Monmusu Quest fan character, by Solan. Yup.
In another realm, the great goddess Ilias created the world and all its lands, and in her kindness created creatures to dwell within. In the end, she was able to create humans, and bestowed upon them all of her love. But before she managed to give life to her most beloved creation, there were many failures... and thus monsters entered the world. Taking shapes approximating human females, but far stronger and more lustful, monsters plague the world, preying on humans and stealing their semen and, often, their lives. They are despicable, corrupted creatures, and Ilias despises them, forbidding her true children from falling into lust and laying with the monsters.
... yeah, tell Granberia that story and prepare to be unconscious for the next few hours. Some monsters do prey without discrimination, but there's just as much variety among monsters as among humans, if not more. Granberia, for example? She was once a candidate for the throne of the Monster Lord, the mysterious, supremely powerful monster who holds undisputed authority over all monsters of the world, and is now one of the Four Heavenly Knights who serves her.
Personality-wise... well, she's serious. Very much so. The Heavenly Knight who aligns herself with fire, she has given herself over entirely to her swordplay during life, always watchful for someone able to actually challenge her mighty sword. Eternally calm and serene, she has at least some aspect of all four elements in her mentality and fighting style despite being the "fire" wielder of the Four. Terrifying in battle, she shows no mercy to her opponent, yet still holds enough control to avoid killing...
Granberia is an absolutely transcendent swordswoman. To this day only two people have ever bested her in combat; not even her fellow Heavenly Knights are on her level. Her calm face and demeanor ever radiate respect regardless of the enemy's skill; there is only one question. Did you stand up and face her, despite how obviously you're outmatched? Or did you flee like the coward you are? Face her and you earn her respect; cower and your lot is nothing but disdain and humiliation...
So... that's Granberia. A mere 25 years old, and already a terrifying opponent, yet not completely hating of humans, merely curious... she does hold a particular hatred for Ilias' flock, though, so Heroes beware... but show her respect and you'll know that of a true warrior...
