Sex Lesson Island

About Sex Lesson Island

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.
