Madness

Madness by Shinmotsuki Kairi I think was one of my first yoai mangas. It was sometimes confusing and at first I didn't know Izaya was a man lol but it was good all the same. This story only has two books to it, which for manga is really short, but I liked it anyway ^^

Genre: Action, Adventure, Comedy, Fantasy, Romance, Shounen Ai, Supernatural, and Yaoi.

Summary: 

It is the year 3000 AD and Airishuu Izaya Luke is a Catholic priest of the Cult of Saint Ruka. He was charged with watching over Kyou, the leader of a group of murderers called Madness. Kyou has spent the past 3 years imprisoned in Izaya's church, with no memory of his murderous nature. Kyou's life has become a tranquil one until the day the church is attacked by an old enemy, Sae, a former member of Madness, who is attempting to take Kyou's demon sword Jigfreed. Kyou's murderous nature is awakened and he proceeds to kill Sae. He then goes to keep on killing, but Izaya stops him. As it turns out, Izaya is a Suppressor, someone who can stop Kyou when he snaps and goes crazy. Kyou forcefully takes Izaya with him to be his Suppressor and so begins there journey...

I would consider this manga for mature readers only
