Ga-Rei: Zero, Tokyo ESP Recommendations
The animation style is the same if not identical
Some of the characters in Ga rei zero are in tokyo ESP and vice versa
The two animes take place in the same world at roughly the same time
There is a lot of violence in both along with the depressing themes that you would see in Ga rei zero
Overall these two anime feel very similar so if you like on you would also like the other.
