Tropes for Realms of Alerfa: The Devil and the Battle Maiden story arc:

Yin and Yang (book one):

Action Girl (All the Valkyries and female battle angels in general)

Affably Evil (Doll Grethe. She may be an axe crazy blood knight, but she is willing to help out her friends and loved ones in need.)

Battle Couple (Mist and Amirani, Halja/Hel and Bullar)

Bifauxnen (Doll Grethe looks very androgynous, but is really female)

Bishounen (Loki Hrimthrung, though he is actually a hermaphrodite/intersexual)

Blue and Orange Morality (Each culture of each non-human or divine situation have their own class of morality, and their own rules of what's right and wrong, acceptable and taboo. Not all non-human or divine cultures are a like)

Cute Monster Girl (Just about every non-human female in this story arc)

Dark Action Girl (Queen Halja/Hel, Lilith Belmonte)

Dark is Not Evil/Dark is Evil (Played with and Zigzagged)

Face Heel Turn (Loki Hrimthrung used to be a harmless trickster, until he became Surtr's puppet)

Fantasy Kitchen Sink (There is a Mermaid world, a Dragon and Phoenix world, a Faerie world, a Mystic world, a "Beast man" world, let's not forget a Light and Dark world, amongst others.)

Good is Not Nice (The good guys try to be nice, but there is only so much bull shit they could take until they snap and become nasty to their tormentors)

Happily Adopted (Queen Halja. In fact, she despises her biological mother and father for abandoning her in Helheim when she was just a baby.)

Happily Married (Queen Halja and King Bullar, Mist and Amirani, Nana and Balder)

Iron Woobie (Mist Elmbarn. She goes through horrific ordeals, her father and siblings died before she was born and her mother was banished to Helheim for crimes and sins she did not commit. But Mist still tries to be as hopeful and optimistic, no matter how horrible the situation she's placed in.)

Jerkass Gods (Odinn, Loki and the gods that wrongfully accused Mist's mother of sins she didn't commit.)

Jerkass Woobie (Loki...he used to be a decent deity, but then, he lets himself be Surtr's puppet out of jealousy of the other gods. But still, despite being a jerk ass, Loki has it rough too.)

Light is Not Good/Light is Good (Played with and Zigzagged)

Male Demon, Female Angel (Amirani and Mist)

Nightmare Fetishist (Freyja Vanadies comes off as this)

Nightmare Fuel (The Flashback chapters, Noelle running into someone's pet man eating tiger. Doll
Grethe's fate, and hell, Ragnarok in general.)

Our Angels are Different (Wait! What? Were you expecting Michael Landon or Roma Downey like angels? As if! They maybe light elementals, but they don't taste anything like diabetes.)

Our Demons are Different (Hieronymus Bosch and Jan Mandijn demons anyone?)

Take That (To vampire romance in general.)

Tearjerker (All the flashback chapters in general. Even I had a hard time writing them.)

Twist in the End (Without spoiling anything, it's actually going to be very cute and funny.)

Ugly Guy, Hot Wife (Played with. The cute monster girl wives are voluntary shape shifters after all. Their default form maybe attractive, but remember, they can become Eldrich Abomination whenever they are provoked, enraged or threatened.)

Well Intentioned Extremist (Odinn and Frigga)
