After the shocking incident with Aina, Azuma tries to repair his relationship with her. But Aina has closed herself off to him and is avoiding him. Meanwhile, Riguel and Azumi and Ayase and Suiger are fighting an unknown enemy.

One of the Twelve Apostolic Angels of the White World, Aquarius Gambriel, suddenly appears before Azuma. But Fierte is uneasy at the appearance of what should be a friend.

A mysterious army appears in Kobe without warning. A state of emergency is declared, and a feirce battle between Z/X and Z/X begins. Azuma Tennoji fights with his partner Z/X Fierte to protect his beloved Kobe.
