Mikael is a puzzling character in the beginning of I'm Gonna Be An Angel. In the beginning of the anime, it is apparent that he shares an intangible relation with Noelle, even to the extent in which he is capable of speaking to her through telepathy. He encourages her to become an angel. He carries the Book of Chaos, in which the text fills a single page for each instance in which Noelle accomplishes an angelic deed. He is very strange in each episode for reason and it seems reason the other side where boys go at it. He seem to be in a romantic relationship with Raphael.
