Adaptation Displacement: While Orphen admittedly isn't as popular as most shows are today, very few people who are fans of the show to at least some extent even realize that this began as a light novel series.
Die for Our Ship: How dares Cleao get in the way of Orphen and (insert: Majic, Hartia, Azalie)! However, at least in the novels she eventually does get him, as the new series revealed.
Evil Is Sexy: After Azalie takes control of Childman's body, we start having more glimpses of his well-toned, tan-skinned frame.
Ho Yay: Orphen has this with Majik and Hartia. On one hand, Majik adores his "Master" and sticks by him no matter what; on the other, Hartia's own devotion to Orphen is very easy to see as him being the series's Unlucky Childhood Friend.
Seasonal Rot: Revenge suffers from decay of all kinds, and not because it's Lighter and Softer. Though it goes better towards the end, according to some.
Values Resonance: The deal with Stephanie being a trans sexual person isn't handled for cheap and offensive laughs. When Orphen explains how she went from the male-bodied Stephan to the female-bodied Stephanie, he does it in a matter-of-fact way and doesn't think less of her for it, and later we're not supposed to side with Cleao when she makes a careless comment about it. Not to mention Stephanie herself is portrayed as a normal and kind person.
