Gun Devil

The Gun Devil is a very powerful devil. It first appeared in the US 13 years before the start of the series. It gained its great power since a lot of guns were being bought as a countermeasure for devils, this lead to an increase in gun crimes and civil revolts. The Gun Devil first appeared the same day as a terrorist attack was made in America using guns. Within about five minutes the Gun Devil almost killed 1.2 million people and disappeared. This incident lead to an increase in fear of devils, thus leading to all devils gaining power. Because of this, the Gun Devil is a big target for most devil hunters. Makima promised Denji that she will grant him any one wish if he kills the Gun Devil.
