Haruhi, Yuki, Mikuru, Koizumi, and Kyon's Younger "Sister" (Brother, actually), are all the same person. They were all based off of me. So, they're all Satan (The One True God).
That's my ps2 in the third image, of Kyon and Satan.
5th image, final image, is a statue of me in a church dedicated to me, to Satan, a statue of Satan.
All churches and religions are actually mine, since I'm The One True God.
