— A revenge tragedy of the black-haired noblewoman, who burns sins to ashes with black flames —

Suddenly appearing, the invaders known as "Celestial Beings" pushed humanity to the brink of extinction.

These grotesque and massive beings ignored all calls for help and brought destruction everywhere. Human cities were burned one after another, and Earth was ruthlessly ravaged. Forests were burned, fields were poisoned, and the seas became a death world covered in an oily film.

In that moment of despair, a light appeared to save humanity.

"Magical Heart"

A miraculous gem that only the chosen maidens can possess. With its power, these maidens, who defeated the Celestial Beings, came to be known as the "Jewel Princesses."

Eventually, the academy city "Seika Renaissance Polis Fukkou," symbolizing the revival of humanity, was completed. Known as "Fukkou Academy," it became a new light illuminating humanity,where chosen maidens from around the world, selected as candidates for the Magical Heart, gathered.

However, all of this was a lie—

The black-haired noblewoman, Misogigahara Towa, who lost everything
was the true discoverer of the Magical Heart, her mother, the creator of the academy city, was killed, and her sister, who was turned into a monstrous experiment, begged to be killed by Towa herself.

— The enemy is the "Student Council" that controls the academy city.
— The successor of the traitor who took everything, the Student Council President, Akatsukinomiya Eris.

Clad in the black flames born from the Magical Heart, Towa plunges herself into a pitch-black revenge drama. As the Black Jewel Princess, she engages in a magnificent "dance battles" with the maidens who possess the Magical Heart.

Until the day she avenges her mother and sister and reclaims all the Magical Hearts—
