終末のハーレム ファンタジア [Shūmatsu no Hārem Fantasia]

In this dark fantasy spin-off of World's End Harem, a plague has wiped out nearly all men, leaving a handful of survivors to navigate a world now dominated by women. Originally serialized by Shueisha in 2018, the series shifts the setting to a medieval fantasy realm, where magic and swordplay replace modern technology. Known for its mature themes and ecchi elements, the story follows a young mage who must confront political intrigue and monstrous threats while being one of the last males capable of continuing the human race. Its 16-issue run offers a self-contained saga that blends survival drama with high fantasy adventure.
