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.
Complete Monster: Escalena from Revenge, the second season of the anime, is a sorcerous beast sealed away by the Heavenly Beings countless years ago for the havoc she wreaked upon the world. Escalena makes a bargain with a sorcerer named McGregor Nielsen when he and his daughters are at their lowest point, saving the girls from a deathly illness and resurrecting one of them in exchange for McGregor sacrificing five sorcerers to her to free her. Escalena erases the memory of McGregor's youngest daughter Lycoris and forces her big sister Esperanza to constantly edit her memory to use her as a pawn, dispersing her to lure Orphen himself into her clutches. Once she's finally outed as the mastermind behind the plot, Escalena murders Esperanza right in front of the rest of her family (and not before revealing that she was the girl who died, which Esperanza didn't know) and cruelly gloats she never intended on keeping either of McGregor's daughters alive, her true goal simply being to break from her seal and destroy the world for nothing more than her own amusement, even managing to spitefully kill McGregor himself in the throes of her own death after Orphen defeats her. By far the most evil of Orphen's usually-sympathetic enemies, Escalena is a deceitful monster, both literally and figuratively.
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.
The Scrappy: Cleao in the first season, mainly for doing almost nothing but bitch and trying to make it all about her. She switches to a Base-Breaking Character later, tho.
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.
Stoic Woobie: Childman, due to his emotional baggage and noble heart; not ever showing how it hurts him inside and how deeply he blames himself for the deal with Azalie.
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 no one's 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, and her trans sexuality is not theonly character traitshe has.
The Woobie: Fienna, for being bound to her town and the medium between people and the Dragons no matter what; and later... LYCORIS!
