The Battle Maiden and the Town of Lewd Fairies

Odin's subordinates, the valkyries Sigrun and Brynhildr.
While training with the einherjar, the evil god Loki suddenly appeared before them.
To achieve his goal of "turning the gods into fairies," Loki's first step
was to make use of these "half-god, half-human" valkyries,
so he overpowered them with overwhelming force and carried them off somewhere.
Loki brought the two to a remote borderland in the world of the dark fairies, far from the realm of the gods,
where he used the magic handed down in the "Town of Lewd Fairies"
—the "magic that turns humans into fairies"—on the two half-god, half-human valkyries.
The two valkyries fought desperately against the fairy-transforming magic,
but the power of "Primordial Chaos," which possesses the power to distort the world and was implanted along with the spell, was also at work, and in the end the fairy-transforming magic took full effect.
Half of each of their bodies changed from "half-human" into "half-lewd fairy."
Just as Loki's claws reached further toward them,
Odin's familiar appeared, drove Loki back, and rescued the two.
However, as twisted beings that were now half-god and half-fairy, they had no right to return to the realm of the gods,
and the two were forced to "return to being half-god, half-human" by their own power.
To achieve this, they head to the nearby "Town of Lewd Fairies,"
aiming for the "magic that turns fairies back into humans" they learned there,
and begin collecting the "seven magic crystals" needed to cast the spell.
But they discover that to obtain the magic crystals,
they must "generate strong emotions through various experiences" in the "Town of Lewd Fairies."
Will the two former valkyries manage to keep their sense of self through the experiences in this "town of lust,"
successfully cast the magic, and return to their positions as "valkyries"...?
Or will they be swallowed by chaos and fall completely into becoming "lewd fairies"...?
What does fate hold for them?!!
