"The world is, was, will always be filled with good and evil, because good and evil is the yin and yang of the human condition." Demons. Yeah, everyone's heard of them. Both Rin and Yukio Okumura are the sons of Satan and being around around them is basically just asking to be involved in some supernatural situation. The new girl at True Cross Academy doesn't really care about that since...she was in a pretty weird situation for a long time... But what'll happen when her situation goes from weird to chaotic? (This has some biblical verses in it. I mean, Blue Exorcist is kinda religious so...yeah.) (Also, updates may be slow sometimes...)
