Harem-tou e Youkoso!

In an exciting industry announcement, prominent animation label Collaboration Works Studios has officially confirmed that Episode 1 of the highly anticipated fantasy anime series Harem-tou e Youkoso! (Welcome to Harem Island!) is scheduled for its official global arrival on July 31.

The provocative narrative introduces a refreshing twist to the genre, seamlessly combining high-stakes wilderness survival elements with a dynamic trapped-in-another-world Isekai premise. The story follows a tight-knit high school Exploration Club whose planned vacation to a beautiful Southern resort completely shatters when a violent shipwreck strands them on a mysterious, uncharted island. To their absolute disbelief, they quickly realize they have been forcefully transported to an entirely different dimension.

Following a strange encounter with a local deity inside a dream, the club members—consisting of **one lucky young man and three beautiful girls**—are officially tasked with a monumental cosmic mission: to revive this magical domain and transform the legendary “Harem Island” into a bustling, popular tourist paradise. Surrounded by bizarre, undiscovered flora and a local population where 99% of the residents are gorgeous, voluptuous mature women, their wild new routine begins behind closed doors.

However, as intense anxiety over returning home builds within the group, the terrifying fear of the unknown pushes their suppressed emotions to an absolute breaking point. In a moment of panic, the club’s pristine schoolgirl breaks all boundaries, aggressively throwing herself into the arms of the boy she has secretly loved for years, unleashing a passionate, raw confession of love that will permanently alter the dynamics of their desperate island cohabitation.
