Isekai Sex Boutique begins with the protagonist being transported to a fantasy world, an act orchestrated by a bored goddess. The deity watches the protagonist’s subsequent attempts to survive solely for her own amusement. The character, with her knowledge of sex toys, discovers a business opportunity in this new environment. This leads to the establishment of a specialty shop, a business venture focused on creating and selling products for carnal pleasures.

Endless Forest Dream — a convoy of heavily armored vehicles cautiously navigates the winding trails of a forest teeming with grotesque tentacles. As they near a clearing encircled by an impenetrable wall of writhing appendages, countless eerie creatures sway and undulate, their slimy bodies glistening in the dim light. They seem to be in a frenzy, eagerly anticipating the next thrilling event in their dark world. Amid the armed soldiers guarding the vehicles, a solitary figure emerges from one of the cars—a young woman dressed in a fragile outfit, her eyes shimmering with tears. As she steps onto the forest floor, the convoy roars to life and disappears into a cloud of dust, leaving her standing alone. Her heart races as she turns for a final look at her old companion, who watches her departure with a mix of sorrow and pity.
