High School DxD: Duality - Apotheosis

This is the story of Duality-the eternal dance between light and dark, good and evil-

And the Duality of Gods and Mortals.

It's the tale of two rivals: one fated to rise in the light, the other to fall into the abyss.

One born of the divine, the other forged from humanity.

As they journey through a world teeming with danger, their paths cross with gods, angels, yokai, demons, and all manner of supernatural forces. Every trial they face draws them nearer to their destinies-one striving toward celestial glory, the other descending into an ever-deepening shadow.

Their journey tests their strength, beliefs, and souls, shaping their fates in ways neither could have foreseen.

So then why is a dragon in the form of a gothic lolita clinging to him, asking for help her return to her silence?
