Rock-Hard Rehab: How to Survive a Hospital Harem

After being stranded on a deserted island with you…
Ai, an energetic tsundere-type gal
Rena, a cool and laid-back gal
Narumi, a carefree and mysterious gal
Here, it’s just you and the three gals.
Let’s enjoy a naughty harem life together!

Burned out from studying, a man checks into a hospital in search of rest. But this place is far from ordinary. What begins as a quiet stay soon slips into something surreal - -where the line between reality and nightmare starts to blur.

With every passing night, doubts grow. You must question what's real and slowly uncover the hidden truth buried within these halls. Only by surviving all five nights of despair will the full picture come into view.
 
During the day, you’ll explore the hospital, meet eccentric patients and staff, and progress through various quests. Through conversations and events, you'll uncover fragments of the story and gather crucial clues.

But when night falls, everything changes. Those familiar faces transform into terrifying creatures. You’ll have to hide, run, and make clever use of limited items and your surroundings if you hope to survive until morning.

Treat patients, tackle time-limited medical events, and gradually expand your hospital as you recruit 9 adult female doctors and nurses, each with her own distinct personality. Manage your hospital by day and explore a mysterious trading market by night—life as a hospital director is always full of surprises!
From everyday conversations to one-on-one dates, discover a side of each woman that she reveals only to you as your bond grows. With beautifully crafted cartoon-style art, multiple character-specific storylines, and over 50 hours of gameplay, every step closer brings a little more heart-fluttering anticipation.

In the game, various patients come to the hospital every day. More new patients are admitted by expanding facilities, and difficult and complicated diseases are treated by researching new technologies. While operating, you can also interact with nurses and doctors in various ways. Every girl has weaknesses, and you can attack them by finding their weaknesses. Whether to make the hospital an ordinary orthodox hospital or a place to provide special services for members. Everything depends on you.

The protagonist and his childhood friend, Nanami Mitsuki, get caught in a storm during their trip and are stranded on a deserted island.
As they live with the goal of simply surviving, their sexual urges gradually build up…
To relieve those urges… they start helping each other masturbate!?
Will they be able to build a boat and escape the island without being consumed by their desires…!?
