Phantom in the Twilight

In both the shows, our MC finds herself in the unexpected company of extremely stunning supernatural creatures. Both have her at the center of activities that have been happening for at least a century, and both these girls possess a lot of spunk. This is more true for the MC of Phantom, who has to often be physically restrained to stop her from wanting to save her friend. 

The same reverse harem where it has lone girl with special powers and the guys with each his own speciality.  

The same plot where it involves people who specialize in dealing with the supernatural.

The same plot where girl has special abilities and le harem members her group of male harem member aiding her.  

both are centered around female mcs and alot of action as well as nice art and character designs too. 

These two anime contain mythical creatures, Phantom in the Twilight calls them the Umbra, while Mahoutsukai no Yome has no specific name, since they are from different species. Umbra exists from the creation of human's mind. The others already exists and living hidden among the humans. So if you are looking for more anime that contains these kind, well you are looking for the right place, just expect it to be less romantic and definitely no harem for Mahoutsukai. Also barely fighting scenes, but beautiful animation. 

Romance, vampire(s), and a secret government trying to control the relationships between humans and non-humans. While Devils Line is more focused on romance, and Phantom in the Twilight is more like a group of friends battling side-by-side. Both anime have a refreshing kind of humor, and can handle their darker moments quite well. Not to mention that they each have MC girls that are not completely useless, which is definitely a plus! 

fantasy, a lot of guys protecting the mc, and a vulnerable mc
