The fierce confrontation among the Kanto high schools reaches new heights with the awakening of dragons in the Kyousho and Seito Academy's leaders, Moutoku Sousou and Gentoku Ryuubi. However, the power balance between these two institutions and their main opponent, Nanyo Academy, is jeopardized when Shimei Ryomou seizes a mysterious dragon orb in China. It is said that the orb grants its strength to a dragon wielder, and Shimei hopes to save Nanyo Academy's leader Hakufu Sonsaku from the adverse effects of her unstable gift. Meanwhile, Moutoku's powers completely consume him, and he loses control over his own body to the Demon King's soul, whose unlimited ambitions endanger the stability of the region and the safety of his allies. In the face of growing tensions to claim the dragon orb, Hakufu and Gentoku will have to put aside their differences and work together to thwart Moutoku's demonic plans.

The story centers on the Platonic Heart, a jewel that—according to an old urban legend—can grant any wish when collected. Only a chosen few are allowed to compete in the Platonic Heart hunt, and high school junior Aya Iseshima is one of 11 girls and women who are taking part.

After her parents were brutally murdered, school girl Sawa was taken into custody by Akai and Kanie, a pair of detectives assigned to her case. Corrupt and immoral, they train the girl to become a weapon, dangling the promise of vengeance in front of the hapless orphan. From celebrities and politicians to influential businessmen, Sawa is tasked with assassinating targets selected arbitrarily by her crooked overseers. She executes every mission without fail, and her distinctive weapon has become infamous among the city's police officers. Physically abused by Akai, who is no more righteous than her victims, Sawa begins to dream of a life unhindered by the shadow of her guardians. One day, Sawa meets Oburi, a fellow orphan and vigilante. They quickly form a bond born of desperation and disgruntlement at the unjust world, envisioning a future free from the stain of murder.
