Twin Star Exorcists in English. Rokuro Enmado is a boy who abandoned his dreams of being an exorcist. A terrible tragedy happened during his childhood that left his friends dead and him the only survivor. One day he has a fateful encounter with a girl named Benio Adashino who happens to be a well known exorcist from the east. Some stuff happens and they become rivals and are super competitive with each other. But their rivalry gets a twist when they get the title "twin- star exorcists." The duty of the twin stars is to marry and birth the ultimate spiritual warrior. (the Miko) Too bad they pretty much hate each other lol
There is an anime adaptation it just came out this year in April 2016. I haven't watched it yet. But I'm current with the manga. Check it out when you have a chance!
