Both are psychological horror movies about the cases of a supernatural detective agency. Both are partly episodic, and partly about the tragic backstory of an investigator herself.
While Garden Of Sinners as a whole is similar to Enma, GoS 5 is most similar. Both anime us the metaphor of a house which symbolizes the subconscious of people as kind demonic prison. In this environment, past and present, life and death, and reality and imagination blur into a feverish nightmare.
