Riku Barusak is a hard-working child. Despite possessing an innate superior physical strength and having withstood harsh training she fails to unlock her talent as a spiritualist. The failure results in her being thrown away by her family.

Abandoned, the only ones that extended a hand to her were the demons, the greatest enemies of the human race. Serving under them as a soldier she becomes a weapon of human slaughter, a fiend that should never have existed.

The god king of Xiaoting in the upper realm fights down, and the spirit of the mixed dragon spirit is reincarnated on the earth, runs rampant in the city, and then fights in the sky.

Those who obey me prosper, those who oppose me perish!

- Description from novelbuddy

When she stands, she’s like a white peony. When she sits, she’s like a tree peony. When she walks, she’s like a lily flower. And when you look her in the eyes, she’s like the Great King of Terror.

Despite having the qualities to be a peerless bishoujo, because of the look of her eyes and that atmosphere of hers, she’s feared by others; such a girl is forcefully sent to another world.

Being told that she would be granted a wish as a special favour, the girl made a wish────

“Make my eyes and atmosphere normal please.”

This is a story recounting the lifestyle in a parallel world of a girl who would be perfect (probably) if just her one weakpoint was overcome.

A fantasy comedy with magic, dungeons, and a hero and demon king(candidate) who she gets tangled up with.

King Grey has unrivaled strength, wealth, and prestige in a world governed by martial ability. However, solitude lingers closely behind those with great power. Beneath the glamorous exterior of a powerful king lurks the shell of man, devoid of purpose and will. 

Reincarnated into a new world filled with magic and monsters, the king has a second chance to relive his life. Correcting the mistakes of his past will not be his only challenge, however. Underneath the peace and prosperity of the new world is an undercurrent threatening to destroy everything he has worked for, questioning his role and reason for being born again.
