What could be sweeter than a quiet life on a distant island? Exactly: a life where your criminal past knocks on the door, the local hospital is falling apart before your eyes, and a mysterious shark-girl's tail flickers in the window. You are Ray Nochi, a former fixer who, at your uncle's invitation, lies low back home and suddenly finds himself running a forgotten hospital. From day one, debts pile up, equipment is broken, and nurse Mari never misses a chance to tease you, all while a strange pain nags at your chest. This is a nonlinear visual novel with an open world and life-sim/management elements: explore the island, get the hospital back on its feet, upgrade your home, earn money, and—if you dare—try to build a life with the unpredictable guest with the shark tail.
