. He is that God , the ruler of this new world of his, the one he has worked so hard to create. There is no one who would dare contradict that claim.
He is worshipped, as he should be. All the would-be heretics brave enough to speak out against him lay trampled at his feet as the rest all cower in fear, hiding in dark corners to avoid the power of his justice. The streets are filled with those who shout his name in support, millions of eager souls practically falling over themselves in order to please Kira.
And with L gone, there is no one left who can oppose him. He has won completely, and he has claimed this world as his prize. None will come against him, not now.
He smirks at his reflection, fingers running along the mirror as he admires himself.
"This is my world, Ryuzaki." He whispers, triumphantly, "I cannot be defeated."
As he turns away, he doesn't notice the tiny cracks that spread out and fissure against the glassy surface, becoming spider webs that distort and fracture the image of his back. He cannot see the signs of things yet to come.
