Riding a Giant-Sized Beauty to Save the World

As the last man in the world, I woke up one rainy night and, the next second, found myself in the ruins of a city. A voice led me to the corpse of a gigantic girl. I was stunned, and the sight before me made me forget the danger behind me. A giant, beautiful girl named Lulu La was calling out to me to guide her. It seemed her goal was to take me away. Just as we were about to leave, an image flashed through my mind: Lulu La being attacked.

Before my eyes, up ahead, was an even bigger and more terrifying monster.
