A teenager wakes up in a world where every human is a statue, and his first instinct isn't to panic, it's to start rebuilding civilization from scratch using nothing but chemistry and willpower. The show moves fast enough that you're solving a new impossible problem every three episodes, each one a small victory that actually means something. It's for people who get excited about understanding how things work, not just watching things explode, though plenty of explosions happen anyway.
When a mysterious emerald flash petrifies every human on Earth, Taiju awakens millennia later to a world reclaimed by nature. Skyscrapers crumble beneath vines. Cities become forests. Humanity exists only as stone statues frozen in time. Then he finds Senkuu, the one person conscious through it all. While Taiju spent three thousand years trapped in rock, Senkuu spent months awake, obsessing over a single goal: rebuild civilization from nothing using nothing but science. What follows is equal parts survival thriller and chemistry lesson. Senkuu's encyclopedic knowledge clashes with Taiju's raw determination as they scavenge materials, experiment with ancient techniques, and gradually resurrect technology itself. Starting with water purification and fire, they work backward through human achievement to restore electricity, medicine, and industry. Each invention brings new allies back to life, and each revival shifts their understanding of what happened and who else might still be conscious. The show balances genuine tension with genuine comedy, treating scientific discovery as an adventure where the real enemy is entropy itself.
