Phantom Breaker: Battle Grounds Ultimate

Japan's capital, Tokyo.

The mysterious man, Phantom, has been operating in the shadows in order to regain his immense powers, which have been sealed.

He granted a weapon called FA (Fu-mension Artifact) to young talented individuals, and enticed them into battle by promising them to grant their wish if they win in battle.

This is because the clash between the FAs will generate a distortion in space and time, creating an opening that leads to an alternate world. This opening will eventually unseal his powers.

Waka, the young daughter from the Kumon family belonging to a clan of exorcists rebelling against Phantom, and Mikoto, who offered cooperation, tried to stop this conspiracy, but lost him just before defeating him. In addition, Waka's younger sister Nagi has been kidnapped by Phantom.

Itsuki, who yearns to become the hero of Justice, and Yuzuha, a ninja who once managed to escape Phantom's seduction, also joins the fight, and the 4 girls set out on a search mission to track down Phantom and save Nagi.
