The official website for the World’s End Harem anime has announced that the anime’s production committee has delayed the anime’s premiere from October 8, 2021 to January 2022 due to a need to “closely examine” the anime’s production. Crunchyroll was scheduled to simulcast the anime during the Fall 2021 anime season.
Yuu Nobuta is directing the anime at Studio Gokumi and AXsiZ. Tatsuya Takahashi is in charge of the series scripts. Masaru Koseki is designing the characters. Shigenobu Ookawa is composing the music.
The story of the series is described as:
The Man-Killer Virus: a lethal disease that has eradicated 99.9% of the world’s male population. Mizuhara Reito has been in cryogenic sleep for the past five years, leaving behind Tachibana Erisa, the girl of his dreams. When Reito awakens from the deep freeze, he emerges into a sex-crazed new world where he himself is the planet’s most precious resource. Reito and four other male studs are given lives of luxury and one simple mission: repopulate the world by impregnating as many women as possible. All Reito wants, however, is to find his beloved Erisa who went missing three years ago. Can Reito resist temptation and find his one true love?
EDITED TO ADD: Anime News Network later reported that the first episode of World’s End Harem is scheduled air its first episode of October 8, 2021, but that Episode 2 and later are delayed to January 2022. However, the first episode will not stream online until January 2022.
