A girl loses everything, all in one day. Her village, and even worse—her father...

In their place, she acquires a new power. When she takes up a sword to protect herself and her loved ones, she discovers that it is "cursed" and holds immense power.

Having obtained something that could shake the very foundations of the nation, the girl has no choice but to live on the battlefield.

The ultra-nationalistic military academy, Nirvana, becomes her new home. There, young men and women who excel in combat gather to compete and sharpen their skills, regardless of their background.

She meets new people, forges strong bonds, and finds what she thought she'd lost: a place to belong.

This is the story of the girl and the talking cursed sword by her side.
