Summer Beach is a spiritual successor to Sexy Beach, an adult 3D dating simulation game.

In the summer after high school graduation, with no clear plans for the future, you arrive at the seaside town of Minamihama Port, far from the mainland.
Expecting to coast through the summer working part-time at your aunt’s small drink stand, you’re immediately greeted by the "Minamihama Port welcome": your luggage gets stolen, your rent is a scam, and your daily wage is unfairly low.
Just when you think your life is about to become a daily grind in the "garbage disposal group," you realize—
This is exactly where your fate begins to change.

In this game, you will:
◆ Develop relationships with girls of diverse personalities
Asami Misaki: Your sharp-tongued, soft-hearted cousin who distrusts men. Cold and sarcastic, yet she might knock on your door late at night.
Mizuno Natsuki: A mature and cheerful older-sister type who can lighten the mood instantly.
Ozawa Aoi: A mysterious girl who feels inexplicably close to you, clingy like a cat.
Oshima Akemi: A free-spirited, independent fitness trainer who loves the ocean.
Ozawa Sayaka: An intellectual, short-haired, gentle, and reserved bookstore clerk who enjoys solitude.
And more characters await your discovery.
Each has her own story, events, and hidden feelings.
Every choice you make may change their attitudes toward you.

◆ Manage a "Beach Maid Drink Stand"
Work, purchase supplies, decorate, and attract customers to revive the drink stand before the peak season!
You can change the girls' outfits, assign shifts, and unlock special services and holiday events.
(Of course, you might also continue to be exploited by your aunt as cheap labor.)

◆ Explore the small open world of Minamihama Port
Freely roam the town:
Fish at the pier
Rent a motorcycle for a ride
Go diving at the beach
Unlock resident requests
Interact with the island’s mysterious legends
Hidden secrets, strange rumors, and even some "unexplainable presences" await your discovery.

◆ A youthful seaside tale
A summer woven with humor, healing, romance, and mystery.
Will you choose a peaceful life or rewrite the future for yourself and the girls?
Every day in Minamihama Port could be a new turning point in your life.
