The story is similar with there being creatures that attack humans and a group of people able to fight the creatures with supernatural abilities and both series are set in a fictional European setting.
In the case of DGM, Exorcists use their Innocence to fight Akuma and the Millenium Earl while in Goulart Knights the Goulart Knights use their spirit and Holy Grail to fight the Archon.
