Overview

In a near-future world where a pandemic has drastically reduced the male population, humanity faces a crisis of declining birth rates. On a remote island town called Kawashima, the government has established an advanced academy where “practical sex education” has become mandatory as part of national policy.

You play as a student who moves to the island to attend this academy. What begins as a rural slow-life of fishing, crafting, and exploring soon intertwines with unique lessons: classmates, seniors, and adults are paired for daily “practice sessions” aimed at countering depopulation.

The game combines:

• Story & Setting: A mix of slice-of-life island survival, school life, and romance.
• Gameplay: Exploration, crafting, farming, fishing, and interacting with townsfolk.
• Characters: 15+ heroines including classmates, seniors, and adults, each with distinct personalities, hobbies, and storylines.
• Events: Over 100 conversation events, island festivals, and side quests with townspeople and even anthropomorphic animals.
• Content: A large volume of scenes (HCGs and events), ranging from standard romance to more niche situations.

Players can build relationships, unlock events, and enjoy both the everyday island lifestyle and the academy’s unusual curriculum.
