After Death, I Became Ultraman Gaia

Dying senselessly to save a stranger felt like the ultimate end. But for Oshima Reiya, it was just the beginning. Earth, exposed and vulnerable, became a cosmic battleground, relentlessly trampled by alien invaders and monstrous super beasts. Humanity, relying on foreign Ultra Warriors, teetered on the brink of annihilation. Then, a voice echoed in the void: Gaia, the living will of Earth itself. She offered Reiya a second life, not as a frail girl, but as the planet's own divine protector—Ultraman Gaia.
