A fairy-raising environmental simulation set in a future where humanity attempts to make hostile planets suitable for habitation. The player raises mysterious fairy-like lifeforms inside an artificial garden and influences their development by adjusting air and water temperatures, placing vegetation, playing music, providing items, and teaching them through special tablets. Each fairy develops different elemental abilities according to its environment and treatment. The player must understand the fairies’ individual preferences, maintain their condition, and develop their powers to complete a series of planetary-development scenarios.
