Chaos reigns at the training camp when the students of Lucrezia Academy are attacked by a mysterious group of people using strange magic. Among them, a masked man who seems to know the truth behind her reincarnation goes after Leticiel with the cryptic warning: "We are two people whose destinies are intertwined." With unexpected help from an ethereal being known as an Elemental, Leticiel's sorcery is able to push back the masked man's attack—but not before Zeke reveals that he, too, can wield the same dark power as the stranger.

With each secret that comes to light, more mysteries appear from the shadows. What is the truth behind Zeke's past, and why has he been hiding it from everyone all this time?
