Shironeko Project ZERO Chronicle

The world is split between a kingdom of light in the sky and a kingdom of darkness on earth. As the King of Darkness devotes himself to war, monsters ravage his lands. A boy whose village was destroyed by monsters questions the king's rule.

Iris heads into battle as Bahl wages war against the Kingdom of White.

In the Kingdom of White, Iris reflects on her duties; in the Kingdom of Black, the Prince of Darkness enters a competition.

On a diplomatic mission to the Kingdom of White, the prince and Adel must carefully navigate the tense wartime atmosphere between their kingdoms.

Iris agrees to join forces with the King of Darkness to put an end to Bahl and his indiscriminate rampages. The forces of darkness rally to stop Bahl's assault, but they must hold out long enough for the two monarchs to bring him down.

Groza joins the prince and Adel in the Kingdom of White, bringing an offer to extend the peace between the kingdoms. While the two sides work to build their newfound friendship, Groza finds herself irritated by the prince's interest in Iris.
