Transmigrated to a primitive era, Kawahara was a dying patient. He barely survived, only to witness grotesque Gurongi monsters brutally hunting his new tribe. This wasn't primitive society; it was the terrifying, monster-ridden dawn of the Kamen Rider Kuuga world! Worse, his own body held a secret: an incomplete Aguru Belt. It granted him immense, unstable power, but at the cost of violent urges and a horrifying, agonizing demise. He's a proto-Rider, not yet fully Kuuga, battling internal corruption while surrounded by a vulnerable, primitive people teetering on the brink of extinction. Now, the tribe's chosen warrior, Riku, is set to inherit the complete Kuuga power. Kawahara must become his reluctant mentor, teaching him to fight the Gurongi. But how can he guide a hero when his own power threatens to turn him into the very monster they fight? His survival isn't just about him; it's about forging the first hero, or watching an entire era fall.
