Zenshuu.

Natsuko Hirose rises rapidly through the animation industry, becoming a director known for both her talent and her determination to control every detail. After collapsing from food poisoning, she awakens inside A Tale of Perishing, the story she loved as a child, standing face to face with characters whose tragic fate she already knows.

When the Voids that are destined to destroy the world appear, Natsuko discovers that her drawing tools can turn what she animates into reality. Her knowledge of the story gives her a chance to prevent disasters she knows are coming, but every alteration makes the future less predictable. For the first time, Natsuko is not creating a world from the outside; she is living inside one, and must decide how far she can rewrite a story she loves without erasing what made it meaningful to her in the first place.
