Before petrification, Mirai was clinically brain-dead, sustained by systems that had already failed her. Tsukasa's entire empire, his ideology, his war against science. It was all built for one person. Every statue he shattered, every warrior he revived, every word of his anarcho-primitivist manifesto was scaffolding around the same fact: keep Mirai safe, at any cost.

The irony cuts deep: the science Tsukasa spent months fighting to destroy was the only thing that could save her. He'd built an empire to stop Senku. Then he had to trust Senku with the one thing that mattered.
