Another exorcism black article, but this one is obviously purely BL.
When Allen appears, he becomes the exorcist marshal transformed into Noah. As for how to transform into Noah and become a marshal, the article will explain one by one.
There will be original characters, but they will not be the protagonists.
Blood clan, demon clan, etc. Will all appear one after another.
It may be a tragedy later on, because there is no comedy, but this is just my initial setting. As the story progresses, it may turn into a comedy.
