Suzume needs to unify the four soul fragments, but can she trust Kazue's reincarnation?

For the first time in her life, Suzume has opened her heart to love. Even with her family in Hisato's clutches, she feels optimistic that with Kaito and her friends at her side, they'll conquer the darkness together. Their final task is to find the last soul fragment. But the Water of Kazue's soul has joined forces with Hisato, helping him grow his hybrid army. And even more troubling, she claims to be Kazue's reincarnation.

Kaito's enemies are trying to destabilize his reformed kingdom. And to make matters worse, the woman he loves thinks he's hung up on his past. Kazue's reincarnation has complicated his life, in more ways than one. He and Suzume need to be united in their fight against Hisato. While they squabble, Hisato's grip tightens on Akatsuki and his influence reaches farther. They have to defeat Hisato before his monstrous army grows too powerful and conquers all of Akatsuki.

Sealing Hisato requires resonance between all four fragments of Kazue's soul. To defeat against Hisato, they have to capture the water of Kazue's soul first. But when one of their own betrays them, it turns all their plans upside down. As anarchy consumes Akatsuki, their last hope lies in the flames of vengeance burning in Suzume's heart. But is she alone enough to defeat the darkness?
