The Gray Demons (灰色の魔神, Haiiro no Majin) (alternatively, the ashen-gray demons (アッシュ, Asshu)) are a class of demons, stated to be a higher being than the Red Demon. The corpse of a demon was used in Hendrickson's experiments. At some point of time, a Gray Demon was killed by an unknown individual of great power as it is shown to have died from a large slash wound in the chest. It is shown to have participated in a war between its Clan and the Four Races.
A few years prior to the events of the Kingdom Infiltration arc, its corpse was discovered by Great Holy Knight Hendrickson who studied the Demon's genealogy and biology and conducted countless experiments on its remains.
