With a silver wig and a pair of horns bought from a street stall for fifteen yuan, a new Demon King rose to power in the demon realm.

After dyeing his hair a blinding gold and putting in emerald-green contact lenses, the legendary saint, said to radiate holy light, appeared among the common folk. Even the pope gave his approval.
