I am slaying gods in a psychiatric hospital.

Have you ever thought that beneath the dazzling neon lights of the urban sprawl, there are lurking monsters from ancient myths? Have you ever wondered if, above the moon that hangs high above the heads of mortals, there stand gods watching over the human realm? Have you ever considered that amidst the bustling crowds of the modern city, there exist extraordinary individuals walking among us, taking on the roles of gods? In a society dominated by humans, countless anomalies lie hidden; in those neglected realms of life, ancient gods dwell. Archangel Michael, Hades the Lord of the Underworld, Poseidon the Sea God... But where have the gods of the Great Xia disappeared to? In this world belonging to "humans," the "mysteries" need to be eradicated!
