I've been finding this for one year and I can't get off this on my mind, istg I thank you so much if you were able to find this manga:
* The world is in chaos because of the lurking dark monsters, people started being one and this male mc was scared for his life. Him & his Female best friend stayed on school because the Male Mc turned into the dark monster and the female bestfriend don't want to leave him alone. While he was sleeping, he killed his Female bestfriend, while in the next morning he mourned for his death and on the way to destroy every dark monster in Japan (?) being called the "Black knight"?
* A small memory only within here, I apologize. MC world was full of demons, so back in the days, people were fighting demons everyday while the Mc trains his body to fight a demon when he is older with his male (best?) friend, but recently people started making Demons as their Gods and completely forgot what they did in the younger days。The last thing I remembered is that the MC fought a demon who killed it's worshipers infront of him & blah blah blah.
