D.Gray-man, Sousei no Onmyouji Recommendations
Enmadou Rokuro = Allen Walker
Adashino Benio = Lenalee
-Exorcism and weird looking monsters (some of the monsters are dark skinned humans, idk why that‘s a thing lol)
-Protagonists that have some kind of demon powers
-both have many Eps
Has the whole exorcist theme fighting demons
hilarious but can get pretty serious at times
MC also believes in the "destroy all the evil" reasoning
amazing series anyways
Both anime deal with exorcism and both of the protagonists have a cursed arm which allows them to fight. The atmosphere of both series is quite dark for most shounens.
Main difference is that Sousei's protagonist is more hot-headed than D.gray-man's.
