Hellsing Ultimate
Anime Like Attack on Titan
There are anime about the occult, and then there’s Hellsing Ultimate. Set in an alternate history London where a faction of the government is devoted to hunting down and eliminating vampires, the world finds itself on the brink of destruction when vampiric Nazi rise up to kill, maim and slaughter everyone they can. The only one who can stop them is Alucard, the dual pistol wielding lord of darkness, and his team of supernatural allies.
While it may not have as much subtlety as Attack on Titan, it does match up to it beautifully with buckets of blood and some legitimately creepy monster designs. It also boasts some great city-spanning battles with characters zipping and screaming through buildings, making for a great stand-in for vertical-maneuvering gear fights.
