WorldEnd: What are you doing at the end of the world? Are you busy? Will you save us?

WorldEnd: What are you doing at the end of the world? Are you busy? Will you save us? is a TV anime series blending fantasy, drama, romance, and mystery, based on the light novel by Sukeno Akira. Set in a world where humanity has all but vanished, young girls known as Leprechauns are the last weapons standing against monstrous threats. When veteran soldier Willem Kmetsch meets Chtholly Nota Seniorious, an unlikely bond forms amid the ruins of civilization. Produced by Satelight under director Kazuya Wada and series composition by Toshizo Nemoto, the series delivers a hauntingly beautiful narrative that balances tender slice-of-life moments with supernatural peril.

Five centuries ago, humanity was driven to extinction by terrifying creatures known only as 'Beasts'. The races that survived built their civilizations atop floating islands drifting high in the sky, beyond the reach of most of these monsters. Yet even in these heavenly refuges, the threat of invasion never truly fades. The only ones capable of wielding the ancient armaments needed to repel the Beasts are a group of young girls called Leprechauns—soldiers whose lives hang by a thread, always one battle away from oblivion. Into this world of fragile existence steps Willem Kmetsch, the sole surviving human, who lost everything in a desperate last stand five hundred years ago and has only just awakened from a deep, frozen sleep. No longer able to fight, Willem finds himself in an unexpected role alongside girls like Chtholly Nota Seniorious and Nephren Ruq Insania. In a world forever changed, he must discover what it means to protect something precious—not with a sword, but with something far harder to hold onto.
